How the Audit Works
Take advantage of our technical audit focused on the HTML and CSS behind your email template. Whether it is hand-coded or built in your ESP, we review the structure and flag issues that can lead to broken layouts, clipping, and inconsistent rendering.
We test across real inboxes and devices, including Gmail, Outlook, and Apple Mail on desktop, tablet, and mobile. This helps catch issues that often appear only after sending, from spacing glitches and image scaling to dark mode conflicts and accessibility gaps.
Make sure your email template is not the weak link in your email marketing. Our audit helps uncover issues that can affect rendering, readability, and overall campaign quality before they impact a live send.

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 requesting a free email template audit?
Browse the FAQ for clear answers on HTML and CSS review, inbox testing, rendering issues, audit feedback, critical fixes, and what to do if your template needs a rebuild.
What will you check in my free email template audit?
Our free email template audit helps you understand whether your current template is reliable enough to use. We review the HTML, CSS, and key inbox behavior to catch issues that could affect layout, mobile display, Outlook rendering, or readability. You get clear feedback on what looks good, what may cause problems, and what to do next.
What email template issues can your audit help find?
The audit helps find problems that affect how your email looks or works, including broken layouts, Outlook rendering issues, mobile display problems, Dark Mode conflicts, image scaling, slow loading, or code that may break after edits. You will see the weak spots clearly, so you know whether the template is reliable or needs fixing.
Do you test the template in real inboxes during the audit?
Yes. We review the template in key inbox environments using real devices and a professional email testing platform. This helps us see how it behaves across desktop, mobile, webmail, and key clients like Gmail, Outlook, and Apple Mail. The goal is to catch rendering issues that may not be visible in a browser preview or inside your ESP.
What feedback will I receive after the audit?
You receive clear feedback from one of our email developers on the condition of your email template. We highlight the main issues, explain why they matter, and suggest the best next step. If the template looks solid, we will confirm that too, so you can move forward with more confidence.
What happens if the audit finds critical issues in my template?
If we find critical issues, we explain them clearly and recommend the best next step. In some cases, a few small fixes may be enough. If the template is too fragile, we can rebuild the HTML from scratch using your current design as the reference. You can use 50% off email coding if you decide to rebuild it with us.
