About this tool
Type an address and this tool checks its structure: exactly one @ sign, a non-empty local part and domain, a dot in the domain, and a sensible ending, while flagging common typing patterns such as double dots or a domain that starts with a dot. It checks format only, so a well-formed address may still belong to nobody, and it never tests deliverability or mailbox existence.
Frequently asked questions
Does a valid result mean the mailbox exists?
No. This tool only checks the shape of the address; confirming a mailbox would need a message to be sent and answered.
Why flag domains like gmial?
Because they match the shape of a well-known provider with a letter out of place, which is a frequent cause of mail going to the wrong place.
