Show HN: Free tool to convert newsletters to RSS feeds

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.

Similar tools exist already, the most well-known one is killthenewsletter, but imo it’s always good to have alternatives.

You can try it out here: https://lighthouseapp.io/tools/newsletter-to-rss

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.
