Suppressions

The suppression list is an automated safeguard that helps maintain your email list hygiene and protect your sender reputation. When using OneSignal as your email service provider, this feature automatically manages problematic email addresses to prevent deliverability issues. More on email deliverability

How It Works

When OneSignal detects any of the following conditions:

1. An email recipient marks your message as spam
2. An email address has previously bounced

The system automatically adds these email addresses to your suppression list. Once an address is suppressed, OneSignal will no longer attempt to send emails to it, helping to:

1. Maintain a clean email list
2. Improve overall deliverability
3. Protect your sender reputation
4. Reduce bounce rates

Managing Your Suppression List

You can view and manage your suppression list by navigating to Settings > Email > Suppression

Note:If you are using another ESP as your email service provider, your suppression list must be managed directly through your ESP's platform.
