Number blocklist

If a recipient has asked you to stop messaging them, add their number to the blocklist.

1. Contacts → Blocklist.
2. Enter the number and, optionally, a reason.
3. Click Add.

Numbers on the list receive neither campaigns nor single messages from you. Each client has their own list: the number will keep receiving messages from other USMS clients.

You can remove a number in the same place — select it and click Delete selected.
