I don't always use the email replies but, I've noticed that when I do, people on the receiving end respond better. I definitely recommend this thing. It doesn't make a bunch of draft replies to all emails like fyxer or some of the others. Instead, to keep your usage lower since it is metered, when you open an email to reply, it begins writing the reply and integrates all relevant info from all of your other emails with them. It's great and it's worth snatching up a lifetime deal for the speed and quality of the replies - emails a huge time suck so it's worth the money.
