How do we add subscribers to Suppression List?

Subscribers Are Added To Suppression List Using Automated & Manual Methods

As part of Ampliz Suppression service, we auto-suppress email subscribers under security parameters like Spam & Abuse Complaints. After you upload Your Data, we auto-match it against our in-house database, send permission requests, delete opt-out responders, and isolate out-of-use email addresses. Ampliz ensures clean and accurate Email Append for your customer database.


By adding email addresses manually, we ensure that subscribers marked in your database as 'do-not-mail' are not added to the list inaccurately by any external system. To suppress manually, you need to add subscribers based on email address ( and domain (

To add or remove subscribers from the suppression list, we follow a few steps:

Due to security reasons, email addresses cannot be removed from the suppression list. Following are the four criteria by which the subscribers are added automatically to the email suppression:

1. Spam:

When a subscriber marks one of your emails under spam category, the email address is automatically added to the suppression list.

2. Unsubscribe:

When a subscriber does not wish to receive any emails from your company in future, they click on to the [UNSUBSCRIBE] button and unsubscribe from the email list. Once they click on ‘unsubscribe’, requesting the link, their status is automatically changed to ‘unsubscribed’ through your email list account and added to the Suppressed List.

3. Abuse Complaint:

For subscribers who have reported one of your emails as 'Abuse', the email addresses are automatically marked and transferred to the campaign database.

4. Bounce Rate:

When a subscriber’s email address returns a series of soft bounces, it's automatically marked as hard bounce and thus, automatically added to the Suppression List.
