SPF/DKIM/DMARC deployment tools fall into 2 categories: generators (creators/builders) to generate records and checkers (validators/testers) to look up the DNS.
SPF Tools
To create/generate an SPF record, there is the SPF record generator, or SPF record creator/builder, which takes these mechanisms and qualifiers: mx, a, ip4, ip6, include, and all, and returns an SPF record.
To check an SPF record, there is the SPF record checker, or SPF record validator/tester, which checks if an SPF record is published on your domain, and if its syntax is correct.
DKIM Tools
To create/generate a DKIM record, there is the DKIM record generator, or DKIM record creator/builder, which takes a domain and a selector, and returns a DKIM record.
To check a DKIM record, there is the DKIM record checker, or DKIM record validator/tester, which checks if a DKIM record is published on your domain, and if its syntax is correct.
DMARC Tools
To create/generate a DMARC record, there is the DMARC record generator, or DMARC record creator/builder, which takes these tags: p, rua, ruf, sp, adkim, and aspf, and returns a DMARC record.
To check a DMARC record, there is the DMARC record checker, or DMARC record validator/tester, which checks if a DMARC record is published on your domain, and if its syntax is correct.
