Hi @joop1,
If you are running one of our Free or Starter plans, and do not have a Premium key or the Premium plugin installed, then you will see this error in the MailPoet log files. It only indicates that no premium key has been found, however, you should still be able to use the base plugin and send outgoing email.
Some things to check:
- a free plan has a subscriber limit, this might be 500 for a Free plan, or 1000 for a legacy Starter plan. If you are over the subscriber limit, sending will be halted.
- Unlike other sending services, MailPoet monitors your sending for spam reports (which come directly from your subscribers) and bounces. If these numbers are too high, we temporarily pause sending so we can help you sort out the issues with your list. This ensures maximum deliverability as your list is clean and in good shape, and protects your reputation online from being blacklisted. If your sending service has been temporarily paused like this, you should see a warning/error message at the top of your Send With page, and you should have received an email notifying you of the suspension. You can raise a ticket with us (use the presales form if necessary) to have service restored.
- ?if you are not actually using the MailPoet sending service (i.e. you have indicated “other” on your MailPoet > settings > send with tab), then there is most likely an issue with that third party sending service. Please reach out to that sender to make sure you are using the correct settings to use their service, and your account with them is functional and set up correctly.
- you might also have other configuration issues such as a domain that is not yet validated, or cron issues. More on those here: https://kb.mailpoet.com/article/231-sending-does-not-work
Please work through this list and see if that resolves your sending issues.
