The majority of legacy email infrastructures do not support SPF macros, causing catastrophic deliverability issues. So, Dynamic SPF was developed as a future-proof solution.
Robust and failsafe
Does not rely on a macro-based approach that many other vendors use, meaning that all legacy email structures, gateways, and receivers support it. Where others claim reliability, we guarantee it.
No need for human intervention
A dynamic include statement monitors and updates IPs continuously. We dynamically flatten and compact SPF because it is simpler, virtually unlimited, and works with all devices.
Ensure 100% email deliverability
Monitors and heals syntax errors using ‘last known good’ values. If errors are encountered, they are skipped and emails continue to flow. When errors are fixed, Dynamic SPF automatically incorporates the updated values.
