Hey Brigi, thanks for posting! There's no tool to do this automatically, but I can think of a way to do this with the existing tools in your account. You could segment out email addresses that belong to your company, perhaps by using the domain name of the email address. Then send out two versions of the mailing: one to your company, and another to the rest of your audience. This will result in two sets of response data, one of which excludes your company.
I hope this helps! Please let me know if you have any more questions!
