Most “autonomous” AI agents are one verification email away from becoming useless.

They can research, browse, and write code.

Then a website says:

“Check your inbox.”

Or:

“Enter your payment details.”

Suddenly, the autonomous agent needs a human again.

That’s why we built Mermail, launching today on Product Hunt.

Mermail gives AI agents the identity, communication, and payment infrastructure they need to interact with real online services.

Connect it through MCP, Skills, or the CLI, and your agent can:

• Sign up for online services

• Receive verification emails

• Confirm accounts

• Complete checkouts

• Manage subscriptions and receipts

• Keep the entire workflow moving without handing every small step back to you

All while access and control stay on your side.

We’re not building another AI that helps you write emails.

We’re giving your existing AI agents the missing infrastructure to actually finish the job.

Your AI can now sign up and pay.

We’re live today, with the first month of Pro available for $1.

Check out Mermail and tell us honestly: what’s the first online task you would let your agent complete from signup to payment?
