The SPF Surveyor is an SPF diagnostic tool that presents a graphical view of SPF records. The graphical view allows people to quickly identify which servers are authorized to send on behalf of a domain. (Note that this diagnostic tool focuses on domain-level authentication and largely ignores the portions of SPF that deal with the local parts of email addresses.)
Why perform an SPF check / SPF Lookup?
- Find out if your SPF Record has been published correctly
- Prevent mistakes in the formatting of your record, which can cause email deliverability issues
- Discover any discrepancies regarding your SPF record

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.
