Deliverability Audits: what it does
Deliverability problems announce themselves as “my contact form stopped working” — weeks after DNS broke. NimblyMail’s six-pillar audit checks SPF, DKIM, DMARC, PTR records, outbound connectivity, and queue health on a weekly Action Scheduler schedule, caches snapshots for 7 days, and gives you one-click DNS fixes for every failure it finds.
What you get with Deliverability Audits
Six pillars, one audit
SPF, DKIM, DMARC, PTR, outbound connectivity, and queue health — the complete deliverability surface.
Weekly automation
Audits run on schedule via Action Scheduler. Snapshots are cached 7 days so you can diff changes.
One-click DNS fixes
Every failure comes with the exact record to add — copy-paste fixes, not guesswork.
Mailer-aware
Switch from SES to Gmail and the audit reconfigures itself to that provider's SPF includes and DKIM selectors.
Three steps, zero babysitting
Audit runs weekly
Six pillars checked automatically: authentication records, reverse DNS, port connectivity, queue health.
Failures get fixes
Each problem ships with the exact DNS record or setting that resolves it — no deliverability PhD required.
Snapshots prove progress
7-day cached snapshots show what changed, so you can confirm fixes and catch regressions.
Deliverability Audits questions, answered
They're the three DNS-based email authentication standards. SPF lists servers allowed to send for your domain, DKIM cryptographically signs messages, and DMARC tells inbox providers what to do when checks fail. Gmail and Yahoo require all three for bulk senders — and reward them for everyone else.
Not automatically. Most offer at best a manual domain checker. NimblyMail runs the full six-pillar audit weekly, keeps 7-day snapshots, and adapts the checks to whichever mailer is active.
You get the failing pillar, the reason, and a one-click fix — for DNS issues, the exact SPF include, DKIM record, or DMARC policy to publish at your DNS provider.
