I created a small free tool that gives you an email address, and every email that’s sent to it is added to the resulting RSS feed.<p>Similar tools exist already, the most well-known one is killthenewsletter, but imo it’s always good to have alternatives.<p>You can try it out here: <a href="https://lighthouseapp.io/tools/newsletter-to-rss" rel="nofollow">https://lighthouseapp.io/tools/newsletter-to-rss</a><p>I tried to keep the time until an email shows up in the feed as low as possible. In my tests emails arrived at the inbox about 10-20 seconds after they’re sent, and then processing takes ~30s, usually it’s faster. The file is cached for 1min. So the maximum time until an email shows up in the feed should be 2min.
