# Suppressions

> Understand how suppression rules protect recipients from unwanted email delivery.

Suppressions prevent email from being sent to addresses that should no longer receive mail.

They are evaluated separately from segments and topic preferences, so a contact can be selected for an audience and still be excluded from delivery.

## Suppression origins

Dugble tracks why an address is suppressed. The current origins are:

* `bounce` — the address was suppressed after a delivery failure.
* `complaint` — the address was suppressed after a complaint signal.
* `manual` — the address was added directly by your team.

## Suppressions override targeting

Segments answer who you want to target. Topics and subscriptions answer what a contact wants to receive. Suppressions answer whether an email address should be attempted at all.

Because of that, suppression status can make a recipient ineligible even when segment membership and topic preference would otherwise allow the message.

## Suppression and unsubscribe are different

A contact's `unsubscribed` state is a recipient preference stored on the contact. A suppression is a delivery restriction associated with the email address.

Treat them as separate signals and preserve both when they are relevant to your application.
