Just a word from a guy who has worked on the admin side of spam filters. Look through your spam folder in your email whatever (webmail, Outlook, Thunderbird, etc). Look at the subject lines. Avoid using anything in your subject line that resembles anything you see there, and you should be OK. You're not writing something that is going to look like you're trying to sell something or pass yourself off as a prince of a random African country or head of some random US federal body, so the ones that filter the body of the email, too, should let you through. Don't put the game name in the subject line, or they will trigger the filter after too many. Don't use something generic, like "A Plea," "Don't Do This," or "Save Our Game." Mix it up.
Obviously, yes, they're going to have something a little more robust than an entry-level Barracuda, but we can keep them from being automatically deleted by the spam filter if we're judicious and creative. That doesn't stop them from being manually deleted, but the executives will know we're doing it, even if they don't read a single one.
I'm against this, too, but I'm going to do it. I trust Tony and his team, and all of you, for that matter, or I wouldn't be here.
