Hi Lerou 🙂
Welcome to the Pre-Sales Questions Channel and thank you for considering our plugins for your project! There is currently no feature which allows for users to subscribe to get notified when events are published, but I’m sure there is something available in the WordPress plugin repository that can accomplish what you need.
I know of the Event Calendar Newsletter, though I’ve never personally used it so I’m not 100% certain on it’s features and limitations. After a quick Google search, I came up with the following plugins, but again I’m unfamiliar with both of them so you’ll need to do some reading and testing to see if they’ll work for you:
• Better Notifications for WordPress
• Post Notification by Email (Old Notify Users Email)
If you’d like to see this feature included in an upcoming release, we welcome user suggestions with open arms at our UserVoice Feature Ideas page. I hope this helps get you started in the right direction and please let me know if you have any additional questions. Have a great week ahead!
Cheers 🙂
