What is an Email Signature Generator?
An Email Signature Generator is a professional tool that helps you create custom, branded email signatures that appear at the bottom of your outgoing emails. Unlike simple text signatures, HTML email signatures can include logos, social media icons, banners, and professionally formatted text that enhance your professional image.
Our generator creates signatures that are compatible with all major email clients including Gmail, Outlook, Apple Mail, Yahoo Mail, and Thunderbird. Whether you're a business professional, entrepreneur, or freelancer, a professional email signature builds credibility and provides essential contact information.

2. Optimize for Mobile
Over 60% of emails are opened on mobile devices. Ensure your signature is responsive:
@media only screen and (max-width: 600px) {
.signature-table {
width: 100% !important;
}
.signature-image {
width: 80px !important;
height: auto !important;
}
}
3. Use Web-Safe Fonts
Stick to fonts that are available across all platforms:
- Safe Choices: Arial, Helvetica, Georgia, Times New Roman, Verdana
- Good Fallbacks: 'Segoe UI', Tahoma, Geneva, sans-serif
- Avoid: Custom fonts unless using web fonts with fallbacks
4. Image Optimization
Images in email signatures should be:
- Small file size: Under 50KB if possible
- Proper dimensions: Logo: 100-150px wide, Profile photo: 80-100px square
- Alt text included: For accessibility and when images are blocked
- Hosted reliably: Use permanent hosting (not local files)
5. Essential Elements to Include
- Full Name: Your complete name as you want to be addressed

Frequently Asked Questions (FAQ)
Why does my signature look different in Outlook?
Outlook (especially desktop versions) uses Microsoft Word's rendering engine, which has limited CSS support. It's best to use table-based layouts, inline styles, and avoid modern CSS properties. Our generator creates Outlook-compatible code by default.
How do I host images for my signature?
You have several options: 1) Use your company website/server, 2) Use cloud storage (Google Drive, Dropbox with public links), 3) Use image hosting services (Imgur, Cloudinary), or 4) Use our temporary hosting (for testing). For permanent signatures, use reliable, permanent hosting.
Can I add a banner or promotional image?
Yes, you can add banners, promotional images, or call-to-action graphics. Keep them small (maximum 300px wide) and ensure they don't make your signature too large. Remember that some email clients block images by default, so include alt text.
How often should I update my email signature?
Update your signature when: 1) You change roles or companies, 2) Contact information changes, 3) Company branding updates, 4) Adding/removing social media accounts, 5) Seasonal promotions change. Regular updates ensure your signature remains accurate and professional.
Is it safe to include personal information?
Include only professional contact information you're comfortable sharing publicly. Avoid personal phone numbers or addresses. Consider using a business phone line and professional email address. Never include sensitive information like home address or personal social media.
