How can I successfully authenticate my email domain?

Hi,

I am having issues authenticating my email domain , currently have my domain registered with gandi.net however i transferred my email over to obambu last year, When i transferred my email to obambu, i created an spf record and a dkim record in gandi provided by obambu. problem is i have been trying to authenticate my domain adding dmarc record in gandi-

v=DMARC1; p=none; rua=mailto:mystore@email.com

added the 4 cname shopify record in gandi

Still its saying domain has not been authenticated

Because your email domain hasn’t been authenticated, recipients will see your email as store+65640923386@shopifyemail.com. For better brand recognition, authenticate your domainand ensure your domain has a DMARC record.

any help greatly appreciated

@sam163 Have you checked your DMARC record entries ? what it is showing? you can check the DMARC records here - DMARC Inspector - dmarcian
