Sorry I'm not sure what you mean. One of us emailing something for you is essentially the same as you emailing it from a new email address that doesn't identify you. You can create a number of these if you like (2, 3) as well as new anonymous Skype accounts to give them if you're worried that somebody on the other side can identify you from your email and tamper with it, and want to contact them from emails not associated with you.
If you're worried that all emails are being tampered with on their side, that's a much bigger issue and probably much less likely too. if that happened to any organisation it's a pretty serious issue, so unless you have reason to believe that they are essentially non-functioning as an organisation (since they are supposed to help people in your situation), then I'd give them the benefit of the doubt that emails are working. It would also not be made better by someone else double-emailing it on your behalf. Or really, it wouldn't be worth contacting if you believe they're non-functioning.
Does that make sense? Sorry if I have oversimplified anything, especially as I'm not very familiar with RA situations, but I hope you're seeking help in a grounded way and not either be too frightened or expect too much from what an overseas organisation can do for you.
