Case studiesEmail deliverability: authentication alignment and sending-path coherence
Aligned with the deliverability sequence in approved copy: find the cause, clean up the setup, validate the result. This draft centers SPF, DKIM, DMARC, and alignment with the actual sending stack—without claiming a measured inbox rate.
Outbound mail showed spam-folder and inconsistency symptoms tied to authentication gaps and DNS drift relative to the sending tools in use. The team needed a precise picture of what was broken and a safe order of fixes—not another generic “warm up the domain” checklist.
Review DNS and the full sending path: SPF, DKIM, DMARC, and alignment with real from/subdomain behavior. Reconcile records with the actual sending configuration, then validate after changes using the same signals mailbox providers evaluate.
Technical mechanism described; no promise of a specific spam-folder outcome.
