Cory Posted September 20, 2023 Report Share Posted September 20, 2023 There are online verifiers. Though you might be then giving addresses to spammers. But they probably have them already. For things like this I often use a class in a programming language. Like if I have a URI I can create an object from string and if it's malformed, I'll get an exception. Also one can doan MX lookup for the domain to validate that portion of it. Send a test email. All validations I've used. Quote Link to comment Share on other sites More sharing options...
