Having a phone number or email address is not the same as having promotional permission. A consent record should show who agreed, when, through which source and wording, and for which channel and purpose. Bartago provides operational controls through lead forms, import metadata, contact preferences, and suppression lists; the sender remains responsible for legal basis and policy. Unsubscribe should not merely remove a contact from one list. A global suppression must block future sends within the applicable scope.
Keep consent granular and provable
Channel, purpose, source, and time
Transactional updates, SMS promotions, and email newsletters may require distinct preferences. Do not preselect the checkbox. Save understandable wording, form version, source, and timestamp. Avoid purchased or scraped lists.
Apply suppression before every send
A global guard above list membership
Record opt-out, hard bounce, complaint, and manual do-not-contact reasons separately. Even if an import or automation adds the contact to a list again, the final eligibility check should enforce suppression.
- Consent evidence
- Channel preference
- Global suppression
- Immediate unsubscribe
- Bounce and complaint handling
Minimize data and control access
Collect less and retain intentionally
Do not collect sensitive fields outside the campaign purpose. Define role-based exports, masked analytics, retention schedules, and correction or deletion processes. Justify how long tracking detail remains necessary.
Practical checklist
- Consent wording and version
- Source timestamp
- Channel preference
- Suppression test
- Access roles
- Retention schedule
Key takeaway
The foundation of responsible growth is provable permission and a fast, durable opt-out.
Final thoughts
Audit the current audience and quarantine contacts with unknown consent. Unsubscribe your own address or number and verify suppression across campaigns, automations, and imports. This guide is general information, not legal advice; verify current official requirements.

Can an unsubscribed contact receive promotion from another list?
Not when the promotional scope is global. Define scope by purpose and channel and do not bypass it without valid re-consent.
Why suppress a hard bounce?
Repeatedly sending to an invalid or unreachable address wastes resources and can harm sender reputation; use authenticated provider events.
