Is there a way to limit the number of emails sent per campaign?

[Anonymous]

We had a situation recently where the smart list was inadvertently updated which caused the email to  be sent to a larger audience than intended. While this was not a huge error because the email content was generic, I want to set up a limit to ensure that we don't accidentally send to hundreds of thousands people. I know we can limit the communication per lead but I couldn't find anything that would limit the number of emails delivered per campaign. Is there a way to do this?

You can set Smart Campaign Restrictions as Steven mentioned above. Once you set your limit, if you run a smart campaign that exceeds the limit you configured, it will show an error and will require you to manually override. Giving you that extra security
