Email Validator

What an email format check can and cannot tell you

This tool checks that an address follows the standard structure: one @ sign, a valid local part, a domain with at least one dot and a sensible ending such as .com or .in. It catches typos like missing @ symbols, double dots, spaces and invalid characters before you send a form or an email campaign.

Common mistakes it finds

• name@gmail,com (comma instead of dot)
• name@@gmail.com (double @)
• name@.com or name@gmail (incomplete domain)
• names with spaces or special symbols

Limits to know

A correctly formatted address may still not exist. Only sending a confirmation email proves that a mailbox is real and belongs to the person. Use this validator to clean lists and reduce bounces, but keep double opt-in for sign-ups. Also avoid sending bulk email to purchased lists, since high bounce rates hurt your sender reputation.
