The addresses found in the header fields of an email message are not directly used by mail exchanges to deliver the message. An email message also contains a message envelope that contains the information for mail routing. While envelope and header addresses may be equal, forged email addresses are often seen in spam, phishing, and many other Internet-based scams. This has led to several initiatives which aim to make such forgeries easier to spot.
An example here is the rapidly growing trend of "inbox zero." It's actually known by a variety of names, but it refers to the practice of keeping your email inbox count at zero stored emails. Essentially, it's dealing with every email as it comes in and then deleting or archiving each one so that your inbox is always empty. This boils down to a fundamental shift in how users are utilizing their email inboxes.
It’s pretty much common knowledge that Gmail is awesome. It’s fast, connects seamlessly with the rest of your Google services such as Drive, has a cool app called Inbox, and is overall an extremely powerful email service. However, to use it with a custom domain, you need to purchase Google Apps for either $5 or $10/month, which for casual users is a bit unnecessary. On top of that, you don’t even get all of the features a personal account gets, e.g. Inbox.
