Segments Overview

Segments let you group subscribers based on their attributes and behavior. Use segments to send targeted notifications to specific audiences.

Why Use Segments?

Instead of sending to everyone, segments let you:

• Target specific user groups
• Increase relevance and engagement
• Reduce unsubscribes
• Personalize messaging

Example segments:

• "Mobile users in the US"
• "Users who clicked in the last 7 days"
• "Premium plan subscribers"

Accessing Segments

1. Navigate to your app
2. Click Segments in the app menu

Segment List

View all your segments as cards showing:

• Segment name
• Description (if provided)
• Number of matching subscribers
• Last calculated timestamp

Actions

Action	Description
Create	Add a new segment
Edit	Modify segment rules
Recalculate	Update subscriber count
Delete	Remove the segment

Segment Templates

For common targeting needs, you can skip manual rule-building entirely. Templates create the segment with one click — you can rename it or adjust the rules afterward before saving.

Template	Rule(s)
Highly Engaged	Clicked 3+ notifications and seen in the last 14 days (2 rules)
New Subscribers	Subscribed in the last 7 days (1 rule)
At Risk	Subscribed 30+ days and never clicked a notification (2 rules)
Dormant	Last seen more than 60 days ago (1 rule)
Mobile Only	Subscribers on mobile devices (1 rule)
Desktop Only	Subscribers on desktop devices (1 rule)
Tablet Only	Subscribers on tablet devices (1 rule)
Recently Clicked	Clicked a notification in the last 7 days (1 rule)

To use one, click Use Template on the card. The segment is created immediately and appears in Your Segments below — open it any time to rename it or refine the rules.

warning

Deleting a segment doesn't affect:

Best Practices

Keep Segments Focused

• One clear purpose per segment
• Avoid overly complex rules
• Document with descriptions

Name Clearly

Good: "US Mobile Users - High Engagement" Bad: "Segment 1"

Test Before Using

• Check the audience count
• Send test notifications to yourself first
• Monitor performance

Review Regularly

• Audience sizes change over time
• Remove unused segments
• Update rules as needed

Combine with Categories

Use segments with delivery categories for powerful targeting:

• Segment: "Sports fans"
• Category: "Breaking news"

Segment Limits

Limit	Value
Rules per segment	Maximum 10
Segments per app	Unlimited
