Template A/B tests on WhatsApp require small cells, clear metrics and quality guardrails, not duplicate spam.
Why this matters in 2026
Businesses moving off unofficial bulk senders need operational playbooks that respect Meta quality rating, DPDP/GDPR consent and measurable ROI. This article is written for teams implementing A/B Testing WhatsApp Marketing Templates at Scale on the Cloud API, not WhatsApp Web hacks.
