How the Fix Works
Not every email template is built to the same standard, and those differences often become obvious only when rendering problems start to appear. Left unresolved, even small issues can hurt rendering, readability, and overall campaign performance.
We understand that you have already invested in the design and HTML build of your email template, but are not satisfied with how it performs. We are familiar with the many ways email templates are built and know how much quality can vary from one build to another.
Fixing unstable or poorly structured email code is not always the best solution. When a template has significant structural issues, we often recommend rebuilding the HTML from scratch to our coding standards.

Common Email Rendering Issues
Email template coding requires a different approach than web development. Email clients have strict technical limitations and periodically change how they render HTML. Delivering consistent results across major inboxes requires specialized experience. Below are some of the most common rendering issues.
-
Email template renders inconsistently across different email clients
Email-safe HTML and CSS improve client compatibility
-
CSS borders are restricted and may not render correctly
Alternative structures help reproduce the intended border appearance
-
Email template displays poorly on mobile devices
Responsive email coding adapts content for smaller mobile screens
-
In Dark Mode, text and logos become hard to see
Dark Mode fixes help restore readability and logo visibility
-
Email template breaks after content edits or updates
W3C validation helps detect structural HTML issues early
-
Background images don't display in Outlook
Hybrid techniques and VML code help maintain background image support
-
Fonts are replaced or display incorrectly
Web-safe fonts with reliable fallbacks ensure consistent display
-
Buttons and links lose styles or stop working properly
Inline styles and bulletproof coding preserve functionality
-
1px horizontal lines appear within content in Outlook
Technical QA helps identify and remove unwanted lines
-
Animated GIFs do not play in older versions of Outlook
A fallback static image preserves the essential message
-
HTML emails render incorrectly in Outlook: layouts and blocks break
A table-based structure helps keep blocks aligned and stable
-
Email template loads slowly on mobile devices
Image optimization reduces loading time on mobile

Frequently Asked Questions
Have questions before sending us a broken email template?
Browse the FAQ for clear answers on template review, minor fixes, full rebuilds, rendering issues, QA testing, final delivery, and when patching the code is no longer enough.
What do you need to review and fix my email template?
Send us your existing HTML email template and tell us what is not working as expected. If you already know where the issue appears, mention the email client, device, or ESP involved. We will review the template, confirm whether it needs a minor fix or a deeper rebuild, and recommend the best next step before moving forward.
Can you fix minor issues without rebuilding the template?
Yes. If the template structure is solid and the issue is limited, we can make a targeted fix and return a corrected HTML file. This may apply to spacing problems, broken links, or image issues. If the code is too fragile, we will explain why a rebuild may be safer before doing unnecessary patchwork.
When is it better to rebuild the template instead of patching the code?
A full rebuild is usually better when the template has deeper structural problems, keeps breaking after edits, or renders inconsistently across major email clients. In that case, patching small pieces may not solve the real issue. We can rebuild the HTML from scratch using your current design as the reference, giving you cleaner code, a more reliable template, and more confidence in the final result.
What will I receive with a rebuilt email template?
You receive a newly coded HTML email template based on your current design, with clean structure, optimized image files, and more reliable rendering across inboxes.
The rebuilt version removes hidden code issues, gives your team a stronger foundation for future edits, and is prepared for a smoother handoff to your team or client.
Will my rebuilt email template be tested before delivery?
Yes. If we rebuild your template, the HTML is coded from scratch using your current design as the reference. The rebuilt version is then tested across email clients using real devices and professional testing tools, so it is checked for reliable rendering before delivery. You can use 50% off email coding if you decide to rebuild it with us.
