Suppression lists

The suppression list is your workspace's do-not-contact memory. Once a number is on it, Landing Zone stops texting and calling it — regardless of which list, batch, or campaign the number appears in later.

Why entries are added#

Each suppression entry records a reason:

• STOP — the contact opted out by keyword or free-form revocation; see Opt-outs and STOP keywords.
• Complaint — the contact complained about your outreach.
• Admin — someone on your team added the entry manually.
• Internal DNC — your own do-not-contact designation.
• National DNC (imported) — the number appeared in national do-not-call data you imported; see DNC screening.
• Litigator — the number matched a known-litigator list; see Known-litigator screening.

How suppression is enforced#

Suppression is enforced for SMS and calls. Suppressed numbers are filtered out of batch and campaign SMS eligibility, and click-to-call checks the list before a call connects. Email opt-outs are handled through the email channel's own unsubscribe tracking — the two mechanisms are separate and are not interchangeable.

Adding entries manually#

You can add numbers yourself from Settings → Blocklist — for example, when someone asks you to stop contacting them during a call or in person. Manual entries are recorded with an admin reason.

Suppression outlasts the contact record#

Deleting a contact does not remove the suppression entry for their number. If the same number comes back in a future import or skip trace, it stays suppressed. This is deliberate: a person's request to be left alone should not be erased by list churn.

What suppression does not do#

Suppression is permanent protection for the people on the list — not a compliance guarantee for everyone off it. A number's absence from the list is not evidence of consent, permission, or lawfulness; it only means none of the reasons above have been recorded in your workspace. You still own the decision to contact every number that passes, as described in User responsibilities.
