Blog Subscriptions not working.

Hello! I hope I’ve found you well.

While I don’t have a whole lot of subscribers right now, the ones I do have are in my close circle of friends. they told me that they subscribed, they received the confirmation of the subscription, but do not receive e-mail updates when I upload a new blog post. I myself subscribed for troubleshooting purposes but it doesn’t seem to e-mail me either. Any fixes or ideas for how to get this running?
