How do I segment contacts?

Updated Nov 2, 2026

Segments are built with filters and saved as tags.

Steps

  1. In Contacts, filter by tag, by validation status, or search by email or name.
  2. Select the contacts. To include every match, use Select all … results.
  3. Click Tag Contacts, choose a tag for the segment and click Apply Tag.
  4. Choose that tag when you create the campaign. A contact in any of a campaign's tags is included.

Good to know

  • While a campaign is running, contacts you add later to its tags are emailed automatically.
  • Unsubscribed, suppressed and invalid contacts are skipped even if they have the tag.
