It is our biggest concern to only provide you with the highest contact quality. We delete non functional data immediately. If you ever feel that data is not accurate don't hesitate to contact us at [email protected] and we will resolve the problem. All together, your point of view is, to filter in our already cleaned datapool and then hit "Verify all selected contacts" for max. data accuracy.

The email verification process

Leads.cm completes a comprehensive email verification process to provide our users with the highest email verification accuracy possible.

  • Email syntax check → we check if emails contains allowed characters only, a prefix, an @ sign, and a domain.
  • Domain check → we check if the email domain exists and has published DNS required to accept emails - this already makes the data 92% accurate.
  • SMTP test → we regular connect to the email server of the email address and ask the recipient server if the email address exists.
  • Free detection → we check if the email domain is a known free email service provider, such as Gmail.
