Who hunted Mermail?
Mermail was hunted by Toan Nhu. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.

👋 Hi Product Hunt! I'm Toan, founder of Mermail.
First of all, a huge thank you to our Hunter, the Product Hunt team, and everyone taking the time to check us out today. ❤️
🚀 Why we built Mermail
Over the past year, we've seen AI agents become incredibly capable at reasoning.
But they still struggle with actually getting things done.
They can write code, answer questions, and plan workflows… yet they can't:
* Verify an email account
* Receive an OTP
* Subscribe to a SaaS tool
* Pay for a service
* Manage invoices or billing emails
We realized the missing piece wasn't another model.
It was infrastructure.
💡 Meet Mermail
Mermail gives AI agents what humans already rely on every day:
📧 A real email inbox
💳 A payment layer
🤖 An MCP server that lets agents interact with real-world services
Instead of building custom integrations for every website, developers can simply connect their AI agent to Mermail and let it operate through a trusted identity.
✨ What you can do today
✅ Give your AI agent its own email identity
✅ Receive verification emails & OTPs
✅ Connect with Claude, Codex, and other MCP-compatible agents
✅ Let agents subscribe to products and manage billing
✅ Handle invoices and payment notifications
✅ Prepare for the next generation of agentic commerce
We're also working on Agent Wallet, which will enable AI agents to manage payments even more autonomously.
