How do I fix typos in a list of email addresses?
- Paste addresses one per line, or upload a CSV. The email column is found automatically and every other column is kept. Files can be up to 25 MB.
- Press Find and fix typos. Fixes are grouped by change, such as gmial.com → gmail.com, with how many rows each affects.
- Review the groups. Known typos and formatting fixes are safe; close matches are labelled so you can check them, because a real company domain can sit one letter from a popular one.
- Download the corrected CSV. It adds an original_email column and the reason for each fix, so the change is traceable.
Example
- You enter
- Two addresses:
jane@gmial.comandsam@hotmail.con. - You get
jane@gmial.comis fixed tojane@gmail.comas a known misspelling andsam@hotmail.contosam@hotmail.comas a mistyped .com. Each fix can be accepted or rejected, and the download keeps the original in an original_email column.- Limits
- Runs in your browser with no row cap; an uploaded file can be up to 25 MB.
What does an email typo checker fix, and how sure is each fix?
It fixes three kinds of mistake, and labels each one so you know how sure it is. Known typos come from a curated list of real misspellings of Gmail, Yahoo, Hotmail, Outlook, iCloud, AOL and ProtonMail, such as gmial.com, hotmial.com and yahooo.com, plus endings that aren't top-level domains at all, like .con, .cmo and .comm. Formatting fixes handle how an address was typed or exported: spaces inside it, a leading mailto:, a doubled @ or dot, a comma for a dot, or jane@gmail with no ending.
Close matches are domains one keystroke from a large provider's (two for long names), measured with an edit distance that counts two swapped letters as one slip, the approach the open-source mailcheck library made popular. These are the ones to look at. The tool only suggests close matches towards provider names of five letters or more, because short ones collide with real companies: ge.com is one letter from me.com and aon.com is one from aol.com. It also leaves real country versions alone, so yahoo.de and hotmail.it are never "corrected".
What happens if you send to a misspelled email domain?
Sometimes it bounces, and sometimes a stranger's server accepts it. In our check of 37 common webmail typo domains, 17 couldn't receive mail at all, so mail to them bounces and a verifier flags them. The other 20 could: 13 publish MX records and 7 have an address record that mail can fall back to, which RFC 5321 allows when a domain has no MX. Mail to jane@hotmial.com may be accepted by someone else and never come back to you.
That makes typo fixing a different job from verification. Verification asks whether a mailbox exists; the fixer asks what the person meant to type. Run the fixer first, so the address you verify is the one the person actually owns.
How do I stop misspelled email addresses at signup or checkout?
Add a "Did you mean jane@gmail.com?" prompt where the address is typed, so the person corrects it while they still can. If typos keep appearing in your list, they are coming from a form, and a misspelled email address on an order means the receipt and shipping updates go nowhere. Our typo correction guide has tested code for that prompt. Don't silently auto-correct on the form: some addresses that look like typos are real, and changing someone's address without asking is worse than leaving the typo.
For a list you already have, this page gives you the fixes in bulk with a paper trail. To see every syntax problem rather than just typos, use the bulk syntax checker; for duplicates created when the corrected address was already on the list, run the result through remove duplicate emails.
Typo checker, verifier or find and replace: which catches what?
| This typo checker | Email verifier | Find and replace in Excel | |
|---|---|---|---|
gmial.com when the typo domain accepts mail | Fixed to gmail.com | Can pass, since the domain takes mail | Only if you search for that exact typo |
gmial.com with no mail route | Fixed to gmail.com | Flagged invalid, not fixed | Only if you search for it |
| Tells you what the person meant | Yes, for provider domains | No | No |
| Tells you the mailbox exists | No | Yes | No |
| Keeps the original address | Yes, in original_email | Not applicable | No, overwritten |
In Excel, each typo needs its own pass, e.g. =SUBSTITUTE(A2,"@gmial.com","@gmail.com").
Who uses this tool, and for what?
- SaaS teams
- Run the signup export through the fixer to find users who typed
gmial.comand never got their welcome email, then reach them another way or fix the address after they confirm it. - Marketers
- Clean typo domains out of a newsletter or event list before importing it to your ESP, so mail doesn't go to a stranger's server, then verify the corrected list.
- Sales ops
- Fix hand-typed addresses from trade-show scans and CRM entry in bulk, keeping the original in its own column so the change can be audited later.
- Agencies
- Hand a client back their list with every correction listed by reason, rather than silently changed rows, and dedupe the result with remove duplicate emails.
What can’t this tool tell you?
- It only corrects domains towards the big webmail and ISP providers on its list. A typo in a company domain, like
acme.cmo, is left alone, because the tool has no list of what the company's real domain is. - It can't fix the name before the @.
jnae@gmail.comlooks like any other valid address. - Close matches are a guess. A real, small domain one letter from a provider's can be flagged, which is why they are labelled for review.
- A corrected address is not a verified one. The mailbox may still not exist.
Common questions
- How do I fix misspelled email domains in a list?
- Paste the list or upload the CSV above and press Find and fix typos. Misspellings like gmial.com and endings like .con are corrected, grouped so you can review them, and written to a downloadable CSV with the original address kept in its own column.
- How do I correct a typo in an email address?
- Change the domain to the provider the person meant, then confirm with them if you can. For one address, edit it by hand; for a list, this tool groups every fix so you can accept or reject each one. If you already sent mail to the wrong address, it can't be recalled, so send again to the corrected one.
- Is this an email spelling checker for the message text?
- No. It checks the spelling of email addresses, mainly the domain after the @. To spell-check the body of a message, use the checker built into Gmail, Outlook or your writing tool.
- Can it fix a typo in the name before the @?
- No, apart from formatting slips like spaces or a leading mailto:. A misspelled name such as jnae@gmail.com is a different, valid-looking mailbox, and nothing in the text says it's wrong. Only a mailbox check, or asking the person, can catch that.
- Will it change real domains by mistake?
- Known typos and formatting fixes are safe. Close matches are a guess, which is why they are labelled and can be unticked. The tool only makes close-match suggestions towards provider names of five letters or more, and never changes a real provider name on another country ending, such as yahoo.de.
- Does fixing the typo mean the address is valid?
- No. It means the domain is now spelled like the provider the person probably meant. Whether jane@gmail.com is a real, open mailbox is a separate question that only a mailbox check can answer.
- Why not let email verification catch typos?
- Because many typo domains can receive mail. In our check of 37 common webmail typos, 20 had a mail route, so a message to them can be accepted by someone else's server and never bounce. Verification can't tell you what the person meant to type; a typo fixer can.
- Is my list uploaded anywhere?
- No. The file is read and corrected in your browser with JavaScript. Nothing is sent to our servers, which is also why there is no row limit beyond what your device can hold.

A tidy list can still be full of dead addresses.
Extracting, deduplicating and syntax checks all work on the text of an address. None of them can tell whether the mailbox exists. Only the server that hosts it can answer that, through an SMTP check, and that is what the paid product does.
