To check if sauto.me has been flagged by spam filters, we need to see if the domain or its IP address is listed on common DNS-based blacklists, run diagnostics on SPF, DKIM, and DMARC, and review sender reputation metrics. Use Abstract API's IP Abuse Check tool to get a complete report on abuse, blacklists, and suspicious activity for sauto.me.

As a recently registered domain with a low risk score and no DMARC enforcement, sauto.me's email sender reputation is mixed. The strict SPF policy helps, but the lack of DMARC enforcement and disposable email classification can raise concerns. Despite these factors, the domain is still deliverable, but recipient mail systems may scrutinize messages more closely.

To improve domain reputation, sauto.me should promptly implement DMARC with enforcement, verifying messages originate from authorized servers. Next, maintain a consistent sending volume, avoiding sudden spikes or suspicious patterns. Third, remove the disposable email configuration, ensuring legitimate user accounts. Finally, authenticate email traffic using DKIM, proving authenticity and deterring spoofing attempts. These measures will significantly improve trust and reduce spam filtering overall.
