Setting up inboxes is really easy, it took under 20 minutes of mostly waiting around to have 30 inboxes warming up in Instantly. They function the same as if you did all of the work yourself, which would take hours at minimum. The monthly cost is about half of Workspace, and would drop even lower if using more inboxes.

It's dumbed down even for the most tech retarded person :)

Instead of working 2-3 days trying to add 9 inboxs to Instantly, it took 30 minutes to get 50 inboxes warming up, and ready to blast. Cheaper than Google workspaces and no need to chase after invocies on 5 different email accounts. This is awesome.
