Cron Emails not being sent

I’m using latest version of WordPress & Email Subscribers. I’ve set up a cron in CPanel to run every hour. It is running successfuly, ie, generating output. Number of emails is set to 90, as the host permits 100 emails per hour. I’m using Mail Bank’s WP email plugin & using the SMTP sending method. If posts are published immediately, it works, but, having > 300 subscribers, this would quickly exceed my mail limits. I’m also receiving emails such as notification that my cron url was triggered successfully, so that is not the problem.

Cron output also suggests it’s going back & picking up posts from a very long time ago, ie, 2/23/2018, which, if true, is obviously highly undesirable behavior. Here is the output from the last cron job.

                        <p>In a recent News Tribune piece, Sam Cook, far and away my favorite Northland writer, declared he was mulling another book. Go for it, Sam! I need another dose of your wit and philosophy as I continue my final portage.</p>
<p>If I talk woodsy, it’s because that’s what I am—from childhood on.  Kind providence set me on a path that included wilderness treks from Maine to Alaska. You can read about some of them at <a href="http://www.lloydsstorytree.com">www.lloydsstorytree.com</a>.</p>
<p>Sam’s article led me back to Quiet Magic, his second book (1998). I read his account of Hawk Ridge and smiled. My first-ever campout was there, 1935. My buddy and I slept on the ground under the stars rolled up in a blanket. We cooked breakfast over an open fire.  There was no road in those days.</p>
<p>A favorite day hike was to follow the ridge of the hill and across Amity Creek, Lester River, and farm fields to Moose Mountain, where we’d cook lunch and hike home, I caught my first trout in the Amity.</p>
<p>A while back I wrote a small leaders’ manual called the Wilderness Way, partly how-to, partly philosophy. My thesis: removing a child form direct involvement with the necessities of life damages his soul.  Trail living finds food, shelter, and clothing your pack. You walk (transportation).</p>
<p>Nature is God’s other book.  We need to quit yacking and get out there, look and listen. And take kids with us.</p>
<p>I’ll be watching for that new book, Sam.</p>

I use a default theme, I’ve deactivated all plugins except yours & Wp Mail Bank, & the problem persists.

I’ve deleted the plugin, including its database tables, then reinstalled, w/no help.
