Hey Superp,
Thank you so much for your input here! Followed your steps with the Klaviyo Branded sending domain and copied everything over to the DNS Setting on Shopify. Got all the green arrows and says active. Now just have to test this all out and finger crossed! Thanks again for being one of the few that’s leading this discussion. Was speaking with a few other people in this space that didn’t know these changes were coming! lol
I will check out the MX records you have mentioned shortly!
On your last point! Thanks for pointing me in this direction and validating what I did earlier was correct! When I regenerated the DKIM again today, it got me down below the 255 character limit (which was odd as it wasn’t doing that yesterday) and I also ran the authentication on the DKIM google page along with the EasyDMARC platform and confirm they are all in place!
Thanks again Superp!
