How to best deploy an email forwarding library

Question

I wrote a .NET library that automatically forward some emails for a newsletter but am unsure as what the best way to deploy it is.

Ideally, I'd like an easy way to monitor its state for whenever the service either stopped working or the certificates expired, etc.

The most braindead way I could think of would be to wrap it up in a window scheduled task and send daily emails to an admin just to notify that the service is still running and report some eventual errors that were detected.
