# Blacklists: How to Block People and Companies

> Never contact a person, an email domain or a whole company — for the workspace, one client, or one sequence.

A blacklisted person is never contacted. Enrolling them is refused, and a live enrollment ends as *suppressed* at the next step. Use it for competitors, existing customers, and anyone who has asked not to be contacted.

The page is **Settings → Blacklists**. Everyone can read it; Owners and Managers can edit.

<Info>
  **Nothing is deleted.** Blocking someone keeps the lead, their timeline and their conversation. You can still read the history and reply by hand. A blacklist decides what goes out automatically, not what you are allowed to remember.

## What you can block

| Kind                    | Blocks                                                   |
| ----------------------- | -------------------------------------------------------- |
| **Email domain**        | Every lead with an email at that domain                  |
| **Email address**       | One exact address                                        |
| **LinkedIn identifier** | One profile (the part after `linkedin.com/in/`)          |
| **Company**             | Everyone at that company, by name or LinkedIn company id |

Values are stored in lowercase. Domains have `http`, `www`, any path and a leading `@` removed, and full LinkedIn URLs are cut down to the identifier. Company names are matched loosely, so *Acme Inc.* and *Acme* match each other.

## Scope

Every entry has a scope, and the scope is part of the entry — the same domain can be blocked for one client and allowed for another.

| Scope               | Applies to                               |
| ------------------- | ---------------------------------------- |
| **Whole workspace** | Everything you do                        |
| **One client**      | Only that client's sequences and senders |
| **One sequence**    | Only that sequence                       |

**Client scope is the one agencies need.** It lets you block client A's customers and competitors without blocking them for client B.

## Adding entries

* **Add one** — choose the scope and kind, enter the value and an optional reason such as *existing customer*.
* **Bulk paste** — one value per line. With **Auto-detect per line**, anything containing `@` is an email, anything that looks like a host is a domain, and everything else is a LinkedIn identifier. Duplicates are ignored.
* **Upload a CSV** — one value per row, with optional `kind` and `reason` columns. Pick the client or sequence first if the entries are scoped.

## When it is checked

Twice, deliberately:

1. **At enrolment.** The [preview](/sequences/creating-managing-sequences/launch-and-enroll-leads) counts excluded leads and names the reason.
2. **At send time.** An entry added mid-campaign stops the lead at its **next** step, so you don't have to hunt down who is already in flight.

## Other ways people are excluded

* A single lead marked [**Do not contact**](/crm-lead-management/crm-features-use-cases/managing-leads#do-not-contact).
* Anyone who [unsubscribes](/email-management/email-deliverability#unsubscribe-link) from an email, across the whole workspace.
* Anyone who replied to any sender in the last 90 days, unless you include them on purpose.
* With [CRM sync](/integrations-api/crm-sync), your existing customers and open deals, kept up to date automatically and marked with the source `crm:<provider>`.

Entries added by the CRM are removed when they stop being customers. Entries you added by hand or by CSV are never touched by the sync.
