Are your emails reaching their intended audiences? If not, you may only be wasting money with your email marketing efforts. Tools such as emailverification.whoisxmlapi.com can help ensure that your emails serve their purpose—get to your recipients' mailbox and persuade them to convert. An email validator API improves marketing in three ways, but first, let's briefly discuss what email validation is.

What Is Email Validation?

Email validation or verification is the process of ensuring that email addresses exist, are valid, and can receive messages. While this can be done manually, an email validation API and other verification tools can make the process easier and more accurate. Email validator APIs typically can:

  • Check for typos and common misspellings
  • Detect disposable email addresses
  • Ensure that email addresses meet the syntax requirements of the Internet Engineering Task Force (IETF), that is, they should be in the format local-part@domain
  • Check if email addresses have corresponding mailboxes and mail exchanger (MX) records

How Can Email Validation API Help Marketers?

Integrating an email validator API into the customer signup process ensures that the email addresses you send marketing content to receive messages. Therefore, such tools can help reduce hard bounces. In particular, marketers can benefit from an email validation API in three ways.

Improve Email Deliverability

Email deliverability is among the most critical metrics in email marketing. It is the ability to deliver emails to subscribers' inboxes, which several factors can affect. For one, if the email address is invalid or does not exist, that results in a hard bounce.

Consider a potential customer who misspelled his/her email address during the mailing list subscription process. Instead of myname@gmail[.]com, the address recorded in your mailing list is myname@gmall[.]com. Left unchecked, marketing emails sent to this and other misspelled or invalid email addresses would result in hard bounces.

However, an email validation API would alert the potential customer that the email address he/she typed in is not valid.

The email verification tool checks if the email address has a corresponding mailbox and domain. The email address myname@gmall[.]com failed in both checks.

Avoid Spam Traps

Another major factor that affects email deliverability is when Internet service providers (ISPs) and email service providers tag your messages as spam. ISPs create email addresses that serve as spam traps to determine which marketers send messages to people without their consent.

Having even a single spam trap email address on your distribution list could be detrimental to your email deliverability and sender reputation. The ISP that owns the spam trap could categorize all your emails as spam in no time, or worse, your email service provider could suspend your sending capability.

As such, it is vital to regularly clean your mailing list to ensure that it does not contain spam traps. And since spam traps look like any other email address, email validation API can help detect them by conducting a Simple Mail Transfer Protocol (SMTP) check. Spam traps typically don't have SMTP connections since they are not designed to send emails. They also don't have MX records, so they would fail when the email validator API checks for MX record existence.

Increase ROIs

Done right, email marketing could yield one of the highest returns on investment (ROIs) among other marketing channels. A good rule of thumb is: The more people reached, the higher the chances of conversion. And by ensuring that email addresses are valid and existing, your marketing content is delivered to intended audiences.

Aside from improving email deliverability, an email validation API also ensures that marketing content is delivered to the correct audience (i.e., those who are more likely to convert). People who use disposable or temporary email domains are less likely to open marketing emails. As such, an email validator API also checks if an email address was created using one of the thousands disposable email address providers.

Marketers face fierce competition everywhere, which is why it's always a good idea to employ tools that make their jobs easier and more effective. Email Verification API can augment email marketing strategies in several ways. It can reduce hard bounces while avoiding spam traps. The results? Improved email deliverability and better ROIs.
