We will automatically pause campaigns when the bounce rate exceeds 5% to protect your sender reputation and deliverability. This feature is enabled by default for all users.
Campaigns must send at least 200 emails before this check runs.
Click the Gear icon next to the toggle to customize the bounce rate threshold that triggers a pause(Default is 5%) in Preferences. You can also disable the 'Automatically pause campaigns with high bounce rates' feature as needed.
You will see a "Bounces" error message for campaigns that are paused due to this.
