I have 2 'old' email lists from a site I bought. I did a bounce check for the first part of the list before sending to them but still a lot of emails bounced (13%) and now my amazon SES is under review... is there a more reliable bouncechecker or a service where it's save to send emails with a higher bounce rate? Please NOTE, I am NOT sending spam and the unsubscribe/spam rate was very low (1-2%)! This is an opt-in list with only subscribed users. Any help is much appreciated!
