eCards for charity website?

I represent a Canadian charity organization. My organization wishes to have an ecard WordPress plugin feature that can allow donors/users to send free ecards, as they donate to a specific cause to various people, via email. We want to have base template (with photos and text) on the ecards and then allow the user to only specify/manipulate the text that will be written on the ecard (limited user accessibility). However, we also want the user to be able to choose the specific ecard, and background colour, and whatnot if applicable. So my big question is, would this plugin be a practical use for a charity organization and would, what I specified, work with this plugin? Let me know, thank you in advance.
