SMS Do not contact

Add or import SMS suppression numbers, inspect activity, and manage reviewed release.

Where to find it

Open Do not contact in the SMS workflow.

Address: /account/sms/dnc.

Block numbers

  1. Enter numbers with a leading + and country code, one per line, or upload a one-column CSV. The optional header is phone_number.
  2. Keep the list to at most 500 numbers and the CSV under 32 KB.
  3. Enter List source and Reason so the restriction has a reviewable basis.
  4. Choose Review numbers and correct invalid rows; invalid rows prevent the whole save.
  5. Review the intended count and choose Block N numbers.

Check the masked lookup and recent activity after saving. The restriction applies across the customer's Topline SMS apps and numbers. Messages already handed to the provider cannot be recalled.

Review a release

An authorized reviewer uses Review release, enters the full number and review reason, and confirms the intended removal. Releasing the SMS restriction does not grant consent, override a provider opt-out, or restart canceled messages. Imports, new consent records, and START replies do not automatically clear a Do not contact restriction.

Recovery

Correct malformed or oversized input in the same review flow and retry. Do not interpret a failed lookup as an absent restriction, or re-add the number through another app to bypass it.
