Real examples of how AI-powered email marketing works

The use of AI in email marketing is still in its early stages. Even so, the technology has already demonstrated huge potential in many areas. 

Check out these real-world scenarios to see how AI is improving email marketing.

AI-generated subject lines

It is a one-liner that summarizes the email’s contents and entices the receiver to open it.

Al can gather insights from the data provided to generate subject lines most likely to resonate with your audience.

Omnisend’s subject line generator can generate five customized suggestions. To use this feature, you input at least five keywords and a 30-50 character brief describing the content of your intended email.
