Checks the domain against common mailbox providers and flags likely misspellings. Runs entirely in your browser.
Why a mistyped domain is a guaranteed bounce
A typo in the domain is one of the most common, and most preventable, causes of a hard bounce. Someone means to type gmail.com and fat-fingers gmial.com; the address is valid in form, so it sails past a format check and into your list, where it sits until your next send hard-bounces it. And a mistyped domain isn't just a bounce - it can be a spam trap, since some operators register typo domains specifically to catch careless senders.
Caught at signup, it's a save
A did-you-mean prompt turns a lost subscriber into a corrected one in a single click - far better than a silent bounce weeks later.
It's the one check regex can't do
A pattern can't tell a real domain from a near-miss of one - that needs a comparison against known providers. More in why regex email validation fails.
Email typo checker FAQ
Most often it's a misspelled domain - gmial.com for gmail.com, hotnail.com for hotmail.com, yaho.com for yahoo.com. The address is perfectly valid in form, so a basic format check waves it through, but it points at a domain that either doesn't exist or belongs to someone else. Either way, mail to it bounces.
It compares the domain against a list of common mailbox providers using edit distance - the number of single-character changes needed to turn one string into another. A domain that's exactly one insertion, deletion, substitution, or transposition away from a known provider (like gmial → gmail) is flagged with a suggested correction.
Because a regex checks the shape of an address, not whether the domain is real or intended. gmial.com is a syntactically perfect address - a regex sees nothing wrong with it. Catching the typo needs a comparison against known good domains, which is a different kind of check. See our guide on why regex email validation fails.
Suggest, don't silently correct - the best place is a did-you-mean prompt at signup, so the person confirms the fix themselves. Auto-correcting risks changing an address the user actually meant. A one-click 'did you mean gmail.com?' saves the subscriber without guessing on their behalf.
No - it catches misspellings of well-known providers, which are a big and preventable source of hard bounces. It won't catch a typo of an obscure domain, or an address that's spelled correctly but doesn't exist. Full verification confirms the mailbox itself; this tool catches the fat-finger errors first.
