We've added Email Deliverability feedback to your D4H account. Once you send an email to other members of your team, you'll start to see realtime deliverability reports as they arrive at the other end. If the user has an invalid email address, or the message bounces, we'll let you know on your dashboard.

If you go to Logistics->Email->Email Status you can see a real-time view of the current status of each members email. If if's delivering, bouncing, invalid, or messages are going to spam.

We want to make email more reliable for you when in emergency response situations and deliverability reports are our start on that.
