Short answer
Marketing Email, Health tab, gives a score from one to ten from the last 30 days of opens, click-throughs, hard bounces, unsubscribes and spam reports, compared to a HubSpot or industry benchmark. HubSpot's KB lists the monthly limits that can suspend marketing email: a 5% hard bounce rate, a 0.1% spam report rate (one in 1,000), and a 3% unsubscribe rate. While suspended, workflow emails do not send either.
