I see Buttondown a lot, and it says it's free for the first 100 subscribers.
I don't know how many subscribers I might reasonably get, I would be very surprised if I hit 100, but if you do get more than that, do they ask you to start paying up or do they cut off new subscribers?
I'm not in a financial position right now where I want to put money into a service month over month, but I also think getting a newsletter started could be useful for the occasional update. Trying to look into all my options.
