Welcome back! I looked at my subscribers for the first time ever, today. I have 60-something. I don't recognise most of them. Some of them I recognise, but know they never engage with my stories. I'm pretty sure they never read them. It's a bit odd that they continue to have my stories delivered to their mailbox, to be honest. Saying that, I wouldn't even know how to access open rates. I'll let them decide if they want to unsubscribe. It doesn't matter to me. But it does go to show that subscribers are no better than followers, unless they're reading.
BTW, I tried to get a US phone number through openphone today. It appears I need a US phone number to verify my account before I can get a US phone number. ๐ I'm not beaten yet though.
