The cc list
Members can notify non-workspace email addresses when there are comments on database records using the cc List. When email addresses are placed in the cc List, iMeet® Central will notify these non-members via email when comments are added to the record (all other information is stripped from the email).
Email addresses can be added to the cc list by selecting Share > cc List.

Any comment made to a database record can be cc'd to the existing list.

Non-workspace member replies
Replies from these email addresses will be logged in the appropriate database record and re-syndicated to only workspace members subscribed to the record.
