Tagging Contacts via Replied Email?

I am looking to set up an automatic tag to a contact who reply to an email sent via broadcast / campaign.

Is there anyway to automate this via infusiosoft or API ?

There isn’t an automatic way natively inside Keap, but if you are using a 3rd party (like Integromat - now “Make” or Zapier or Parsey that is tied to your reply-to address, you could set something up to parse the email that comes back and tag someone.
