FAQ

What is a disposable email address?

An inbox from a service that creates temporary addresses on demand, often used to grab a free trial or download without giving a real email. Mail to them is usually never read.

How many disposable domains do you detect?

Thousands, from a community-maintained public list (CC0) that is updated constantly, including subdomains of known services.

Is a non-disposable address always real?

No. This checks the domain, not the individual mailbox. Use the email validator to also catch bad syntax, dead domains and role accounts.
