Nice to get my newsletter for people learning to code without a CS degree over the 2k hump.
I've been able to monetize it from day 1 so I'm fine with steady growth. Some people might grow faster but they aren't making any money from their list.
My job board newsletter is growing a lot faster but that's understandable - people need jobs more than they need content.
I've recently switched to delivering all the content within the newsletter just like indiehackers does. I do provide a link to the website if people want that option but I've seen some really high open rates with this approach. Some times in excess of 50% which is pretty good for a newsletter of 2,000 people.
