Write better subject lines with AWeber’s NEW Subject Line Assistant—now with AI!

Updated July 9, 2024: The Subject Line Assistant now writes subject lines for you, based on the content of your email.

One of the most important things about any email you send is the subject line. A good subject line can make the difference between someone being curious enough to open or choosing to skim right past.


I write our weekly newsletter with my friends Chelsea and Sean, so I’m personally familiar with how hard and stressful it can feel when it comes time to write a good subject line. Thankfully I have the support of the email experts at AWeber to review and help me.

We’ve just released a subject assistant that takes the same expertise I benefit from and packages it up to help you feel more confident when it comes time to hit the send button.

The subject assistant does a few great things:

1 – Makes sure you never send with an incomplete subject line or missing preview text (the summary text that appears alongside your subject line in inboxes) by consolidating them into a single panel.

2 – Helps you write better subject lines by giving you feedback based on the best practices we’ve learned over the last 25 years as an email marketing platform.

3 – Best of all, the Subject Line Assistant will now generate winning subject line suggestions for you  based on the content of your email. If you’re like me and can sometimes feel stuck trying to come up with a catchy, effective, and honest subject line this is a game changer. You can even alter the tone to match your writing style.

The Subject Line Assistant is available to everyone today, so you can jump right into any draft and use it to write better subject lines right now.
