Free Email Verifier - Check If an Email Address Is Real
You collect email addresses everywhere: signups, orders, lead magnets. Some are fake, some are temporary, some belong to a mailbox that no longer exists. An email checker (also called an email verifier) tells you whether an address is real and can actually receive mail. Paste one in below to check it before you send. No signup needed. Fewer bounces, a healthier sender reputation.
Checking email…
- Syntax validation
- Role address check
- DNS & MX lookup
- Disposable database match
- SMTP mailbox verification
What is Emails Checker?
- First, it checks that the email address format conforms to IETF/RFC standards.
- Then it makes sure the domain name is valid: not a disposable email domain, and with a valid DNS record.
- In the final step, it fetches the MX records from the domain and connects to the mail server (via SMTP, simulating message delivery) to confirm the mailbox actually exists.
Key email verification features.
Everything you need to check addresses, clean your lists, and keep bad emails out of your campaigns.
Validation & Verification
A 9-step algorithm determines whether each email address is valid or invalid.
Email provider database
1M+ blacklisted and disposable domains on file, so bad and temporary domains get removed from your email list. The list keeps growing as new temporary email services show up.
Accept-all email detection
We flag addresses on accept-all mail servers so you can judge the risk before sending to them.
Email verification API
Verify emails directly from your own platform and remove bad addresses from your mailing list automatically.
B2B leads finder
Find valid business email addresses using just a domain and a person's name.
Real tech support
Questions get answered through chat and email. Developers can get help directly in chat instead of waiting on tickets.
Email verification for every workflow.
Check one address, clean a whole list, or plug verification straight into your app. Our disposable domain database and mail server checks keep pace as providers change, so today's result still means something tomorrow.
Bulk email checker.
Upload a list of email addresses in any common format with bulk email verification. The 9-step algorithm checks every address, and large lists finish within hours. Download the verified list and export only the addresses you want to send to.
- Fewer bounces: bad emails are removed from your lists.
- Invalid addresses are gone before you hit send.
B2B leads finder.
Give it a first name, last name, and domain name, and the tool works out likely email addresses for that person, then validates them. The B2B leads finder automates lead hunting: no more creating and testing address guesses one by one.
- Create and validate 34 possible different emails per person.
- Less manual work to find valid lead email addresses.
Realtime multi-platform API.
Integrate with a simple REST API to verify emails, manage lists, and more. Requests are rate limited to 60 per minute by default, but you can turn the limit off in your settings page. Free plan users get access too: 100 credits for testing, enough to try the API before you commit to a paid plan. Already have an email marketing setup? Connect it through the same API. See the full documentation and code samples for every major platform.
