Last weekend I got fed up with all clicking the “unsubscribe” button on all the newsletters in my Gmail inbox, so I went looking for a way to automate it. I found some scammy apps like unroll-dot-me that sell your info and barely work. I also found a free Google Sheet script from 2017, but it crashed on the first message in my inbox. So, I rewrote it – and now it (seems to) work great!
