When creating basic filters, it is possible that the proposed groups do not meet your specific needs (e.g. members from previous years).
The solution is to create a list of temporary contacts.
For example, to send a newsletter to members from previous years, the best way would be to:
- Search the membership database for subscription dates corresponding to specific enrollment dates,
- Export the list of results,
- Import the list into your newsletter contacts,
- Send to a temporary contact list
