Email Validation Vs Email Verification

Email validation and email verification are two processes that are often confused with one another.

Both aim to ensure that an email address exists and has the correct format, but they differ in their methodology and what they can guarantee.

Email validation is a simple process that checks an email address’s syntax to ensure it is correctly formatted.

This type of check can be done programmatically with relative ease. Email validation does not guarantee that the email address exists or is associated with an active mailbox.

While on the other hand, Email verification does guarantee that the email address exists and is associated with an active mailbox.

This is done by sending a test message to the email address in question and then waiting for a response.

If no response comes back after a certain period, the email address is considered invalid. 

Email verification is a more reliable way to ensure an email address is valid, but it is also more time-consuming and difficult to automate.

What is Email Validation Process?

Similarly, email validation is the same as email verification. However, the latter is more complicated than the first one.

So, email address validation improves the efficiency of your email deliverability.

Meanwhile, here are some examples of invalid email addresses:

  • [email protected] ( Consecutive dots [ . ] are not allowed )
  • [email protected] ( Reliable domain name doesn’t start with the dot [ ] )
  • John[]$ ( Remove email addresses that include underscore, dash, and numbers only )
  • ( [ @ ] Symbol must exist )
  • [email protected] ( [ .b ] is not a reliable domain name )
