I have the feeling that newsletters are not something that we proactively search for. Indeed, the kw "best newsletter" only has around 600 searchs on Google per month.
I find that quite interesting, because newsletters content tends indeed to be much better* than "post content", but they are much "less searched".
*I am generalizing, I know, but there is way too much "seo focused" content out there today - and newsletters don't have that "tempotation": they are written for the user, not the bots).
Do you actively search for newsletters or do you just "find them by luck" and join if they resonate with you?
If you search for them, how?
I never actively search for newsletters.
I find new writers via references either on Twitter (from trusted sources) or by browsing online communities like IH, HN, Reddit.
I also find new newsletters when existing writers link to other articles/posts.
Hope that helps!
The thing is...
before Google (or yahoo, you get the point) existed, no one searched for webs either.
SEOs have fill the internet with "seo focused content" instead of content that's actually useful. Although Google has gotten much better at detecting good content, I think newsletter offers some insight that is hard to find on the "open web".
But...most of it is not searchable, because it's not indexed.
does it make sense to create a "search engine for newsletters"?
Definitely a fair point! Detecting quality newsletter with a search engine sounds like a fun but difficult problem. I think if taken too literally (like Google ranking), it doesn't capture the essence of quality writing and personality that shows up in the best newsletters. Also credibility of the writer is huge too.
I think it's a tough problem that might not have a big enough demand for it yet - but I could totally be wrong!
I'm sure you are already aware, but in case you aren't: there are some newsletter directories out there. I think tracking their success and demand might be a good indicator of the validity of your idea. https://bloggingguide.com/newsletter-directories/
"taken too literally (like Google ranking), it doesn't capture the essence of quality writing" - Agree!
I am aware of newsletter directories, but somehow they don't get "searched for" either. The demand for newsletters is there (newsletter based business models are growing as is software specifically created for them) but there is no "search intent".
I guess the user searches for what she/he is looking specifically, not for a whole "newsletter" to join (even if he/she joins it after the reading!).
I don't think I've ever heard of people actively searching for newsletters, so I'd also be interested in hearing an answer to the question 'how'.
I'm in what's probably the bulk of humanity: if I'm already looking at something I deem valuable and want to know more about that topic, I'll subscribe.
Actually, these days my pain point is unsubscribing from all of these newsletters that I no longer need. I'd appreciate a tool that could let you look at a list of your subscriptions and unsubscribe to a bunch of them all at once.
