Email HTML Stripped by Email Clients
You designed beautiful HTML emails for your Replit app, but when recipients open them, the formatting is completely wrong. Images are missing, layouts are broken, CSS styles are stripped, and in some cases the email appears as plain text with raw HTML tags visible.
Email clients (Gmail, Outlook, Apple Mail, Yahoo) are notoriously aggressive about stripping HTML and CSS that they consider unsafe. Unlike web browsers, email clients do not support modern CSS, JavaScript, or many standard HTML features. Each client strips different things in different ways.
AI-generated email templates almost always use modern web CSS (flexbox, grid, external stylesheets, CSS variables) that email clients will strip or ignore entirely, leaving your carefully designed emails looking broken.
Error Messages You Might See
No error messages — emails send successfully but render incorrectly
Images show as broken icons in email
Email appears as plain text with HTML tags visible
Formatting completely different in Outlook vs Gmail
Common Causes
- External CSS stylesheets — email clients strip <link> tags and only support inline styles
- Modern CSS features — flexbox, grid, CSS variables, and media queries are not supported by most email clients
- JavaScript in emails — all JavaScript is stripped by every email client
- Background images via CSS — many clients ignore CSS background-image properties
- Unsupported HTML tags — email clients strip <div> positioning in favor of table-based layouts
- Image hosting issues — images linked from localhost or Replit dev URLs are not accessible from email clients
How to Fix It
- Use inline CSS only — put all styles in style="" attributes directly on HTML elements, never in <style> tags or external files
- Use table-based layouts — email HTML requires <table> elements for layout, not div/flexbox/grid
- Use an email framework — libraries like MJML, React Email, or Maizzle generate email-safe HTML from modern syntax
- Host images externally — use Cloudinary, S3, or your CDN for email images with absolute HTTPS URLs
- Test across clients — use Litmus or Email on Acid to preview your emails in Gmail, Outlook, Apple Mail, and Yahoo
- Include a plain text fallback — always send a multipart email with both HTML and plain text versions

I’ve watched the tech landscape evolve over the last decade—from the structured days of Java Server Pages to the current "wild west" of Agentic-driven development. While AI can "vibe" a frontend into existence, I specialize in the architecture that keeps it from collapsing.
My expertise lies in the critical backend infrastructure: the parts that must be fast, secure, and scalable. I thrive on high-pressure environments, such as when I had only three weeks to architect and launch an Ethereum redemption system with minimal prior crypto knowledge, turning it into a major revenue stream.
What I bring to your project:
Forensic Debugging: I don't just "patch" bugs; I use tools like Datadog and Explain Analyzers to map out bottlenecks and resolve root causes—like significantly reducing memory usage by optimizing complex DB joins.
Full-Stack Context: Deep experience in Node.js and React, ensuring backends play perfectly with mobile and web teams.
Sanity in the Age of AI: I bridge the gap between "best practices" and modern speed, ensuring your project isn't just built fast, but built to last.

Jacek Rozanski
Senior PHP/Symfony developer and DevOps engineer with 20+ years of professional experience, running opcode.pl (web development agency, est. 2004).
Day job: I'm the sole backend developer at merketing company where I own and maintain 11 PHP/Symfony microservices on AWS (ECS Fargate, RDS, S3, CloudFront), handle the full CI/CD pipeline (Bitbucket Pipelines, Docker), and manage monitoring with Sentry and CloudWatch. These services handle high request volumes in production every month.
What I bring to AI-built apps:
- I audit and fix security issues (OWASP methodology), performance bottlenecks, and architectural problems in codebases generated by Cursor, Claude Code, Lovable, Bolt, and v0
- I refactor AI-generated prototypes into production-grade applications with proper error handling, testing, and clean architecture (SOLID, DDD, hexagonal architecture)
- I set up the infrastructure AI tools don't touch: AWS hosting, CI/CD pipelines, automated deployments, database optimization, monitoring, and alerting
- I integrate external services: payment providers, email systems, partner APIs, SSO/auth
Tech stack: PHP 8.x, Symfony, React, Next.js, PostgreSQL, MySQL, Docker, AWS (ECS, RDS, S3, SQS/SNS, CloudFront), Terraform, Supabase. I also use AI tools daily (Claude Code, Cursor) in my own workflow, so I understand both the strengths and the gaps in AI-generated code.
Based in Poland (CET timezone). Available for async work and calls during EU/US business hours.

Get HelpFrequently Asked Questions
Why does my email look fine in Gmail but broken in Outlook?
Outlook uses Microsoft Word's rendering engine for HTML emails, which has extremely limited CSS support. You must use table-based layouts and inline styles for Outlook compatibility.
Can I use CSS flexbox in emails?
No. Flexbox, grid, and most modern CSS features are not supported by major email clients. Use HTML tables for layout and inline styles for formatting.
What is the easiest way to create email-safe HTML?
Use MJML (mjml.io) — it lets you write simple markup that compiles to email-safe HTML with table layouts and inline styles automatically.
