One of the best parts of MassMailer Email Verifier is that your emails are quickly verified with a click of a button right within Salesforce. You don’t have to understand the technology behind it or know exactly how it works. But we often have customers who ask about the process that happens behind the scenes each time you verify emails. 

The short answer is, MassMailer Email Verifier tests the validity of an email address, in real time, in 3 simple steps:

  1. Determines if the email address follows the correct syntax and has the physical properties of an email address. Does it have a username and an @ symbol? Is the suffix a recognized email format, such as .com, .org, .net, .edu or .gov, etc?
  2. Verifies the validity of the email domain (MX record) for the email address. This prioritizes the delivery of email messages on behalf of the recipient’s domain to make sure the email domain can send and receive emails.
  3. Connects directly to the email server to authenticate if the email address exists on the server. Instead of a simple ping, MassMailer Email Verifier uses custom integrations developed alongside the ISP to communicate with the server via the preferred method. Our technology works with all global ISPs and is constantly updated for changes in existing ISPs and new ISPs. This method is 97%+ accurate and averages 0.5 seconds per verification.

That's it. Just 3 simple steps, and MassMailer Email Verifier sends you on your way with a cleaner email list. But it's not just one and done. Smart marketers avoid the common trap of only using email verification when a crisis strikes. The most efficient and effective way to keep your email list clean and avoid landing on a blacklist is to use email verification each and every time you send an email marketing campaign.
