Low value, high frequency
These guys send lots of low-value information imho. It's a blend of actual news and scammy come-ons like this email subject: "PS: A Nobel-prize winning discovery has many people raving about this ‘sunscreen in a pill’ - see what it is by clicking here now." This may be of value to you or to their core audience. I think it's low value and a poor business model.
