# How do I set up an email blocklist for email contact suggestions?

## The Email blocklist lets you specify which email addresses and domains should be excluded from contact suggestions. This keeps snapAddy DataAgents focused on relevant contacts and helps protect your CRM from unwanted entries.

### What is blocked automatically?

snapAddy automatically blocks certain email addresses and domains by default. This list is continuously maintained and updated in the background — it cannot be edited by individual users or administrators.

The following entries are **excluded** automatically:

- Generic email addresses such as  **info@, office@,** or **newsletter addresses** are detected and skipped by the parsing algorithm.
- Emails **without signature data**, as well as **potential spam** or **phishing messages**, are not analyzed at all.

This multi-layered filtering is one of the reasons why snapAddy DataAgents is recognized as one of the most accurate solutions for automated contact enrichment on the market.

### What should you add to your own blocklist?

In addition to the automatic filters, we recommend adding the following entries to your organization's blocklist:

- **Your own company domain**, to prevent internal emails from being analyzed.
- **Domains of suppliers, service providers, or regular business partners** with whom you communicate frequently. This prevents DataAgents from being flooded with contact data that does not need to be added to or updated in your CRM.

### How to set up the blocklist

1. Click **DataAgents** in the top navigation bar.
2. Select **Settings** from the left sidebar.
3. On the *Organization-wide Settings* page, scroll down to the **[Email blocklist](https://app.snapaddy.com/settings/email-blacklist)** section.
4. Click the **Add email/domain** button on the right.

5. Enter the email address or domain you want to exclude and confirm your entry.

The listed addresses and domains will be ignored by the parsing algorithm from that point on. Existing entries can be found through the search field and edited or removed from the dashboard at any time.

### Input formats

You can block both individual email addresses and entire domains:

- Single address: `name@company.com`
- Entire domain via wildcard: `*@company.com`

### Note for administrators

The blocklist applies to your entire organization. Any change therefore affects all users in your snapAddy organization. We recommend coordinating updates with your team to ensure consistent data quality.
