We employ three main steps in our email verification process.
Our system will :
Check 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?
Verify 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.
Connect directly to the email server to authenticate if the email address exists on the server. Instead of a simple ping,Checkr uses custom integrations developed with the ISP to communicate with the server via their 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.
Our system will perform these tests and a few others to make sure that your list stays free of spammy and other invalid email addresses. We recommend that you keep your e,ail lists clean by running your lists through our system before sending out any email campaigns.
