Advanced Strategies

| Segment | Characteristics | Strategy | |---------|-----------------|----------| | Champions | Recent, frequent, high spend | Exclusive offers, loyalty rewards | | Loyal | Frequent buyers | Upsell, cross-sell | | At Risk | Previously good, inactive | Win-back campaigns | | New | Recent first purchase | Nurture, second purchase incentive |

Use AI for:

Next product to buy
Optimal send time
Churn prediction
Lifetime value prediction

3. Interactive Emails

Add engagement elements:

Countdown timers
Polls and surveys
Add-to-cart functionality
GIFs and animations

4. Cross-Channel Integration

Coordinate with:

SMS for urgency
Push notifications

Direct mail for VIPs

Common Mistakes to Avoid

1. Sending to Everyone

One message doesn't fit all. Segment and personalize.

2. Over-Sending

Email fatigue kills engagement. Test frequency, segment by engagement.

3. Ignoring Mobile

Most opens are mobile. Design mobile-first.

4. No Testing

Assumptions are often wrong. A/B test continuously.

5. Neglecting Deliverability

If emails don't arrive, nothing else matters. Clean list, authenticate domain, monitor reputation.
