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 when you use Meta-approved templates and respect opt-in. The 24-hour conversation window opens after the recipient messages first or an approved template lands. Use WhatsApp as a warm second touch (after an email or call), never as a cold blast — unsolicited marketing templates get suspended fast.
The compliant play
- First touch elsewhere (email/LinkedIn/call) to establish context.
- Approved utility/notification template on WhatsApp as the follow-up.
- 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 read messages. Done with consent, reply rates beat email. Done as spam, your number gets banned.
