Designs sequences (welcome, nurture, reactivation, win-back, review, referral) grounded in 2025-2026 benchmarks, AI-driven personalization, and post-Apple MPP measurement.
Every campaign targets a specific segment defined by at least two attributes (e.g., language + lifecycle stage, or transaction type + engagement recency). Single-attribute segments are acceptable only for basic reporting.
A Won client never receives a cold nurture email. A Lost lead never receives a review request. A contact marked Irrelevant never enters any sequence. Email strategy reflects where contacts ARE now, not where they were at capture.
Post-Apple MPP (40-60% of most lists use Apple Mail), open rates are inflated and unreliable. CTR, CTOR, and conversion rate are the real performance indicators. Never use open rate as the sole success metric. Average 2025 open rate was 43.46% across industries -- but this number is meaningless for optimization.
Every automated sequence defines explicit exit conditions: conversion achieved, unsubscribe received, hard bounce detected, complaint filed, inactivity threshold reached, duplicate detected. No sequence runs indefinitely.
One bad email (phone concatenated in email field, invalid domain) can crash an entire batch. Validate at capture (regex + MX check for bulk imports). Remove hard bounces immediately. Run quarterly list verification. Clean data = clean reputation.
Consent is not a checkbox -- it's documented (date, method, source, scope), withdrawable (one-click), and auditable (GDPR Article 7). Never assume consent from a static list import. Double opt-in is the safest approach even though it's not legally mandatory in all jurisdictions.
Transactional emails (confirmations, status updates) use a separate sender/IP pool with pristine reputation. Never inject marketing content into transactional emails.
## [Sequence Name] — Design Spec
### Trigger
- Event: [CRM status change / form submission / time-based / behavioral]
- Delay: [immediate / X hours / X days after trigger]
### Segment
- Attributes: [LANGUAGE=EN, LEAD_STATUS=Won, TRANSACTION=Buy, Last Action > 7 days]
- Exclusions: [Already in sequence / Irrelevant / Suppressed]
### Emails
| # | Timing | Subject (A/B) | Content Focus | CTA | Exit If |
|---|--------|---------------|---------------|-----|---------|
| 1 | Day 0 | "A" / "B" | Welcome + value prop | Explore properties | Unsub |
| 2 | Day 3 | "A" / "B" | Social proof | Book consultation | Converts |
| 3 | Day 7 | "A" / "B" | Market insights | View listings | Bounces |
### Exit Conditions
1. Converts (submits inquiry / books call)
2. Unsubscribes
3. Hard bounce
4. Spam complaint
5. Inactivity > 90 days (move to win-back)
### Metrics & Targets
| Metric | Target | Alert Threshold |
|--------|--------|-----------------|
| CTR | > 3% | < 1.5% |
| CTOR | > 10% | < 5% |
| Unsub rate | < 0.5% | > 1% |
| Complaint rate | < 0.10% | > 0.20% |
### Compliance
- [ ] Consent basis: [opt-in / legitimate interest]
- [ ] Unsubscribe: one-click (RFC 8058)
- [ ] Sender identity: [name + verified domain]
- [ ] Physical address: [if required by jurisdiction]
## CRM → ESP Attribute Map
| CRM Field | ESP Attribute | Type | Values | Sync |
|-----------|--------------|------|--------|------|
| Lang | LANGUAGE | category | EN=1, BG=2, FR=3 | Zapier (capture) + n8n (update) |
| Status | LEAD_STATUS | category | Lost=1, Gave Up=2, Active=3, Won=4, 1st Contact=5 | n8n (on status change) |
| Transaction | TRANSACTION | category | Buy=1, Sell=2, Rent=3, Rent Out=4, Other=5 | n8n (when agent updates) |
| Name | FIRSTNAME | text | Free text | Zapier (capture) |
Notes:
- Category attributes require numeric IDs, not text values
- Empty/null: skip attribute in upsert, don't overwrite with empty
- Case-sensitive in most ESPs

Send-Time Optimization (STO): AI predicts each contact's optimal engagement window based on historical click patterns. Measured lift: 15-23% higher open rates. Critical: modern STO must analyze clicks and conversions, not opens (Apple MPP spoofs opens). Requires 30+ days of engagement data per contact. Available natively in Brevo from Standard plan.
Subject Line AI: Generate 3-5 variants, A/B test on 10-20% sample, auto-deploy winner. eBay case study: 15.8% open rate lift, 31% increase in clicks. 64% of email marketers now use AI in their programs; AI personalization drives 41% average revenue increase.
Brevo Aura AI (launched May 2025): Chat-style assistant in dashboard and email editor. Generates subject lines, body copy, CTAs, tone adjustments, multilingual translations. Available on free plan.
Generative Review Suggestions: Use LLMs (Claude Haiku) to generate personalized Google Review suggestions based on transaction type, language, and client name. Inject via template params ({{ params.SUGGESTED_REVIEW }}). Include in review request emails as copy-paste inspiration.
