There are use cases where you want to update a segment of your users. For example:
- remove a tag from all users who purchased in the last 10 days
- set a value for email preferences for people who did not open recent emails
- move email recipients from a list to another.
Steps to update recipients:
- Create a segment with recipients according to your conditions
- Export segment (email only is needed)
- Import segment and configure new attributes accordingly.
