# Re-Engagement Campaign Builder

Re-activate dormant subscribers and win back lost customers with strategic, multi-touch re-engagement campaigns.

## Workflow

1. Define inactivity thresholds: 30 days, 60 days, 90 days, 180 days (based on send frequency and industry).
2. Segment inactive subscribers by last engagement date, lifetime value, and subscription source.
3. Analyze reasons for disengagement: content relevance, frequency fatigue, product changes, competition.
4. Design re-engagement sequence: 3–5 touches over 14–30 days with escalating urgency and incentives.
5. Create personalized messaging: reference past engagement, purchase history, content preferences.
6. Offer compelling incentives: exclusive content, discounts, surveys, preference center, or simple "are you still interested?"
7. Implement automated branching: re-engaged vs. still inactive paths.
8. Execute final "goodbye" email with preference options and clean unsubscribes.
9. Measure re-engagement rate, re-subscribe rate, and revenue recovery.
10. Continuously optimize thresholds, messaging, and incentives based on data.

## Inactivity Segmentation

```
INACTIVITY THRESHOLD DEFINITIONS
=================================

THRESHOLDS BY INDUSTRY AND SEND FREQUENCY:

  DAILY NEWSLETTERS / MEDIA:
    → At Risk: No open in 14 days
    → Inactive: No open in 30 days
    → Dormant: No open in 60 days
    → Dead: No open in 90 days
    → Rationale: Daily sends mean quick decay — 2 weeks is significant

  WEEKLY NEWSLETTERS / B2B MARKETING:
    → At Risk: No open in 30 days (missed 4+ emails)
    → Inactive: No open in 60 days (missed 8+ emails)
    → Dormant: No open in 90 days (missed 12+ emails)
    → Dead: No open in 180 days (missed 24+ emails)

  E-COMMERCE / TRANSACTIONAL:
    → At Risk: No purchase in 90 days
    → Inactive: No purchase in 180 days
    → Dormant: No purchase in 365 days
    → Dead: No purchase in 540+ days
    → Note: Email engagement tracked separately from purchases

  SaaS / PRODUCT-LED:
    → At Risk: No login in 14 days
    → Inactive: No login in 30 days
    → Dormant: No login in 60 days
    → Dead: No login in 90 days
    → Rationale: Product usage = true engagement; email opens are secondary

LIFETIME VALUE SEGMENTATION (cross-cutting):

  HIGH LTV (Top 20% of customers/subscribers):
    → Revenue: $1,000+ lifetime value or equivalent engagement
    → Treatment: Personal outreach, phone calls, significant incentives
    → Recovery ROI: Highest — worth maximum effort

  MEDIUM LTV (Middle 50%):
    → Revenue: $100–$1,000 lifetime value
    → Treatment: Automated re-engagement sequence with moderate incentive
    → Recovery ROI: Good — automated approach is cost-effective

  LOW LTV (Bottom 30%):
    → Revenue: <$100 lifetime value or never converted
    → Treatment: Basic re-engagement sequence, low incentive
    → Recovery ROI: Low — efficient cleanup is priority

  NEVER-CONVERTED (subscribers who never purchased):
    → Treatment: Content re-engagement, lead nurturing reset
    → Incentive: Valuable content or resource (not discount)
    → Goal: Move from subscriber to customer
```

## Re-Engagement Sequence Design

```
5-EMAIL RE-ENGAGEMENT SEQUENCE (21-Day Campaign)
===================================================

EMAIL #1 — SOFT CHECK-IN (Day 1)
==================================

TIMING: Day 1 of inactivity threshold breach

SUBJECT LINES:
  A: "We miss you, {{first_name}}"
  B: "Is everything okay?"
  C: "Just checking in..."

PREHEADER: "We noticed you haven't been around lately — wanted to check in."

BODY:
  Hi {{first_name}},

  We noticed you haven't opened our emails in a while. We wanted to check in
  and make sure you're still getting value from us.

  If our emails aren't relevant anymore, no hard feelings — we just want to
  make sure you're getting what matters to you.

  [PERSONALIZATION: reference their last engagement]
  "Your last read was '[article title]' on [date]. We have some new content
  on similar topics you might enjoy:"

  [3 RELEVANT CONTENT LINKS based on past engagement]

  [BUTTON: "Show Me What's New"]

  PS: Reply to this email if there's something specific you'd like to see.
  We read every response.

DESIGN NOTES:
  → Casual, human tone (not salesy)
  → No discount (yet)
  → References past engagement (shows you know them)
  → Soft CTA (curiosity-driven)


EMAIL #2 — VALUE REMINDER (Day 7)
===================================

TIMING: 7 days after Email #1 (if no engagement)

SUBJECT LINES:
  A: "What you've been missing..."
  B: "Here's what happened while you were away"
  C: "You've got {{number}} new items waiting"

BODY:
  Hi {{first_name}},

  A lot has happened since you last visited. Here's a quick catch-up:

  [HIGHLIGHTED UPDATES — 3–5 items]
  ✦ [New feature/product launch with image]
  ✦ [Popular content/article from last 30 days]
  ✦ [Customer success story or testimonial]
  ✦ [Industry insight or data point]
  ✦ [Upcoming event or webinar]

  [PERSONALIZED RECOMMENDATION]
  "Based on your interests in [topic], you might love:"
  [Product/content recommendation]

  [BUTTON: "Catch Up Now"]

  We'd love to have you back.

DESIGN NOTES:
  → "What you missed" framing (FOMO)
  → Visual-rich with images/thumbnails
  → Social proof elements
  → Still no discount — building value case


EMAIL #3 — PREFERENCE CENTER (Day 12)
========================================

TIMING: 12 days after Email #1 (if no engagement)

SUBJECT LINES:
  A: "Let's make this better for you"
  B: "Help us send you better emails"
  C: "{{first_name}}, how do you want to hear from us?"

BODY:
  Hi {{first_name}},

  We want to send you emails you actually want to read.

  Help us improve by telling us what you prefer:

  [INTERACTIVE PREFERENCE CENTER]
  ▢ What topics interest you?
     [ ] Topic A    [ ] Topic B    [ ] Topic C    [ ] Topic D

  [ ] 30 days    [ ] 60 days    [ ] 90 days    [ ] Indefinitely

  We'll respect your choice — no guilt trips, we promise.

DESIGN NOTES:

EMAIL #4 — INCENTIVE OFFER (Day 17)
=====================================

TIMING: 17 days after Email #1 (if no engagement)

SUBJECT LINES:
  A: "We'd love to win you back — here's 20% off"

  Offer expires: [Date — 7 days from now]

  [BUTTON: "Claim My Discount"]

```

## Incentive Strategy

```
RE-ENGAGEMENT INCENTIVE FRAMEWORK
===================================

INCENTIVE TYPES BY INDUSTRY:

    → Percentage discount: 15–30% (escalating across sequence)
    → Dollar amount off: $10–$50 off (absolute value > percentage for high-ticket)

INCENTIVE ESCALATION RULES:
  → Email #1: No incentive (test organic interest)
  → Email #2: No incentive (value reminder)
  → Email #3: Preference center (soft commitment, no discount)
  → Email #4: Standard incentive (20% off or equivalent)
  → Email #5: Maximum incentive (30% off or best offer)

COST OF INCENTIVE vs. COST OF ACQUISITION:
  → CAC benchmark: $50–$200 per new customer (varies by industry)
  → Retention cost: $5–$20 per re-engaged customer
  → ROI rule: If re-engagement cost < 25% of CAC, it's a good investment
  → Example: CAC $100 → willing to spend $25 to win back → 20% off $50 avg order = $10 → ROI 10x
```

## Performance Measurement

```
RE-ENGAGEMENT CAMPAIGN METRICS
================================

KEY METRICS TO TRACK:

  RE-ENGAGEMENT RATE:
    → Formula: (Re-engaged subscribers / Total inactive subscribers) × 100
    → Definition of "re-engaged": Opened OR clicked any re-engagement email
    → Benchmark: 8–15% overall re-engagement rate
    → By segment: High LTV = 15–25%, Medium LTV = 8–12%, Low LTV = 3–8%

  RE-SUBSCRIPTION RATE (for goodbyes):
    → Formula: (Re-subscribed after unsubscribe / Total unsubscribes) × 100
    → Benchmark: 2–5% re-subscription after goodbye
    → Indicates: How many truly wanted to stay but needed push

  REVENUE RECOVERY:
    → Revenue from re-engaged customers within 30 days
    → Average order value of re-engaged vs. never-inactive customers
    → Benchmark: $0.50–$2.00 recovered per inactive subscriber

  UNSUBSCRIBE RATE:
    → Expected: 15–30% of inactive subscribers will finally unsubscribe
    → This is POSITIVE — cleans list, improves sender reputation
    → Remaining inactive non-responders: suppress/remove automatically

  CAMPAIGN COST vs. RETURN:
    ┌──────────────────────┬────────────┬────────────┬──────────┐
    │ Metric               │ Cost       │ Return     │ ROI      │
    ├──────────────────────┼────────────┼────────────┼──────────┤
    │ 10,000 inactive subs │ $200 (ESP) │ $15,000    │ 7,400%   │
    │ Re-engaged: 1,200    │            │            │          │
    │ Revenue recovered    │ $500 (disc)│            │          │
    │ Incentive cost       │            │            │          │
    └──────────────────────┴────────────┴────────────┴──────────┘

  LIST HEALTH IMPROVEMENT:
    → Pre-campaign engagement rate: X%
    → Post-campaign engagement rate: Y% (typically +15–30% improvement)
    → Spam complaint rate: Should decrease (inactive subscribers removed)
    → Deliverability score: Should improve (better engagement = better reputation)
    → Sending costs: Reduced (fewer emails to non-engaged subscribers)

  LONG-TERM IMPACT (track 90 days post-campaign):
    → Re-engaged subscribers' ongoing engagement rate
    → Revenue contribution of recovered customers over 90 days
    → Churn rate of re-engaged vs. never-inactive subscribers
    → Net list growth (new subs minus final unsubscribes minus suppressions)
```

- Amplitude / Mixpanel: Product usage data for SaaS re-engagement triggers

## Edge Cases

- **High-volume lists (100K+)**: Segment re-engagement campaigns to avoid sending to 100K+ inactive subscribers simultaneously. Send in batches of 5,000–10,000 per day to protect sending reputation. Monitor complaint rates closely during campaign.
- **VIP / enterprise customers**: Never use automated re-engagement for key accounts. Assign personal CSM outreach: phone call, personalized email from leadership, dedicated value review. Automated discount offers to enterprise customers can devalue the relationship.
- **B2B long sales cycles**: "Inactivity" means different things in B2B — a 6-month engagement gap may be normal for enterprise deals. Adjust inactivity thresholds based on average sales cycle length. Never treat an active sales opportunity as "inactive" just because they haven't opened emails.
- **Regulatory compliance for re-engagement**: GDPR: Ensure original consent covered re-engagement communications. If consent was specific (e.g., "order updates only"), marketing re-engagement needs separate consent. CAN-SPAM: Include physical address and unsubscribe in every re-engagement email. CCPA: Honor "do not sell" preferences in re-engagement.
- **Post-re-engagement nurturing**: Re-engaged customers need immediate follow-up to establish new engagement patterns. Trigger a "welcome back" onboarding sequence after re-engagement: Day 1 welcome back email, Day 3 personalized recommendation, Day 7 check-in. Don't just re-engage and drop them back into standard cadence.
