WhatsApp broadcast limits & messaging tiers explained (2026)
What Meta's messaging tiers mean, how they limit your broadcast volume, and how to climb from 250 to unlimited conversations per 24 hours.
WhatsApp doesn't let a new business number send a million messages on day one — there are tiered limits that climb as you build trust. Understanding these tiers is essential for planning campaigns, especially around peak seasons. Here's how they work in 2026.
The tier ladder
New numbers start at 250 unique customers per rolling 24 hours (unverified) or 1,000 (TIER_1K). As you send more quality messages without high user-reported-spam rates, Meta upgrades you: 10K, 100K, and eventually unlimited. Your current tier shows on the AiConva dashboard as 'Messaging Limit'.
Quality gates the climb
The lever that moves you up (or down) is quality — specifically, how often recipients report your messages as spam or block you. High-quality, relevant, opted-in messaging climbs fast. Generic blasts to poorly-segmented lists stall or downgrade your tier. This is why segmentation isn't optional — it protects your sending reputation.
Planning around limits
For a festive campaign to 50,000 contacts on a 10K-tier number, you'll send in batches across multiple 24-hour windows. AiConva's campaign engine handles batching automatically — you set the audience, it paces the sends to respect the tier. Plan ahead of Diwali/Eid so tier upgrades have time to process before peak.
