Introducing The AI Subject Line Generator

Never write a subject line again, with our new free AI-powered tool

4 May 2023

Your subject line has one job: Get people to open your email.

But the reality isn’t always so easy.

Statistics for 2023 report average open rates of between 21% and 33%. That’s potentially 2 out of every 3 subscribers not opening your email even at the best of times! 

A snappy subject line is how to change that. EcoSend's new AI Subject Line Generator is here to make it happen.

Use our new Subject Line Generator to increase your open rates. Plus save time and energy.

Based on the success factors of millions of opened emails, we’ve created the technology to help you write quicker and more impactful email subject lines.

Here’s more about how we made the EcoSend Subject Line Generator, plus how to get started!

More About EcoSend Subject Line Generator 

Ever wonder how the magic of AI works?

Well in the case of the EcoSend Subject Line Generator, we’ve fused our own knowledge of email marketing, with specific data trends which are more likely to lead to higher open rates. 

Something all good subject lines have in common is that they pique curiosity. They can be related to new products, announcements, events or opportunities for your users.

When your subject lines encourage a specific action (i.e. to make a purchase), the data shows these emails are more likely to be opened. 

Such subject lines make use of ellipses, dashes, and exclamation points to create a sense of urgency and excitement.

Most of the best subject lines we’ve tested are short and snappy at between 5 and 20 words, though the shorter the better to keep reader's interest.
