Mailyond: Shared Inbox & Email API for All Your Domains
Introduction
One inbox for every domain you own, with reply-as-brand support and a simple email API for sending from your app.
Mailyond's Overview
Mailyond is a shared email inbox and transactional email platform for founders running multiple products and domains. It lets you read and answer mail for all connected domains in one inbox, reply from the same address the message arrived at, and send mail from your app with one API key. Mailyond is designed to replace the common setup of forwarding rules plus a separate sending service, while keeping your main inbox where it already is. It supports DNS setup with DKIM, Return-Path, and MX records, includes an MCP server for AI agents like Claude or Grok Bot, and offers domain-based inbox management with color tagging and workspace controls.
