Especially awesome to get emails about a new version of an app you tried for 5 minutes 10 years ago and neither the name of the app nor the email subject or body gives even the slightest hint what the fuck that app does
1. Do not send incomprehensible emails to cold lists 2. If possible, remove people from your email list when they haven’t interacted with you in years 3. Unless you’re Coca-Cola, in any email you send there should be a one-liner to describe what your app or business does
@thomasfuchs not email, but I think @flydotio 's blog does an excellent job at this. There's a header in every entry that says something like "Hi, we're Fly and we do <thing>. We use <subject of blog post> to do <other thing>, read about it!"
