Share files with non user

We’d like to be able to share files with clients without having to register them as a nextcloud user. We have the email setup working, but it looks like we can only email to registered users. Is there a setting we are missing somewhere that allows emailing and sharing files to users that are not registered in the system?

We may have figured this out, but it appears to send email out as the user that shares it. We’d like it always to come from a specific user that is registered as an AWS ses sender.

I too want to share folders with people I don’t want to register as users. Currently I need to share with 100+ people.
My current workaround is the using “box”.
However I prefer to use our own NextCloud.
