Ever sent an email and noticed:
โ Broken images
โ Different fonts
โ Huge spacing issues
โ Misaligned icons
โ Mobile signatures looking completely different
You're not alone.
After migrating businesses to Microsoft 365, I still see one issue repeatedly:

It uses the Microsoft Word rendering engine, which means many modern HTML and CSS techniques simply don't work.

๐ถ๐:
โ
Use table-based layouts
โ
Avoid CSS Flexbox and Grid
โ
Use inline CSS only
โ
Set fixed image dimensions
โ
Host images securely via HTTPS
โ
Test on Outlook Desktop and Outlook Web separately
โ
Keep the signature lightweight

Designing an email signature like a website.
Email clients are not browsers.
๐ฃ๐ผ๐๐ฒ๐ฟ ๐๐ฎ๐ธ๐ฒ๐ฎ๐๐ฎ๐:
A professional email signature isn't just brandingโit's compatibility.
If your signature breaks in Outlook, your brand looks broken too.
P.S. I recently fixed an Outlook HTML signature issue that looked perfect everywhere except Outlook Desktop. The solution was surprisingly simple once the rendering limitations were understood.
