How to Find Typo Domains Like gmial.com in an Email List
To find typo domains like gmial.com in an email list, match each domain against known misspellings of the big webmail providers, then check whether the typo domain takes mail. The bulk email typo domain checker does both for a pasted list or CSV, up to 1,000 unique domains a run (5,000 after a free Google sign-in), and gives the corrected address for each hit.
It checks the domain, not the mailbox. A corrected address is still only a likely fix.
Why the typo domain matters more than the typo
Most misspelled domains have no mail server, so mail to them bounces and you learn about the slip. Some typo domains do accept mail. There nothing bounces: the message goes to whoever runs that domain. Those are the ones to fix first, because the error is silent. That is why each row carries an MX lookup on the typo domain.
The by-hand way
Sort the list by domain and read the short ones that look like Gmail, Hotmail, Yahoo or Outlook, then check each odd domain with the MX lookup. The common email domain typos list shows the usual entries. For catching slips at signup instead, see email typo correction.
Step 1: paste the addresses
Paste addresses one per line, or upload a CSV. Addresses are found anywhere in the text.
Step 2: run the check
Press Find typo domains. Domains are matched to the typo list in your browser and only the typo domains are sent for an MX lookup. No mail is sent.
Step 3: read the result
| Result | What it means |
|---|---|
| Typo domain accepts mail | The slip is silent. Mail goes to someone else. Fix first |
| Typo domain has no mail server | Mail will bounce. Fix or remove |
| DNS didn't answer | A timeout. Run the list again |
Each row shows the suggested domain and the corrected address. Fix the rows you agree with. A close match can be a real, different domain, so read the suggestion before changing a row. The same logic backs the email typo corrector.
What this check cannot do
- Typos before the @ are not found.
- Typos at smaller or company domains that are not one slip from a big provider are not found.
- It matches known misspellings, mistyped .com endings (gmail.con, gmail.cm) and domains one or two letters from a large provider.
- The limit is 1,000 unique domains a run without an account and 5,000 signed in.
What to do after this
After the fixes, a corrected address is a guess about the mailbox. That is what the verify page is for, with 100 free checks after a Google sign-in. Results are valid, risky or invalid, each with a reason, and the people on your list are never contacted. Pricing lists the options for bigger files.

Common questions
How do I find typos in the domains of an email list?
Match each domain against known misspellings of the big webmail providers and flag close matches. A bulk email typo domain checker does this for a pasted list and suggests the corrected address.
Why would a typo domain accept mail?
Some misspelled domains are registered and given a mail server, so mail is delivered to whoever runs them rather than bouncing. Fix those first.
Does the corrected address exist?
Not necessarily. The check reads the domain, not the mailbox. The correction is a likely fix, not proof.
Why do only some of my addresses appear in the results?
Only addresses with a likely domain typo get a row. Everything else is left out of the table.
Does it catch typos before the @?
No. A typo in the name part looks fine to DNS and is not found.
