Check if your DNS changes have propagated globally
About DNS Propagation
When you update DNS records, the changes need to propagate across DNS servers worldwide. Each server caches records based on TTL settings.
Common record types:
- TXT - SPF, DKIM, DMARC verification
- MX - Mail server configuration
- A - IPv4 address mapping
- CNAME - Domain aliases
- NS - Nameserver records
About this tool
After making DNS changes, you need to verify they've spread globally before your emails will authenticate properly. This checker confirms your records are visible worldwide. After changes propagate, verify them with our SPF checker, DKIM checker, and DMARC checker. If emails still fail authentication, use our email header analyzer to debug the problem and see exactly which authentication method is failing.
