The Core Numbers
Email open rate in India: 18–22%. WhatsApp open rate: 90–98%. Click-through rate for email: 2–3%. For WhatsApp: 15–40%. For a brand sending 10,000 messages, email reaches 2,000 openers and 200–300 clickers. WhatsApp reaches 9,000+ openers and 1,500–4,000 clickers. Same list, same message, dramatically different results.
Why WhatsApp Opens Get Read
Notification psychology — WhatsApp notifications carry personal communication weight. People open reflexively.
Less competition — An inbox has hundreds of emails. A WhatsApp chat has far fewer brand messages.
Opt-in quality — WhatsApp Business API only allows messaging opted-in contacts. Warmer leads by definition.
Mobile-first format — WhatsApp is mobile-native. Short messages and quick responses fit the format.
Where Email Still Wins
Long-form content — newsletters, product guides, and detailed announcements read better in email
B2B professional communication — enterprise decision-makers still prefer formal email
Archiving and reference — customers who need to refer back to invoices or receipts prefer email
Volume cost — email is cheaper than WhatsApp API messaging at very high volumes
The Right Answer: Use Both, for Different Jobs
WhatsApp and email are not competitors — they serve different stages of the customer journey. The brands seeing the best results use email for top-of-funnel content (newsletters, launches, educational content) and WhatsApp for mid-to-bottom-funnel conversion (cart recovery, appointment reminders, personalised offers, post-purchase follow-up).
