Updated 22 Aug 2026Open Segments in app

A segment is a saved set of conditions that groups matching contacts. You could create one for contacts who opened an email in the last 30 days or for people in the UK with a VIP tag. Membership updates automatically as contact details and activity change, so you do not add contacts to a segment manually.

Build the segment

  1. Open Segments and click New segment

    To start from a ready-made pattern, click Browse templates instead.
  2. Name the segment

    Click the pencil at the top and type into Segment name.
  3. Click Add filter and pick a field

    The fields are organised into four groups. Contact includes email, name, country, status, source, permission and dates. The other groups are Custom fields, Lists and tags and Engagement, which includes opens, clicks, sends, bounces, engagement score and temperature.
  4. Pick the condition and the value

    The available conditions depend on the field type. Text fields include contains and is. Number fields include at least and at most. Date fields use in the last … days. Engagement fields also include options such as at least once and never.
  5. Join the filters

    Choose And when every condition must be met or Or when any one condition can match. If part of the segment needs And while another part needs Or, click Add filter group to create a separate group of conditions.
  6. Check the live preview and click Save

    As you edit, Live preview shows how many contacts match and displays a few examples. Click View all matching contacts to inspect the full list. When you save, MailGraf returns you to Segments.

Use the segment

To use a segment in a campaign, choose Segments on the Audience step and click Add segment. The Segment actions menu for a saved segment includes Create list, Export CSV, Duplicate and Delete. Create list makes a fixed copy of the contacts who match at that moment. The new list does not continue to update with the segment.

The Contacts column on the Segments page shows the last saved count. Click the Refresh count icon in the row to fetch the current number. Campaign sending always calculates the audience from the latest segment rules.

Frequently asked questions

What is the difference between a segment and a list?

You add contacts to and remove them from a list yourself. A segment is a live filter whose membership updates automatically when contact details or activity change.

Why is the contact count on the Segments page out of date?

The column shows the last saved count and refreshes once a day. Click the Refresh count icon in the row to see the current number. Campaign sending always calculates the audience from the latest rules.

Does a list created from a segment keep updating?

No. The list is a fixed copy of the contacts who matched when it was created. Later changes to the segment do not update the list.
