Dynamic SPF management for enterprise email authentication
Automated SPF flattening breaks through the 10-lookup limit and keeps email flowing without manual SPF record updates or compatibility risks.
SPF (Sender Policy Framework) records control which systems are allowed to send email for your domain. But as email ecosystems grow more complex, SPF becomes increasingly fragile, turning routine changes into delivery risks.
Each email service you add increases DNS lookups in your SPF record. Once the 10-lookup limit is exceeded, authentication can fail, causing legitimate mail to be rejected or sent to spam.
Static SPF records become outdated as vendors change infrastructure. A single stale entry can invalidate SPF checks and disrupt email delivery.
Some solutions use "macros" to get around the limit, but most older email systems don't support them. This creates compatibility issues with email gateways and can cause failures.
Automatically stays current and keeps email flowing
Updates happen at the moment of authentication, so your records are always accurate. If a temporary error occurs, Dynamic SPF uses the last working configuration to keep email moving until it resolves.
Works with all email systems
Designed to work across modern and legacy email infrastructure worldwide, without issues in older systems or email gateways.
Manage everything in one place
Dynamic SPF lets you manage and update your SPF record directly in OnDMARC. With a single DNS change, all future SPF updates are handled centrally, without ongoing DNS access, third-party permissions, or fragile workarounds.
Built for reliability
Runs on enterprise-grade Google infrastructure with automatic failover. Even if OnDMARC experiences downtime, Dynamic SPF continues authenticating your email.
Built for organizations that depend on email
If your business relies on email across many tools and services, you need authentication that keeps up without constant intervention.
