Email Validator

This email validator checks whether an address is written correctly and whether its domain can receive mail, without sending anything. Type an address and press Validate. The tool checks the name@domain format, looks up the domain's MX records live, and lists the mail servers in priority order. It flags disposable inbox domains, role addresses such as info@ or support@, and free webmail, and it spots typos like gmial.com with a one-click fix. It also shows whether the domain publishes SPF and DMARC. Switch to List to check up to 100 addresses at once, then download a CSV or copy only the valid ones. It cannot confirm that a specific mailbox exists, because most mail servers will not reveal that.

How to use

01

Enter the email address

Type one address such as name@example.com, or switch to List and paste up to 100, one per line or separated by commas. An address without an @ sign is caught before any lookup runs.

02

Press Validate

The format is checked first. If it passes, the domain's MX records are looked up live, and the address is compared with lists of disposable domains, role names, free providers and common typos.

03

Read the verdict and MX table

Check the Syntax and MX boxes, any typo suggestion or badges, and the summary. In List mode, read the valid, risky and invalid counts, then download the CSV or copy only the valid addresses.

Why Email Validator

What a syntax and MX check can and cannot prove

Validation is a fast first filter. It is honest about what it knows, and it is useful to be clear about where it stops before you delete contacts or blame a customer for a typo.

  • It can prove the address is badly formed, for example a missing dot in the domain or a space in the name.
  • It can prove the domain does not accept email, because there are no MX records or there is a null MX.
  • It can flag well-known disposable domains, role addresses and likely typos of popular providers.
  • It cannot prove the mailbox exists. Only the receiving server knows, and big providers such as Gmail and Outlook do not tell outside checks.
  • It cannot tell whether the address belongs to the person who typed it. Only a confirmation email with a link can do that.
  • It cannot predict spam filtering. A valid address can still reject your message because of your sending domain's reputation or missing SPF and DKIM.

Reading the list results

List mode sorts every address into one of three groups. Use them as a guide for what to keep, what to check by hand and what to drop.

Common questions

How can I check if an email address is valid without sending an email?
Enter it here and press Validate. The tool checks the format and whether the domain has mail servers, which catches typos, made-up domains and throwaway addresses. Nothing is sent, so the owner never knows you checked.
What is the difference between email validation and email verification?
Validation checks what can be proven from the outside: the format and whether the domain accepts mail. Verification goes further and asks the receiving server whether the mailbox exists, usually through an SMTP conversation. This tool does validation only.
Why does a valid email address still bounce?
A correct format and working MX records do not prove the mailbox exists. It may have been deleted, be full, or the server may reject your message as spam. The domain may also accept everything at first and bounce later, which is called catch-all behavior.
What is a disposable email address?
A throwaway inbox from services like Mailinator, 10 Minute Mail or YOPmail, used to sign up without giving a real address. It works for a short time, then disappears. The tool flags domains from a built-in list of well-known providers, but new ones appear all the time, so the list is not complete.
Can I verify that a Gmail address exists with this email checker?
No. The tool can confirm that gmail.com accepts mail, but not that a particular Gmail mailbox exists. Google does not reveal that to outside checks, which is why tools that claim to verify Gmail addresses are often guessing.
How do I clean an email list before a campaign?
Remove addresses with broken formats and domains that have no MX records, drop disposable addresses, fix obvious typos, and decide how to treat role addresses. List mode here checks 100 addresses per run and can copy just the valid ones. For lists in the tens of thousands, use double opt-in going forward and a verification service for the backlog.
Does the email validator catch typos like gmial.com?
Yes, for popular providers. The domain is compared with common ones such as gmail.com, yahoo.com, outlook.com and hotmail.com, and a close miss like gmial.com or gmail.con gets a Did you mean suggestion. One click checks the corrected address. In List mode such addresses are marked risky.
What does the role address badge mean in the email validator?
It marks addresses like info@, sales@ or support@ that belong to a team or function rather than one person. They are real and often valid, but several people or nobody may read them, and some email platforms limit sending to them. It is a warning, not a failure.
What does a Failed MX box mean when I validate an email?
The domain has no usable MX records, so most mail servers will not deliver to it. It also covers a null MX, a record that points at nothing to say the domain accepts no email at all. Check the spelling of the domain first, since a typo is the usual cause.
Does validating an email here send a message to the address?
No. The tool only reads public DNS records for the domain. No email is sent and no connection is made to the mailbox, so the person is never contacted.
