Bi-Weekly Fishing Email Template

I run a small charter-boat operation and send my customers a short “Fishing Conditions” update every two weeks. I need a clean, reusable email template that works flawlessly inside Yahoo Mail.

Core requirements
• Two clearly marked image placeholders (I should be able to drop in fresh photos with a simple copy-paste).
• One main text block where I can paste AI-generated or handwritten reports without breaking the layout.
• Subtle nautical styling that still keeps the focus on the content—think blues, whites, and room for my logo.
• Responsive HTML/CSS so the message looks just as good on mobile as on desktop Yahoo inboxes.
• Simple instructions telling me where to paste images/text and how to change colours or headings if I want.

I’m not set on a single-column, two-column, or grid approach—please propose what will read best for customers who usually skim on their phones. As long as it’s intuitive for me to update each fortnight, I’m happy.

Final deliverable
1. The finished HTML file (or a shareable Yahoo-compatible template).
2. Any supporting assets (inline CSS, images, fonts if needed).
3. A brief read-me explaining where to edit.

Looking forward to a straightforward, plug-and-play solution that lets me keep anglers excited about their next trip.
