SPF Record

An SPF record is a DNS TXT record used by receiving mail systems to check whether a sending server is authorized to send email for a domain. A home repair business using both a mailbox provider and a marketing platform needs to understand which services legitimately send its messages. SPF is one part of email authentication, not a complete solution to spoofing or spam filtering. DKIM and DMARC address other important aspects, including message signatures and alignment. A malformed or outdated SPF setup can cause valid mail to fail checks. Follow each provider's documented configuration and test results instead of assuming an SPF record guarantees inbox placement.
