A segment is a saved subset of your contact list, defined by rules you choose: language, last open date, city, custom fields, purchase history, anything you can express as a filter. Segments let you stop blasting the same email to everyone and start sending the right message to the right people — the single biggest lever for engagement and revenue from email.
Create a segment in 5 steps
1. Open Lists → Segments in your Mailpro dashboard. 2. Click New segment. 3. Pick the source list (or several lists). 4. Add filter rules with the visual builder — combine them with AND/OR logic. 5. Save with a clear name (e.g. «EN subscribers active in 30 days»).
The most useful segment types
| Segment | Filter logic | Use case |
|---|---|---|
| Engaged subscribers | Opened OR clicked in the last 30 days | Send the high-value campaign |
| Re-engagement | Did NOT open in the last 60–90 days | Win-back series before suppression |
| Language / region | Custom field language = X | Localized content |
| VIP customers | Total purchase > threshold | Exclusive offers, early access |
| Cart abandoners | Custom field cart_value > 0 last 7 days | Recovery sequence |
| New subscribers | Subscribed in the last 7 days | Welcome series |
| Geographic | City IN list | Local events, store openings |
How segment rules combine
Mailpro lets you nest AND/OR groups, so a segment can be: (language = EN) AND ((last_open < 30 days) OR (purchase_total > 100)). The visual builder shows the nesting clearly and previews the resulting count in real time.
Sending to a segment
From any campaign, in the Recipients step, choose «Send to segment» instead of «Send to list». Mailpro counts the matching contacts in real time so you see the exact reach before scheduling.
Measuring segment performance
The campaign report breaks down opens, clicks and conversions per segment. After 3–4 sends you see which segments deliver the best ROI and which need redefinition. See measuring segmentation.
Send the right message to the right people
