I can't find any google solution that matches my problem.
- Cron is working.
- Order e-mails are sent with success.
- All other e-mails are working too, excepting newsletter.
My last newsletter was sent using 126.96.36.199. But after updates to 188.8.131.52 my newsletter e-mails are not being sent.
Cron schedule table shows up all queues, including
newsletter_send_all with success message.
Going to backend I can see ZERO
processed from thousands of subscribers.
No newsletter e-mail was sent.
No errors in Magento logs, PHP logs and Apache logs.
What could be happening?
