Three things that help

1

Add info@karengrill.com to your contacts

I'm sending a few short tips on subject lines and preview text over the next few days. Adding me keeps them out of spam.

2

Bring a real email you're working on

The Studio works best when you have something specific. Paste in a subject line you're already writing and see what it surfaces.

3

Check your confirmation email

The link to the Studio is also saved there, so you can come back to it any time without hunting for this page.

A few things worth knowing before you start

The most common mistake

Most people write preview text that repeats the subject line. Subject says "3 ways to grow your list," preview says "3 ways to grow your list." That wastes your second chance to earn the open.

If you leave preview text blank

Gmail, Outlook, and Apple Mail fill it in for you. Usually with "View this email in your browser" or the first line of your email. That is wasted real estate on every send.

What the preview text should do

Extend the subject line. Add a benefit, a specific detail, or context the subject line did not have room for. They work as a pair, not two separate lines.

Length on mobile

Subject lines under 45 characters and preview text under 90 characters display reliably across most email clients and devices.
