Why fix this today

Your SPF record uses 1 of 10 DNS lookups — complexity adds maintenance risk.
Provider SPF records change without notice — your DNS may fall behind.
Manual updates become risky when several providers depend on the same record.
exists is not flattenable.

Simulate next provider change

SPF risk is not static. The next provider update can push you over the limit — unless changes are synchronized automatically.

Current chain

Microsoft 365 adds another nested include

After simulated change

One step closer to the lookup limit.

With SPF Manager

Automatically synchronized

Provider changes are detected, validated, and folded into your managed include — your public DNS stays one record.
