Ok, so if I have 3,000 plus users and I can only send 200 emails per hour on my web host account, then I can leave the browser window open while that is going out for 15 hours and the newsletter will go out, even if my computer goes to sleep but still has that browser window open?
I realize this is a bit of a hack but I’ve been trying to fix this wp-cron thing for two weeks and there is very little written about it and no response from WordPress.
I went on a plug-in and resource reduction diet (Jet-pack’s social plug-in makes touches the server 10 PER PAGE that is loaded). I also had to remove Meteor Slides as it loaded all the slides on every page call even though I only used it on the front page. I signed-up with Content Caching Network (Cloudflare), and installed a database caching plug-in to reduce strain on my shared host.
All of those steps that seemed to get my cron working again.
The reality is I don’t really know what caused my cron NOT to work so I don’t really know how I fixed it.
Cron Is definitely required even in the pro version in order to have your messages continue to send even if you are not actively sending them in the browser. In most cases when the cron does not work, it is due to an issue with the hosting provider or with a Plug in conflict.
