I could comment on any of the points above, but I’ll pick the last one. For fundraising I interpret this as writing a donor-centered letter. This seems to be particularly challenging for nonprofits to do for themselves (so immersed in the mission they struggle portraying an “outsider’s” perspective). But writing about what the donor is accomplishing; how indispensable they are; how they saved Billy’s life; how they put a roof over Molly’s head; and so forth makes such a difference in the tone and warmth of a letter.

It definitely stimulates response.
