Email Infrastructure Consultant · Mailchimp Pro Partner
Some of your emails aren't reaching inboxes. Right now.
Open rates don't warn you. Bounce reports lag. By the time spam placement becomes visible,
the infrastructure damage is already accumulating. SPF gaps, DKIM misconfigurations, dirty lists, broken
warmup — these run silently until they don't.
I fix the system — not the symptoms. Infrastructure-first, before content, before campaigns.
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.
SPFDKIMDMARCIP WarmupDNS
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.
ValidationBounce removalRe-engagementSegmentation
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 renderingOutlookSpam scoringLitmus 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.
Most email consultants start at the dashboard. I start at the
infrastructure.
Before email marketing, I spent years managing network and server infrastructure for major
ISPs. I understand email from both sides of the filter — not just what the sending platform
sees, but what the receiving infrastructure actually evaluates when your message arrives.
That background is why I diagnose at the infrastructure layer first. SPF, DKIM, and DMARC aren't
marketing concepts to me. They are DNS and network protocols — and I've configured them at a scale most
email marketers never touch.
Combined with a Computing & Information Systems degree from London Metropolitan
University and Pro Partner certification from Mailchimp, this is the difference between someone
who runs campaigns and someone who builds the system the campaigns run on.

Case studies
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.

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. No blacklisting. System documented and handed over.

12GB+ campaign asset infrastructure — no delivery degradation
Heavy asset campaigns fail in predictable ways: slow load times, image blocking, spam scoring from hosted

correctly, quickly, and without triggering content filters. The infrastructure still runs without ongoing
maintenance — documented, stable, and client-managed.

Free Tool
Check your email authentication records —
instantly.
SPF, DKIM, and DMARC failures are invisible until they cost you inbox placement.
Query your domain's live DNS records and see exactly what's missing, misconfigured, or passing — no account
needed, no data stored.
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 fit?
GOOD FIT
✓You send 5,000+ emails per month and

exactly why
✓You're migrating to a new ESP and can't
afford reputation loss
✓Large list (10k+) not cleaned in over a
year
✓DNS authentication set but never verified

✓You need Outlook-compatible HTML
templates that actually work
NOT THE RIGHT FIT
–You need someone to write email copy or content
–You want quick fixes without understanding what was broken
–Your list is under 500 contacts and deliverability isn't a problem yet
–You're looking for the cheapest option — this work is priced on

Common questions
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.

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.
Why vibe coding and vibe mailing destroys infrastructure at scale. Real engineers with mental models are
pulling 6–24 months ahead. Here's what separates them.
If your campaigns are landing in spam, your bounce rate is climbing, or you're setting up new sending
infrastructure — that's where I start. Not with templates. With diagnosis.
