Real mailboxes, read by the people who run the service — no ticket portal, no chat widget. Pick the address that matches your question and you'll get a faster answer. For product questions, the docs and guides often answer fastest of all.
Product questions, billing, plan changes, and account closing. If something in the docs is wrong or unclear, that counts too — we treat doc bugs like code bugs.
Vulnerability reports and security questions — answered within 24 hours, safe harbor for good-faith research. PGP key at /pgp-key.asc, machine-readable contact at /.well-known/security.txt, full disclosure policy on /security.
Data access, export, correction, and deletion requests — GDPR and otherwise. We respond within 30 days, usually much faster. The full policy is at /privacy.
Questions about the terms, DPA requests, and anything a lawyer asked you to send.
Receiving unwanted signups or mail involving an address on one of our utility domains, or seeing this service abused? Send the address involved and, if you have it, the message with headers. Every inbox here exists only through an authenticated API call — there is no anonymous catch-all — so every report maps to an account and an audit trail. Abuse reports are prioritized over everything else in this list.
Our terms prohibit using MailFixture to create accounts on services the customer doesn't operate or have authorization to test; inboxes are for testing your own product. Background on our shared test domains: why test inboxes get blocked.
