Thank you for reaching out to the Community with your inquiry. I understand how having this functionality would be helpful in situations where an e-mail goes out with a misspelling or mistake. At this time we do not have the ability to recall a campaign that is sent. This is due to current technological limitations. There are many different e-mail clients on various servers and the way the system is set up is that once the e-mail is released from our system, we have no tether to it.
This prevents us from being able to recall the e-mail and make corrections. Of course, technology is ever changing and improving so we are always collecting feedback from our customers regarding this feature. I would be happy to pass this along to our product teams for you. I am sorry for any inconvenience this causes. I recommend scheduling the e-mail for at least 10 minutes out from the time you want it to send so if you're doing any last minute reviews you have a chance to catch them and unschedule it.
