To email a record, select the records you want to send, right-click to bring up a dropdown menu, and select the "Send record" option.
You can also send multiple records at once by selecting multiple records, right-clicking, and selecting the "Send all selected records" option.
This will bring up a dialog box in which you can type the email addresses of the people to whom you would like to send the records.
Emails sent this way will come from the email address email@example.com to ensure those emails aren't flagged as spam. At this time, there isn't a way to change the sending email address.
