With the frequent emergence and growth of new, lucrative social media such as Snapchat, Twitter, and Instagram (the #trifecta), combined with the existing ease of communications platforms like text-messaging, it tends to become more and more difficult to grasp the attention of the reader through old school email. One of the few existing grandfather media, where your inbox still remains private, your email gets flooded every day with Spam, work messages, subscription check-ins and other various, undulating updates.

Stewart Butterfield, CEO of real-time messaging platform Slack, suspects that about 80% of your email inbox is not coming from an actual person, and not even including Spam. “Here’s your Uber ride receipt, someone’s following you on Twitter, marketing newsletters,” and so forth, he said. Because of this, people usually skim down their inboxes, ignoring those emails that don’t seem relevant or interesting.
