# Suppressions

People and companies on the do-not-contact list.

## What a suppression is

A suppression is a do-not-contact rule for a person or a company. Add a lead or a company domain, pick a reason, and optionally a note and an expiry.

## How campaigns use them

Campaigns skip people and companies on this list. Some reasons are hard and cannot be overridden. A campaign can be allowed to bypass soft reasons, and can also skip people contacted recently or who never replied, using its suppression policy.

## Checking

You can check identities against the list before you contact them.
