5 Email Subject Line Tips for Authors

Your subject line is the first thing readers see. A great one gets your email opened. A forgettable one gets it buried. Here are five tips that work especially well for authors.

1. Keep It Short and Specific

Aim for 40 characters or fewer. Mobile devices truncate longer subject lines, and brevity forces clarity. Instead of "My Thoughts on Writing and Some News," try "New chapter preview inside."

2. Use the Reader's Name Sparingly

Personalization can boost open rates, but overusing it feels robotic. Save it for moments that matter — like a launch announcement or a personal thank-you.

3. Create Curiosity Without Clickbait

Readers are smart. Tease what's inside without misleading them. "The one thing I changed in my writing routine" works. "You won't BELIEVE what happened" does not.

4. Test Two Versions

AuthorSend lets you A/B test subject lines with a portion of your audience before sending to everyone. Use it. Small differences in wording can lead to meaningful changes in open rates.

5. Match the Tone of Your Books

Your newsletter is an extension of your author brand. If you write cozy mysteries, your subject lines should feel warm and inviting. If you write thrillers, a little tension goes a long way.

Start Experimenting

The best subject line is the one your readers respond to. Track your open rates in AuthorSend's analytics dashboard and iterate from there.
