# Do not contact

> Block email addresses and whole domains so Guhan never messages them, and see what happens to people already in flight.

The **Do-Not-Contact (DNC)** list is your workspace's block list. Anyone who matches an entry is never added to a List, and anyone already in a sequence is stopped.

## What you can block

| Entry | Example | Blocks |
| - | - | - |
| **Email address** | `bo@example.com` | That exact address |
| **Domain** | `acme.com` | Any email address at that domain |

Those are the only two kinds. There's no block for a LinkedIn profile URL or a phone number, so to keep someone out you block their email address or their company's domain.

> [!TIP]
>
> Add your own company's domain so Guhan never reaches out to your own team.

## Add entries

**1. Open the list**

Go to **Settings → Do-Not-Contact list**.

**2. Paste entries**

Put one email address or domain on each line. Entries are lowercased and trimmed, and adding one that already exists is harmless. Lines that aren't a valid email or domain are rejected and listed so you can fix them.

**3. Add to list**

Choose **Add to list**. You can search existing entries from the same page.

## Block a company

On the **Companies** page or a company's detail page, choose **Block**. This adds the company's domain to the DNC list and marks the company as blocked, together in one step.

Unblocking a company doesn't remove its domain from the DNC list. Remove the entry on the DNC page if you want it gone.

## What happens when you add an entry

Adding an entry takes effect right away, including on people already in your workspace:

* **Prospects already in sequences** that match are paused and won't receive further messages.
* **Matching prospects in your Lists** are marked as unsubscribed.
* **New prospects** that match are rejected before they are added to a List.

## Removing an entry

Removing an entry doesn't bring anyone back. Prospects who were paused stay paused, and prospects marked as unsubscribed stay that way. To re-engage someone, add them back to a List and enroll them in a Campaign yourself.

## Good to know

* DNC is per workspace. Blocking `acme.com` in one workspace doesn't block it in another.
* You can add up to 500 entries at a time.
* There's no import or export; entries are added by pasting.

## If something's off

* **A blocked person still got a message.** Check that the entry matches the address they were sent to. An entry for a person's work email doesn't cover a different address of theirs.
* **I can't see the DNC page.** The Settings row is shown to admins. See [Roles and permissions](https://docs.outzen.ai/workspace-settings/roles-and-permissions.md).
