🤹‍♂️Contact list domain routing

Contact list domain routing serves two functions in postal route configuration:

Grouping

Logically group domains owned by the same parent company that share a common email infrastructure, such as the merger of Yahoo, AOL, and Verizon.

Isolating

Routing the most important mailbox providers like Gmail through the API, SMTP Relay, or MTA delivery policy where you're getting the best deliverability*.

*Delivery is when a message is successfully delivered, Deliverability is when the message hits the inbox.
