Excluding Segments

Exclude specific segments from your campaign send

Excluding Segments from a Campaign

Segment exclusions let you remove groups of contacts from a campaign's recipient list, even if those contacts belong to your selected target audience. Exclusions are applied at send time and take priority over target audience inclusion.

When to Use Exclusions

  • Recently emailed — exclude contacts who received a campaign within the last 48 hours to avoid over-mailing.
  • Already converted — exclude contacts who already purchased or signed up for the offer you are promoting.
  • Specific customer tiers — exclude VIP customers from a general discount offer.
  • Test holdouts — exclude a control group for measuring campaign lift.

How to Add Exclusion Segments

  1. In the campaign builder, go to the Audience step.
  2. Below the target audience selector, find the Exclude Segments section.
  3. Click Add Exclusion to open the segment selector.
  4. Choose one or more segments to exclude. Segments already selected as target audiences are grayed out and cannot be added as exclusions.
  5. The estimated recipient count updates to reflect the removals.

How Exclusions Are Applied

At send time, Mailnaptic follows this process:

  1. Build the full recipient list from all target lists and segments.
  2. De-duplicate by email address.
  3. Remove any contact who is a member of one or more exclusion segments at that moment.
  4. Apply frequency caps and global suppression.
  5. Queue the remaining contacts for delivery.

Important Notes

  • Exclusions are evaluated at the moment of sending, not when you configure them. Segment membership may change between scheduling and sending.
  • You can view the exclusion segments applied to any campaign on its detail page after sending.
  • There is no limit to the number of exclusion segments you can add to a campaign.

Tips

  • Build reusable exclusion segments (e.g., “Emailed in last 48 hours”) that you can apply consistently across campaigns.
  • Check the recipient count before and after adding exclusions to understand the impact on your audience size.
  • This feature requires the campaign_exclusion_segment database table. If you do not see the exclusion section, ensure the migration has been run.
