I get them to, but thankfully they get caught by my Google Spam filter and avoid my inbox. I already get 100 emails a day from clients and projects I'm working on and the last thing I need is an email promoting the same vendor I have no desire to hear from 1000+ times a week.
I've never really looked, but their should be a "Unsubscribe" option somewhere on those emails to stop them if you don't want them. If there is not, Transworld is violating email spam laws that could cost them being fined I believe.
Otherwise, I would simply send recommended that everyone simply keep emailing Jen's from TransWorld and any other TransWorld email address till you find out how to have your email removed from the spam list. Tell them you don't appreciate being spammed all the time, which is kinda appropriate as they are trying to sell everyones email for profit.
But there should be a "Opt out" option instructions included in the email somewhere.
