What signups from 11166666.xyz 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 11166666.xyz?
11166666.xyz appears on the public disposable email domain blocklist maintained by the open-source disposable-email-domains project. Domains on that list hand out temporary inboxes for one-off signups. The operator behind 11166666.xyz is not independently documented here, so it is listed as community-reported rather than attributed to a named provider.
Should I block signups from 11166666.xyz?
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 11166666.xyz 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 11166666.xyz?
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.

Yes. Use the checker on this page — 5 free checks per day — no signup required. No email sent to the recipient.
