Due to occasional delays with ConnectWise Manage callbacks, we have implemented a fallback using Workflow Rules in order to ensure that messages are delivered to and from you in a prompt manner. In order to enable this feature, go to your Sync Configuration page and check the "Enable Workflow Rules?" checkbox near the bottom and then Save your settings.
Workflow Rules uses emails in order to ensure delivery of messages. Depending on the way that your ConnectWise Manage email connector is configured, this may result in a large amount of emails appearing in "Sent" for your email address.
