Kaspersky Lab is now an official technology partner for the Certified Senders Alliance (CSA), since June 2015. The CSA whitelist is used in Kaspersky anti-spam products in order to improve the false-positive rate. For users of the Kaspersky anti-spam products, this means that wanted emails arrive in the inbox, while a stronger anti-spam filter takes care of blocking spam.


What this means for MailUp senders: higher deliverability!

The technology partnership between Kaspersky Lab and the CSA benefits all participants of the CSA whitelist: from ISPs to bulk mailers and email marketing service providers (ESPs), including MailUp which is a certified ESP and part of the CSA.

As a MailUp sender, this partnership will have a positive impact on your email deliverability, especially with your email communications that are sent to recipients that use Kaspersky Lab’s anti-spam products. Kaspersky Lab now uses the CSA whitelist to improve its anti-spam filters and test for false positives. This improved efficiency in the Kaspersky Lab anti-spam filters provides higher deliverability for MailUp senders, as a lower percentage of your emails will be incorrectly marketed as spam from the Kaspersky Lab anti-spam filters.
