You might already use auto email sequences to communicate with your subscriber. The way it’s being done is preprogrammed. You send the emails at a certain pace, regardless of when and if at all they read them. That is not optimal.
At the end of each email have a call to action asking them to help you with just one click, something like: “Did you find this email message useful or enjoyable? Help me by simply clicking YES or NO.” The click will tell you two things: 1. They finished reading it. 2. If they liked it. You can use both to dynamically trigger the next email and also decide which email to trigger based on their reply.
You as a marketer would like to know more about the consumption of your product.
A PDF reader app that the client gets for free with the PDF file you send them or they download. They can, of course, open the PDF file in any other app, but you incentive them to use your app by promising them real time up to date data, surprises, etc. The app has two primary functions:
1. Report to you their consumption of the PDF file (how often, how far they read etc.)
2. A real time communication device that adapts to how they interact with the PDF document (where they currently are, what have they already read, etc.)
You would like to know if your buyer does use the product you sold them and how often.
Have a “sticker” or “button” that you ask them to stick to the product they bought, and a smartphone app or the device can connect to a home wifi network directly (you can offer an incentive like a discount.) You explain to them that data is anonymized, and it will help you create better products for them in the future.
Whenever they use the product (make coffee with their new machine) or consume it (read the book to their child) they “activate” the sticker. They do so by waving their smartphone near it, or pressing a small button on the sticker), and you’ll get the data through their smartphone or directly through their home wifi.
