Why Add a Logo to Your Email Signature?
Your company logo is the most recognisable element of your brand. Adding it to your email signature:
- Increases brand recognition by up to 80%
- Makes emails look more professional and trustworthy
- Creates visual consistency across your team
- Helps recipients instantly identify your company
Logo Size & Format Guidelines
📐 Recommended Size
Width: 80-200px
Height: Proportional (maintain aspect ratio)
Oversized logos look unprofessional and increase email size.
🖼️ File Format
PNG — Best for logos with transparency
JPG — Good for photos/headshots
SVG — NOT supported in email clients
📦 File Size
Keep under 50KB. Compress with TinyPNG or Squoosh. Large images slow email loading and may be blocked.
🌐 Hosting
Host on your website or a CDN (Cloudinary, Imgix). Use HTTPS URLs. Never embed logos as base64 — most clients block them.
Logo Placement Options
Left-aligned (Most Common)
Logo sits to the left of your contact details. Works well with horizontal logos. This is the standard business layout.
Top-aligned
Logo sits above your name and details. Great for wide/horizontal logos. Common in corporate signatures.
With Headshot
Headshot left, logo right (or vice versa). Popular for real estate, consulting, and executive signatures.
Icon-style
Small logo icon (40-60px) inline with your name. Subtle but effective. Works for clean, minimalist designs.
Common Logo Mistakes to Avoid
- Using an oversized logo — dominates the signature and looks unprofessional
- Embedding the logo (base64) — gets blocked by most email clients
- Using a low-resolution logo — looks blurry on retina displays
- No alt text — when images are blocked, recipients see nothing
- Linking logo to nowhere — always link your logo to your website
