Keep the suppression model minimal and obvious
Start with one canonical suppression field on the contact record (call it "email_suppressed" or "do_not_email"). This single boolean should be the decisive signal your automations and email tool consult before sending. Keep it simple: true = never send, false = eligible (subject to consent checks).
Alongside the canonical flag, record three lightweight fields: consent status (opted-in / not opted-in / unknown), VIP flag (manual protect), and suppression tag(s) for campaign-specific exclusions. The operational precedence you’ll use across systems should be clear: consent → VIP → suppression tags. In practice that means: if consent is not present, block sends; if a VIP flag exists, require manual approval; finally apply any campaign-specific suppression tags.
Implement in 1–3 hours: step-by-step actions
- Create the canonical suppression field in your CRM and the equivalent in your email tool, then make it read/write only for a single owner or integration account. Backfill it from recent unsubscribes, a central unsubscribe list, and your forms.
- Map imports and integrations so they write to the canonical field (not to many different fields). For scheduled CSV imports, add a rule: imports may set suppression true but never clear it unless a human confirms.
- Add a simple automation or segment rule: block all sends unless consent = opted-in AND email_suppressed = false. Add a second rule to pause sends to VIPs for manual review.
Run a dry‑run: export the final eligible list and scan for obvious mistakes (company domains, internal emails, repeat patterns). This testing is quick in HubSpot, Salesforce or any email platform and prevents the common accidental blast.
Common gotchas and quick rollout tips for small teams
- Imports: bulk imports often lack consent data. When importing, require a column that explicitly sets the canonical suppression flag or consent; never flip suppression from true to false via a blind import. Timestamp backfills so you can undo mistakes.
- Two‑way syncs: avoid write-conflicts where an email tool clears CRM suppression on a later sync. Make the suppression/consent fields source-of-truth in one system (CRM usually) and configure the other to respect but not overwrite without a human step.
- Reactivated contacts: treat reactivation as an explicit opt-in action (form submission, verbal consent logged) and record a date. If someone was previously suppressed, do not auto-reactivate them without a recorded consent event.
Quick platform tips: HubSpot — use subscription types plus one custom boolean and gate workflows by that boolean; Salesforce — use Email Opt Out plus a custom suppression field and one validation rule to stop automated clears; plain email platforms — maintain a global suppression list and sync it nightly from your CRM. Keep campaign-specific suppressions as tags or segments, not separate booleans.
Add simple monitoring: a daily count of suppressed contacts, one canary send to a test segment, and a weekly audit of recent changes to consent/suppression fields.
