Segments let you define an audience once and reuse it across every campaign and poll you send. Instead of rebuilding the same filter combination each time, you save it as a named segment and select it at send time. Your segments also stay current automatically—when contacts are added or updated, Amplifi recalculates who qualifies.

​
Segments vs. tags vs. filters

These three tools work differently, and using the right one for the right job matters:
TagsSegmentsFilters

Persists?Yes, on the contact recordYes, as a named audienceNo, discarded after use
Based onManual assignment or importFilter logic you defineFilter logic applied once

A common pattern: apply tags during import to mark list origin, then build a segment that combines those tags with additional rules like textability or geography.

​
The default “Textable” segment

Amplifi automatically maintains a segment called Textable. It includes every contact who is verified textable and not opted out. If you’re not sure which segment to use when setting up a campaign, starting with Textable ensures your message only goes to people who can receive it.
The Textable segment is managed by Amplifi and cannot be deleted. You can use it as a starting point for custom segments by referencing similar filter logic in a segment you create yourself.

​
Creating a segment

1

Open the Segments panel

From the Contacts area, find the Segments section. Select the option to create a new segment.
2

Name your segment

Give it a clear, descriptive name—something that communicates who’s in it, such as “NYC donors” or “Verified textable, tagged event-2026.”
3

Add filters

Build your audience by combining one or more filters. You can add as many conditions as you need. See the full filter reference below.
4

Preview the count

Before saving, Amplifi shows an approximate count of how many contacts currently match your filters. Use this to confirm your targeting looks right.
5

Save the segment

Save the segment. It’s now available to select when composing a campaign or setting up a poll.

​
Filter options

Segments support a broad set of filter conditions:
Include contacts who have one or more specific tags. You can require all tags to match or any one of them.
Filter by verified textable, non-textable, or unknown textability status.
Include or exclude contacts who have opted out.
Filter for contacts who have a phone number on file, an email on file, or neither.
Target contacts in a specific geographic area. You can combine multiple states or ZIP codes.
Filter on any custom field your organization has created—whether it stores text, a number, or a date.
Target contacts added or modified within a specific date window. Useful for reaching new imports or recently updated records.
Filter by how recently a contact last received a message from your organization. Useful for re-engagement targeting or suppressing people you’ve contacted recently.
Include only contacts your team has manually starred.
Target contacts who have replied to at least one message—a useful signal for engagement-based follow-up.
Include contacts added during a specific import batch. Lets you target an entire list by its import name without needing to tag everyone individually.
Filter by name, phone, or other text-based fields for keyword-based matching.

​
Editing a segment

Open any saved segment and update its filters at any time. The change applies the next time the segment’s count is calculated or the segment is used in a campaign or poll. Editing a segment does not affect campaigns that have already been sent.

​
Using segments in campaigns and polls

When you compose a campaign or set up a poll, you choose your audience during the targeting step. Select Saved segment and pick the segment you want to reach. Amplifi shows you targeting stats—total matching contacts, SMS-eligible contacts, non-textable contacts, and contacts with unknown textability—so you can confirm the audience size before sending.
If you need to target a slightly different audience for a single send, you can use an ad hoc filter instead of creating a permanent segment. Ad hoc filters are applied at send time and not saved.
Campaign and poll targeting stats refresh when you make your audience selection. If you’ve imported new contacts recently, the counts will reflect those additions.
