I wonder if it is possible to split the marketing email list between people who already paid for the product and those who are constantly peppered with FOMO emails to buy.
I really want to keep receiving information about product updates, new features and improvements, especially in the beginning when these things change frequently. At the same time, I couldn't care less about how many copies remain to be sold at what price or whatever.
If it is possible to unsubscribe from the FOMO list but keep receiving product updates emails, it is not an obvious one.
