Clean Your Mailing List.


Remove Bounces, Invalids, Spamtraps Emails


Why work with us?

We have an advanced system of cleaning, with high success rate, performing all the validations made by any web similar to ours, but as we do not dedicate effort in web design and very elaborate reports, we can offer much more competitive prices.

Our system of cleaning and validation of emails uses the following systems:

  • advanced syntax verification, according to the Internet IETF standards;
  • international domain names (IDN) and international mailboxes check, built to handle non-ASCII email addresses with non-Latin symbols and alphabets;
  • ISP-specific syntax validation, with support for dozens of the biggest ISPs;
  • DNS validation, including MX record(s) lookup;
  • disposable e-mail address (DEA) validation;
  • SMTP connection and availability checking;
  • mailbox existence checking, with greylisting and temporary unavailability support;
  • catch-all testing.
  • Spamtraps database with more than 5,000,000 records for check.
