Setup is running Magento 2.2.5 on Linux, PHP 7.2, hosted instance.
What I’m trying to do
I have schedule Cron jobs to run once a week. I scheduled a newsletter to be sent to my 100+ customers. The cron job sent the newsletter to only 20 customers. I then had to schedule the cron job to run every 5 minutes to send newsletter to next 20 customers. The job ran several times at 5 minutes interval until my newsletter subscribers list was exhausted. Then I rescheduled the cron job to run once a week.
Isn’t a single cron job supposed to send the newsletter to all subscribers? Why did I have to play with Cron job frequency? There seems to a be flag/setting somewhere that defaults to sends newsletter to only 20 customers at a time.
Has anyone else run into this issue? Would love to hear from this forum.
