Definition
Burst sending is releasing a large volume of email in a short time window. It can overwhelm receiving systems and trigger throttling.
Paced sending is safer, and any volume increase should be warmed up gradually.
Burst sending is a common but risky pattern that triggers throttling and temporary deferrals. Pacing volume smooths load and protects placement. Warming up any increase gradually is the safer alternative.
Why Bursts Are Risky
Bursts hit rate limits and cause temporary deferrals.
They can lower opens as filters react.
Why It Matters
Burst sending is a common but risky pattern that triggers throttling. Understanding why helps you pace sends for better delivery.
Best Practices

- Monitor deferrals during large sends.
