I like that this service allows for me to receive emails from people who want my business! The price was very reasonable too which makes it even better! Sometimes when you receive messages through other services sometimes they are not in your inbox immediately so this may be useful to have as well if there's some delay between receiving their message and having them show up here (or vice versa).
This has made our lives easier because we can now start communicating with eachother without sending individual mails back and forth or waiting days/weeks until all of us hear what everyone else had said before deciding whether or not to respond.
