Postmark, an email delivery service, has been acquired by ActiveCampaign, a marketing automation and CRM platform. The acquisition aims to enhance Postmark's deliverability and security features while maintaining its independence as a standalone product with the support of ActiveCampaign. The entire Postmark team will join ActiveCampaign, ensuring minimal disruption in services. DMARC Digests, another service offered by Postmark, will continue as a standalone product, with potential integration into ActiveCampaign's platform. Deliverability remains a top priority for both companies, and the acquisition is expected to improve Postmark's infrastructure and resources. The team behind Postmark will work closely with ActiveCampaign to add Postmark functionality to their platform, while maintaining the company's culture and values.
