Email Subscribers Not Showing In Follower List

Hi, all. New to WP, so bear with me. Using the Cubic theme with the free web-based version of WP, so I assume it’s the most up to date version (couldn’t find that information in my account.)

I’ve been told by a couple of folks that they’ve subscribed (one said they confirmed their subscription) and they’re not showing up in my email follower list. I do have around 50 subscribers already. I have two places to do it- the WP follow button on the homepage and in Contact in the main menu using the Cubic widget available. globaldebauchery.wordpress.com. It’s possible folks are saying they’re subscribing and aren’t, of course, but wanted to check it out because I’m worried I might be losing subscriptions.

Any help would be greatly appreciated. Thanks!
