Are you aware that the Newsletter tool in Cs-Cart is totally bugged, right?

As per title, are you aware?
Unsubscribe not working, trying to send a newsletter and an old one in some kind of old cache is sent?
How know what else…

No. To be honest, we are not aware of any, nor have we received any reports from our customers recently. If you would like to report a bug, please follow the guidelines:

And follow this reporting format:
Where the problem occurred: Write here the product (Store Builder or Multi-Vendor) and its version. The version can be found in the admin panel by adding the ?version parameter to the end of the address (for example, https://example.com/admin.php?version). If the problem is on our online demos, then a link is enough for us.

Details of the problem: Write what the problem is. A screenshot will help a lot (if you can see the problem). It is desirable that the entire browser window be in the picture, and not just a specific part of the page.

How to reproduce the problem: Describe the sequence of actions and circumstances that lead to the problem. Any additional information can help: your browser, operating system (important for Android and iOS mobile devices), PHP version on your server, etc.

In order to confirm and fix the issue, we first need to replicate it on our store or demo (without any 3rd party add-ons and themes). If this fails, we will ask you to contact us via Help Desk for further investigation.
