# Subscriptions & Suppression

Subscriptions & Suppression brings together how contacts join your audience and how they are stopped from receiving messages: opt-in and opt-out (subscription), system-driven deactivation, and manual blacklists and Robinson lists.

---

## What This Covers

- **Subscription** – how contacts opt in (including [double opt-in](/v1/docs/set-up-double-opt-in-with-the-email-channel)) and opt out.
- **Contact Deactivation** – automatic suppression based on deliverability (bounces, spam complaints), and reactivation. See [How Contact Deactivation Works](/v1/docs/deactivation-basics).
- **Blacklists and Robinson Lists** – manual and list-based suppression. See [Blacklist Management](/v1/docs/blacklists-basics) and [Robinson Lists](/v1/docs/robinson-lists).

## Start Here
