We used to use Autotask's built-in email processor, but switched to Email2AT.
With Email2AT, I can create workflows that were not possible before, which allows me to save time.
Support is super helpful. Every question or idea I have come up with, they have had a solution for. Very impressed.
To a friend in the MSP industry, I would say that Email2AT is a must have for any MSP that uses Autotask and wants to save time, reduce duplicate tickets, and create better working workflows.
