The usage of advanced validation significantly improves the qualityof email address verification. This means that you need to insert a list ofdomains to which you want to apply advanced validation.

– Standard validation uses the standard algorithm for email addressverification.Īdvanced validation is an effective algorithm for multiple domains.In the filter settings, specify those domains you want to checkwith this algorithm. – Select the type you need in “Common Settings/SMTP/Type ofvalidation”. – Atomic Mail Verifier supports two types of validation: standardand advanced. In this way, you can specify optimal operation depending on yourmailing list size and computer features.

This step is only possible if you have port 25 open. Theprogram searches for a domain’s SMTP server, and checks for userexistence. – Email address check: the last step for full verification. If a domaindoes not exist, the email address with that domain also does notexist. – Domain check: all domains are checked for existence.

– Syntax check: email addresses are checked for correspondence tothe RFC registration. There are three pre-set verification steps: Each step can be used separately, or aspart of a single verification.
