What topic are we tackling for this one? And before we dive in, tell me a real story from your experience that connects to whatever direction you're thinking.
You have the blog topics that you keep track of

Let me check what's in the pipeline. Searched memory, viewed a file
Searched memory, viewed a file
Based on the map and what's already published (Does Switching Email Platforms Fix Spam, How Often Should Coaches Email, Email Deliverability Fix), the next unwritten post from the plan is:
"What Is Domain Reputation? (And Why It Matters More Than Open Rates)" Slug: /what-is-domain-reputation
This is a Phase 1 deliverability cluster post. It's where your Email Trust Stack thinking comes in, and it links up to the spam pillar and over to the strategy pillar.
Before we write it: do you have a real story from your experience with domain reputation? A client who tanked theirs, someone who obsessed over open rates while their reputation was quietly tanking, anything like that?

I asked a blog finder program I'm in and here were some of the ideas
10:26 AM
Good list. These skew toward hire-intent and buyer-awareness content, which is a different angle than what's in the cluster plan so far.
A few of these stand out as strong fits for where your site is right now:
Strongest for SEO + cluster building:
#3 "How Long Before Email Marketing Shows Results?" - great search intent, low competition likely, strategy cluster
#13 "Can Email Marketing Help Fill My Coaching Programs?" - high buyer intent, ties directly to why coaches care about email
#15 "How to Get More Booked Calls Through Email?" - very specific to coaches, Pinterest-friendly
Strongest for your authority positioning:
#11 "How to Know If Email Marketing Is Working?" - overlaps with your metrics posts but from a different angle
#18 "How to Turn Email Subscribers Into Paying Clients?" - conversion focus, strong for coaches
My recommendation: Before adding these to the plan, I'd still write "What Is Domain Reputation?" first. It's the one gap in the deliverability cluster that weakens the internal linking structure. These new ideas fit better as strategy cluster posts once that gap is closed.
That said - do any of these feel urgent to you, or is something from your current client work making one of them more timely right now?
ok
10:27 AM
So - domain reputation it is.
Before we write anything: do you have a real story from your experience that connects to domain reputation? A client situation, something you diagnosed, a pattern you kept seeing? Even a rough memory works - just talk it out.
The usual situation is that people don't even know that they have a problem with their domain reputation there are some people who come to me who we're looking at it from the website and they saw that they were on a block list and that also affects your e-mail reputation your website domain and your e-mail custom domain are connected and and affect one another and so um they came they first were looking for their website because they were having issues and their website builder was helping them um but then what happened was the website designer had said ohh this could also affect your emails and so that's when they reached out to me and so we had to work first to they did have some issues with their e-mail authentication so we had to fix that but then we also had to talk about OK now how do we rehabilitate so the website designer was working on things from his end and to repair that but then we developed a strategy for him first strategic planning strategic forming for his domain to slowly fill it up we cleaned his e-mail us we fixed the authentication records all of that we also gave him the tricks and things to kind of benchmark moving forward and we checked every month and so we looked like he was able to rehabilitate his domain reputation something that I often recommend to is to have a second domain that's very close to your first domain so let's say it's e-mail marketing.com it's a the e-mail marketing.com so that if anything ever goes wrong you could switch to a fresh domain which again has issues and there are certain context that you would do this but it's close enough that if people got the e-mail they wouldn't necessarily notice that it's different that way in case the domain is so bad you can't or it's going to take a long time to rehabilitate you're almost better to start with a fresh one or if you've been slowly warming that over time then you have a second backup domain

That's a great story. A few quick follow-up questions so I can shape this right:
Q: The client who found the blocklist through their website - can we use that as the opening story, or do you want to keep it more general?
A: Yes, use it as the opening story
Q: The backup domain strategy - how do you want to position it?
A: Somewhere in between - situational
Q: Where does domain reputation fit in your TEMS framework?
A: It spans both - I'll explain in my voice

Done. Here is what is in the post:
Structure: Full template with TL;DR, Short Answer, definition, 6 reputation signals, the rehabilitation process, backup domain (positioned as situational), myth blocks, diagnostic checklist, 6 FAQs, If You Only Fix One Thing, CTA box, Key Takeaways, pre-optin.
Your story: The client who found the blocklist through her website builder is woven into both the definition section and the rehabilitation section. It grounds the post in a real scenario without being too specific.
DMARC reporting: Mentioned in the signals section and gets its own FAQ question, consistent with your content differentiation principle.
Internal links: Up to both pillars, sideways to the SPF/DKIM/DMARC post.
Flags for your review:
The phrase "systematically" in the rehabilitation section - swap if it sounds too polished
The backup domain section is fairly brief by design. Let me know if you want more depth there.
Blog image text options for this post:
"Your emails land in spam before anyone opens them." - shows the problem before the solution
"Domain reputation: the score your email never shows you." - my recommended pick, because it captures the invisibility problem that is the heart of your opening story and makes someone curious enough to read
"Open rates won't tell you this." - short and provocative, works well as a contrasting hook

OK. can we create an image so that we can have some alt tags? And do we link out to outside sources I think we have internal links but let's make sure they are to some money pages as well.

Two quick questions before we do either:
Q: For the blog image - which text option do you want to use?
A: 2 or 3
Q: For external links - which outside sources do you want to reference?
A: all 3 but NOT dmarc.org

For the image, I'll make both options and you pick. And got it on the external links - Google Postmaster Tools, MXToolbox, and Google Email Sender Guidelines, all linked where they're naturally mentioned in the post.

MXToolbox - linked in the checklist and the FAQ answer about blocklists
Google Email Sender Guidelines - linked in the "What Signals Build Your Reputation" section near the authentication point, since that is where sender requirements live

what do you think of this feedback? ""

This is good feedback and I agree with the core of it.
The "Email Trust Score" framing is stronger than "domain reputation score" for your audience. Coaches and consultants understand trust. Domain reputation is the technical term underneath it. The graphic becomes an asset you use everywhere instead of a one-off illustration.
The gauge concept with the signals feeding into it is also accurate. Domain reputation is not the only signal, it is the central one that many signals influence. That distinction matters for your credibility.
A few things I'd push back on slightly:
The article title should stay as is. "What is domain reputation" is the search phrase people type. That is why the post exists. The graphic can use "Email Trust Score" language without the title changing.
The suggested subheadline "Domain reputation is one of the strongest factors influencing your email trust score" is a bit circular for a graphic. I'd simplify it visually.
Here is what I'd build:
A gauge graphic with navy and orange in your brand colors, showing Poor to Excellent, with the signals listed around it feeding downward into the gauge, and "Email Trust Score" as the headline. Clean, reusable, on-brand.
Want me to build that now? And then after we have the image locked, I'll update the HTML with the alt tag and add the three external links.
So I met in terms more of than the graphic, but the fact that, um, the domain reputation is one factor of many. It's not the only factor. So I don't wanna push too hard, or I'm gonna get pushback from email marketer people saying, you know, domain reputation is not the only thing. Um, it's one factor. And, yeah, you can build the image to
10:44 AM
You're right. The post as written actually does lean a bit hard on "matters more than open rates" in the title and has a few places where it implies domain reputation is the main deliverability lever. That needs a light edit to be accurate without losing the point.
The real argument is: most coaches obsess over open rates while ignoring domain reputation entirely. That is still a strong angle. It just needs to be framed as "this is the signal you are probably ignoring" rather than "this is the only signal that matters."
I'll do three things:
Light edits to the post to soften any overreach on domain reputation being the deciding factor
Build the Email Trust Score gauge graphic
Add external links and alt tag
Let me start with the image, then do the post edits after so you can approve them. Ran a command, read a file

How does that look? If the layout and concept work, I can refine the styling.
Once you approve it, I'll:

Add the three external links (Google Postmaster Tools, MXToolbox, Google Email Sender Guidelines)
Add the alt tag for this image
Drop the image tag into the post HTML right after the intro section

what do you think of this feedback? "I think you're about 85-90% of the way there. The concept is strong and it matches your brand.
A few things jump out at me:
What's Working
1. The title is excellent "EMAIL TRUST SCORE" is much easier for your audience to understand than "Domain Reputation."
2. The gauge works People instantly understand gauges. No explanation needed.
3. The branding is consistent The navy and orange feel very "Karen Grill."
4. The factors are good SPF, DKIM, DMARC, engagement, complaints, blocklists, etc. are exactly the right inputs.
What I'd Improve
The gauge is a little too small
Right now my eye goes to the title first, then the bullet list.
The gauge should be the hero.
I'd make it 25-40% larger.
The graphic is really about:
How much do inbox providers trust your domain?
The gauge is the answer to that question.
Remove "Your Email Trust Score"
You already have the giant title.
Having another title above the gauge feels repetitive.
Instead put:
Inbox Provider Trust
or
Domain Trust Level
or nothing at all.
Make the bottom explanation larger
Currently:
Domain reputation is one of several signals inbox providers evaluate when routing your email.
That's actually a really important statement.
I'd move it directly under the bullet list and increase the font size.
Maybe:
Domain reputation is one of the strongest signals inbox providers use when deciding where your emails land.
That ties directly into the blog article.
Add visual connection between factors and score
Right now the factors and gauge feel like two separate objects.
You could add a subtle arrow:
SPF
DKIM
DMARC
Engagement
Complaints
↓
EMAIL TRUST SCORE
Even a faint dotted arrow would help.
The one thing I'd definitely change
The phrase:
Higher trust = better inbox placement
is accurate but a little weak.
I'd replace it with:
Higher Trust → More Inbox Placement
Lower Trust → More Spam Filtering
That's much more concrete.
One advanced idea
Since you're using this inside the article, consider putting a small inbox icon and spam folder icon under the gauge.
Poor ---------------- Excellent
📁 Spam → 📥 Inbox
People remember visuals more than explanations.
Overall, I think this is one of the better blog graphics you've made because it teaches something. Most blog graphics are decorative. This one actually helps explain the concept before someone reads the article. That's exactly what an in-article graphic should do."

10:47 AM
Solid feedback. All of it is actionable. Let me rebuild with these changes:
Gauge larger, centered as the hero
Remove the redundant "Your Email Trust Score" label above the gauge
Signals on the left with a downward arrow connecting them to the gauge
"Domain reputation is one of the strongest signals..." moved under the signals list, larger
Replace "Higher trust = better inbox placement" with the two-line version (More Inbox / More Spam Filtering)
Add inbox/spam folder icons under the gauge
Ran a command, read a file
Ran a command, read a file
Better? The gauge is now the hero of the right side, the signals connect down via the arrow, the note about domain reputation being one of several signals sits right under the list, and the inbox/spam placement labels are more concrete.
Once you sign off on this, I'll do the post edits: soften the overreach on domain reputation being "the" factor, add the three external links, and drop the image tag with alt text into the HTML. Email trust score graphic

do you like your version or this version better?
10:49 AM
This version is better. Honestly, no contest.
The icons next to each signal make it scannable in a way that plain bullet points don't. The gauge is cleaner and the color gradient reads immediately. The lower section with the spam folder and inbox envelope is much clearer than what I built. The dotted arrow connecting the signals down to the key statement works well visually.
The only thing I'd flag: the needle is pointing to roughly "Good/Excellent" range. That might read as aspirational rather than diagnostic. Depending on how you want to use it, a needle sitting in the "Fair" range might be more honest for the average coach who finds this post, since the whole point is that most people don't know where they stand.
But that's a minor detail. Use this version.
Now let me do the post updates. I'll:
Update the post copy to soften the "domain reputation is the deciding factor" framing
Add the three external links
Add the image tag with alt text pointing to this graphic

Yep, that's a completely different post on the same topic. Longer, more detailed, different structure, different client story. You have two "what is domain reputation" posts now, which is a cannibalization problem.

The existing post is stronger. Here is why:
It has a more detailed client story with real stakes (workshop registrations dropping). It has a comparison table. It has 7 FAQ questions versus our 6. The "4 Factors" framing is cleaner than our numbered list. The Final Thoughts section is sharper. And it is already live, which means it has whatever indexing head start it has accumulated.
The one thing our new post has that the existing one is missing: the image, the external links, and the corrected framing around domain reputation being one signal of several.
My recommendation: keep the existing post and update it with those three things. That is a 20-minute job versus starting over.
Specifically:
Add the Email Trust Score graphic with the alt tag
Add links to Google Postmaster Tools, MXToolbox, and Google Email Sender Guidelines where they are naturally mentioned
Check if the existing post has any "domain reputation is the only/main factor" language and soften it

What Is Domain Reputation? (And Why It Matters More Than Open Rates)
The hidden factor that determines whether your emails land in the inbox or disappear entirely.
Domain reputation is one of the strongest trust signals inbox providers use to evaluate your email, and it is the one most coaches have never checked. Most find out it exists when something goes wrong.
TL;DR: Domain reputation is a trust score tied to your sending domain, not your email platform. Inbox providers build it over time by watching your authentication setup, your engagement rates, your bounce rates, and your spam complaints. A strong reputation means your emails land in the inbox. A damaged one means they do not, no matter how good your subject lines are. You own this reputation. It follows your domain everywhere.
Short Answer: What Is Domain Reputation?
Domain reputation is the level of trust inbox providers have assigned to your sending domain based on your authentication, engagement history, list quality, and sending behavior. It is not tied to your email platform. It belongs to your domain. A low domain reputation is one of the most common reasons emails end up in spam, and it does not fix itself without deliberate action.
What Domain Reputation Actually Means
When you send an email, inbox providers like Gmail, Outlook, and Yahoo do not just read the message and decide whether it looks spammy. They look at who is sending it. Specifically, they look at your domain.
Your domain is the part of your email address after the @ symbol. If you send from hello@yourbusiness.com, your domain is yourbusiness.com. That domain has a reputation. Inbox providers have been building a profile on it every time you send.
They are asking: does this domain send emails people want to receive? Do subscribers open them, click them, reply to them? Or do they ignore them, delete them without opening, or mark them as spam? Is the authentication set up properly? Are there a lot of bounced addresses on this list?
The answers to those questions, accumulated over time, form your domain reputation. It is essentially a trust score, and it is one of the key signals that determines where your emails land.
Why Your Domain Reputation Belongs to You, Not Your ESP
This is the part most coaches miss, and it is the most important thing to understand.
A few years ago, your sender reputation was partly tied to your email service provider. Large platforms had established sending infrastructure and shared some of that credibility with their users. Moving to a new platform gave some senders a temporary lift.
That is no longer how it works.
Today, inbox providers evaluate your domain. Not Mailchimp. Not ConvertKit. Not whatever platform you are using. Your domain. That means your reputation travels with you when you switch platforms. It means a new account does not give you a fresh start. And it means the only way to improve your reputation is to change what your domain does, not where you send from.
This is your asset to build and your problem to fix.
If you have been thinking a new ESP will solve your deliverability issues, this post explains why the problem almost always lives at the domain level.
The 4 Factors That Build (or Damage) Your Domain Reputation
Inbox providers do not publish their exact algorithms, but the signals they watch are well understood. These four factors carry the most weight.
Authentication. SPF, DKIM, and DMARC records tell inbox providers that your domain authorized the emails being sent from it. Without proper authentication, inbox providers have no way to verify you are who you say you are. Missing or misconfigured authentication is one of the fastest ways to damage trust before you even send a single email. Google's Email Sender Guidelines make authentication a formal requirement for bulk senders.
Engagement. Inbox providers watch what subscribers do with your emails. Opens, clicks, replies, and forwards are positive signals. Deleting without opening, ignoring for long stretches, and marking as spam are negative ones. High engagement builds reputation. Low or declining engagement erodes it.
List quality. Sending to invalid addresses generates hard bounces. Sending to people who never opted in generates spam complaints. Both are red flags. A list that has never been cleaned, or that was built through questionable practices, quietly damages your reputation every time you send.
Sending consistency. Erratic sending patterns, going silent for months then sending a high-volume launch sequence, or suddenly ramping up frequency, look suspicious to inbox providers. Consistent, predictable sending builds the kind of pattern they recognize and trust.
Builds Domain Reputation
Damages Domain Reputation
SPF, DKIM, and DMARC all configured correctly
Missing or misconfigured authentication records
Consistent opens, clicks, and replies
Low engagement, ignored emails, deleted without opening
Clean list with valid, opted-in addresses
High bounce rates, spam complaints, unclean list
Regular, predictable sending cadence
Long silences followed by high-volume sends
Removing unengaged subscribers proactively
Continuing to email people who never open
What a Damaged Domain Reputation Actually Costs You
I worked with a coach who had no idea his domain reputation was a problem. He was not looking at analytics. He had not set up authentication properly. His list had never been cleaned, and over time it had accumulated hard bounces, spam complaints, and a lot of cold contacts who had stopped engaging years ago.
People started telling him they were not receiving his emails. He thought it was a platform issue and considered switching tools. But the problem was not the platform. His domain reputation had deteriorated to the point where inbox providers were routing his emails to spam or blocking them entirely.
The real-world cost was immediate. He ran workshops. Registration numbers dropped. He could not figure out why. After the fact, people would tell him they had never seen the invitation. The emails had not landed.
We worked through it systematically. First, we cleaned the list aggressively, removing hard bounces, long-term non-openers, and anyone who had complained. That alone reduced the drag on his reputation. Then we fixed his authentication records. Then we rebuilt his sending pattern using strategic warming: starting with small sends to his most engaged subscribers only, and slowly broadening the list as engagement signals improved.
Because the damage was severe, full recovery took about two months. But within a few weeks of starting the cleanup, deliverability began improving. By the time we finished warming, his emails were landing in the inbox consistently. Workshop registrations came back.
Nothing about his content changed. His domain reputation did.
What Most Coaches Get Wrong About Domain Reputation
Myth: "My email platform handles my sender reputation."
Reality: Your ESP handles sending infrastructure. Your domain reputation is yours. It is built on your domain's history, your authentication records, your engagement data, and your list quality. Switching platforms does not change any of those things.
Myth: "I would know if my domain reputation was bad."
Reality: Most coaches find out months after the damage is done, usually when someone tells them their emails are not arriving. By that point, the reputation has been declining quietly for a while. Low open rates are often the first visible signal, but they are easy to misread as a content or subject line problem.
Myth: "A new domain fixes the problem."
Reality: Starting a new domain gives you a blank slate, but a blank slate is not the same as a good reputation. A brand new domain has no history, which means inbox providers treat it with caution. You still have to warm it up properly and build trust over time. And if you move your list without fixing the underlying issues, the same problems follow.
Myth: "Open rates tell me whether my reputation is healthy."
Reality: Open rates only measure people who received your email and opened it. They tell you nothing about the emails that were filtered to spam before anyone saw them. A reputation problem is often invisible in your open rate data until it becomes severe. You need authentication data and reputation monitoring tools to see the full picture.
How to Check Your Domain Reputation
Check your authentication records. Confirm that SPF, DKIM, and DMARC are all configured correctly for your sending domain. Your email platform's settings or MXToolbox will show you what is in place and flag anything missing.
Set up Google Postmaster Tools. If a meaningful portion of your list uses Gmail (most do), Google Postmaster Tools shows your domain reputation directly: High, Medium, Low, or Bad. It also shows your spam rate and authentication pass rates. Free to set up.
Review your bounce rate. Hard bounces above 2% are a signal worth acting on. If your platform shows a high bounce rate, your list needs cleaning before you send again.
Check your spam complaint rate. Aim to stay below 0.08% per send. Above 0.1% is a serious problem. Google's Email Sender Guidelines use 0.1% as a threshold for enforcement action.
Look at engagement trends. Declining open and click rates over several months, not just one bad send, can indicate that inbox providers are filtering more of your emails before they reach the inbox.
Run a deliverability audit. Tools like GlockApps or Mail-Tester show you where your emails are landing across major inbox providers. Use these periodically, not as a substitute for real engagement data.
A practical walkthrough of the tools and steps to find out whether your emails are reaching the inbox or getting filtered before anyone sees them.
How to Rebuild a Damaged Domain Reputation
If your reputation is already damaged, there is a clear path out. It takes time and patience, but it works.
Fix authentication first. Before anything else, make sure SPF, DKIM, and DMARC are properly configured. Sending without authentication while trying to rebuild reputation is like trying to fill a bucket with a hole in it.
Clean your list aggressively. Remove hard bounces immediately. Remove anyone who has not opened an email in 90 to 120 days. Remove contacts who have complained. This is not optional. Every send to a dead or disengaged address makes the problem worse.
Start with your most engaged subscribers only. Do not send to your full list while rebuilding. Identify the subscribers who open consistently, and start there. Small sends to highly engaged people generate the positive signals inbox providers need to see.
Warm up gradually. Increase your send volume slowly over several weeks. This is the same principle as warming a new domain. You are re-establishing a pattern of trustworthy behavior, and that takes time to register.
Monitor closely. Watch your Google Postmaster Tools dashboard, your bounce rate, and your complaint rate throughout the process. You are looking for the reputation rating to move from Low or Bad toward Medium and eventually High.
Severe cases take two to three months to meaningfully recover. Mild cases can improve faster, especially once authentication is fixed and the list is cleaned. The work is not glamorous, but it is the only thing that actually works.

Frequently Asked Questions
How long does it take to build a good domain reputation from scratch?
For a brand new domain, expect four to eight weeks of deliberate warming before you have a reputation strong enough to support consistent inbox placement. You start with small sends to engaged subscribers, increase volume gradually, and monitor engagement signals throughout. Rushing this process, by sending to your full list immediately, is one of the most common mistakes new senders make.
Does domain reputation affect all inbox providers the same way?
Each inbox provider maintains its own reputation data. Your reputation at Gmail is separate from your reputation at Outlook or Yahoo. Google Postmaster Tools shows your Gmail-specific reputation. There is no single universal score. This is why testing across providers matters, and why a deliverability problem at one provider does not always mean a problem everywhere.
Can a high volume of unsubscribes damage my domain reputation?
Unsubscribes themselves are not a reputation signal the same way spam complaints are. An unsubscribe is actually a healthier outcome than a spam complaint, because the subscriber is opting out cleanly rather than flagging you. That said, a sudden spike in unsubscribes after a send is a signal that something about that email missed the mark, which is worth investigating for content and list quality reasons.
Is domain reputation the same as sender score?
No. Sender score is a third-party metric produced by tools like Validity. Domain reputation is what inbox providers like Gmail actually use, and they do not publish a single numerical score. Google Postmaster Tools gives you a qualitative rating: High, Medium, Low, or Bad. These are different systems measuring related but distinct things. Focus on Google Postmaster Tools data over third-party scores for the most actionable picture.
Does using a custom sending domain through my ESP help?
Yes. Many email platforms let you authenticate sending through your own domain rather than a shared platform domain. This is worth setting up. Sending from a shared domain means your reputation is partly influenced by other senders on that infrastructure. Sending through your own authenticated domain gives you full ownership of your reputation signals.
What spam complaint rate is considered dangerous?
Google's Email Sender Guidelines flag a spam complaint rate above 0.1% as a threshold for enforcement action. The target is to stay below 0.08% consistently. Even a single campaign that pushes above 0.1% is worth investigating. If your rate climbs above 0.3%, you are in serious territory that can affect deliverability across your entire list.
Will cleaning my list hurt my deliverability in the short term?
It might look that way on paper. When you remove inactive subscribers, your open rate percentage often increases because the dead weight is gone, but your raw open numbers may drop temporarily. What actually happens to deliverability is positive: you are reducing the low-engagement signals that were dragging your reputation down. Short-term discomfort in metrics, long-term improvement in inbox placement.
If You Only Fix One Thing
Check your authentication records today. Confirm that SPF, DKIM, and DMARC are all in place and configured correctly for your sending domain. Authentication is the foundation everything else sits on. Without it, nothing else you do to improve deliverability will stick.
Final Thoughts
Domain reputation is not a technical detail you can delegate or ignore. It is the infrastructure your entire email strategy runs on. Every send either builds it or erodes it. Every bounce, every complaint, every ignored email is a data point inbox providers are collecting about your domain.
The good news is that it responds to deliberate action. Clean your list. Fix your authentication. Send consistently to people who actually want your emails. Those are not complicated changes. They are just ones most coaches never make because they did not know the problem existed.
Do not wait until people tell you they are not receiving your emails. By then, the repair work is harder and slower. Check your foundation now, while it is easier to fix.
Domain reputation is one of the strongest trust signals inbox providers use when deciding where your emails land. It is not the only signal, but it is one most senders never check.
It belongs to your domain, not your email platform. Switching ESPs does not reset or improve it.
The four biggest factors: authentication setup, engagement rates, list quality, and sending consistency.
