Setting up DMARC question


In setting up DMARC, what’s the optimum policy to set? Quarantine or Reject?

I’m always worried about the deliverability of our email from Infusionsoft as well as our business emails sent through Google Business Apps (or whatever they are calling it now). A colleague mentioned that our DMARC policy is set to “quarantine” and this could be impacting deliverability.

Any thoughts?
