Don't contact Epic for any v1.25 stuff, the dudes (dudettes?) over at Epic only provided the "content" for Jazz Jackrabbit (e.g. sprites, tilesets). The engine was written by the former Orange Games dudes (now part of Lost Boys). So if you REALLY want to talk about v1.25 or whatever, you should talk to them. The only thing you should contact Epic for is (c)'s and (tm)'s. And for Lori the ever-so-rocking Dean, as mentioned.
Secondly, you should be able to get through to Epic using their webmaster e-mail addy. It worked for me lots of times.
Third, forget G.O.D., they're of no use to us.
Fourth, mass mailings? Bad idea. Instead, collect all the good ideas (see every respective thread on the board for those) and write up a well written document explaining IN DETAIL all the wishes and compliments/complaints. (I should have one lying around, I'll check my HD)

Yours,
