Definition
Throttling rules limit how many messages a provider delivers per interval, protecting infrastructure and reputation.
Exceeding the limit causes deferrals, bounces, and reputation hits.
Throttling is how providers protect infrastructure, and respecting it protects your delivery. Pacing sends and handling errors with backoff prevents delays and blocks. Knowing your limits before planning big sends is essential.
Working Within Limits
Know your provider limits before planning big sends.
Pace sends rather than bursting to the limit.

Best Practices
- Know your provider limits before planning big sends.
