Yes, donors can give anonymously. On every “Make Your Donation” form in the Giving Basket, donors can choose which details to share with the nonprofit(s) to which they are donating: their name, email address and/or mailing address. While this blocks nonprofits from receiving any information donors choose to keep anonymous, these details must be provided on the donation form, and both Charity Navigator and Give Lively will retain them in order to run the Giving Basket.
