It's perfectly fine to ignore 99.999% of those. Whip out a script or an app that does exactly what you need without the bloat if viable.

I subscribe to many newsletters and get loads of offers. I pretty much ignore all of them. Most of those $10/month tools are just clones of something or not useful at all in the trenches so to speak.

Do you subscribe to any paid newsletters? If so, which? (If you don’t mind sharing)
