Solutions

One email platform. Every way you send and receive.

Developers arrive with a job — give an agent an inbox, put webmail on a domain, turn support@ into tickets. Here's how MailKite does each one, on the same account.

One platform, send + receive

Every solution runs on the same account and quota — receive as clean JSON and send from the same API.

Unlimited domains, free

No per-domain, per-server, or per-inbox tax on any plan — run every product and client from one account.

Built for developers

Signed webhooks, 8 language SDKs, a CLI, an MCP server, and an open-source webmail component.
