I received 290 email responses to a single email broadcast from MAILER-DAEMON@yahoo.com. Many of the email addresses generating this bounced message have opened and clicked other emails within the past 3-4 weeks. Is this really a widescale full mailbox capacity issue or is ConvertKit sending emails that are getting bounced for some other reason. That's a ton of bounces for a single broadcast. The average number of bounces per broadcast are 5-10.
