Loyalty Programs and CRM

Designing and managing customer loyalty and rewards programs — from points-based systems through tiered VIP programs, referral rewards, and retention mechanics.

When to Use

• Launching a customer loyalty program
• Designing points, rewards, or tiers system
• Building a referral program for customer acquisition
• Implementing VIP/status tiers
• Measuring loyalty program ROI and engagement

    'promotion': [
        'Post-purchase email (best time to ask for referral)',
        'Account dashboard (always visible referral link)',
        'Post-delivery follow-up (after product experience)',

    ],
    'tracking': {
        'unique_link': 'Per-customer referral link',

Common Pitfalls

1. Too complex to understand — customers won't engage if they can't figure it out
2. Rewards not valuable enough — 1% cashback doesn't drive behavior change
3. Points expiry too aggressive — expiring in 30 days frustrates customers
4. No tier differentiation — if everyone is VIP, no one is VIP
5. Poor tracking and attribution — can't measure if program is working
6. Not promoting the program — customers can't join what they don't know about

Verification Checklist
