Blocklist - Overview and Usage

CleverReach has blocklist functions that allow you to block email addresses or domains in general. All entries on the blocklist are automatically ignored or deleted during imports and mailings. There are a total of two different blocklists in our CleverReach environment:

Blocklist - What does the term mean?

In the email marketing world, blocklist (or blocklist, denial list) is used to refer to a list of IP addresses, domains, email addresses, or other identifiers that have been identified as sources of spam, malicious activity, or unwanted content.

If you blocklist an email address in our email marketing tool, any email communication with that address will be blocked or moved to the spam folder to prevent unsolicited emails from being sent to that address.

The use of blocklists is a common way to reduce spam, increase security and combat unwanted activity by excluding potentially problematic items from our system.

Global (cross-list) blocklist

Via Recipients > Blocklist you can find the global blocklist. All entries are taken into account here across all lists. This means that this recipient list is compared with all other lists before each import/mailing.

How to search, add or delete recipients you can read in this article.

List specific blocklist

The same function is also available for specific lists. Within the list, you can store list-specific entries under Settings > Blocklist. These entries apply exclusively to this recipient list. Addresses in other recipient lists remain unaffected.

Enter here the addresses or domains to be specifically blocked for this recipient list and click Save.

Important notes:

  1. Entries within the blocklist will always be considered accordingly. Before every import or mailing a check against the blocklist happens.
  2. Entries on the blocklist will automatically be deleted by the system of import / distribution for performance reasons.
  3. You can also work with placeholders, e.g. if you need to block entire domains. Just create an entry as e.g. *
  4. Blocklist entries can be made automatically through feedback loops (e.g. with Hotmail or AOL). Whenever a contact marks one of your emails as spam those contacts can automatically be added to the blocklist.
