"I want to send reminders to people who didn't open the birthday email" "I want to follow up with people who haven't used their coupon"
HubSpot workflows can set up branches based on email open and click status, automating follow-ups.
Importance of Follow-up
Simply sending a birthday email doesn't always lead to coupon usage.
| Challenge | Cause | Solution |
|---|---|---|
| Email not seen | Buried among other emails | Send reminder email |
| Opened but no action | Timing wasn't right | Expiration reminder |
| Forgot about coupon | Planned to use later | Pre-expiration notice |
Follow-up Patterns
Pattern 1: Reminder for Non-openers
Main birthday email sent
Branch by open status
Send reminder "Don't forget your birthday offer"
No follow-up needed (end) or different follow-up
Pattern 2: Opened but No Click
Email with coupon link
Branch by click status
"Get your coupon here" reminder email
Pattern 3: Coupon Expiration Reminder
7-day valid coupon
Check usage status from CRM property
"Only 2 days left! Coupon expiration notice"
Configuration Steps
1. Add Branch Condition
After birthday email send, add if/then branch.
- Add delay after email send action
- Add "if/then branch"
- Condition: Marketing email activity
- Select "Opened [Birthday email]"
2. Actions for Non-openers
Set reminder email in the "No" branch.
Reminder email tips:
- Change subject line (same one will be ignored)
- Convey urgency ("Only X days left")
- Restate offer details
3. Actions for Openers (Optional)
Add situation-appropriate follow-up for the opened branch.
Email Open Tracking Notes
Tracking Limitations
| Situation | Trackable | Reason |
|---|---|---|
| Normal open | Yes | Tracking pixel loads |
| Images disabled | No | Pixel doesn't load |
| Apple Mail Privacy | Inaccurate | Auto-loads pixel |
| Plain text view | No | No images displayed |
Recommendation
Include clicks (more reliable) in addition to opens as conditions.
Follow-up Email Design
Non-opener Reminder
Subject examples:
- "John, did you forget your birthday offer?"
- "[4 days left] Your birthday coupon is expiring soon"
Content structure:
- Reminder purpose
- Offer details (repeat)
- Expiration date
- CTA (prominent button)
Delivery Frequency Management
Prevent Over-delivery
Too many follow-ups can be excessive.
Recommended rules:
- Maximum 3 birthday-related emails
- At least 2-3 days between emails
- Avoid overlap with other promotions
Effectiveness Measurement
| Metric | Calculation | Target |
|---|---|---|
| Reminder open rate | Reminder opens / sent | 35%+ |
| Post-reminder CV rate | Post-reminder purchases / reminder sent | 8%+ |
| Overall CV rate improvement | With follow-up CV - without follow-up CV | +5%+ |
Summary
- Remind non-openers: Re-send 3-5 days later
- Check click status too: More reliable than opens
- Pre-expiration notice: Prevent expiration
- Manage frequency: Over-delivery is counterproductive
- Measure and improve: Verify reminder effectiveness
Appropriate follow-up maximizes birthday coupon redemption rates.
