Imagine fundamentally improving service without ever experiencing a single interruption: faster, more reliable, and more scalable. That’s exactly what we’ve just accomplished. Behind the scenes, we completed a full-scale migration of our Transactional Email backend system.

Retarus Transactional Email allows you to define a list of allowed recipient domains. This ensures that messages are only delivered to approved organizations; any emails accidentally sent to domains not part of that list will be dropped.
