So sorry to hear the wrong flyer was sent out! Did you originally select a different flyer than the one that was sent? Is this email a copy from a previously sent campaign? At this time there is no way to recall an email once it has been sent. Though this may be true, we want to make sure you're assisted. In these cases you can make a copy of the email, update you subject line, replace the incorrect image with the correct flyer, and resend it to your contacts. I apologize for any inconvenience this may cause!
