MailPoet plugin compatibility

[costasovo]

I am a developer for the MailPoet WordPress plugin, and I wanted to bring an important update regarding the use of our internal code to your attention.

We have noticed that your project is utilizing code within the \MailPoet\Models namespace. This code has been deprecated for some time and has been triggering warnings. It was not intended for external use. We have always provided a public API.

We have prepared a pull request to remove this obsolete code entirely. This change is necessary to maintain MailPoet's integrity and performance. The pull request is ready and will be merged soon.

To avoid disruptions, please update your project to stop using the \MailPoet\Models namespace code instead of relying on our provided public API. If this update is not made, your code will fail once the pull request is merged and the new version is released. We aim to release it within the next couple of weeks.

Thank you for your understanding and cooperation.
