If I want to subscribe to a blog and it doesn't have a web feed (RSS/Atom), I normally just forget about. Add web feeds!!
However today I really wanted to follow one of such blogs. Luckily I found https://kill-the-newsletter.com (first link I found), which seems to work quite well. Maybe it can help you out as well if you are ever on the same position :)
@ob You should talk to the site owner and ask them to provide a web feed as well. :)
Going around the problem with "email newsletters-to-web feeds"-services is only a short-term solution.
