Instantly check whether an email address is validly formatted and whether its domain can receive mail. Free — your addresses stay in your browser.
Paste the addresses
Enter one email address, or a whole list, one per line.
Run the check
Each address is validated for correct syntax and common typos.
Check the domain
Optionally confirm the domain has a mail server that can receive email.
Verify for real
Run a full deliverability check before you send to the list.
Sending to malformed or mistyped addresses bounces, and a high bounce rate quietly wrecks your sender reputation — pushing even your good emails into spam.
This free email checker catches the obvious problems first: bad syntax, missing domains, consecutive dots, and the classic typos like gmial.com. It can also confirm the domain actually has a mail server, right from your browser.
A perfectly formatted address can still be dead — the mailbox may not exist, or it may be a catch-all that accepts everything and tells you nothing.
When you need certainty, Emailchaser's free email verifier performs a full deliverability check on each address so you only send to inboxes that are real.
How do I check if an email address is valid?
Paste one or more addresses above and the checker instantly confirms whether each is correctly formatted, flags common typos (like gmial.com), and — optionally — checks whether the domain has a mail server that can receive email. For a full deliverability check, verify the address too.
What's the difference between a valid format and a real email?
A valid format just means the address is written correctly (name@domain.com with allowed characters). A real email is one that actually exists and can receive mail. This tool checks the format and whether the domain accepts mail; an email verifier confirms the mailbox itself exists.
Does this checker detect email typos?
Yes. It catches missing @ symbols, spaces, missing domain extensions, consecutive dots and common provider misspellings such as gmial.com, hotmial.com and yaho.com — and suggests the correct address.
Is the email checker free?
Yes — it's free, needs no signup, and the syntax check runs entirely in your browser. The optional mail-server (MX) check uses a public DNS lookup; your addresses are never stored.
