Just testing the trial version and noticed that DEAR does not print shipping labels directly from courier accounts or get tracking info from them once sent. So will give my feature request for DEAR to integrate with www.postmen.com and www.aftership.com (same company).
Postmen API supports a lot of international couriers (not only the usual suspects UPS, Fedex etc.). Aftership is a popular tracking tool for many couriers.
I believe postmen is free for the time being and will charge 1 cent per label from 2018.
