WhatsApp for B2B sales — opt-in, templates, and what converts
WhatsApp gets the highest reply rate for SMB outreach, but only with Meta-approved templates and opt-in. Use it as a warm second touch, never a cold blast. Here's the compliant playbook.
Short answer: WhatsApp is the highest-reply channel for SMB B2B — but only with Meta-approved templates and real opt-in. The 24-hour conversation window opens once the recipient messages first or an approved template lands. Run it as a warm second touch after an email or call, never as a cold blast. Fire unsolicited marketing templates and Meta suspends them fast.
The compliant play
- Open elsewhere — email, LinkedIn, or a call — to set the context.
- Follow up on WhatsApp with an approved utility or notification template.
- The conversation window opens on their reply → free-form for 24h.
- Honour opt-out as a cross-channel DNC.
Why it converts
It's where SMB buyers actually open and read. With consent, reply rates beat email. As spam, your number gets banned. Same channel, opposite outcomes.
