Email Deliverability

Get your mail
into the inbox.

Authentication is table stakes. The real work is reputation, operations, and recovery.

I run high-volume sending every day — dozens of domains, multi-IP rotation, reputation and bounce management at scale — so I diagnose from operating, not theory.

For You

This is for you if…

Authenticated, still in spam

SPF, DKIM, and DMARC all pass — yet your mail keeps missing the inbox.

Reputation dropped

Placement fell off after a dedicated-IP switch, a volume spike, or a bad campaign.

Proofpoint / blacklist blocks

Major filters or DNSBLs are rejecting or quarantining your mail.

Complex sending

Multiple sources, multi-IP rotation, subdomains — too tangled to manage alone.

High volume to manage

You send at scale and need someone who runs that kind of operation daily.

What I Do

Diagnose, recover, keep it there

The value isn’t the authentication — it’s knowing why authenticated mail still fails, and operating the fix.

01

Diagnose

Find why authenticated mail still hits spam — reputation, sending behavior, list/engagement, infrastructure. Pull DMARC reports to map every sending source.

02

Recover reputation

Rebuild damaged IP/domain reputation — warm-up, engagement-based ramp, per-ISP throttling (Gmail, Outlook, Yahoo), bounce and complaint suppression.

03

Untangle complex sending

Multiple sources, subdomain separation (marketing / sales / transactional), SPF 10-lookup limits, DMARC enforcement to p=reject, unsubscribe and suppression governance.

04

Blacklist & Proofpoint removal

Diagnose, fix the root cause, and submit delisting. Final approval is the operator’s, and staying off depends on sending practice — but the cause gets fixed.

05

Monitoring

Set up reputation monitoring — Google Postmaster, Microsoft SNDS, DMARC aggregate reports, blacklists — and watch it for you with alerting.

Any Platform

Wherever your mail sends from

SaaS or self-hosted — I work as an invited user, via API, with server access, or purely advisory if you’d rather not grant access.

How We Work

Two ways to engage

Start with a fixed-price audit and recovery. Stay on with an ongoing retainer if your sending needs continuous attention. Scoped to your case — message me for a quote.

Audit & Recovery

Start here
One-time, fixed price per scope

A health audit (authentication, reputation, inbox placement, sending sources) followed by a recovery plan with realistic timelines — reputation recovery is usually 2–4 weeks.

  • Full authentication review (SPF incl. 10-lookup, DKIM, DMARC, PTR)
  • Reputation assessment (Postmaster, SNDS, blacklists)
  • Root-cause diagnosis + fix in my area, advice on the rest
  • Engagement-based recovery / warm-up plan

Ongoing Partner

Hourly or monthly retainer

I take ownership of deliverability on your platform — monitoring, throttling, rotation, blacklist handling — as the inbox keeps changing. Best when volume is high and the setup needs continuous attention.

  • Continuous reputation & inbox monitoring
  • Per-ISP throttling and rotation tuning
  • Blacklist / Proofpoint response as it happens
  • Central dashboard across your domains and IPs
Scope

What’s mine, what’s yours

My side

  • Authentication & alignment (SPF / DKIM / DMARC / PTR / MTA-STS)
  • IP & domain reputation — warm-up, engagement-based ramp, per-ISP throttling
  • Sending-system operation, diagnosis, monitoring, recovery process
  • Blacklist & Proofpoint — diagnose, fix the cause, submit delisting

Your side

  • · Content, lists, and who you send to (I advise only)
  • · The decision to send, and sending volume
  • · Final reputation recovery, which depends on sending behavior
  • · Raw recipient data stays in your platform — I work from aggregate stats, not exported lists
Process

How it works

  1. 01

    Audit

    Authentication, reputation, inbox placement, and every sending source mapped from DMARC reports.

  2. 02

    Diagnose

    Pinpoint the root cause — sending behavior, list/engagement, or infrastructure.

  3. 03

    Fix & recover

    Correct what’s in my area, advise on the rest, and run an engagement-based recovery plan.

  4. 04

    Monitor

    Stand up monitoring (Postmaster, SNDS, DMARC, blacklists) with alerts — one-time, or ongoing.

FAQ

Frequently asked

My SPF, DKIM, and DMARC all pass. Why is mail still in spam?

Because authentication is not deliverability. Authentication proves who sent the mail; the inbox decision is driven by reputation — how recipients engage, how you send, your IP/domain history, and your infrastructure. Perfect green auth can still land in spam. I find the actual cause and fix it.

What platforms do you work with?

Any platform — Google Workspace, Microsoft 365, Salesforce/Pardot, Klaviyo, SendGrid, Instantly/Smartlead, or self-hosted (Postfix/Mailcow). For SaaS I work as an invited user or via API; for self-hosted, with server access. An advisory option (no access — you run the plan, I review) is available too.

How long does reputation recovery take?

Usually 2–4 weeks. Reputation is rebuilt through engagement-based sending, not a setting you flip. I’ll give you a realistic timeline after the audit.

Do you need my contact list?

No. I work from aggregate statistics and event logs inside your platform — I don’t take exported raw lists. Segmentation happens in your tool. If a task genuinely needs PII, it’s under a DPA, minimized, time-bound, and deleted.

Can you guarantee delisting from a blacklist?

I diagnose, fix the root cause, and submit the delisting request. Final approval rests with the listing operator, and staying off depends on your sending practice. I handle everything on my side and set you up so it doesn’t recur.

When should I NOT hire you?

If your setup is simple and stable, you probably don’t need me — self-service is enough, and I’ll tell you so. This is for senders with real volume or complexity. A good fit is the point.
