When you’re composing a new message or a reply, you can insert anyone’s email address in the body by entering the @ symbol, followed by their name. For example, @Abhimanyu will bring up a list of people in your contact list with that name, and choosing any of them will add a mailto link labeled with their name. When your recipient clicks that link, it’ll bring up a new compose window so they can write to that contact.
If you mention someone with a + sign instead of the @ symbol, that contact will automatically be added as a recipient of your current message. It’s a nice touch that makes it a little easier to get your emails right – similar to how Gmail reminds you to attach a file when you mention that you’re doing so in your email, and don’t have anything attached.
