Everything you need to know about GenAI in email marketing, and when it’s actually worth your time

You’ve probably asked an AI tool for subject line options and gotten five versions of the same one sentence. Or generated a banner for a sale email that came out looking like every other AI banner floating around this month, soft lighting, a font ghosted into the background. Twenty minutes later, you’re still rewriting the copy it spat out in ten seconds, and it’s fair to ask what exactly got saved.

GenAI in email marketing works best on the tasks that used to eat up your afternoon: first drafts, image variations, routine automations between tools. The judgment calls, tone, strategy, what actually gets sent still belong to you.

This hub is about figuring out where GenAI actually earns its place in your email workflow, and where it still needs you to step in. We’ve also pulled in results from teams already using it inside Stripo, so you’re not just taking our word for it. Read straight through, or skip to whichever chapter matches the problem you’re dealing with right now.
