About mxsin

mxsin is an email platform for sending and receiving mail: an HTTP API, an authenticated SMTP relay and inbound delivery to webhooks, with domain authentication and reporting built in.

Who we are

mxsin.com is operated by Interactive Enterprises Limited (company number 137228C).

How we work

• Permission-based senders only. Accounts are reviewed before they can send to external recipients, and our acceptable use and anti-spam policy applies to all sending.
• Email standards. SPF, DKIM and DMARC are configured and checked for every sending domain; our own zone uses DNSSEC, DANE and MTA-STS.
• Abuse handling. Abuse reports are reviewed and acted on, and complaint reports from mailbox-provider feedback loops suppress the recipient automatically.
• Privacy. Servers are located in the European Union, and the website uses no advertising or analytics trackers.
