Case Study: APSIS achieves reliable, high-volume email delivery (500M+ emails/month) with SocketLabs Hurricane MTA

APSIS - Customer Case Study

APSIS, a Sweden‑based global technology company behind the APSIS Pro and APSIS One SaaS platforms, needed a highly reliable email delivery capability to support marketing and transactional messages for thousands of customers. To meet this challenge they partnered with SocketLabs and adopted SocketLabs’ on‑premises Hurricane mail transfer agent (MTA) software to provide scalable, secure, high‑volume delivery.

SocketLabs implemented and customized the Hurricane MTA and provided ongoing engineering and deliverability support, enabling APSIS to dynamically shape traffic by ISP, enforce TLS and DKIM security, and reduce infrastructure costs. As a result of the SocketLabs partnership and custom development work, APSIS now reliably sends more than half a billion emails every month and has sustained improved deliverability and performance for over a decade.
