Great IT related newsletter, helped us find a new ERP system and negotiate the price by more than 40%.
Mailing a tad too much I find but overall quality is helping my team.
B2B spam site affiliated with boiler-room style call spamming. Completely unsolicited and never honor opt-out demands. Avoid them or any company that uses them for lead generation.
Generates huge amounts of spam and cold call sales. Content for the charts and whitepapers is generally too old and out of date to be of trustworthy value.
I know that I never signed up with these people but I started getting "newsletters" from them. I unsubscribed but more "newsletters" came in. Their site stated that it took 48 hours to get off their list. How absurd. I blocked them. I wouldn't trust anybody that behaves in this manner.
