I hope you don't mind me hopping onto this thread, I'm also having issues verifying my domain in order to send marketing emails.
My website URL is hosted by Godaddy and I have a custom email address that I use within gmail (Google Workspace) (something along the lines of: info@example.com).
I've added all the requested DNS settings in my Godaddy account (listed below:)
CNAME squarespace._domainkey squarespace-domainkey.squarespace-mail.com
TXT @ v=spf1 include:squarespace-mail.com ~all
TXT _dmarc _dmarc
But in Squarespace, it still indicates that the second one isn't added. I even spoke with a Godaddy specialist to verify that it was done correctly, and he confirmed that it was.
I've been waiting 5 days for Squarespace to reply to my email and their live chat is unavailable.
Would really appreciate some help....
