What it is

Transactional email with a long-standing reputation for getting messages delivered, deliberately separating transactional from bulk traffic so one cannot poison the other.

Who it is for

Anyone for whom a password reset not arriving is a serious problem.

Where it is strongest

Mail that absolutely has to land. The separation of transactional and broadcast streams is the architectural decision that makes the deliverability real rather than claimed.

Where it falls short

Stricter than most about what you may send, and they enforce it — which is the reason it works and also an inconvenience. Fewer features than the all-in-one platforms, and the developer experience feels its age next to newer tools.

Our verdict

Recommended when delivery matters more than features. The strictness is the product; if it annoys you, you probably wanted a marketing tool.
