Add a vCard QR Code to Your Email Signature (Outlook & Gmail)

Why it belongs in your signature

A typical knowledge worker sends 35 emails a day. Every reply forwards your contact details to whoever reads it. Without a QR code, the only way someone saves you is to manually type your name and email into their address book, which almost no one bothers to do.

The QR code removes that friction. The recipient pulls out their phone, scans the bottom of the email on their desktop screen, and the OS offers a "Save Contact" prompt. Two seconds. No app, no signup, no copy-paste.

This matters most when your emails get forwarded inside an organization — the people you have never met but who end up making decisions about you. A signature QR turns those forwards into saved contacts.

Generate the QR code (the right way)

Use a vCard generator that outputs a PNG, not just an SVG. Email clients render PNG more reliably than SVG, and SVG sometimes gets stripped by spam filters.

• Open the dynamic QR code generator and pick vCard as the type
• Fill in name, mobile phone, email, organization, website, and photo URL
• Download the PNG at 200 pixels square (you will resize it down to 80 in the signature)
• Test the scan with your own phone before adding it to your signature

If your role or contact info changes often, use a dynamic vCard so you can update the underlying record without changing every signed signature in your sent mail.

Add it to Gmail

• Click the gear icon in Gmail and pick "See all settings"
• Scroll to the Signature section and click "Create new" if you have not got one
• Click the image icon in the signature editor and upload the PNG
• Click the inserted image, then "Small" or "Medium" until it sits at about 80 pixels
• Type "Scan to save my contact" underneath in plain text
• Scroll to the bottom and click Save Changes

The image is hosted by Google and travels with every email. No external URL means no broken-image surprises.

Add it to Outlook

• Open File > Options > Mail > Signatures in classic Outlook (or Settings > Mail > Compose and reply in new Outlook)
• Pick the signature you want to edit, or create a new one
• Click the image icon in the editor toolbar and select your PNG
• Right-click the image and pick Size, then set width and height to 80 pixels
• Add "Scan to save my contact" on the line below the image
• Save and assign the signature to new emails and replies

Outlook embeds the image inline, so the signature renders properly even when recipients have external images blocked.

Add it to Apple Mail

• Open Mail > Settings > Signatures
• Pick the account you want and click + to make a new signature
• Drag your PNG into the signature editor
• Right-click the image and pick "View Image at..." to set the size to 80 pixels (Apple Mail has limited image controls; you may need to resize the source PNG to 80px before importing)
• Type "Scan to save my contact" beneath the image
• Close the settings panel; changes save automatically

Common pitfalls

The signature broke the first email I tested. Welcome to the club. Three pitfalls catch most people:

External image hosting. Some signature tools paste a hosted image URL instead of embedding the PNG. If the recipient's mail client blocks external images, the QR shows as a broken square. Always paste the PNG directly into the editor.

Too small to scan. If the code is below 60 pixels, phone cameras struggle to read it on a screen. 80 pixels is the sweet spot for most signatures.

Outdated info. Static vCards bake the data into the QR pattern. Change your phone number and every email you have ever sent points to the old number forever. Use a dynamic vCard if you expect to move jobs, change phones, or rebrand. Read more in can you edit a QR code after printing — the same logic applies to email signatures.

For background, the vCard 4.0 spec covers what fields phones will recognize, and the Wikipedia entry on email signatures covers signature conventions.
