Tribute Gifts are in a class by themselves when it comes to fundraising. They can require a bit more management than "general" gifts, but they can also offer you the opportunity to acquire new donors that might otherwise not be involved with your organization. They also offer existing donors the opportunity to show their respects by giving to a cause they already deem worthy.
Tributes can be made for people or pets, a fact to which many animal-oriented nonprofits will attest. Tributes to the living are the "in honor of" kinds of gifts, while tributes to the deceased are the "in memory of" gifts. "In honor" of gifts may be motivated by an event such as a wedding, anniversary, birthday, graduation, or other important moment for congratulations.
