Run by Matt Brandenburg, a digital marketing operator with 30+ years of experience.
Start with the records a mail provider can see from the outside. The scan gives you a fast public snapshot, then shows what still needs human review.
Checks public DNS for MX, SPF, DMARC, common DKIM selectors, MTA-STS, TLS-RPT, and BIMI. No credentials required.
This is a preliminary public scan. The paid audit reviews alignment, headers, sender inventory, platform setup, and reputation context.
Paste the authentication lines from a delivered or spam-folder message. The analyzer runs in your browser and looks for SPF, DKIM, DMARC, sender domains, and obvious alignment clues.
Do not paste private message content. Authentication headers are enough for this quick check.
This is built for teams that need a specific repair path, not another vague score.
The audit is built for business owners, marketers, and operators who need a direct answer, not another dashboard.
SPF, DKIM, DMARC policy, alignment, reporting, and obvious record problems.
Blacklist exposure, DNS risk, sender-source inventory, and reputation clues.
Specific fixes ranked by risk and difficulty so the first repair step is obvious.
Every audit includes a plain-English summary, technical findings, exact DNS/provider recommendations, and a quote for hands-on repair if you want us to fix it.
A public scan can catch obvious issues. The audit turns scattered signals into a prioritized diagnosis.
| Question | Free checker | Email Deliverability Desk audit |
|---|---|---|
| Does it check public DNS? | Usually, yes. | Yes, plus alignment, sender inventory, risk level, and repair priority. |
| Does it explain what to fix first? | Usually vague or tool-specific. | Yes. The report is built around next actions, not just scores. |
| Does it account for your sending stack? | Usually not. | Yes. We map the tools sending as your domain and where alignment can break. |
| Can it turn into hands-on repair? | No. | Yes. The audit fee is credited toward the repair sprint if approved within 14 days. |

Checkout, domain, sending tools, and optional sample email headers.
DNS, authentication, alignment, sender requirements, and visible reputation signals.
Clear findings, recommended fixes, and an optional repair sprint quote.
You should know exactly what access is needed before any technical work begins.
The audit starts with public DNS data and customer-provided headers/screenshots if available. We do not need your mailbox password.
If you buy a repair sprint, use role-based DNS/provider access where possible. No shared admin passwords.
We diagnose and repair technical sender-trust issues. Inbox placement also depends on list quality, engagement, content, and volume.
The first purchase should feel clear, scoped, and low-friction.
A written 48-hour audit covering public DNS, SPF, DKIM, DMARC, sender alignment, visible sender-risk signals, and the first repair priorities. You get a plain-English summary plus technical recommendations your DNS, IT, or marketing team can use.
No. The audit starts with public records and customer-provided context. If headers or screenshots are needed, you can provide them without sharing a mailbox password.
No honest provider can guarantee inbox placement. We diagnose and repair technical sender-trust issues. Inbox placement also depends on recipient engagement, list quality, sending behavior, content, and mailbox-provider filtering.
A healthy public scan does not prove your real messages are aligned. The paid audit still checks real headers, sender inventory, platform configuration, and repair priority. If we cannot provide specific findings or a concrete recommendation, the audit is refundable.
