Website overview
About Groundmail
Groundmail sends the mail a user is waiting on: sign-in codes, password resets, receipts and alerts. Use the HTTP API, an SMTP relay, SDKs for Node, Python, Go, PHP, Ruby and Rust, a CLI or an MCP server. Replies come back to your app by webhook, and AI agents can have real mailboxes they read and reply from. Templates, automations and a test inbox are included. Transactional, product and newsletter mail each send from their own IPs, and cold email and purchased lists are never allowed. Median time from API accept to the recipient's mail server is published hourly at groundmail.dev/proof.
