WHAT IS AN EMAIL VERIFICATION API?

An email verification API, also known as an email validation API, is a means for
developers and product architects to integrate email checking capabilities into
existing software and applications via API calls using different programming
languages.


PRACTICAL USAGE


IMPROVE MARKETING CAMPAIGN RESULTS

In email marketing, it is important that the emails you send are verified,
validated, and received by customers. One of the most common causes of email
bouncing is sending to unverified email addresses.

By eliminating bounced emails and utilizing email verification and email
validation tools, you can increase your sender score and email campaign quality.


ENSURE THAT USERS WHO SIGN UP TO YOUR WEBSITE HAVE A VALID AND VERIFIED EMAIL
ADDRESS

 * You can use our email verification services to check that someone signing up
   to your service is doing so using a business-branded email address.
 * Stay in touch with subscribers and use their verified email addresses to warn
   them of their payment card expiration, send them receipts, offer them new
   features or products, and more.
 * Enables your users to reset their password securely should they forget it.
 * Helps verify someone’s identity automatically without relying on manual human
   checks.




SEGMENT POTENTIALLY DANGEROUS EMAILS

 * Keep potentially unverifiable email addresses such as disposable ones out of
   your contact list. Users signing up for freemium services with disposable
   email addresses may turn out to be abusers.
 * Avoid entanglements with cybercriminals and fraudsters who hide behind fake
   personal or business email addresses.
