How can I tell if my text messages are going out?
From the Workflow, click on History to see if the workflow executed correctly.
If this shows as successful, then head over to Salesmsg and search for the contact to see if the contact has been created and any messages have been sent to them.
You can also check the Outbound filter to see any of the messages that were sent from your Workflow.
Can I send text from my Shared Inbox numbers?
Absolutely. From your Workflow, you can select the Shared Inbox phone number and Salesmsg will send the texts from that number.
