Why your emails go to spam, and how we fix deliverability.

Spam placement has a handful of common causes and they are checkable in a sensible order. We diagnose authentication, sending reputation, list quality, engagement and content, fix the biggest cause first and verify the result. Nobody can promise inbox placement, but most problems have an identifiable cause.

How We Do It

A clear process you can follow along with.

1. Separate the symptoms

We find out whether mail bounces, lands in spam or just lands in a tab, and whether it affects one provider or all. Gmail-only trouble points to different causes than a problem at every provider.

2. Check authentication first

We verify SPF, DKIM and DMARC pass and align for every sending tool. Authentication failure is the most common and cheapest cause to fix.

3. Read reputation data

We review Google Postmaster Tools for your domain, any Microsoft and Yahoo sender tools, platform reports and blocklist lookups. We treat these as signals to interpret, not a score to chase.

4. Audit the list

We look at how addresses were collected, how old they are, hard bounce handling and how many recipients have not engaged in a long time. Mailing stale or purchased addresses is a major reputation risk.

5. Review content and sending patterns

We check for broken links, link shorteners, image-only emails, misleading subject lines, a missing unsubscribe link, and sudden volume jumps. We also check that the from name and reply address are real.

6. Fix in order and shrink risk

We repair authentication, suppress unengaged and bouncing addresses, and temporarily send only to your most engaged contacts to rebuild positive signals before widening the audience.

7. Verify and monitor

We confirm improvement through complaint trends, bounce rates and engagement over time, and set alerts so the next drop is caught early.

Mistakes We Help You Avoid

Common ways this goes wrong, and what we do instead.

Blaming subject line words

Trigger word lists matter far less than authentication, complaints and engagement.

Buying or renting lists

These addresses damage reputation and often break the law and platform terms. Confirm legal questions with your attorney.

Resending to everyone after a drop

Mailing the same unengaged list again makes reputation worse. Narrow first.

Trusting one seed test

Seed inbox tests are a rough signal and do not mirror real recipients.

Frequently Asked Questions

Why do my emails suddenly go to spam?

Common causes are a broken authentication record, a spike in complaints, mailing an old list, a volume jump or a change of platform. A structured check finds which applies.

Can you guarantee inbox placement?

No. Mailbox providers decide, and anyone promising otherwise is overselling. We reduce known risks and measure the effect.

Is the promotions tab the same as spam?

No. The promotions tab is still the inbox. It is a Gmail sorting choice, though stronger engagement can influence where messages land.
