Email Marketing & Deliverability Consultant — Helping businesses build safer, more reliable email systems.

Protect your email infrastructure before small technical issues become expensive business problems.

Most email failures don't begin with catastrophic mistakes. They begin with small technical assumptions that nobody validated. Those assumptions silently accumulate until business growth, operational complexity, and time expose invisible structural weaknesses as expensive business failures. I help businesses improve inbox placement, automate customer journeys, and build reliable email systems by fixing the technical foundations behind successful email marketing.

Preventing those failures is always less expensive than recovering from them. I help e-commerce brands, SaaS platforms, and growing businesses identify the hidden risks in their email infrastructure before they turn into lost revenue and deliverability collapse.

Most businesses don't have an email marketing problem. They have an email infrastructure problem.

Poor authentication, DNS mistakes, automation errors, and hidden configuration issues silently reduce deliverability long before anyone notices.

Can you fix it yourself?

Often, yes.

one mistake affect your business?

Also yes. If email is critical for your business, even a small DNS or authentication mistake can reduce deliverability or interrupt important automations.


Hidden Problems I Usually Find

These infrastructure issues run silently in the background, eroding your sender reputation until your campaigns start underperforming.

✔ SPF configured incorrectly

Multiple SPF records or incorrect include statements that cause ISPs to instantly reject your emails as unauthorized.

✔ DKIM misalignment

Cryptographic signatures failing verification because selectors aren't configured or keys mismatch across platforms.

✔ DMARC policy never enforced

Leaving your policy at p=none forever, offering zero spoofing protection and failing compliance requirements.

✔ Automation silently stopped

API tokens expiring or webhook URLs changing, causing critical customer journeys to stall without error alerts.

✔ DNS records conflicting

Overlapping MX, CNAME, or TXT records that confuse mail servers trying to route or authenticate messages.

✔ Email authentication partially working

Passing some tests but failing bulk sender requirements for Yahoo, Google, and Microsoft inbox delivery.

"Invisible structural failures rarely begin with catastrophic mistakes. They usually begin with one small assumption that nobody validated."

— Discovery Builder Principle

Need a second opinion before implementing critical changes?

Let's review the decision before it becomes an expensive mistake.

Lifecycle & Automation

Reliable infrastructure is only valuable when it supports effective customer journeys. I help businesses build automated email workflows, segmentation strategies, and lifecycle campaigns that turn technical stability into measurable growth.

I build reliable email systems that protect and grow business communication

Deliverability failures always have a root cause.

Most tools diagnose symptoms. The real failure is usually at a different layer entirely. I trace problems to where they actually originate — then fix there first.

LAYER 01

Infrastructure

SPF, DKIM, DMARC, domain age, IP reputation, and warmup protocols. If the foundation is wrong, nothing else fixes it. Most senders skip this layer entirely.

SPF DKIM DMARC IP Warmup DNS
LAYER 02

List Health

Bounce rates, invalid addresses, low-engagement segments, and acquisition method. A dirty list will kill a clean infrastructure. The two problems compound each other.

Validation Bounce removal Re-engagement Segmentation
LAYER 03

Content Structure

Image-to-text ratio, HTML quality, rendering across 90+ clients including Outlook, and spam trigger patterns. Clean code matters as much as clean copy.

HTML rendering Outlook Spam scoring Litmus testing
LAYER 04

Sending Behaviour

Volume consistency, send cadence, segmentation by engagement tier, and stagger scheduling for large lists. Irregular volume is one of the most common causes of reputation damage.

Send cadence Volume stagger Engagement tiers Reputation

Most technical guides explain how to make a change. Very few explain the risks.

What assumptions must already be true? What hidden risks exist? When can a seemingly correct implementation still fail? Which situations require expert judgement instead of automation?

My work focuses on reducing decision risk before implementation. Because the most expensive mistakes usually begin as small, invisible assumptions.

Before email marketing, I spent years managing network and server infrastructure for major ISPs, understanding how receiving infrastructure evaluates inbound mail at the network level. Combined with a Computing & Information Systems degree from London Metropolitan University, I ensure every technical decision is backed by validation.

Before You Hire Anyone

Whether you work with me or someone else, make sure they explain:

✓ Business impact
✓ Technical risk
✓ Recovery plan
✓ Rollback strategy
✓ Validation process

What I Will Never Do

Responsible Delivery Standards

❌ Make technical changes without validation.
❌ Recommend solutions without explaining the risks.
❌ Ask you to trust me blindly.

My Working Principles

The Constitution

• Evidence before assumptions.
• Validation before implementation.
• Business before technology.
• Long-term stability before short-term fixes.


Which email problem needs fixing?

Mailchimp, Brevo, SendGrid, GoHighLevel — and the infrastructure beneath them. The platform changes. The system design principles don't.

Successful email marketing depends on more than campaigns. It requires reliable infrastructure, healthy data, effective automation, and continuous validation.

What fixing email infrastructure actually looks like.

Real systems, real constraints. These aren't use-case templates — they're actual problems that required building something that didn't exist yet.

Mailchimp Scale Custom Engineering

One million unique barcodes via Mailchimp — zero rendering failures

The client needed a unique scannable barcode in every single email sent to one million recipients. No native Mailchimp feature supports this. I designed a generation and merge system that produced unique barcodes at scale, embedded correctly in every recipient's email — without breaking deliverability or rendering across clients. Every barcode unique. Zero duplicates. 99%+ delivery.

Large-volume sends without a structured stagger schedule burn sender reputation fast. I built a segmented sending system that distributed volume across time windows based on engagement tiers — protecting IP reputation while maintaining consistent delivery performance across the full 70,000+ contact list. Stable reputation. No blacklisting. System documented and handed over.

Heavy asset campaigns fail in predictable ways: slow load times, image blocking, spam scoring from hosted links.

Every engagement follows the same diagnostic sequence.

I don't start with templates or campaigns. I start with infrastructure — and work outward from there.

01 /

Audit the current state

DNS records, authentication, list composition, bounce history, sending patterns. No assumptions. Everything checked against live data before a single recommendation is made.

02 /

Identify the actual failure point

Most deliverability problems have one root cause. I find it — infrastructure, list, content, or behaviour — before touching anything. Fixing the wrong layer wastes time and creates new problems.

03 /

Fix in order of impact

Infrastructure before content. List hygiene before volume changes. The sequence matters. A fix applied in the wrong order is just moving the problem somewhere else.

04 /

Test before going live

Litmus for rendering across 90+ clients. Seed testing for inbox placement. Spam scoring before every send. "Looks fine" is not a testing standard.

05 /

Document what was built

Every system I build gets documented. You should understand exactly how it works — not depend on me to run it. The goal is a system you can operate independently.

Is this the right time to bring in an expert?

YOU PROBABLY DON'T NEED ONE IF:

  • you're learning
  • it's a personal project
  • downtime doesn't matter

YOU PROBABLY SHOULD IF:

  • your business depends on email
  • customers aren't receiving campaigns
  • revenue is affected
  • authentication changes involve production DNS

Why businesses continue working with me

Deliverability isn't a one-time configuration; it's a discipline of stability and safety. Clients return because of my operating philosophy:

01

I explain the risks before making changes

Every proposal outlines potential business impacts, technical risks, recovery protocols, and validation strategies. No blind implementations.

02

I validate every critical configuration

We verify live DNS states, SPF alignments, and cryptographic keys using advanced query diagnostic steps before signing off.

03

I document what was changed and why

You receive full system documentation, allowing your team to operate independently without ongoing expert dependency.

04

I focus on long-term stability

I build infrastructures and warmups that survive e-commerce scaling, operational changes, and platform migrations, avoiding lazy shortcuts.

Answers to what most clients ask before getting started.

If your question isn't here, the first conversation is free.

Usually one of four reasons: broken or missing SPF/DKIM/DMARC, a list with too many invalid addresses or low-engagement contacts, HTML content with poor image-to-text ratio, or irregular sending volume. A proper diagnosis identifies the root cause before touching anything.
SPF specifies which servers can send on behalf of your domain. DKIM adds a cryptographic signature that receiving servers verify. DMARC tells those servers what to do when a message fails either check. All three need to be configured correctly in DNS and verified passing — not just present. A record that exists but is misconfigured is often worse than no record at all.

I hold Pro Partner status alongside three separate Mailchimp certifications: Foundation, Email Marketing, and Automation.
Yes. Brevo, SendGrid, and GoHighLevel are all platforms I work with regularly. The infrastructure and system design principles transfer across all of them. Platform choice matters less than how the system is built on top of it.
Drag-and-drop builders generate bloated markup that breaks in specific clients — particularly Outlook. Hand-coded HTML templates are built to a specific rendering standard, tested across 90+ email clients with tools like Litmus, and produce consistent results regardless of the recipient's mail client.
All engagements start with a diagnostic. Scope and pricing follow from what's actually broken — not a fixed menu. Deliverability audits are flat-rate and delivered within 5 business days. The first conversation is free — no pitch, just diagnosis.
Infrastructure fixes like SPF, DKIM, and DMARC setup typically take 1–3 days. List hygiene depends on list size but most projects complete within 3–5 days. Sender reputation recovery after blacklisting takes 2–6 weeks depending on sending volume and the ISPs involved.
Email list hygiene is the process of removing invalid addresses, hard bounces, spam trap addresses, and low-engagement contacts from your sending list. A dirty list — even a small percentage — raises bounce rates, triggers spam filters, and damages sender reputation over time.
Litmus for rendering across 90+ clients, seed testing for inbox placement, MXToolbox for DNS verification, and Google Postmaster Tools for sender reputation monitoring. Spam scoring runs before every send. "Looks fine" is not a testing standard.
IP warmup is the process of gradually increasing sending volume from a new or dormant IP to build a positive reputation with ISPs. It's needed when switching to a dedicated IP, after a long sending pause, or when migrating to a new ESP. Skipping warmup on high volume is one of the most common causes of deliverability collapse.
Yes. Gmail and Outlook blocks are usually caused by reputation issues — high bounce rates, missing authentication, spam complaints, or blacklisting. The fix starts with a full audit to identify which layer is causing the block, then infrastructure repair, list cleaning, and controlled re-engagement.
Small businesses often assume their sending platform (like Mailchimp or Brevo) handles deliverability. However, ESPs only provide the sending network; your sender reputation, DNS authentication, and list health are your responsibility. A dedicated expert with a background in ISP network engineering ensures your sending domain is properly authenticated, preventing your marketing campaigns from landing in the spam folder.
I perform a detailed query of your domain's live DNS records to pinpoint configuration issues, such as duplicate SPF records (which invalidate authentication), incorrect DKIM selectors, or missing DMARC policies. Once identified, I clean up conflicts, configure correct policy alignments, and verify passing states without disrupting your active email sending.
List cleaning pays for itself. Sending campaigns to invalid addresses, spam traps, or long-term inactive users damages your sender reputation and spikes bounce rates. Cleaning your list removes these toxic addresses, which immediately improves inbox placement and reduces your monthly ESP subscription fees by eliminating dead weight.
"Delivery" simply means the recipient's mail server accepted your email instead of bouncing it. "Inbox placement" is whether that email actually lands in the primary inbox or gets filtered into the Spam, Junk, or Promotions folder. My inbox placement services optimize sending infrastructure, reputation signals, and list segmentation to make sure your messages land where they are seen.
As a certified Mailchimp Pro Partner, my audits cover technical DNS authentication checks, audience segmentation, automation flow logic, and template rendering tests. I identify the exact bottlenecks causing campaigns to land in spam and provide a clear, actionable roadmap to restore and maintain your Mailchimp sending reputation.
