What is a Valid Email Address Format? (Examples + Validation Guide 2025)

You may be getting an invalid email address for several reasons, including typos, fake email addresses, or inactive inboxes.

You can fix an invalid email address by correcting any typos, using an email verification service, or removing the address from your list.

The syntax of a valid email address is "local-part@domain", where the local part is the part before the "@" symbol and the domain part is the part after the "@" symbol.

Email validation is the process of confirming that an email address is valid and deliverable.

You can set up email validation by using an email verification service, implementing a double opt-in approach, or using point-of-capture validation.

You can validate an email address without sending an email by using an email verification service or by manually pinging the email address.
