Will email sent to a mytemp.email address be delivered?

Often yes, right now — and that is the trap. While the inbox is live the mail server accepts messages normally, so the address verifies as deliverable on any tool that only checks DNS and the mailbox. It stops being read once the session-based window closes, so the delivery is real and the relationship is not.

Should I block signups from mytemp.email?

For a paid product or a free trial, yes — a throwaway address is the standard way to farm repeat trials and there is no way to reach that user again. For a content signup it is a judgement call, since some people use throwaways for legitimate privacy reasons. A middle path is to accept the signup but require a confirmed permanent address before granting anything valuable.

About MyTemp.email

Generic throwaway on a descriptive domain. Included here because the name is close enough to legitimate services to slip past manual review.

Other domains from the same provider

Disposable services deliberately run many domains, so a blocklist containing only the brand name catches a fraction of the traffic. These are 2 more domains on our list that appear to belong to MyTemp.email:

mytempemail.com
mytempmail.com

Why it verifies as deliverable anyway

While the inbox is live, mytemp.email behaves like any ordinary mail host. It has valid MX records, it accepts mail, and the mailbox exists. A verifier that checks syntax, DNS and the mailbox will report the address as valid — correctly, on the evidence available.

That is why disposable detection has to be a separate check against a maintained list, and why the size of that list is the whole product. Nothing in the address or the SMTP conversation reveals that the mailbox is about to be discarded.
