Understanding CLX's Routing Classes
We have a range of routing classes that you can use depending on what sort of traffic you are sending. Primarily, we have Select and Global – no matter your sending requirements, one of our routing classes will be able to meet and exceed your expectations.
Select (also known as GW6)
Direct routing has the lowest latency and the most stable routing with secure end-to-end delivery. It consists of all our Tier 1 direct connections.
Global (also known as GW0)
Global routing is a curated routing class using carefully selected partners. It balances high quality message delivery whilst maximizing reach.
