Professional Email Signature Best Practices
To maximize the impact of your Gmail signature, follow these best practices:
Keep it concise: Limit your signature to 4-6 lines. Less is more.
Use professional fonts: Stick with Arial, Helvetica, or Georgia for universal compatibility.
Include essential contact info: Name, title, email, phone, and website are the basics.
Add a call-to-action: Link to your portfolio, book a meeting, or direct to your website.
Maintain brand consistency: Use your company colors, fonts, and logo.
Test across platforms: Preview your signature in Gmail, Outlook, Apple Mail, and mobile clients.
Avoid excessive formatting: Too much color or size variation looks unprofessional.

Dark Mode Signature Compatibility
If you use Gmail's dark mode, your signature should adapt automatically. However, certain colors may not display well in dark mode. To ensure compatibility:
- Test your signature in both light and dark mode
- Use neutral colors that work in both themes
- Avoid pure white text or backgrounds
- Consider using a signature generator that supports dark mode
