Menu Email Header Design Guide

Extract your restaurant's primary colors from the printed menu using Adobe Color's "Extract Theme" feature (https://color.adobe.com). Record hex codes and feed them into DesignLumo’s Brand Kit so every AI‑generated header automatically applies the exact palette. Verify contrast ratios above 4.5:1 with WebAIM’s Contrast Checker to ensure readability on both desktop and mobile. Document the palette in a shared Google Sheet and lock it down as a visual style guide for the entire marketing team.

Search Unsplash (https://unsplash.com) for high‑resolution dishes, filtering by orientation "landscape" and keyword "menu". Download images at 3000 px width, then compress to under 150 KB with TinyPNG to meet email size limits. Add descriptive alt text like "spicy chicken tacos – seasonal special" to boost accessibility and SEO. Store the vetted assets in a shared Dropbox folder, tagging each with season and menu category for quick retrieval during weekly campaigns.

Choose a primary serif font for dish names and a clean sans‑serif for sub‑copy from Google Fonts (https://fonts.google.com). Apply a size ratio of 1.5 (e.g., 36 pt headline vs 24 pt tagline) and a line‑height of 1.2 for legibility. In DesignLumo, place each text element on its own editable layer, lock the headline position, and set the color to the brand's secondary hue. Run a quick contrast test (minimum 4.5:1) and export the layered PSD for future tweaks.

Prompt DesignLumo with: "Create a 600 × 200 px email header for a Mediterranean restaurant, olive‑branch motif, brand colors #006644 and #F2E8D5, space for headline." The AI returns a fully layered PSD in seconds. Review each layer—background, motif, text placeholder—adjust colors via the Brand Kit, and export a PNG for immediate email use. Track generation time (average 12 seconds) to quantify workflow savings versus manual Photoshop builds.

Craft a Midjourney V5 prompt: "Mediterranean restaurant email header, olive branch, #006644, #F2E8D5, space for headline, --ar 3:1 --v 5" and run it with a batch size of 5. Download the four JPEGs, then import each into DesignLumo's "Convert to Layers" feature to extract vector outlines. This hybrid workflow yields five unique, editable concepts in under 10 minutes, cutting creative iteration time by 70% compared to manual sketching.

Upload the PNG from DesignLumo into Canva Pro (https://www.canva.com). Use the "Remove background" tool to isolate the motif, then add animated GIF stickers for limited‑time offers. Apply your saved Brand Kit to instantly sync colors and fonts. Export the final header as a WebP file (max 100 KB) to reduce load time. Record the total edit time—typically 3‑4 minutes—to illustrate efficiency gains over traditional desktop software.

Create two header versions: one with a bold headline, another with a subtle tagline. Upload both to Litmus (https://www.litmus.com) and embed them in identical email sends to a 5% sample of your list. Measure open‑rate lift and click‑through rate (CTR) over a 48‑hour window; aim for a minimum 5% improvement. Document the winning variant in a shared Airtable and schedule it as the default for the next campaign cycle.

Ensure header height collapses to ≤120 px on screens <600 px wide. Add CSS media queries in your email template: "@media only screen and (max-width:600px) { .header-img { height:auto; max-height:120px; } }". Validate with Email on Acid (https://www.emailonacid.com) across 30 devices, confirming the image file size stays under 100 KB after compression. Log any failures in a Google Sheet to track compliance trends over time.

Export weekly ESP reports (open, CTR, header‑click) as CSV and connect them to Google Data Studio (https://datastudio.google.com). Build KPI tiles for "Header Engagement Rate" (clicks ÷ opens) and set conditional color alerts for drops >10%. Schedule an automated email of the dashboard every Monday, enabling the marketing manager to spot under‑performing headers within 24 hours and iterate quickly.
