Built by Kartikey Gupta — email marketing practitioner. Not a generic AI wrapper. A diagnostic engine built on real-world deliverability expertise.

// How It Works

One form. Three minutes.
A report that actually tells you something.

No consultation calls. No waiting days for a reply. No vague "best practices" advice.

Step 01

Describe your campaign

Tell us your domain, ESP, what's going wrong, and paste your subject line and email body. No technical knowledge needed — the form guides you through it.

→
Step 02

The Lab runs diagnostics

Your submission is analysed against practitioner-level expertise — authentication records, deliverability signals, content patterns, and list health indicators. DNS records are verified live.

→
Step 03

Get your diagnostic report

A structured report with severity-rated findings and prioritised actions lands in your inbox within minutes. Every report includes a Lab Grade from A to F.

// What You Get

Everything a deliverability consultant
would tell you. For free.

Six diagnostic outputs in every report — specific to your campaign, not recycled advice from a blog post.

01

Authentication audit

SPF, DKIM, and DMARC verified live against your domain and ESP. Not a generic checklist — actual DNS record analysis.

02

Deliverability diagnosis

Inbox placement assessment based on your symptoms, ESP, sending history, and Google Postmaster reputation data.

03

Subject line review

Scored on clarity, relevance, urgency, curiosity, and personalisation. Spam-trigger phrases flagged individually.

04

Email body analysis

Content triggers, CTA effectiveness, HTML structure issues, and legal compliance gaps — all specific to your email.

05

Lab Grade (A–F)

A single grade that tells you where your campaign stands. Plain-English explanation of what it means and why.

06

Follow-up loop

Applied the fixes? Submit a follow-up with your Case ID. Get an updated diagnosis that tracks what improved and what's still off.

// Sample Report

Here's what a real
diagnostic report looks like

  • A Lab Grade from A to F — with a clear explanation of where your campaign stands and why
  • Five structured findings across authentication, deliverability, subject line, email body, and list health
  • Three prioritised action steps — ordered by what will move the needle most, not what's easiest
  • A practitioner insight that surfaces something you probably hadn't considered
  • A unique Case ID so you can track your case from Open through to Resolved

// Who This Is For

Built for people who manage
real email infrastructure.

Whether it's one domain or a portfolio of client sending environments — the Lab diagnoses at the level your situation requires.

SMB

Small business owners

Open rates dropping, emails landing in spam, and the usual advice isn't fixing it. You need a structured diagnosis — not another generic checklist from a blog.

Freelance

Freelance marketers

Managing campaigns across multiple client accounts, each with different ESPs and domain setups. The Lab gives you diagnostic output you can act on and present to clients with confidence.

Founder

Early-stage founders

Your onboarding or lifecycle emails aren't converting and you can't tell if it's authentication, content, or list quality. The Lab identifies the failure layer and tells you what to fix first.

Agency

Agencies

Managing email across multiple client domains with varying reputations and ESP configs. The Lab works as a rapid audit layer — triage campaign health across accounts without a full deliverability review each time.

// FAQ

Questions, answered plainly.

Is this actually free? +
Yes — completely free right now. No credit card, no trial, no hidden upsell. We're in beta and every submission helps us improve the diagnostic engine. Submit your campaign, get your report.
Is my campaign data kept confidential? +
Yes. Your data is never shared in identifiable form. Before anything is used for research or model improvement, all identifying information — name, domain, email address — is stripped out. You can also flag confidentiality directly in the form.
How long does the report take? +
Usually 2–5 minutes after you hit submit. Occasionally longer during high-volume periods, but always the same day.
Do I need to be technical to use this? +
Not at all. The form is built for marketers, not engineers. If you know which ESP you use and can describe what's going wrong, you have everything you need.
What is a Lab Grade? +
Every report includes a grade from A to F reflecting the overall health of your campaign setup. A means solid fundamentals with minor tweaks. F means something fundamental is broken and needs to be fixed before anything else will help.
How does the follow-up feature work? +
After applying your recommendations, submit a follow-up using your Case ID. The Lab analyses what changed, confirms what improved, and gives you the next set of actions. Your case stays open until the issue is resolved.
How is this different from asking ChatGPT to review my email? +
When you paste your email into a general AI, it gives you broad feedback with no structure or severity order. The Lab runs your submission through a practitioner-built diagnostic engine — it verifies DNS records live, interprets Google Postmaster data in context, applies ESP-specific logic, and weights findings by severity. Authentication failures are flagged before subject line tweaks. That kind of structured triage is what separates a diagnosis from a suggestion.
What if my issue doesn't fit the form options? +
Open-text fields let you describe edge cases in your own words — ESP migrations, transactional email issues, complex automations. If your submission falls outside what the engine can reliably assess, the report will say so directly rather than guessing.
