Whether they're landing in spam, getting blocked, bouncing, or simply not being delivered—we'll identify the root cause, fix the technical issues, and help restore your cold email performance.

Emails sending fine but nobody's replying? That's a copy/targeting problem, not deliverability—see Campaign Audit instead.

Why This Happens

Most clients don't know why—here's the plain-English version.

Authentication Issues

Your domain isn't properly verified, so Google and Microsoft can't confirm the email is really from you.

Poor Sender Reputation

Too many bounces, spam complaints, or low engagement have quietly damaged how mailbox providers see your domain.

Incorrect DNS Setup

A single misconfigured record can silently break deliverability without any obvious error message.

Platform Configuration

Sending tool settings—volume, pacing, tracking—can trigger spam filters if set up wrong.

Sending Behavior

Sudden volume spikes or inconsistent sending patterns look suspicious to inbox providers.

Google & Microsoft Policy Changes

Both tightened bulk sender rules recently—setups that worked a year ago can silently break today.

Aged Infrastructure

Domains and inboxes that were never properly warmed or have been overused lose trust over time.

How We Diagnose

We inspect every layer of your sending infrastructure—not just one setting.

Authentication

We understand the difference between a marketing newsletter problem and a cold outbound problem.

Technical + Strategic Knowledge

We fix the DNS, and we understand why your specific sending pattern triggered it.

Done-For-You Implementation

On Recovery, we don't just tell you what's wrong—we fix it ourselves.

Simple Communication

No jargon dumped on you. You get a plain-English explanation and a plan.

Fast Turnaround

Most diagnoses complete within days, not weeks.

What We Commit To — And What We Don’t

We Guarantee The Repair

We guarantee the technical issues we find are properly repaired and retested. Inbox placement also depends on ongoing sending behavior, which we’ll advise you on.

Retested Before Handoff

We retest inbox placement to confirm the improvement, then hand you a report along with follow-up recommendations to keep things healthy.

An Honest Answer, Either Way

If we can’t pinpoint a clear cause, we’ll tell you honestly rather than invent a fix that won’t help.

We Don’t Upsell New Domains

Most issues are fixable on your existing domains. We only recommend new domains when reputation damage is severe enough that recovery would take longer than starting fresh.

Deliverability Audit

Fix The Problem — Then Keep It Fixed

Once the bottleneck is identified, the next step is usually cleaner data, stronger infrastructure, or a properly configured sending stack.

Frequently Asked Questions

Real questions from business owners dealing with deliverability problems.

Why did my open rates suddenly drop?

Almost always a deliverability issue—your emails are landing in spam or being blocked instead of reaching the inbox, so nobody's opening what they never received.

Why are my emails landing in spam?

Usually a mix of authentication problems, poor sender reputation, or sending patterns that look suspicious to Google/Microsoft's filters. We find the exact cause.

Can Google or Microsoft block my emails?

Yes, both. Google can restrict or block sending from domains that fail authentication, generate spam complaints, or trigger their bulk-sender policies. Microsoft runs its own reputation and policy systems, separate from Google’s, and can restrict sending independently.

Can you recover a burned domain?

In many cases, yes—reputation can be rebuilt. In severe cases (permanent blacklisting), a new domain may be the faster path, and we'll tell you honestly which situation you're in.

Do I need new domains?

Not always. Most issues are fixable on your existing domains. We only recommend new domains when reputation damage is severe enough that recovery would take longer than starting fresh.

Can I keep my existing inboxes?

In most cases, yes. We fix the underlying configuration and reputation issues rather than replacing your infrastructure.

Does this work with my sending platform?

Yes. Diagnosis and fixes are platform-agnostic—Instantly, Smartlead, ReachInbox, Lemlist, ManyReach, or custom SMTP setups are all supported.

How long does recovery take?

Most Recovery engagements complete within 72 hours of us confirming the diagnosis.

How long does just the Audit take?

Most audits are completed within 2-3 business days.

Can you fix authentication issues?

Yes—SPF, DKIM, and DMARC configuration is one of the most common fixes we implement.

What if you can't find the problem?

This is rare given how thorough our investigation is, but if we can't pinpoint a clear cause, we'll tell you honestly rather than invent a fix that won't help.

Do I need technical knowledge to work with you?

No. We explain everything in plain business language and handle all technical implementation ourselves on the Recovery plan.

What's the difference between the Audit and Recovery plans?

Audit gives you the full diagnosis and a fix roadmap you can implement yourself. Recovery includes the diagnosis plus us implementing every fix and retesting to confirm it worked.

Can I upgrade from Audit to Recovery later?

Yes—many clients start with an Audit and upgrade once they see the findings.

Will you touch my actual email content?

We review it for spam-trigger language and structural issues, but rewriting your messaging is a separate service (see Campaign Audit) if that's the deeper need.

Do you guarantee inbox placement after the fix?

We guarantee the technical issues we find are properly repaired and retested. Inbox placement also depends on ongoing sending behavior, which we'll advise you on.

What causes a sudden performance drop with no changes on my end?

Often it's a platform policy change (Google/Microsoft update their bulk-sender rules periodically) or gradual reputation decay that finally crossed a threshold.

Is this only for cold email, or does it work for any email sending?

We specialize in cold outbound email specifically—that's a different reputation and policy environment than transactional or newsletter email.

Do you check blacklists?

Yes, every domain and sending IP is checked against major blacklist databases as a standard part of the diagnosis.

What happens after the fix is implemented?

We retest inbox placement to confirm the improvement, then hand you a report along with follow-up recommendations to keep things healthy.

Can this happen again after you fix it?

It can if the same sending behaviors that caused it continue. Our recommendations include how to avoid a repeat.
