Meta changes WhatsApp prices on 1 October 2026. Support replies in the 24-hour window are no longer free. This 1MSG guide shows what that means for your invoice, and how to keep extra cost small.

Meta began sending the Business-Scoped User ID (BSUID) instead of a phone number in some WhatsApp webhooks starting April 2026 — the biggest identity shift this platform has seen since it first launched. Sending to a known phone number still works, and 1MSG already maps BSUID back to phone so missing numbers still resolve to the right contact.

Bulk WhatsApp messaging scales only on the official WhatsApp Business API: opted-in recipients, a Meta-approved template, and a throttled sendTemplate loop. New portfolios start at 250 unique recipients per rolling 24 hours, scaling to 2,000, 10,000, 100,000, then unlimited. Track every send by wamid and halt before the cap.
