Hello sportwelt,

thanks for reaching out to us.

Unfortunately, there is currently no such option with Amelia's built-in features. You can suggest that feature on the following link: https://features.wpamelia.com/ 

We carefully follow suggestions from our customers and the more vote the feature gets, the more priority we put on implementing that feature in one of the future updates.

Currently, booking multiple appointments from the same or different services is possible with the Packages features, Events cannot be used with Packages, only Appointments (Services).

Please, let me know if you have any other questions.

Hello sportwelt,

An issue with email notifications could be caused by several reasons:

1. Your hosting provider is blocking all 3rd party settings and only allowing their SMTP (or other) settings.
2. Your website has a PHP version of less than 7.
3. The credentials are not correct.
4. There's something else blocking the notifications from being sent.
5. If you're using Gmail, please check out this article for detailed setup instructions.

Please, let us know when you check this.
