I have long been a believer in the superpower of specificity, and here is another example that shows it in action.
Rather than asking for generic donations to "help the animals", Zoo New England created an Amazon Wish List with specific requests to fulfill their needs. You can find out that gorillas enjoy tea, but need the caffeine-free option or that chinchillas need a treadmill, or that some animals are on so many pills, they need a pill organizer! You can select the price range, type of item or animal that you'd like to help.
Could you use the Amazon Wish List concept for your organization? Certainly there are needs you have, and if you can find a way to make them specific enough, perhaps it will align with this format. It may be a great way to have your wishes fulfilled.
