Hi there, amazing Shopify community. A quick question for you guys. How long do I need to send out emails, to have enough data to now finally come to a conclusion on how to go about cleaning up my email list of subscribers for those who are not engaging in my emails? I have been sending emails since I started my online store with shopify to my subscribers, and I think it's been over 6 months now. I feel the data I have from these emails isn't enough as I should probably give it a year to have a more concrete data to determine subscribers that fully engage in my emails and take out the ones that don't. So how long is enough for concrete and a more substantial data?
