DKIM/SPF and DMARC

[CColotti]

I am moving forward with the same Square for Restaurants and Email marketing from Square and I run very strict DMARC on my domains.    I've been concerned this is going to be an issue for the order emails as well as the marketing ones.  There is conflicting information how to set this up for the weebly site to send emails as well as the EMail marketing side of Square.

My understanding in reading other posts is this is not very clear how to configure for DMARC compliance on either Square online OR marketing, can someone please clarify this?  Disabling DMARC really is not a good option and ensures better email delivery.
