About Mailyond
Mailyond is a shared inbox and email sending service for founders and small teams who run more than one product. Mail for every address on every connected domain lands in a single color-tagged inbox, and replies go out from the address the customer wrote to, in the same thread.
Each domain needs one DNS setup with three records: DKIM, Return-Path and MX. The same domains can send transactional mail through a Resend-compatible API, so an existing Resend SDK can be pointed at Mailyond with a new key. A main inbox such as Gmail can stay where it is, since a subdomain like support.yourdomain.com can be routed to Mailyond.
Mailyond also runs an MCP server so AI agents can list conversations, read threads, reply in-thread and send email across connected domains using the same API key. Pricing is by number of domains rather than per inbox, with a 7-day free trial.
