Part 1: Why Generic Emails Fail (The Data)

The Harsh Reality of Email Marketing in 2025

Indian D2C Email Benchmarks:

Generic Emails:
- Open rate: 12-22%
- Click rate: 1.5-3%
- Unsubscribe rate: 2.8%
- Revenue per email: ₹320-680

Personalized Emails:
- Open rate: 35-58% (+180%)
- Click rate: 6-12% (+280%)
- Unsubscribe rate: 0.4% (-86%)
- Revenue per email: ₹1,200-2,400 (+320%)

The inbox reality:

• Average Indian receives 47 marketing emails daily
• Reads 4-6 of them (12%)
• Deletes rest without opening

Your email competes with:

• Personal emails (friends, family)
• Work emails (urgent)
• WhatsApp notifications (immediate)
• 46 other marketing emails (ignored)

To win: Be relevant. Be personal. Be useful.

What "Personalization" Actually Means

NOT personalization:

"Dear {{First_Name}}," ← This is mail merge, not personalization

IS personalization:

Subject: Priya, your Mysore Silk saree ships tomorrow

Hi Priya,

Good news! The Mysore Silk saree you ordered 
(Royal Blue, Size 38) is being packed right now.

Expected delivery: Thursday, 2-4 PM at your 
Indiranagar address.

Since you loved our silk collection, I thought 
you might like these matching blouse pieces...
