What's the betting that this is a scam?
The gaudy pink box on this screengrab shows the reply-to address is using gmail, not Redcross.org as in the (presumably spoofed) email sender's details. If this was a legitimate request for funds from the Red Cross (or is it Organizing for Action?), why wouldn't they use their own corporate email address? My guess is that the 'instructions' that will evidently be given to you if you reply to the message will (a) be malware infected and/or (b) be phishing for credentials or seeking advance fees. I, for one, am not about to find out.
The only surprising thing about this incident is that I am still surprised that scumbag scammers are yet again picking up on a tragic news story as a lure for gullible victims. They've done it many times before, and no doubt will do it again.
[If by some miracle I am wildly mistaken, and this is in fact a genuine begging email from the Red Cross, or indeed Organizing for Action, we need to talk while I eat my hat!]
