Reply to Mentions via email
I just noticed that you are now able to Comment on Notes on the contact record, much like the new Comment feature in Conversations.
Very nice QOL update.
What would be even better is when someone @mentions a user on a note or Conversation, you can reply to the email notification in your inbox and it will automatically log your reply in HubSpot as a new comment.
I find that my team often replies to mentions by forwarding the notification email to the sender, but all of that communication lives in our email inbox and not on the contact record.
