Hi Linas,
Thanks for using our plugins!
Since you seem to be a current user of our premium plugins, I recommend reaching out to our support on the premium forum. Over there, we have the capacity to provide more technical and rapid support. This Pre-Sales forum is reserved specifically for questions about the features of our plugins for users who are making decisions about which, if any, to purchase.
However, while I have you here, I will point out that, unless I misunderstood, emailing your users seems to be more of a WordPress question, and less of a question about our plugin. There are several good plugins in the repository that would allow you to email your users links to your new events. 🙂
Let me know if I can clarify any of this & best of luck!
Best,
Shelby 🙂
