Conclusions and opinions about the plugin

I scanned your plugin, after a thorough examination I am convinced that there is good potential in this plugin, since it supports Elementor and also supports adding CSS.

However, I think there are a few things missing from it:

1. It is possible to send only to predefined lists, and not to individual users or email addresses. Which means that every time you want to send a formatted email to a user, you have to create a user, create a list and only then send.
2. There is no tracking of links in emails that are sent to see which links were clicked.
3. It is not possible to add attachments to emails.
4. It is not possible to create recent posts dynamically (as in competing plugins) every period, this means that every time you send recent emails you have to manually select the posts that were not sent in the previous email. This means that in the leading plugins you can prepare an email at the beginning of building the website and go to sleep for a year. This is something that this plugin does not have.
5. No developer documentation. For example, I tried to develop the possibility of adding attachments, and I could not find any documentation on the subject.
