What signups from temp-mail.org mean for you
At registration
A temporary inbox is the cheapest way to open repeat accounts and farm free trials. Checking the address before the account row is written stops it there instead of in a cleanup job later.
After the fact
These inboxes expire, so welcome mail, resets and nurture sequences sent to them go nowhere. Suppress them from mailings and leave them out of your activation and retention numbers.

Frequently asked questions
What is temp-mail.org?
temp-mail.org is a disposable (temporary) email domain operated by Temp-Mail. Addresses on it are short-lived inboxes created to receive a confirmation message rather than to be used as a real mailbox.
Should I block signups from temp-mail.org?
For most products, yes. There is no ordinary reason to register with an inbox that expires, and the account will be unreachable the moment it does. Blocking at the point of registration is cheaper than cleaning up afterwards — see how to block disposable signups in real time.
Is an address at temp-mail.org necessarily invalid?
Not necessarily. A temporary inbox can accept mail right now and disappear a few minutes later. That is why disposable status is reported as its own flag alongside the deliverability verdict rather than folded into it — the address may be deliverable today and worthless tomorrow.
What should I do about existing signups from temp-mail.org?
Export the affected addresses and run them as a bulk check. Suppress them from mailings so bounces do not damage your sender reputation, exclude them from activation and retention metrics, and review any account that shows other risk signals.
Can I check a specific temp-mail.org address for free?
Yes. Use the checker on this page — 5 free checks per day — no signup required. No email sent to the recipient.
