Real DNS lookups for SPF, DKIM, and DMARC, the three records that determine whether your cold emails land in the inbox or the spam folder.
Lists which mail servers are allowed to send email on behalf of your domain. Without it, receiving servers can't verify your email is legitimate, and may flag it as spam.
Adds a cryptographic signature to outgoing email, proving it wasn't altered in transit and genuinely came from your domain.
Tells receiving servers what to do when an email fails SPF or DKIM, reject it, quarantine it, or let it through, and where to send reports about failures.
