+### 3.1. Rate Limiting
+
+**Important**: The command automatically rate limits to **50 emails per day** to avoid overwhelming your email service and to maintain good sender reputation.
+
+For example:
+- **50 users**: All sent immediately
+- **125 users**: 50 sent today, 50 tomorrow, 25 the day after
+- **250 users**: 50 per day over 5 days
+
+The command will show you the schedule:
+```
+Found 126 user(s).
+Rate limit: 50 emails per day
+Successfully queued 126 update email(s) to the 'emails' queue!
+Emails will be sent over 2 day(s) (50 emails per day)
+```
+
+Jobs are queued with delays automatically - you don't need to do anything special!
