I have two DCH-S160 water detectors it allows me to get a notification on my phone if there is water detected but not send email on a water detection event. (don't always have my phone with me or on) I tried the ITTT Iphone app and found that it integrates Dlink and other home automation. It allows me to set up a rule that sends me an email when water is detected. It can also call a phone number when water is detected.
I suggest you take a look
