@numericcitizen No, I know they are comparable, but the only thing I really liked about Hey was that I could sign up to a load of newsletters and just read them when I wanted. I found the Feed experience pretty poor, however. You had to keep pressing a button to expand the email, and it just started getting clogged and hard to read.
Everything beyond the newsletter experience wasn't ideal either. I think I couldn't get used to the 'let it flow' approach. It was just diluting the search function.
I was considering using Mailbrew just to cover my newsletters coming into my inbox. Outside of this, my email usage is very light and Hey wasn't really solving any issues, only making it harder to read and manage the emails I did need.
