With a 98% open rate vs email's 20%, WhatsApp is not just a messaging app — it's the highest-performing marketing channel for businesses in 2025.
The Numbers Side by Side
Here is the data that makes every marketer switch channels. This comparison is based on aggregated data from 5,000+ campaigns run through WhatsApp Global's platform in 2024–2025.

Why WhatsApp Open Rates Are So High
WhatsApp messages appear as personal notifications — the same place where messages from friends and family arrive. Unlike promotional email folders or SMS streams that get ignored, WhatsApp messages carry an inherent urgency. People check WhatsApp an average of 23 times per day.
Additionally, WhatsApp messages are opt-in only through the official API, meaning your audience has explicitly agreed to receive messages. This self-selection creates an inherently more engaged audience than purchased email lists.
When Email Still Makes Sense
Email marketing is not dead — it excels in certain scenarios. Long-form content like newsletters, detailed reports, and complex product documentation work better in email because of its document-like format. Email also has a lower per-message cost at high volume and has been around long enough that most businesses have extensive lists.
The winning strategy for most businesses in 2025 is a combined approach: use WhatsApp for time-sensitive, high-priority communications (flash sales, cart recovery, appointment reminders), and email for longer-form content and relationship nurturing.

Real Campaign Comparison: Same Product, Two Channels
One of our e-commerce clients (fashion retail, India) ran identical promotions simultaneously on WhatsApp and email for their year-end sale campaign. Here were the results after 48 hours:
| Metric | WhatsApp Campaign | Email Campaign |
|---|---|---|
| Recipients | 45,000 | 45,000 |
| Opened / Delivered | 44,100 (98%) | 9,000 (20%) |
