Are there risks associated with SPF flattening?

SPF flattening risks:

Stale data: Provider IPs change without notice. Flattened record becomes incorrect. Mail fails SPF.

Maintenance burden: Must monitor source records and update flattened version. Manual process is unsustainable.

Record length: Flattened records with many IPs may hit TXT length limits.

Reduced flexibility: Cannot benefit from provider's dynamic IP management.

Audit complexity: Harder to understand what services are authorized from a list of IPs.

Mitigation: Use automated flattening services that monitor changes and update automatically. Never manually flatten and forget.

Copied documents become outdated if the source changes. Automated copying systems reduce this risk.
