How to Convert an Image template into HTML Code Using Gemini for Email Invitation Branding

Customizing your Email Branding header or layout in Customer Alliance is a great way to maintain brand consistency. If you have a design mock-up (such as a JPEG or PNG file), you can use Google Gemini to convert that image into email-ready HTML code.


Step 1: Upload Your Image Design to Gemini

  1. Open Google Gemini (gemini.google.com) - free version
  2. Click the + / Image Upload icon in the prompt box.
  3. Select and upload your design screenshot, logo layout, or email header mockup.

Step 2: Use the Email-Specific Gemini Prompt

Email clients (like Outlook or Gmail) process HTML differently than modern websites. Copy and paste the prompt below into Gemini along with your image upload to get email-compatible code:

Copy & Paste Prompt:

"Act as an email template developer. Convert the attached image into clean, email-safe inline HTML and CSS. Use table-based layouts (<table>, <tr>, <td>), inline CSS styles, and ensure images use <img> tags with explicit alt text and inline dimensions. Do not use external CSS or JavaScript. Wrap everything in a standard block."

Step 3: Copy the Generated HTML Code

  1. Once Gemini processes your image, locate the generated code block.
  2. Click the Copy Code button at the top-right of the code snippet in Gemini.

Step 4: Paste Code into Customer Alliance

  1. Log in to your Customer Alliance dashboard.
  2. Go to Settings > Invitation Emails (or your designated template/signature editor).
  3. Switch the editor from standard visual mode to HTML / Source Code view (usually indicated by a <> icon).
  4. Paste your copied HTML code into the box.
  5. Replace any placeholder image URLs (e.g., src="your-image-url.jpg") with publicly hosted links to your actual brand assets.
  6. Click Save and send a Test Email to ensure your design renders properly across devices.
