I have tried the e-mail route. Inevitably what happens is that the person gives me a phone number and tells me to call them :|
I'm not entirely sure what it is about making phone calls that is so overwhelmingly scary. It used to be the case that getting up out of my cube and going to talk to ... anyone ... was just as scary, but I've been able to overcome that. I think its because I'm afraid I'll loose what it is I need to ask from my head, because I'm afraid I won't be able to understand the person on the other end of the phone, because I can't be quiet with someone on the phone. That is, I can't nod and expect them to see it. I have to worry about who might be in earshot of me. Most of my calls I have to make from work (that's when people are available to talk), I can go outside with my cell, but still.
