Currently, when you send a message via the portal, the client receives an email, as they should. However, if the "channel" goes unread, and any subsequent emails are sent, they will not get a second email notification to avoid "spamming" the client. While this understandably makes sense, the issue lies in when there are 2 different messages, sent on 2 different days and the client does not login to view them, a 2nd email is not sent.
There is also the issue that when completed forms/notes are shared via the client portal via the "share" button on the note, it does not send an email to the client letting them know there is a new shared document with them. This also needs to be fixed/addressed.
