Validation of email addresses allows you to exclude non-existent addresses before you make your first email campaign, which means that the likelihood of getting into the Inbox will increase significantly. We recommend checking databases uploaded to our service for the first time.
If you are confident in the quality of your database, for example, you have recently sent email campaigns via another service, then email validation is optionally.
If you send a campaign with large numbers of non-existent addresses, then for the SPAM filters of the receiving mail service this is one of the most important criteria in order not to accept the mailing in the Inbox.
How much does it cost to check the existence of email addresses?
The cost of validation depends on the size of the email database

|10,000 – 100,000||0.00375 €|
