Validating email address form
Verify an email address in real-time to see whether it's properly formatted, and whether its mailbox exists and can accept new email messages; our free online email validator will immediately generate a detailed report without sending out any emails.
To complete the validation of the address you should re-process the verification within a small delay of time (usually 5-10 minutes), until the server answers with a different message.Ranges can also be combined with character sets (mentioned previously): [a-z A-Z,&*].NOTE: When trying to search for actual instances of any character that has a specific meaning in regular expressions, like ^ and $, you need to "escape" the character in your search query by placing a backslash in front of it. They can get ridiculously convoluted as in the case above and, according to the specification, are often too strict anyway.
If you actually check the Google query I linked above, people have been writing (or trying to write) RFC-compliant regular expressions to parse email addresses for years.To verify the validity of an email address simply enter the email address into the box provided and our "validate email address" tool does the rest.
