The Top 40+ AI Tools Being Used to Scale eCommerce Email
The Top 40+ AI Tools Being Used to Scale eCommerce Email
Our team here at FlowCandy has invested serious time into auditing winning email campaigns and flows that brands and businesses use to capture revenue.
This has given our team an inside look at the AI tools that are giving brands an edge in their email marketing.
Which tools deliver what they promise?
What programs need more work to generate a beneficial output?
Are some AI programs not worth the time or money?
We decided to find the answers to those questions. Some brands utilize AI tools to their advantage, saving time and reducing costs. Other brands sometimes invest too much time in a tool that isn’t showing a benefit.
This guide breaks down six tools in each category of email marketing so you know which to start implementing into your own stack.
We based the stack on real usage across growing eCommerce brands.
Most in-house teams fall into two different categories when it comes to their email marketing systems. Neither is right or wrong.
The first group is operating with manual testing and not prioritizing AI tools. They might dabble and try a program out, but they’re not using AI as a way to speed up their process.
The other group uses AI to make their email marketing more efficient by being able to test copy a bit quicker and analyze data in a more systemized way.
Here are the 40+ tools we’ve seen these brands use to integrate AI to scale their email marketing systems, followed by a more in-depth breakdown for each tool.
