 [Buttondown](https://buttondown.com) is an email platform, similar to the now-defunct [TinyLetter](https://buttondown.com/comparisons/tinyletter), that allows you to send emails to subscribers. It also has integrations with many other platforms to automatically publish or add subscribers, amongst other possibilities.
