# Bounce guard threshold

# Bounce guard threshold

## Purpose

Explains SuperSend’s automatic pause when **invalid-recipient** bounces run high, and how to set the **Bounce Guard Threshold (%)** per campaign in Settings.

## Prerequisites

- Access to the campaign’s **Settings**
- Understanding that this guard looks at **invalid-recipient** bounces (bad or unreachable addresses), not all bounces

## Steps

1. Open the campaign.
2. Click **Settings** in the campaign navigation.
3. In the settings sidebar, select **Campaign**.
4. Find **Bounce Guard Threshold (%)**.
5. Enter a whole-number percentage from **1** to **100** (default is **3**).
6. Save your campaign changes as you normally do for this page.

SuperSend shows a warning if you set the threshold **above 10%** — raising it can hurt sender reputation if your list quality is poor.

## Expected Result

- While the campaign is **on**, SuperSend monitors email sends after the bounce checkpoint. If the share of **invalid-recipient** bounces in the evaluation window exceeds your threshold, the campaign **pauses automatically** and a lifecycle reason reflects the bounce guard.
- Each campaign stores its own threshold; there is no separate global override in the app.

## Troubleshooting

- **Issue:** The campaign turned off on its own and I did not click pause.  
  **Fix:** Open **Events** or your notifications and check for an automatic pause tied to bounce rate. Review contact quality and [Email Validation in SuperSend](https://help.supersend.io/en/article/email-validation-in-supersend-umb5lo/). Lower the threshold or clean the list before re-enabling.

- **Issue:** I want fewer automatic pauses.  
  **Fix:** You can raise **Bounce Guard Threshold (%)** only if you accept deliverability risk. Prefer verifying contacts and fixing list sources first.
