Welcome to Remint
15 years in. Here is what this publication delivers.
I have been designing and developing emails since before responsive layout was standard practice. Before dark mode was a production concern. Before AI entered the workflow.
In that time I have worked with brands across industries, built automation architectures from scratch, and watched a lot of confident advice age badly.
This publication shares what I have actually learned.
What we cover
Ten pillars guide the content here. Each maps to a real, active area of email practice.
Email Fundamentals. The mechanics everything else depends on: list health, permission frameworks, send cadence, and the baseline decisions that compound over time.
Flow Architecture. How to structure automated sequences that actually perform: welcome flows, post-purchase journeys, re-engagement campaigns, and the architecture connecting them.
Email Design Principles. Layout, visual hierarchy, and the patterns that make emails readable across devices and clients.
Copywriting for Email. Subject lines, preview text, body copy structure, and the specific techniques that move people from open to click.
Email Development. Most emails are built for best-case rendering. The technical reality is messier: Outlook’s Word-based engine, inconsistent dark mode implementations, and client quirks that no design tool warns you about. This pillar covers what you actually need to know to build emails that hold up.
Dark Mode. A dedicated pillar. Getting things right in email clients with dark mode is very tricky. This covers what actually works in production.
ESP Behaviour. How the major platforms operate behind the scenes: Klaviyo, HubSpot, ActiveCampaign, Mailchimp. What they do and how it shapes your results.
Deliverability. IP reputation, domain authentication, list hygiene, and the signals that determine inbox placement.
Analytics and Testing. What to measure, how to run tests that produce real signal, and how to build a testing practice that compounds over time.
Myths and Contrarian Takes. Email advice repeated until it becomes received wisdom. Most of it does not survive scrutiny.
And a new pillar that reflects where email production sits in 2026: AI in email production.
This is not about AI-generated campaigns or personalisation at scale. It is about the production workflow: image generation, code assistance, content scaffolding, and where AI tools remove genuine friction.
In my work with clients, the same pattern repeats. Simple fixes that would lift performance sit undone. Better content stays unwritten because the production cost feels too high. Money left on the table, consistently.
AI tools are changing that equation. This pillar covers where they help, where they fall short, and how to build a workflow that gets more out of every send.
Who this is for
Email designers and developers who want to sharpen their craft.
Marketing managers running email in-house who want to understand what is actually happening under the hood.
Agency operators building scalable email systems.
If you are looking for generic marketing content, this is not the place. Every post makes a specific, defensible point.
What to expect
Articles on each pillar, with real examples and sourced data.
Alongside the articles, I post Notes: shorter observations from active client work, quick findings from testing, and things that do not warrant a full piece. Think of them as working notes from a live practice.
New posts go out regularly. No filler, no padding.
