About this tool
Validate email address syntax in real time for single entries or bulk line-by-line lists. Useful for signup form QA, CSV cleanup, and pre-import checks before sending campaigns. This tool focuses on format validation so you can quickly catch malformed addresses before downstream processing.
Frequently Asked Questions
Does this confirm mailbox existence?
No. It validates syntax format only and does not check whether the mailbox actually exists.
Can I validate a list of emails?
Yes. Paste one address per line to get per-line valid or invalid results.
Why can a valid format still bounce?
Format validity does not guarantee domain MX setup, inbox status, or recipient acceptance rules.
