A person reads every report sent to abuse@mailmundo.com and answers it.

Sending policies

• A domain can't send until its DKIM and DMARC records check out.
• Hard bounces and spam complaints suppress the address right away, for good.
• Transactional and marketing mail travel on separate SES configuration sets.
• An account that goes over 5% bounces or 0.1% complaints in 24 hours is paused automatically.

Reporting

DMARC aggregate reports go to dmarc@mailmundo.com.

Block-list inquiries

If our sending IP appears on your block-list, please email abuse@mailmundo.com with: the IP, the listing reason, the time window, and a sample message-id if available.

Customer enforcement

We act on legitimate abuse reports against customer accounts. Repeat violators are suspended or terminated. We log enforcement actions in an immutable audit trail.

Data we provide on request

For valid law-enforcement requests with proper legal process, we provide data we are legally obligated to share. We do not pre-comply and we challenge overbroad requests.
