To check if zufrans.com 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 zufrans.com.

With a recent registration date of January 24, 2021, and a risk score of 27, zufrans.com has a poor email sender reputation. The absence of DMARC enforcement and a strict SPF policy (-all) further complicate deliverability. Classified as a disposable email domain, and with invalid SMTP, emails from zufrans.com are undeliverable, often flagged as suspicious by providers.

To improve domain reputation, zufrans.com 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.
