Overview
An SMS-only popup is designed to target visitors who:
Have already subscribed to email
Have NOT yet subscribed to SMS
This typically captures users who:
Dropped off before entering their phone number
Need a second touchpoint to convert
Goal:
Drive incremental SMS opt-ins from already-engaged visitors.
How It Works
This popup should:
Trigger on return visits (second session or later)
Only target users who:
✅ Completed email signup
❌ Did NOT complete SMS signup
⚠️ Important Targeting Rules (Applies to ALL Setups)
Before setting up integrations, make sure:
❌ Do NOT target “New Visitors”
✅ Only target the segments/rules defined below
✅ Enable the following setting in the popup editor:
“Don’t trigger if another popup viewed in the last X days”
Recommended: 1–2 days

Summary
To successfully implement an SMS-only popup:

Avoid new visitor targeting
Throttle popup frequency (1–2 days)
Done correctly, this setup is one of the highest ROI ways to grow SMS lists, capturing users who already showed intent but didn’t fully convert.
