# Configure Global Send Limits (Throttling)

Mass Email Notifications lets you control how quickly emails are sent,
so you never overwhelm your host or exceed your provider’s limits. These
rules apply across all feeds and batches.

------------------------------------------------------------------------

## Available Limits

You can set caps for:

- **Per-minute**
- **Per-hour**
- **Per-day**
- **Per-month**

Each limit type can be used alone or combined. For example, you could
allow 100 per hour *and* 500 per day.

------------------------------------------------------------------------

## Reset Types

- **Fixed Reset**: Resets at the same time every cycle (e.g., midnight
  daily).
- **Rolling Reset**: Resets based on a moving window (e.g., the past 24
  hours).
- **Custom Monthly Reset Day**: Choose which day of the month your
  monthly cap resets — handy if your plan runs on a billing cycle other
  than the 1st.

------------------------------------------------------------------------

## Best Practices

- **Be Conservative**: Enter a lower number than your provider’s
  published limits. This leaves room for other WordPress emails (like
  password resets or order confirmations) that also count toward your
  quota.
- **Plan for All Sites**: If you’re running multiple sites on the same
  email plan (including WordPress multisite), divide your real limits
  across them. For example, if your provider gives you 20,000 per month
  and you run five sites, aim for about 4,000 per site.
- **Combine Safely**: Use compound rules (minute + hour + day + month)
  to prevent sudden spikes while keeping long-term totals under control.

------------------------------------------------------------------------

## What Happens at the Limit?

When any cap is reached, Mass Email Notifications automatically pauses
the batch. Sending resumes automatically once the next reset window
opens.

------------------------------------------------------------------------

By setting thoughtful global limits, you protect your sending
reputation, avoid unexpected charges, and keep campaigns flowing
smoothly.
