I have a feeling LinkedIn is the new spam abuser. I have no direct proof (it could be me signing up to a shady conference / email list) but the moment I got a new company email address and a co-founder title, the floodgates got opened, I get 4-5 "handcrafted" (automated to look like ones) emails plus the "following up to make sure you got my email" or "bringing it up your mailbox", most have no unsubscribe links and have a "let us know if you don't want to hear from us again". From legal services, graphic design, off shore hiring / staff augmentation, financial services. I get it that people need to sell to stay in business, so does my company, but it's starting to be a nuisance, especially since it many times passes the spam filters, and each email gets 2-3 "just following up" emails.
