Here are a few recommendations when changing your list settings so you don’t inadvertently remove people from one of your lists.
Adjusting age or birthdate ranges
For example, if you had a 0-1yr and a 1-2yr list and you wanted to change it to 0-6m and 6-24m.
- Make all changes in one edit session.
- Make sure the entire range is covered in your new lists. For example, if your max age was 5y, and your new set of lists has a max age of 4y, everyone who was 4-5y will be removed from a list.
Converting age or birthdate based lists to manual
- Step 1 – Merge all lists into a single age/birthdate list that covers the entire age range, and save the change. e.g. If your youngest list has a min age of 0y and your oldest list has a max age of 5y, create a single list with a min age of 0y and a max age of 5y.
- Step 2 – Now that all people are on a single list, edit the list again and change the Placement to Manual
