This product was not featured by Product Hunt yet. It will not be visible on their landing page and won't be ranked (cannot win product of the day regardless of upvotes).
Mermail helps AI agents do more than chat. It provides the identity, communication, and payment infrastructure they need to interact with real online services. Connect via MCP, Skills, or the CLI to let your agent verify accounts, receive emails, complete checkouts, and manage subscriptions securely.
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.

agent identity + checkout is the missing plumbing imo 👏 how do you handle KYC on that?
I love the idea! It would be great if you can integrate with a financial provider who can give those disposable cards?
Congrats! This may make agents very useful in every day tasks. How do you ensure the agent doesn't do something unintended due to misunderstanding users request? I mean stuff like spending too much money without approval?
