Can I set a Reply-To Email Address for a campaign?
Yes, in the campaign options you can set a reply-to email address. Each email will be sent from your account but when the recipient clicks reply the email will go to the email address is specific. If you leave the email empty then the replies will simply go to your own account.
You can add multiple reply-to addresses by adding them to the field separated by a comma, but note that not all clients support this feature (e.g. some Android and Mac mail clients have been reported).
