Throughput
How many messages per second a WhatsApp number is permitted to send. Meta sets it per number and raises it as the number demonstrates healthy sending behaviour.
One term from the WhatsApp Business Platform glossary. Last updated 2026-07-25.
Throughput is separate from the messaging limit. The messaging limit caps how many unique customers you can start conversations with in a day; throughput caps how fast you can push messages out at any moment.
For a large broadcast, throughput determines how long the send takes rather than whether it is allowed. A good platform paces sends against the number's actual throughput instead of firing everything at once and collecting rate-limit errors.

- Messaging limit (tier)
- The cap on how many unique customers your WhatsApp number may start conversations with in a rolling 24 hours. Numbers move up tiers — 1,000, 10,000, 100,000, then unlimited — as volume and quality rating hold up.
- Quality rating
- The health score Meta assigns each WhatsApp phone number, derived from how recipients react to its messages. Blocks and reports push it down, and a low rating restricts the number's messaging limit.
- Broadcast
- A single WhatsApp template message sent to a defined segment of contacts at once. Each recipient receives it as an individual conversation, not a group chat.
