Jenny, your domain doesn't cost anything because it's a substack domain. Jen is using her own domains (they don't have .substack in them), which you have to purchase the rights to use. So it's free to have two substacks, but not to use your own domains.
I just want to say how much I'm enjoying my time on Substack.
I have two newsletters:
www.youareodd.com
www.thefirstyearsofmarriage.com/welcome
I'm considering starting a podcast too and want to know if you get good analytics through substack platform.
Do you link your two newsletters together (do they have the same subscriber base) or are they completely separate?
Totally separate!
Thats great
How much does it cost to own and operate two domains?
A one time fee of $50 each to set it up for Substack and then $12/year per domain on Google domain
