Subscribers not receiving new posts via publicize

I checked your Jetpack settings, and it seems that you don’t have any Jetpack Subscribers yet. You’re the only subscriber at the moment.

You can follow the instructions here to access your list of Jetpack Subscribers:

The Subscription form you’ve added to your sidebar comes from another plugin, Subscribe2. You’ll consequently want to contact that plugin author if you experience issues with their plugin.

If you’d like to use the Jetpack Subscription form instead, you can do so by activating Jetpack’s Blog Subscription widget under Appearance > Widgets in your dashboard.

I really would love to know though, how I got my 10 subscribers (notified to me via wordpress each time), if they didn’t come through Jetpack?

Jetpack Followers and your site’s subscribers are indeed different. You can read more about the differences between the 2 here:

Jetpack doesn’t have any control over your site’s subscribers and won’t send them subscription emails since they didn’t subscribe through Jetpack.

If you want to disable user registrations on your site, you can do so by going to Settings > General in your dashboard.

I did like the idea of using Jetpack for everything, but unless I can find a way of getting it all working correctly, I guess I’ll have to stay with subscribe2.

If you add the Blog Subscription widget to your sidebar I’ll be happy to subscribe to your site and see if things work properly. Right now, I don’t see anything that would stop Jetpack Subscriptions from working properly.
