Joachim Haerting While we already support sending emails to individuals, we are also working on sending emails when you share to a user group. Group share emails will most likely land in 6.0 release.
To ensure that share emails don't land in spam, you can change the 'from' email address to use your company's domain. Like: firstname.lastname@example.org.
