How is it I didn't get that alert?

I too got this email notification but luckily I don't have any of those coins in my account.

You got or you didn't? "too" and "got" seems to contradict in your statement.
I have not receive an email notification about wallet removal same as @buwaytress, but I believe all users should have been notified regardless if they have those coins in their account or not.

Yeah, I was saying I
never got any notifications from Bittrex, ever, about wallet removals. As I stated, I've only been affected once when they delisted 1stblood, and I only found out about it when I was just doing manual spring cleaning, the wallet icon had an alert next to it (exclamation mark) and only after hovering over it did I see it was about to be delisted. Sold it all off 4 days before the deadline.
Who would be willing to hold those scamcoins anyhow? It looks like Bittrex is really doing you a favor by encouraging you to let them go lol.
Since when do exchanges do us any favours? They list coins for a huge fee, so if you think about it, they're doing the community a huge disservice by listing those damned coins who can afford to pay.
