Why it matters
Domain email-health audit
Deliverability records don't fail with an error message — they fail by having mail quietly land in spam, or bounce on an alignment mismatch nobody thought to check. Finding that out from a sinking open-rate dashboard three weeks into a campaign is the slow, expensive way. A one-click audit before you send is the fast one. The records involved — SPF, DKIM, DMARC — interact with each other in ways that are easy to get subtly wrong even when each one looks fine in isolation: an SPF record with too many lookups, a DKIM selector that doesn't match what's actually being signed, a DMARC policy set to none that provides no real protection at all. None of that throws an error anywhere in your sending pipeline; it just quietly determines whether mailbox providers decide to trust your domain. A domain that's about to run its first serious cold-email or marketing campaign is exactly the moment this is worth checking, because fixing a DMARC misconfiguration after a campaign's already tanked your open rates is a much slower recovery than catching it beforehand. It's a rare case where the fix is often just a single corrected DNS record, if only someone had looked before the campaign went out. A domain's reputation is slow to build and fast to damage, which is exactly why it's worth checking before, not after, a big send.
