Campaign Subscription Management

Action Needed For Vonage Customers Using US Shared Short Codes

Effective immediately, Vonage will no longer accept new programs for Shared Short Codes for A2P messaging. T-Mobile and AT&T’s new code of conduct prohibits the use of shared originators, therefore, existing Shared Short Code traffic must be migrated by March 1, 2021. To help you with this transition, please use the Vonage guide to alternatives. Please contact us to migrate to a new solution.

Messaging activities fall under the regulatory guidelines of several groups, depending on the nation in which you send the messages. For more information see Preapproved US Short Codes compliance requirements

You use the opt-in API to:

Create an opt-out process so a user can unsubscribe to your campaign
Resubscribe a user to you campaign

Listen to the incoming requests and manage your recipient mailing list accordingly.
Send a request.
Check the response.

Unsubscribe to your campaign

Unsubscribe requests for Event Based Alerts are forwarded to the webhook endpoint you set in Dashboard.

To handle unsubscribe requests:

Listen to the incoming unsubscribe requests and manage your recipient mailing list accordingly. Once a recipient number has unsubscribed from your campaign, any outbound SMS to that number will be blocked.

Send a request and see the list of phone numbers that are unsubscribed from your campaign:
