SPF Surveyor
Our SPF Surveyor provides a graphical view of DNS records that allows you to more easily identify which third-party email sources and IPs are authorized to send on behalf of a domain. The tool will also verify that the SPF record has correct syntax and is free of errors that could lead to diminished email deliverability and failed email authentication.

This record utilizes a considerable number of DNS-querying mechanisms / modifiers. Attention should be paid to determine if that number should be reduced.
This record utilizes a small number of DNS-querying mechanisms / modifiers. No fixing is required. If this record is meant to be included by other records, consider reducing the number of DNS-querying mechanisms / modifiers (if possible) to keep total resource consumption low.
This record utilizes no DNS-querying mechanisms / modifiers. There are no efficiency gains to be made in terms of reducing the number of DNS queries.
