Send an e-mail after finishing

[Hoempi]

As a user of Bragibooks I would like to get an e-mail when conversion has finished.

After submitting the ASINs the process might take quite some time, depending on the amounts of books to create and their respective durations. Due to various reasons it may happen, that the browser tab is not still open, when the process finishes. Therefore I would like to be able to provide credentials for a SMTP server which Bragibooks would use to send a copy of the "Confirm" page upon finalization of the pipeline.

The e-mail could be plain text, to keep formatting easier. Or, could just list the ASINs and which of those finished with or without errors,

Id love a discord notification. I'm sure there are other methods people would like to be notified too.
