To add a digital business card to your email signature, copy your card’s share link and paste it into your email app’s signature settings as a clickable text link, such as “Save my contact”. In Gmail that’s Settings > See all settings > Signature, and in new Outlook it’s Settings > Accounts > Signatures. A small QR code image is optional, and it should never replace the text link.
What you need before you start
You need a digital business card with a share link that stays the same when you edit the card. That link is what goes into the signature. If you don’t have a card yet, see how to create a digital business card for free.
Have these ready:
- Your card’s share link, for example
https://qrcard.in/c/priya - A short label for the link (“Save my contact” works better than the raw address)
- Optionally, a QR code image of the same link, exported as a small PNG
Text link, image or QR code: which works in a digital business card email signature?
A plain text link is the only format that works for every reader of a digital business card email signature. Images and QR codes fail in common situations, so treat them as extras.
Microsoft’s support page on picture downloads in Outlook says “Microsoft Outlook is configured by default to block automatic picture downloads from the Internet.” The reason is privacy: blocking helps readers avoid tracking pixels. So a clickable banner or QR image may arrive as an empty box.
A QR code has a second problem. Someone reading your email on their phone can’t scan a code shown on that same screen. They need something to tap.
| Format | Shows when images are blocked | Works on a phone | Best use |
|---|---|---|---|
| Text link (“Save my contact”) | Yes | Yes, tap it | Always include |
| Clickable image or banner | No | Yes, if loaded | Optional, branded look |
| QR code image | No | No, same screen | Desktop readers who want the contact on their phone |
My take: one line of text with your name, title and a “Save my contact” link beats any banner. It loads everywhere and it’s harder to mistake for an ad.
How to add the card link in Gmail
In Gmail on a computer, the signature lives under Settings > See all settings, in the Signature section. These steps follow Google’s Gmail signature help.
- Open Gmail, click Settings at the top right, then See all settings.
- Scroll to the Signature section and create or pick a signature.
- Type your name and title, then type “Save my contact”.
- Select that text, click the link icon in the toolbar and paste your card link.
- At the bottom of the page, click Save Changes.
Gmail allows up to 10,000 characters in a signature, and Google notes that “your image also counts toward the character limit.” If you add a QR image and get an error, make the image smaller.
How to add the card link in Outlook
In new Outlook and Outlook on the web, go to Settings > Accounts > Signatures. Microsoft’s signature guide says the steps are the same for both versions.
- Select Settings, then Accounts > Signatures.
- Create a new signature and type your name, title and “Save my contact”.
- Select the link text and use the mini formatting bar under Edit signature to insert your card link.
- Save, and set it as the default for new messages and replies if you want it everywhere.
In classic Outlook, the path is different: on the Message menu, select Signature > Signatures.
One catch from Microsoft’s page: signatures stored “on this device” may not be available when you use Outlook on another device. If you use Outlook on a laptop and a desktop, check each one.
How to add the card link in Apple Mail on a Mac
In Apple Mail on a Mac, choose Mail > Settings, then click Signatures. The steps come from Apple’s Mail guide.
- Choose Mail > Settings, then click Signatures.
- Click the Add button below the signature list and name the signature.
- Type your name, title and “Save my contact” in the preview area.
- Turn “Save my contact” into a link to your card, or paste the full card link on its own line.
To add a QR image, drag it into the preview area.
How to check the link works
Send a test email to a different account and open it on a phone. That’s the view most of your recipients will have.
- Tap “Save my contact” and confirm your card opens.
- On the card, tap the save button and check the contact lands in the phone’s Contacts app.
- Open the same email in a desktop client with images blocked. The text link should still be there.
Keeping the signature up to date
A digital business card link keeps the signature current because you edit the card, not the signature. If you change jobs or phone numbers, update the card and every email you’ve already sent points to the new details. See how to update a digital business card for what to change first.
How QRCard handles this
QRCard gives each card a share link in the form https://qrcard.in/c/yourname. Edit your details once and all shared links and QR codes show the current info. Recipients don’t need an app: tapping Save Contact downloads a .vcf file that opens in the Contacts app on iOS or Android. The free plan includes the QR code download if you want an image.
The limitation: QRCard can’t fix image blocking in your reader’s email app, and the one-click email share option is on Pro, not Free. On the free plan you copy the link yourself, which is all a signature needs.

FAQ
Should I put a QR code in my email signature?
Only as an extra. Most people read email on the phone they’d scan with, so a QR code can’t help them, and Outlook blocks pictures by default. Put a clickable text link first.
Why doesn’t the image in my email signature show up?
Many email apps block pictures until the reader allows them. Microsoft says Outlook is configured by default to block automatic picture downloads from the Internet.
Do I need to update my signature when my details change?
Not if the signature links to a digital business card. Change the details on the card and the same link shows the new version.
Why does Gmail say my signature is too long?
Gmail allows up to 10,000 characters, and an image counts toward that limit. Google suggests resizing the image if you get an error.
