I will audit and fix your HTML email templates for dark mode and accessibility

About this gig
Is your email "breaking" in Dark Mode? Are you losing subscribers because your content isn't accessible?
With 80% of mobile users on Dark Mode, unoptimized emails risk invisible logos and poor readability. Accessibility is now a professional standard, not an option.
I will technically audit and fix your HTML templates to ensure they render perfectly and remain accessible for every recipient.
What I Will Fix & Optimize:
Dark Mode: CSS overrides and [data-ogsc] for perfect color adaptation.
Visibility: Glow effects and padding to keep dark logos visible on dark backgrounds.
Accessibility: Semantic tags, ARIA labels, and WCAG-compliant color contrast.
Outlook: Hand-coded MSO tags for stability across all Outlook versions
The Audit Process:
Testing: Full rendering scan across 50+ clients (Gmail, Outlook, Apple Mail)
Review: Deep dive into code to find hard-coded colors and table errors
Validation: Final implementation and testing via Litmus/Email on Acid.
Why Choose Me?
Expert HTML Coder: Expert in CSS/HTML specifically for email
Growth-Driven: Optimized for higher reach and readability (Dark Mode).
Universal: Supports Klaviyo, Mailchimp, HubSpot, and more.
Thanks

FAQ
Why does my logo disappear in Dark Mode?
Most logos have dark text. When an email client flips the background to black, the dark text becomes invisible. I fix this by using specific CSS targeting or optimized image assets.
What is "Email Accessibility"?
It means ensuring that people with visual impairments can "read" your email using screen readers. This involves specific HTML attributes that most standard templates ignore.
Do you provide the source code?
Yes, you will receive the fully optimized HTML file ready to be uploaded to your ESP (Email Service Provider).
Will these fixes work in Outlook?
Outlook is notoriously difficult with Dark Mode. I use "Targeted CSS" and ghost tables to ensure the best possible rendering for Outlook users.
