I like how easy it is to send out mass emails or group notes. It's also nice because it saves time since I don't have to go through all my email looking for specific people just so I can say "Happy birthday." Sometimes I forget who it goes to sometimes but other than that its really convenient. The only thing I dislike about it is when I'm sending an email with multiple recipients there aren't any tabs at the bottom where I could put them. Maybe add some? But overall I love using this service! Sending Christmas Cards has been made much easier!
