Reached 200 subscribers

On 11 February 2018 I sent my first book update to the subscribers from the book landing page. This was not only a first book update, but a first e-mail campaign I ever sent.

I sent it to first 92 people. I got my first subscriber (that was not me nor my brother) on 27 September 2018. It took me exactly 159 days until I reached 100 subscribers on 4 March 2019.

It took me another 334 days to reach 100 more subscribers. 493 days in total which is roughly 1.35 years. So far I sent 3 updates and the next update will go to more than 200 email boxes!
