Check an email list for typos

| Result | Why | Mail provider |

Typos show as risky with "Fix: [email protected]" in the Why column. The full report CSV has a did_you_mean column with the corrected address.
Why typos matter more than you think
People type their email address fast, often on a phone. A slip like gmial.com means the welcome email, the receipt or the password reset never arrives, and the person thinks you never sent it.
It can be worse than a bounce. Many typo domains are registered by someone else and do accept mail. Then your email, with whatever is in it, lands in a stranger's inbox and never bounces, so you never find out.
Typos it finds
BounceLens compares every domain with the 20 email providers people use and mistype most: Gmail, Yahoo, Hotmail, Outlook.com, iCloud, AOL, Rediffmail, Proton, Zoho, GMX, Yandex and others. Some real examples it catches:
| Typed | Suggested fix |
|---|---|
gmial.com, gamil.com, gmai.com, gnail.com | gmail.com |
gmail.co, gmail.con | gmail.com |
hotmal.com, hotmial.com, hotmail.co | hotmail.com |
yahooo.com, yaho.com, yahoo.co | yahoo.com |
outlok.com, outloo.com | outlook.com |
iclod.com, icloud.co | icloud.com |
rediffmai.com | rediffmail.com |
It suggests a fix when the domain is one letter away from a big provider, or two letters away for longer names. That keeps it careful: real domains like gmx.com or yahoo.co.in are never "corrected".
Other mistakes it catches in the same pass
- Broken format: a missing @, two @ signs, spaces, a dot at the end of the name (
[email protected]), or no extension (jane@company). - Domains that don't exist or have no mail server, including typos of company domains that the provider list can't know about.
- Duplicates, including the same Gmail inbox written differently:
[email protected],[email protected]and[email protected]all go to one person.
How to fix the typos in your list
- Paste the list or upload the CSV above and press Find typos.
- Download the full report (CSV). Every typo has the corrected address in the
did_you_meancolumn. - Don't just swap the address and keep mailing. If you can, ask the person to confirm it (for example on their next login or order). If they signed up for a newsletter, the safest choice is to remove the address: nobody confirmed the corrected one.
Stop typos at the form
The best place to fix a typo is while the person is still on your page. The free Craft CMS and Joomla plugins show "Did you mean [email protected]?" on signup and contact forms. For your own code, the free API returns the suggestion: https://bouncelens.com/api/[email protected].
Questions
Does it catch typos in company domains?
Not as a "did you mean". It can't know that acme-corp.com was meant to be acmecorp.com. But if the mistyped domain doesn't exist or has no mail server, the address is marked invalid.
Can it tell whether the part before the @ is mistyped?
No. [email protected] and [email protected] are both possible addresses. Only a mailbox check with Gmail's server can say whether that inbox exists.
Is there a limit?
No signup and no daily limit. One run checks up to 20,000 addresses.
