Bulk email typo domain checker: do the mistyped domains on your list accept mail?

In short: Paste email addresses and see the ones with a likely domain typo, the corrected address, and whether the typo domain has a mail server. Limit: Reads the domain, never the mailbox: a corrected address can still be a closed one.

A bulk email typo domain checker finds addresses whose domain looks like a slip, such as gmial.com or hotmial.com, then asks DNS whether that typo domain has a mail server. Paste up to 1,000 domains a run, or 5,000 signed in. Each row gives the corrected address and whether it will bounce or may go unnoticed. It checks the domain, not the mailbox.

Price: this tool is free. Checking a whole email list is from $9/mo, and the first 100 checks are free with Google, no card. Check your list free nowSee pricing

Read in your browser. Only the unique domains, never the mailbox names, are sent for a DNS or registry lookup; no mail is sent. This checks the domain, not the mailbox.

Sample result

jane@gmial.com looks like a typo of gmail.com; the typo domain's DNS says whether it takes mail.

Address
jane@gmial.com
Suggested
jane@gmail.com
Reason
Known misspelling

What this means for you

A typo domain that takes mail won't bounce, so the mistake can go unnoticed.

How do I find mistyped email domains in a list?

  1. Paste email addresses, one per line, or upload a CSV. Addresses are found anywhere in the text.
  2. 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.
  3. Read each row: Typo domain accepts mail, Typo domain has no mail server, or DNS didn't answer, with the suggested domain and address.
  4. Fix the rows you agree with, download the CSV and carry the whole list to the mailbox check.

Example

You enter
Three addresses: jane@gmial.com, tom@hotmial.example (a close match with no mail server) and ana@acme.example (no typo).
You get
jane: Typo domain accepts mail or Typo domain has no mail server, with gmail.com and jane@gmail.com suggested. tom: its own row and fix. ana: left out, no typo. Download the CSV.
Limits
Up to 1,000 unique domains a run without an account and 5,000 when signed in with Google. 100 domains a request; DNS only, typo domains only.

Why check whether the typo domain accepts mail?

Most domain typos have no mail server, so mail to them bounces and you learn about the slip. Some typo domains do accept mail, and 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 the result of an MX lookup on the typo domain, not just the correction.

How does it decide something is a typo?

It matches the domain against a list of known misspellings of the big webmail providers, catches a mistyped .com (gmail.con, gmail.cm) and flags domains one or two letters from a large provider. The same logic backs the email typo corrector; see the common email domain typos list for the entries.

A close match can be a real, different domain, so read the suggestion before you change a row.

What does it not catch?

Typos in the part before the @ look fine to DNS and are not found, and neither are typos at smaller or company domains that aren't one slip from a big provider. A corrected address is still only a guess about the mailbox.

Check the corrected list with the mailbox check, which asks the mail server about each address.

Who uses this tool, and for what?

Marketers
Fix mistyped signups before they bounce or go to the wrong inbox.
Event teams
Clean badge-scan and registration lists full of fat-finger domains.
Sales teams
Correct typos in a purchased or exported list.
Developers
Audit a signup export for domain slips your form didn't catch.

What can’t this tool tell you?

  • Reads the domain, never the mailbox: a corrected address can still be a closed one.
  • Only close matches to large providers and known misspellings are flagged; typos elsewhere aren't found.
  • A close match can be a real company's domain, so read each suggestion.
  • Up to 1,000 unique domains a run without an account, 5,000 signed in.

Common questions

How do I find typos in the domains of an email list?
Paste the list into a bulk email typo domain checker like this one. It matches each domain against known misspellings and close matches, then looks up whether the typo domain takes mail.
Is this bulk email typo domain checker free?
Yes. It is a free tool: up to 1,000 unique domains a run with no account, and up to 5,000 a run when you sign in with Google, with no card.
Why does a typo domain accept mail?
Some misspelled domains are registered and given a mail server, so mail to them is delivered rather than bounced. Fix those first.
Does it tell me whether the corrected address exists?
No. It checks the domain, not the mailbox. The correction is a likely fix, not proof the mailbox exists.
Why does it show only some of my addresses?
Only addresses with a likely domain typo get a row. Everything else is left out of the table.
Does it send an email to test?
No. It reads DNS only for the typo domains.

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.
