Custom domain email
Feature: AI agents

Your AI agent gets an inbox too

Give Claude, ChatGPT or Grok its own address on your domain, or let it work in yours. It can search, read, reply, forward and file mail, and even set up its own address. You decide what it may do.

  • Connects in a minute through PostPike's MCP server
  • You approve in your browser. The agent never sees a password
  • Mail goes out from your domain, signed and within sending limits
Email for AI agents
No need to move

Keep Google, Microsoft or Zoho, and add PostPike

Happy with your current provider? Keep it. PostPike can add new addresses on the same domain, such as an inbox for your agent or a shared invoices@, without moving anyone's mail.

  • Works with Google Workspace, Microsoft 365 and Zoho Mail
  • A built-in test shows the setup works
  • Move everyone over later, if you like, with mail import

Frequently asked questions

Is PostPike really free?

Yes. The Free plan gives you 1 domain, 5 mailboxes and 5 GB of storage in total, with webmail and IMAP and SMTP for your mail apps. There's no card and no trial period. Webmail on Free may show a small sponsor banner, and mail apps never do. Paid plans, opening soon, add domains, mailboxes, storage, a catch-all address and forwarding to outside addresses.

Do I need my own domain?

Yes. PostPike hosts email on a domain you own, such as yourcompany.com, and doesn't hand out addresses on its own domains. You can buy a domain at any registrar, such as Cloudflare, Namecheap or GoDaddy, and keep it there. You only add a few DNS records.

Can I keep Google Workspace, Microsoft 365 or Zoho?

Yes. Your domain can keep its current provider for your team, while PostPike handles new addresses, such as one for your AI agent. Your provider passes mail for addresses it doesn't know on to PostPike. See how it works.

Which mail apps can I use?

Any app that speaks IMAP and SMTP: Apple Mail on iPhone and Mac, Outlook, the Gmail app, Thunderbird and more. On iPhone and Mac, a setup profile fills everything in. The help center has steps for each app.

How does my AI agent use PostPike?

Through PostPike's MCP server, which Claude, ChatGPT, Grok and your own bots can connect to. You approve the connection in your browser and tick what the agent may do: read, send, organise or set up addresses. It never sees your password. More about AI agents.

Where is my mail stored?

In the EU. PostPike runs on servers in Germany, with full-disk encryption, and mail is encrypted again before it goes into storage. Backups are encrypted and kept in the EU too. More about security.
