Thank you for your reply.
My DNS records seem to be working correctly, except for SPF which reports 'SPF Permerr' error: "Too many included lookups (12)." I suspect this 'SPF Permerr' is what is causing my domain emails non-delivery.
I wanted to try modifying my SPF values to: v=spf1 include:websitewelcome.com all , or maybe Ezoic's suggested default: v=spf1 include:mail.emailyak.com all to see if that can fix the "SPF Permerr".
However, I am not sure if any of those two SPF values would be correct.
Could you please let me know if using either of the two SPF values would be correct before we make the change? I'd hate for my site to go down when making the change.
I'm not well-versed on this "SPF Permerr". I'm looking for help to fix the issue and ensure domain email delivery.
