CM Group, the organization behind email-centric services like Campaign Monitor and Emma, today announced that it has acquired marketing automation firm Sailthru and the email personalization service Liveclicker. The group did not disclose the acquisition price but noted that the acquisition would bring in about $60 million in additional revenue and 540 new customers, including Bloomberg and Samsung. Both of these acquisitions quietly closed in 2018.

Compared to Sailthru, which had raised a total of about $250 million in venture funding before the acquisition, Liveclicker is a relatively small company that was bootstrapped and never raised any outside funding. Still, Liveclicker managed to attract customers like AT&T, Quicken Loans and TJX Companies by offering them the ability to personalize their email messages and tailor them to their customers.
