> Algorithms with Go is free, but you need to provide a working email address to gain access. I won't spam you and unsubscribing is very easy.
Why? Why should someone provide an email address? A line or two describing why the author needs it and how it may be used in the future would be helpful. If it’s for notifying the user about new videos (since many sections are still not ready), that could be done using an RSS/Atom feed too (not saying email shouldn’t be an option, just that it could be optional).
A user could sign up using a disposable address or an address used only for random signups. But I personally see this as a barrier.
You get access to the courses for the “price” of your email address; the author sends you updates about the course you signed up for and mentions their paid courses as an aside.
It's a common pattern in the developer education market and has long been used by Wes Bos and others: https://cssgrid.io/
I signed up for Gophercises (same author as Algorithms with Go), which also asks for an email address: https://gophercises.com/
I've received at least one update email about Gophercises with a short note that the author also has paid courses available. I don't mind the upsell attempt at all; it's entirely reasonable given the value I got from the free course.
It was a fantastic way for me to learn as it provides a ton of small real life projects as exercises with videos of how to build them with live coding.
