If you regularly send mass texts from the Messages page, you might find it helpful to see specific details for each subscriber that was sent your message. The Message Activity Table lets you do exactly that. Quickly see if your message had any failures, or opt outs. You can also see each person's wireless carrier and the phone number your text was sent from.

To view this table, click on the Messages tab on the left-hand side, select a message from your sent messages, and then scroll down.

If anyone opted out of your account after receiving your text, you can view your "Opt-outs", see details of how they opted out, and when.
