Formal Sales Email Template

I need a clean, professional email template I can reuse for sales-oriented campaigns that promote our products and offers without compromising our brand’s formal tone. The layout has to place our logo and full contact details prominently, while keeping the copy area flexible so I can swap in new promotional text as needed.

Core parameters
• Tone: formal and professional throughout; no casual language.
• Purpose: drive sales and promotions, so the design should guide readers toward a clear call-to-action button.
• Branding: feature our logo at the top and full contact details in the footer. I am not planning to include product images, discount codes, or testimonials right now, but the structure should allow for those sections to be added later if required.
• Technical: responsive HTML/CSS that renders well in Outlook, Gmail, Apple Mail, and mobile clients; inline CSS preferred; no external assets that could get blocked.

Deliverables
1. Editable HTML file ready to upload into Mailchimp (or any ESP that accepts raw HTML).
2. A quick read-me explaining where to change headline, body text, button link, and color accents.
3. Screenshot proof from at least two major email clients confirming the layout holds.

Acceptance criteria
• All branding elements display correctly with images turned on or off.
• Text remains legible on screens 320 px wide and above.
• Final code passes Mail-Tester spam check above 9/10.

Once the template meets those points I can sign off quickly, so feel free to let me know if you need logo files or brand colors before you begin.
