Works like a charm

When I first installed it I had to really find out how the plugin works, so I clicked open all pages and settings.

I did not work for me at first, but then I found out that I needed to toggle the campaign on (Email subscribers > Campaigns). Futhermore, I had to configure a cronjob, as described in Email subscribers > Settings > Email sending, because WP cron was not working for me with the few visitors I get (private family blog).

Then it worked like a charm! It is really a complete plugin, even without the pro version, and it does exactly what I needed it to do.
