Overview
Mailyond is an email service for founders and small teams with many domains. Mail for every address on every domain lands in one inbox, and replies go out from the address the customer wrote to. It also has a Resend-compatible API for sending transactional mail, DNS checks for DKIM, Return-Path and MX, and an MCP server so an agent can read the inbox and reply in the right thread. An agent connected over MCP can send replies from your domains, so decide which actions it may take before you connect it.
