> One issue may be high hard bounce rates on our very first email sent, but we don't send emails to bounces at all afterwards.
This is a big red flag, though. Are you saying it just happened one single time? In that case, change your IP and start over.
Or are you saying that you regularly trigger a lot of hard bounces? Because if that is the case, that might explain it all right there. High rates of hard bounces are taken as evidence of spam or other nefarious activities, since the typical reasons for high hard bounces are a) a really old list (implies it has been transacted somehow, therefore not opt-in), or b) enumeration attempts.
