Try sending some emails to multiple recipients using ACTION_SENDTO and a properly crafted URI. Watch the SMS app show on some phones when using Intent.createChooser and totally misinterpret the intent to the astonishment of the user. You wouldn't see this problem if you didn't test on a LOT of phones. It's not immediately obvious. I've been developing for Android for a while now.
