Wow, is that you're only beef with sending email? You didn't touch on the nightmare of the various authentication methods, using SSL or setting up SMTP relay hubs. There's the minor annoyance of attaching "HTML" email bits to a message, but that's a minor barb. Hell, even if you do this dance right, the mail will often get stuck in a spam trap or not get to the addressee for a long time due the way ISPs batch SMTP traffic. And what if your ISP gets on some stupid spammer black list? You may not have done anything wrong, but some idiot on your domain did once and now you get to pay the price. Seriously, I cringe every time I'm asked to add "email notification" to an app. It's a disaster.
