I can audit the newsletter for accessibility and dark mode risks, but I need the template details first. I will not call it "accessible" or "dark mode proof" at the end; I will tell you which checks passed and which to test.
- Text blocks (required). For each block (headline, body, buttons, footer): the text, font size (px or pt), bold or not, and the text and background colors as hex values. My sources do not say where Klaviyo shows these values, so please send them from wherever you have them (for example your brand guide or the template itself). Why: I compute each contrast ratio against WCAG 1.4.3 (at least 4.5:1, or 3:1 for large text), and that needs exact colors.
- Images (required). For each image: what it shows or does (for example "logo, links to homepage"), its alt text, and whether it has a transparent background. Why: the W3C alt decision tree gives different rules for decorative, linked and informative images, and transparent images are a common dark mode risk.
- Links (required): the visible text of each link.
Dark mode: I will list what to test in partial and full invert clients, since Litmus describes both; I cannot see how your email renders, so those are checks for your preview tool, not results.
