Haskell Weekly in 2018

by Taylor Fausak on

I run Haskell Weekly, a free weekly email newsletter about the Haskell programming language. At the end of each year I reflect on how things went. Here’s a look at Haskell Weekly in 2018, including popular links, the state of Haskell survey, and subscriber statistics. You may be interested in comparing this post with Haskell Weekly in 2017 from last year.

Haskell Weekly published the second annual state of Haskell survey in 2018. To the more than 1,300 people that filled it out: Thank you! Your feedback is valuable for improving the state of Haskell. If you’re interested in the results, please read the 2018 state of Haskell survey results.

Haskell Weekly subscribers in 2018

At the start of the year, 2,110 people subscribed to Haskell Weekly. Every week about 17 people subscribed on average. At the end of the year, 3,002 people were subscribed. Compared to 2017, the rate of new subscribers has slowed a bit. That being said, I am thrilled to continue to grow my audience without doing any real marketing our outreach.

Open rate

This graph shows the open rate of Haskell Weekly subscribers in 2018:

Haskell Weekly open rate in 2018

The open rate stayed relatively constant around 52%, going as low as 49% and as high as 55%. In 2017 the open rate was trending downward, so I’m happy to see it stay mostly flat over the course of the year.

Click rate

The click rate stayed relatively constant around 24%, going as low as 20% and as high as 28%. Like the open rate, I expected the click rate to continue to fall. I was pleasantly surprised to see it stay about the same instead.
