## Context

As part of automating the welcome email process for merchants signing up to our dashboard, we need to create a visually appealing, fully responsive email template based on the design provided in the Figma file. The template will serve as the welcome email for merchants, replacing the current manual process, and must align with our brand guidelines.

  #### **Requirements:**

  - Follow the design provided in the Figma file: [Figma Link](https://www.figma.com/design/lhmTvW2vuc2p5B4ZvsEOTw/Email-Tempalte-Design?node-id=0-1&t=OKWmXqVOsidKUk7y-1)
  - Utilize existing assets (images, logos, icons, etc.) found in the figma.
  - Ensure the template is fully responsive and compatible with major email clients (e.g., Gmail, Outlook, Apple Mail).
  - Include all the design elements such as header, body content, call-to-action button, and footer as outlined in the Figma file.
  - Write clean, maintainable, and well-documented code.

  #### **Acceptance Criteria:**

  - Email template developed according to the Figma design.
  - The template is responsive and displays correctly across major email clients.
  - The design aligns with the brand style guidelines.
  - Code is properly commented and documented.
  - A preview of the email template is provided.

  #### **Additional Notes:**

  If you have any questions regarding the design or assets, please drop a message in our Community Channels
