Broadcasts
Beautiful emails in your brand, designed by your AI and sent to your whole list.
A/B tests
Test subject lines and versions on every send. The winner goes to everyone else.
Automatic translation
Every customer reads your email in their own language, with no extra work.
Mailboxes that get replies
Replies land in real mailboxes on your domain, and your AI answers them from the same chat.
Signup forms
Popups, bars, slide-ins, or a hosted page: signup forms that add people straight to your lists.
Here’s what happens now.

Banger is free to start: up to 100 emails a day, forever, with unlimited contacts and mailboxes. Paid plans start at $5 a month, billed yearly, and every feature is on every plan.
Which AI apps can run Banger?
ChatGPT, Claude, Grok, Hermes, and OpenClaw. Add Banger to the one you already use, sign in, and start asking. Each has a short setup guide.
Do I need to be technical to set it up?
No. Sign up, connect your AI, and tell it about your business. Banger gives you a working mailbox right away and checks that sending and receiving work. When you add your own domain, your AI gets the exact DNS records to add and verifies them for you.
Will my emails land in the inbox?
Every email goes out on Amazon SES. Banger sets up SPF, DKIM, and DMARC for your domain and handles bounces, complaints, unsubscribes, and suppression, so your sending stays healthy.
Can I see and change what my AI sends?
Yes. Everything your AI builds shows up in the Banger web app, where you and your team can review it, edit it, or pause it. You decide what each agent can access.
Can I use my own domain?
Yes. Create as many mailboxes as you need on your domain, free on every plan. Replies land in those mailboxes, and your AI can answer them from the same chat.
Can I bring my contacts from another tool?
Yes. Import your contacts and your AI maps the fields for you. There is no limit on contacts on any plan.
Is my email content used to train models?
No. Banger does not sell your data or use your email content to train models. Personally identifiable information (PII) is removed before any call to an AI provider.
Is there an API for developers?
Yes. Banger has a REST API, webhooks, and an MCP server, so you can send product email from your own code and connect any MCP client.
