This program is currently designed so the email addresses are set when the cron or daemon commands are called. Anyways, I think it would be nice to redesign it in a way that allows different feeds to notify different email addresses, what do you think?

The easiest way to do this is to add a feed option which allows setting email addresses and which behaves like the template option (if it isn't set, then the default emails are used), although it might not be the best solution.

As a side note: thank you very much for developing this! :)) Now that Feedburner is deprecating email notifications, I started using your program via Docker and it's working great as a replacement! I love that it's very lightweight (go is awesome hehe).

I'll leave the template I created and use so the notifications are similar to the ones by Feedburner: https://gist.github.com/avm99963/14f81a255c6f8192c7cb420bfd86fd21
