How to Add an Email Signature in Gmail (Step-by-Step)

Gmail supports rich HTML signatures, but the paste step matters. If images or spacing break after saving, the issue is usually how the HTML was copied — not your design.

Quick setup with ProSignature

1. Create your signature in ProSignature (generator or templates)
2. Click Export → copy signature for Gmail
3. Open Gmail → Settings → See all settings → Signature
4. Paste → set as default → Save changes
5. Send a test email to yourself

Add signature in Gmail (desktop)

1. Open Gmail → Settings (gear) → See all settings
2. Scroll to Signature section → Create new
3. Paste your signature into the editor (use Copy Preview if available)
4. Set default signature for new emails and replies
5. Save changes and send a test email to yourself

Gmail on mobile

Mobile Gmail has limited signature editing. For best results, set up the full HTML signature on desktop first — it syncs to the mobile app for new messages.

Common Gmail signature problems

• Broken images → use hosted absolute URLs, not local file paths
• Blurry logo → upload at 2x size, display smaller
• Extra spacing → avoid nested tables with fixed heights
• Signature missing in replies → check default reply/forward setting
