Why Should You Validate Email Addresses?

Email verification is a process to ensure the message is delivered to the address the sender wants to send it to. This process works by validating the existence of an email address so that the sent message doesn’t bounce or activate an anti-spam blocking mechanism on the receiver’s end. Some security solutions may not be accustomed to doing so. Hence, the sender can end up on a spam blacklist.

As such, to avoid the hassle that results from being marked as a spammer, you need to validate email addresses. Therefore, any organization that depends on email marketing would do well to integrate an email validator into their existing security solution. This will ensure that they are not only protected from potential threats but also that they won’t end up being seen by recipients as such.

To validate email addresses, we have made the search for the best email verification tools easier. In this article, we have compiled a list of tools you can choose from. These tools can either serve as stand-alone products or integrate into existing email security solutions. That way, users can increase their email deliverability while also staying protected from threats.

There are primarily two types of email checker:

  • API for real-time verification
  • Email list verification in bulk

Generally, API includes most online services. This method gives you the immediate result for the email address you enter. Hence, you will need to integrate API into your website or application for real-time email verification. Using API, you can avoid the wrong or incorrect email addresses from getting into the database.
