What is SPF Flattening?

SPF flattening is the process of replacing complex SPF records (with ‘include’ statements) with direct IP addresses. This reduces DNS lookups, ensuring your emails pass authentication without hitting the 10-lookup limit.

Without SPF flattening, your email may fail SPF checks, harming deliverability and exposing your domain to spoofing.

“PowerDMARC eliminates the SPF lookup limit on our domains with the hosted SPF; we only need to publish 1 SPF record to our DNS.”

Jennifer Heisel
Systems Administrator

“PowerDMARC helps a lot with SPF errors, in particular, by making it easy to do “SPF Folding,” which is often needed for customers who need more SPF includes than are otherwise technically allowed.”

David Spigelman
President

“With SPF flattening, we were able to easily expand the SPF includes to inspect the specifics of the record.”
