Common Mistakes to Avoid

1. Using a Low-Resolution Image

Solution: Use a high-resolution image (at least 300 DPI) for your logo or photo.

2. Overusing Fonts and Colors

Reason: A cluttered signature with too many fonts, colors, and graphics is difficult to read and looks unprofessional.
Solution: Stick to a simple design with one or two fonts and a limited color palette.

FAQs

What's the ideal size for an email signature image?
Aim for a small file size (under 50KB) and dimensions around 400-600 pixels wide. Larger images can cause blurring and slow loading times. Use a high-resolution image and compress it for optimal results.
How do I prevent my signature from looking blurry on mobile devices?
Use vector graphics (like SVGs) instead of raster images (like JPGs or PNGs). Vectors scale without losing quality, ensuring your signature looks sharp on all screen sizes. Also, test your signature on different devices and email clients before sending it out widely.
What information should I include in my email signature?
Keep it concise! Include your name, title, company, contact information (phone number, email address, website), and optionally a professional headshot or company logo. Avoid excessive links or social media icons unless absolutely necessary for your role.
