I'm curious. No one has asked the important question. Are these newsletters written by who? Or copy pasted with some rewording like 99% of the newsletters out there? Don't bash me, but I had to ask.
Great question which gives me an opportunity to explain the product and development in greater detail.
The writing is not done by me as I got someone who is a far greater writer than I. They are a computer technician who does a fair bit of sales copy writing work.
It took me a long time to find the perfect writer for these newsletters as techies tend to be more technically minded, and writers tend to be more creative minded. I had to find someone in the middle. The awesome thing about this writer is that they are also SALES copy writer, they know how to write to CONVERT.
In sales copy writing, you need to initally grab attention, hold it so they read the entire article, educate them on the dangers/need/wants and then subtlely let them know that if they need someone to setup-this-backup/protect-from-ransomware etc.. you can help.
I surveyed my past Technibble customers asking them a variety of questions including "What do you want to educate your customer about?". I chose the best topics out of those, spoke to the writer about the direction I want to go with it and they did the rest.
During the development I studied the optimial tone, the optimal length and the optimial frequency. I also spent a lot of time experimenting with optimal layouts (especially for the print version. What fonts are best for reading in print, what layouts, how does it look in black and white etc..).
As someone with a site like Technibble and a large readership/subscribership, I have this kind of data because I optimize Technibble content in the same way and have been doing it since 2006
There are other services out there, there are others that "reword like 99% of the newsletters out there". These are different. They are written by someone who knows how to write to convert, with the research/formed/designed by me, someone with 10 years experience in getting people to read my newsletters.
