Hello! Since SPF, DKIM, and DMARC records are a different request than adding a domain, next time could you please create a new thread for the new request? This will help us keep requests clear, help make sure they're not accidentally missed (since this one was already marked as [Solved]), and help us escalate them to the right level of admins. 🙂
A root admin can set up the email DNS for you, I've escalated it for their attention and removed the [Solved] this time.
