AI Writes Your Email Campaigns From Plain English

Brew

Tell Brew what you want in English, and it designs, copies, and builds entire email sequences in seconds—then sends them or ships them to your ESP without lock-in.

Email marketing finally feels like talking to someone who gets it, not fighting software.

The rundown

Email marketing usually means wrestling with templates, tweaking layouts, and hand-coding automations. Brew flips the script: describe your campaign idea like you're chatting with a colleague, and it generates the whole thing—copy, design, audience targeting, and workflow logic—instantly. It's basically Claude for email, so it plays nicely with any AI agent you're already using. You can send straight from Brew or export to Mailchimp, Klaviyo, or wherever you live, so you're never trapped.

What you'd use it for

  1. 1 Launch a Welcome Series in Seconds Describe a 5-email onboarding sequence for new users, and watch Brew build the copy, design, and automation logic without touching a template.
  2. 2 A/B Test Campaigns at Scale Ask Brew to generate two versions of a promotional email with different tones or CTAs, then export both to your existing platform to run side-by-side tests.
  3. 3 Customize Automations Per Segment Paste a JSON list of customer segments into Brew, describe what each group should receive, and it designs personalized workflows for each in one go.

Best for Marketers and growth teams who hate email builders and want to describe campaigns like humans, not click through dialogs.
