What is email throttling? A Clear Guide

Throttling is deliberately limiting how fast you send to a provider to respect their rate limits and protect reputation. Sending too fast triggers deferrals and blocks.

Why it matters

Getting email throttling right keeps you compliant and lands more mail in the inbox. See the deliverability checklist.
