Signature Not Showing Up
Symptoms: Your signature doesn't appear when composing new emails.
Solutions:
- Make sure you've saved the signature in Gmail settings (Settings → See all settings → General → Signature)
- Check that you've selected "Insert signature before quoted text in replies" if needed
- Verify you've selected the correct signature from the dropdown menu at the bottom of your compose window
- Clear your browser cache and reload Gmail
- Try using Gmail in an incognito/private browsing window to rule out extension conflicts
Images Not Displaying
Symptoms: Your logo or profile photo appears as a broken image icon.
Solutions:
- Image Too Large: Gmail has a 10KB per-image limit. Compress your images before uploading.
- Base64 Encoding Issue: Gmail supports base64 encoded images, but they must be under the size limit.
- External Links Blocked: If using external image URLs, ensure they're publicly accessible and use HTTPS.
- Recipients Can't See Images: Recipients with "Display images" disabled won't see your images. Include important text outside of images.
- Try uploading a smaller, optimized version of your logo (recommended: 100x100px or smaller)
Formatting Gets Messed Up
Symptoms: Colors, fonts, or layout look different than expected.
Solutions:
- Gmail Strips Styles: Gmail removes some CSS styles for security. Use inline styles only.
- Font Changes: Gmail may override custom fonts. Stick to web-safe fonts (Arial, Times New Roman, etc.)
- Color Issues: Use hex colors (#000000) instead of named colors (black)
- Spacing Problems: Use table-based layouts instead of divs for better compatibility
- Test your signature by sending yourself a test email first
- Keep designs simple - complex layouts often break in email clients
Links Not Clickable
Symptoms: Social media icons or website links don't work when clicked.
Solutions:
- Ensure all links include the protocol (https:// or mailto:)
- Check that email addresses use mailto: protocol (mailto:email@example.com)
- Verify phone numbers use tel: protocol (tel:+1234567890)
- Make sure you're not accidentally wrapping links in plain text
- Test links by sending yourself an email and clicking each one
Signature Appears in Weird Places
Symptoms: Signature shows up in the middle of email threads or in replies.
Solutions:
- In Gmail settings, choose "Insert signature before quoted text in replies"
- This ensures your signature appears above the previous email thread
- For new emails, signature will always appear at the bottom of your message
- If using multiple signatures, make sure you've selected the right one for each email type
Mobile Gmail App Issues
Symptoms: Signature looks fine on desktop but broken on mobile app.
Solutions:
- Edit Mobile Signature Separately: Gmail mobile has its own signature settings. Go to Settings → Your account → Mobile signature
- Simplified Design: Use a simpler signature for mobile (less formatting, smaller images)
- Test on Mobile: Always test by sending yourself an email and checking it on your phone
- Image Scaling: Mobile screens are smaller - ensure images aren't too large (max 300px wide recommended)
Still Having Issues?
If you're still experiencing problems, try these general troubleshooting steps:
- Disable browser extensions temporarily to rule out conflicts
- Try a different browser (Chrome, Firefox, Safari)
- Clear your browser cache and cookies
- Check Gmail's status page to ensure there are no service disruptions
- Create a simpler version of your signature to identify what's causing issues
