When we look at Email Validation, this is essentially a procedure that determines whether or not an email address can be reachable or even valid.

Let’s imagine that you are, for example, making great efforts towards collecting email addresses in different ways. You send an important email to the vast contact list. However, you figured out over time that most of the contacts were not valid or correctly formatted. The solution to this issue is email validation. 

If you are curious about what an API is, or what an API key is, you can easily learn about them. Remember to also go over what is SMTP.

The main reasons why you have to validate your email list include:
