Activation: A new user creates an account but, they do not use your product within the first 7 days. Create an  “activation” campaign that sends an automated email with their login information, steps on how they can get started and include a video demonstration for additional support. You can also invite them to a one-on-one meeting to walk them through the product and answer any questions they may have.
This article is by far one of the most interesting and fun articles that I have read in a long time. I say fun because the points mentioned here are simple and easy to read. They are not long passages that speak a lot and tends to lose focus. On the contrary the points mentioned here were in short crisp sentences that did not bore me but made my read a pleasurable one. Thanks!
