Email checker

Why this exists

The sample has 1 valid, 1 role, 1 disposable, and 1 invalid.

The published role names are admin, info, support, contact, sales, marketing, noreply, no-reply, help, billing, accounts, team, press, media, hello, office, staff, webmaster, postmaster, and hostmaster. The disposable domains on this page are only mailinator.com, guerrillamail.com, 10minutemail.com, yopmail.com, tempmail.com, throwaway.email, trashmail.com, sharklasers.com, getnada.com, maildrop.cc, fakeinbox.com, tempinbox.com, dispostable.com, mintemail.com, and mytemp.email. That is not a complete list of temporary mail. The published check calls a local part invalid past 64 characters. The RFC limit is 64 bytes. A character outside ASCII can take more than one byte, so 22 Hangul syllables pass the 64-character check and fail the 64-byte check. Gmail treats dots in the local part, and the text after +, as the same mailbox. This page does not merge them. It does not ask the provider whether the mailbox exists. The sample rows [email protected], [email protected], and [email protected] are examples.

How this page works it out

The sample has 1 valid, 1 role, 1 disposable, and 1 invalid. It does not ask whether the mailbox exists. The list stays in this browser.

There are four statuses: a valid shape, a role address, a disposable domain, and an invalid address. A role is checked before a disposable domain. [email protected] is a role.

A domain is invalid when its first or last character is a hyphen. A hyphen in the middle stays. A Unicode domain is not rewritten to punycode.
