A segment is a saved, reusable filter over your contacts. Build it once — “customers in Kenya”, “signed up this month” — and reuse it across campaigns.

Create a segment

  • Open Segments and choose New segment.
  • Pick which contact lists to draw from (or leave empty to use all of them).
  • Add one or more filters. Each filter is a field, a condition and a value.

What you can filter on

  • Name or phone — e.g. phone starts with +254.
  • Tag — contacts in lists tagged, say, “vip”.
  • Custom fields — any column from your uploaded CSV, like city or plan.

Choose match all to require every filter, or match any to include a contact that meets at least one.

Preview and use

Select Preview audience to see how many contacts match and a sample of them. When you're happy, pick the segment as the audience for a campaign. Find it under Segments in your SMS dashboard.
