Mailgun send a warning mail about increased bounces from our account. Sure, they know what's going on... but we send 4-5 digit mails per hour - it's a lot of bounces

That means I can't just resend the the emails blindly, because I'm too scared to trigger some sort of automatic suspension...

(I don't do this regularly, so I'm not familiar with all features... additional mail verification could help probably ....)
