Deliverability Audit

Find Out Why Your Emails Are Landing In Spam

A full diagnostic of your existing domains, authentication, and sender reputation, followed by hands-on remediation. Not a checklist you have to interpret yourself. A plain-English report and a fixed problem.

Diagnose the Real Problem, Then Fix It

Dropping open rates, emails landing in spam, or a domain you suspect is blacklisted usually comes down to a handful of root causes: broken authentication, sending-reputation damage, or list quality problems. We run the same diagnostics deliverability specialists use, explain exactly what's wrong in plain language, and fix what's fixable directly instead of handing you a checklist and leaving.

Sound familiar?

  • Your open rates have dropped and you don't know why
  • Emails are landing in spam or promotions instead of the primary inbox
  • You suspect a domain or IP is blacklisted but haven't confirmed it
  • SPF, DKIM, or DMARC were set up once and never checked again

What You'll Get

A clear, documented answer for why deliverability dropped, not a guess

Authentication and DNS records fixed and verified, not just flagged

Blacklist delisting handled directly where a listing is confirmed

A concrete plan for the sending practices that caused it, so it doesn't happen again

Scope

Exactly What You're Getting

Included

  • Full written deliverability audit report (authentication, reputation, blacklists, list health, sending patterns)
  • SPF, DKIM, and DMARC corrected and verified
  • Blacklist delisting requests submitted where a listing is confirmed
  • Inbox placement re-test after remediation

Not Included

  • Guaranteed inbox placement (no agency can promise this; ISPs make the final call)
  • New domain or mailbox setup (see our Cold Email Infrastructure service for that)
  • Ongoing monitoring beyond the included follow-up re-test

How It Works

Our Process

1

Diagnose

We run a full audit across authentication (SPF/DKIM/DMARC), sender reputation (Google Postmaster, Microsoft SNDS), blacklists, list health, and sending patterns.

2

Report

You get a plain-English report: what's actually broken, what's a risk factor, and what's fine.

3

Remediate

We fix what's fixable directly (DNS records, blacklist delisting requests, list hygiene) and advise on the rest.

4

Verify

We re-test after changes propagate to confirm inbox placement has actually improved, not just that the checklist is done.

The Details

Timeline, Requirements & Pricing

Timeline

Most audits and remediation are completed within 1-2 weeks, though DNS changes can take up to 72 hours to fully propagate before we can re-test.

What We Need From You

  • Access to your domain's DNS settings (or a contact who can make changes)
  • Access to your email sending platform/ESP
  • Recent send data if available (bounce rates, complaint rates, engagement)

Pricing

Priced based on how many domains or mailboxes need auditing and the scope of remediation required, confirmed exactly in your proposal after the discovery questionnaire.

Our Guarantee

If It Doesn't Work As Scoped, We Fix It

2 Rounds of Revisions

Included before final delivery. Additional rounds beyond that are scoped and billed separately.

30-Day Support Window

For 30 days after delivery, we fix anything that doesn't work as scoped, at no charge.

Built to Match What We Scoped

If what we deliver doesn't match what was agreed in the proposal or configuration, we make it right.

Frequently Asked Questions

No legitimate agency can guarantee inbox placement since ISPs make that call, not us. What we can do is fix every technical and reputation issue within our control and give you a clear picture of what's driving the problem.
