I don't really care about putting my main account at risk, since I have pretty well retired it: too much time to get too little. I wouldn't mind getting the UA miles, though. So, should I think it's worth it, using a different e-mail than my other MyPoints? Should the e-mail match the one on file with UA? Previously I had MyPoints go to a "likely-spam" addy, while UA goes to my work. Can I join MyPoints and decline their clickthru mails from the beginning, just getting a welcome at my work addy? Or, I have a new ISP and was thinking of using their mail for reputable commercial mail; maybe put both programs on that? I have an uncommon name and recently moved to a new ZIP code in the same city; I don't think MyPoints knows about it. I see that on the first signup page, my e-mail and ZIP would be different from what they have; do they ask for more details on later pages?
