Which method is NOT used to add members to CRM campaigns?

The method of adding members to CRM campaigns that is not typically utilized is manual assignment. While it may seem intuitive, manual assignment doesn't leverage the automated capabilities or the strategic targeting that the other methods provide.

Using automation rules, for example, allows for dynamic and efficient addition of members based on predefined criteria or triggers. This means that a large group can be automatically included in a campaign based on their behaviors or statuses without requiring individual manual input.

Segmentation rules enhance this process further by categorizing members based on specific data segments or attributes, thus ensuring that only the most relevant contacts are targeted for particular campaigns.

Engagement programs are designed to facilitate ongoing interaction with a designated group of contacts, automatically adding them to campaigns as they engage with the content.

In contrast, manual assignment lacks scalability and may lead to inconsistencies, as it relies on human intervention, which can be prone to error and is not practical for large datasets. Therefore, it is the least effective method within the context of adding members to CRM campaigns.
