Tech Republic accoutn questions

1) i get approx forty-eleven emails a day from TR. is there a pref someplace where i can opt out of some of it? I don’t want to spam it cuz then i may miss admin or webmaster emails that matter.

2) i have a 2nd account that i signed up for (cuz i forgot i had an older one) and don’t need. can it be deleted or deactivated or something? cuz it’s spamming a 2ndary email.
