Check if your DNS changes have propagated worldwide. Query SPF, DKIM, DMARC, MTA-STS, and TLS-RPT records from 12 global nameservers simultaneously.
After adding or changing DNS records, changes don't take effect everywhere immediately. Different DNS servers cache records for different durations (TTL). This tool shows which servers have your latest records and which still serve the old ones.
Most DNS changes propagate within 1-4 hours. Some can take up to 48 hours depending on the TTL of the old record. If you lowered the TTL before making changes, propagation is faster.
Scan your domain after propagation completes to verify your records.
