We handle brand registration, campaign registration, and Campaign Registry fees. Billing starts with an active paid subscription.
$20 / month / active campaign
U.S. carriers require SMS senders to register a brand and 10DLC campaign with The Campaign Registry. On paid plans, managed campaigns are billed only while your campaign is approved and active. Registering your own 10DLC campaign supports higher SMS volume at a lower per-message rate.
