Professional Email Signature Design

I need a reusable email-signature block designed first, before we move on to any of the other brand assets on my list. The signature must feel professional and classic—clean lines, balanced typography, and no trendy gimmicks—so it stands up well across Outlook, Gmail, Apple Mail, and mobile clients.

Content that must appear:
• My name and job title
• Our company logo (I’ll supply an SVG and PNG)
• Direct contact information (phone, email, website, office address)

Please deliver:
1. A well-commented HTML file that renders perfectly without external CSS.
2. A matching fallback JPG/PNG for email apps that block HTML.
3. A quick-edit guide so my team can swap in future staff details without breaking the layout.

Testing in the latest versions of Outlook (Windows/Mac), Gmail (web & mobile), Apple Mail, and major iOS/Android mail apps is part of the scope; screenshots or a short Loom walkthrough will work as proof. Once this piece is complete and approved, I may open a follow-up project for social posts, web design tweaks, and custom realtor flyers, so consistency and buildability are key.
