Messaging tied to email relay, plus unread alerts

I have in app messaging set up in my marketplace app, using this feature…

  1. I’d like to set up an email relay, likely using sendgrid, tied to the in app messaging - any documentation available to tie that into the Canvas messaging module?

  2. I’d like to display an unread messages icon in the header- any documentation available to help me implement this?

Thanks in advance folks :slight_smile:
