DNS Housing Issue

A WHOIS lookup is showing the domain registrar is Domain People.inc. It is likely Domain People, Inc who manages your DNS using AWS to host the name servers since you have mentioned you don't have an AWS account. If you haven't done so, I would suggest you to contact Domain People, Inc first.

Your domain, famlawaz.com, is using Route 53 and Google for DNS and email hosting respectively.

From what I can tell, the domain do not have DMARC and DKIM DNS records. Yahoo and Google announced last year that email senders must have DMARC, DKIM email authentication measures in place beginning 2024.

You can refer to their websites for exact requirements and implement them

• Yahoo: More Secure, Less Spam: Enforcing Email Standards for a Better Experience
• Gmail: Email sender guidelines

Here is Google's guidelines on implementing DMARC Help prevent spoofing and spam with DMARC

As AWS-User-alantam@ mentioned, perhaps your domain registrar is managing your Route 53 DNS access, or someone in your company configured DNS hosting to R53 previously. Suggest you check with your domain registrar AM.
