Using an email and notification system

From a desktop app (Windows or OS X), do any of you have any experience using reliable email sending services like SendGrid? I want to use something that will make it easy to communicate with others from my app without the end-user having to configure a local mail client so that SMTP works.

Also, any experience making it simple to use the simple notification system that is built-in to the OS (Windows 8 and OS X)?

macoslib has the notification stuff for Mac OS X…

You could always run your own SMTP server and your software could use that…

thanks, Shao! Macoslib sounds interesting.

NSUserNotifications is what you want on the Mac, not to be confused NSNotifications, similar names, similar functions, but two different purposes.

As for Windows, AFAIK, you need to roll your own or look for a third party toolkit.
