I used to get a lot of emails from Omics a few years ago. Pure cold-calls advertising conferences where I could present my world-leading research in areas where I had done no work. The fever has thankfully subsided.

Nature Group is not without criticism here, either. Still one of the crown-jewels of research publications. I used to subscribe to Nature but dropped it due to their limited archive, the proliferation of their specialty journals (separate subscription required), and the high amount of sponsored content.

Still subscribe to Science Magazine which makes its full archive available and doesn't have as many spinoffs.
