Email is the workhorse with decades of tooling. WhatsApp is the upstart with 98% open rates. The answer depends almost entirely on your market.
The short answer
Email wins for Western markets (US, UK, EU) where inbox habits are mature and B2B lives there. WhatsApp wins decisively in UAE, India, SEA and LatAm where commerce happens in chat - 98% open rates and reply rates around 3x email. Run both: email for depth (newsletters, nurture, receipts), WhatsApp for speed (carts, bookings, reorders). Our lifecycle programs routinely drive 20-35% of client monthly sales from these two channels combined.
The retention workhorse
Best for: Western consumer markets, B2B nurture, long-form content and receipts
Typical cost: Platform fees scale with list size; near-zero send cost
The conversation closer
Best for: UAE, India, SEA, LatAm commerce; carts, bookings, reorder flows, high-touch sales
Typical cost: API conversation pricing; trivially low versus recovered revenue
When customers are in North America or Europe

When customers are in Gulf, South Asia or SEA

Our verdict
It is not either-or; it is sequence design. Email nurtures and documents, WhatsApp accelerates and closes. LuminSkin's Nigeria program and NestRealty's Dubai funnel both printed because WhatsApp carried the close while email carried the relationship.
In chat-first markets we see WhatsApp flows recover carts at 2-3x email's rate for identical audiences. In Western markets email still outperforms for content-led nurture. Blended programs beat single-channel in every market we have tested.
Only if you buy lists or skip opt-ins. Consent-first funnels, template compliance and quality-score monitoring keep accounts healthy - our portfolio has zero banned numbers to date.
