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.

DNS lookups needed to validate the record
This SPF record exceeds the maximum of 10 DNS lookups. Often, unnecessary entries can be safely removed after evaluating DMARC data. To learn how to address the "Too many lookups" issue, read our guide here:
This record has a high lookup count. Review and adjust as needed based on this domain's DMARC data
This record has a low lookup count. Review and adjust as needed based on this domain's DMARC data.
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.
