Hi @Shekhar
thanks for your solution, but the email should not always be sent.
In a nutshell: we have built a kind of “news portal” for many business customers. When a customer decides to book the service, first the users are created (without sending an email), the account is set up and tested. When the service is activated some time later, all credentials are sent at once. We need this functionality only for individual stragglers (hence the checkbox).
