Somewhat inspired by rss2email, I decided to build forlater -- a bookmarking/read-later service you can use via email. Send a link to save@forlater.email (subject doesn't matter!), and get a readable version of it in your inbox. Email is especially useful here because you can organize it however you like, and gives the you -- the user -- full control of your data, no account required.
I've been dogfooding it, and it's super handy. Here's what a saved page looks like on FairEmail (Android): https://x.icyphox.sh/B8J4o.jpg
Getting the HTML email template was surprisingly hard. You have to write HTML like it's 1999: <table>s and inline styling. For plaintext, I'm using the oh-so-handy 'lynx'.
Finally, it's all free software: https://github.com/forlater-email (or https://git.icyphox.sh/forlater)
Rest assured, you can be sure that forlater isn't going anywhere. It costs me very little (for now) to run, and I'm its biggest user. I plan to make it more self-hosting friendly and write some docs for the same.
Until then, thanks for checking it out!
