Hi,
Michal here!
I have a Freemium Newsletter http://kickstartsidehustle.com/ providing viral marketing case studies.
I was stuck taking care of my grandparents. My whole family was on quarantine (strange times!), I figured I wanted to test something.
I've checked my email list of 1200~people, looking for the highly engaged users, that were receiving my emails for at least 1,5 months.
I came upon 400 emails of people that have opened my every email, at least a few times.
I emailed them with the offer:
I let them choose the price (I use gumroad for subscription) starting at $5/Year. They could stick with $5 or could pay more.
My usual subscription costs $50/year, but I knew that for some people even that price could be high, especially outside the US.
The results of 2,5 days of promo:
It's not much, but at least I know I've helped a few people - received a few "Thank You" emails ;)
