You don't have to send the same club pack to every member. The Post Club Run button only includes the members in the filtered list. So you can filter the list, post a club run, then change the filter and post a different club run.
A common example: members choose Red Wine or White Wine when they join. You post one club run of reds to the red wine members and a separate club run of whites to the white wine members.
Before you start
Preferences such as Red Wine and White Wine come from the club's product options. See "How to create a Fixed Release club".
Members with no preference won't be in either filtered list. Check for them with the No Preference option.
How to send a club run to some members
Go to Club Members.
Click Filters.
In Show memberships for, choose the club.
In with a preferred option of, choose the preference, for example Red Wine. The options are Any, No Preference and each preference set up on the club.
Use any other filters you need, for example and tagged as or with delivery method.
Check the list and the Post Club Run tile. Only these members will be included.
Click Post Club Run and set up the club run as usual. See "How to post a Fixed Release club run".
When that club run is posted, change with a preferred option of to the next preference, for example White Wine, and post the next club run.
What happens next
Each club run only charges the members who were in the filtered list when you clicked Post Club Run.
Troubleshooting
Some members weren't in any club run. They may have No Preference, or be paused, cancelled or still have an open club run. Filter with a preferred option of to No Preference to find members without a preference.
A member got two club packs. If a member is in both filtered lists, they'll be charged for both. Check your filters before you post. See "Why was a club member charged twice?".
