What's the difference between the Message Delivery & the Credit Usage reports?
The Message Delivery report shows the numbers of text blasts sent and how many messages were sent for each of those text blasts. The report also shows how many credits were used to send those messages.
The Credit Usage report shows all the credits you've used including messages sent, opt-in messages, opt-out messages, mobile coupons, etc.
To summarize, the Messages Sent report shows text messages sent from text blasts and the Credits Used report shows everything that requires credits to be used including messages sent.
Have a great week!
