Email Syntax Validator
Check whether an email address is correctly formatted and catch common typos before they bounce.
Why syntax matters
A correctly formatted address is the first requirement for delivery. Syntax validation catches missing @ signs, bad characters and malformed domains, but it cannot confirm the mailbox actually exists. A well-formed address on a dead domain still bounces.
For a full check including the mailbox, MX records and SPF, DKIM and DMARC, use the free email checker, or read how to check if an email is valid.
