Email subscription works by sending an email containing my blog's RSS feed address (https://kenregum.bearblog.dev/rss/) in the body (not the subject) to add@rssby.email. This link automates this for you. All you have to do is to click send. If you are an iOS user experiencing problems (i.e., you have disabled or are not using the default Mail app) and have Gmail, you can click this link instead.
To unsubscribe, send my feed address (https://kenregum.bearblog.dev/rss/) to unsubscribe@rssby.email. This link (and again, for iOS users experiencing problems and have Gmail, this link) automates this for you.

Thank you!
