Banger - Win and keep customers with email automation your AI runs

Hey Product Hunt, Tiago here 👋

Right now, someone just signed up for your product and won't come back. Someone left a full cart. Someone is about to cancel. Big companies pay a whole team to catch moments like these. Most of us don't have the time or the people, so those customers quietly drift away.

Banger helps you win and keep them with email automation your AI runs. Nobody slips through.

Tell your AI once what matters, and it builds the Journeys: a welcome that gets new signups to their first win, a reminder that brings the cart back, and a win-back for the customer on the cancel page. Each one is in your brand and A/B tested, and translated so every customer reads it in their own language. When customers reply, your AI answers from the same chat.

Broadcasts, product emails like receipts and notifications, signup forms, and real mailboxes on your own domain all live in the same place. You can review, edit or pause anything in the web app, and you decide what each agent can access.

Run it from ChatGPT, Claude, Grok, or agents like Hermes and OpenClaw. Developers can connect through the REST API, webhooks and MCP server.

Start free with 100 emails a day, forever, plus unlimited contacts and mailboxes.
For the launch, code PRODUCTHUNT takes 25% off your first year on any paid plan, through October 13.
