Understanding the report
You need to scrolll down, you can find a detailed report there.
Globally, the average inbox placement rate stood at 79 percent in 2016. Did you know that an average of 21 percent of all your delivered email is being filtered as spam? The inbox placement rate measures how many messages arrive in your subscribers’ inboxes — and not in spam folders or otherwise undelivered by the mailbox provider. How about deliverability: deliverability only tells which percentage of your sent out email did not bounce and was accepted by a mailbox provider (not necessarily delivered into an inbox).
