Mailyond lets you send and answer email across all your domains. Mail to any address on any domain you connect lands in one inbox, color tagged by project, and you reply from the address the customer wrote to, in the same thread. No per-inbox or per-mailbox fees: every address on every domain lands in one inbox.
Your app sends from the same domains through a Resend-compatible API: one POST, or point the Resend SDK at https://mailyond.com/api/external and resend.emails.send() keeps working. A hosted MCP server at https://mailyond.com/mcp lets Claude Code, Cursor, Windsurf, VS Code or Grok Bot read and reply across every domain with the same API key.
Connect a domain with three DNS records (DKIM, Return-Path, MX) in about five minutes. Your main inbox doesn't have to move: point a subdomain like hello.yourdomain.com at Mailyond and keep [email protected] where it is.
Pricing: Basic $10/month (5 domains, 5,000 emails), Pro $20/month (10 domains, 10,000 emails, up to 3 members), Agency $40/month (30 domains, 25,000 emails, up to 10 members). 7-day free trial on Basic and Pro.
