Email signature generator linked to your digital business card

An email signature generator turns your contact details into a formatted signature that you paste into your email app once. CardDeck's version is built from your digital business card, so the signature, the card and the QR code always show the same information.

What CardDeck generates

• Your photo or company logo
• Your name, job title and company
• One or two key contact lines, such as phone and website
• A link to your full digital business card, labeled clearly, for example "Save my contact"
• Optionally, a small QR code image for people reading on a desktop who want your card on their phone

Why link to a card instead of listing everything

A signature that tries to hold every number, address and social icon gets long, breaks on mobile and is out of date the moment something changes. A short signature with one link to your card stays tidy. When your title or phone number changes, you update the card and the link in every email you have ever sent opens the new details.

Who it is for

• Professionals who want recipients to save their contact properly
• Small teams that want consistent signatures without a design tool
• Anyone who has changed job titles and left old signatures in hundreds of threads

A professional email signature should include your name, job title, company, one or two ways to reach you and a link to more. Four to six lines is usually enough.

Recommended content

1. Name: as you want people to address you.
2. Job title and company: on one line if they fit.
3. One phone number: in international format, for example +1 415 555 0134.
4. Website or card link: "View my card" or "Save my contact".
5. Small photo or logo: one image, not several.

Optional additions

• Pronouns, if you use them in your workplace.
• A booking link, if meetings are your main call to action.
• An office address, if clients visit you.

Legal and policy lines

In some countries, business emails from registered companies must include details such as the company's registered name, number and office address; the UK and Germany are common examples. Check what applies to your business, and keep any confidentiality notice short.

What to leave out

• Inspirational quotes and long taglines
• More than three social icons
• Animated images
• A second email address that is already in the From line
• Images of text, which may be blocked or unreadable

Copy the signature from CardDeck, then paste it into the signature settings of your email app. Each app keeps the formatting and images when you paste the rendered signature rather than raw code.

Gmail (web)

1. Open Gmail and select the gear icon, then See all settings.
2. On the General tab, scroll to Signature and choose Create new.
3. Name the signature and paste it into the editor.
4. Set it as the default for new emails and for replies and forwards.
5. Scroll down and select Save Changes.

Gmail signatures are limited to 10,000 characters, which a CardDeck signature stays well under.

Outlook (web and new Outlook)

1. Open Settings, then Accounts, then Signatures.
2. Create a new signature, give it a name and paste it in.
3. Choose it as the default for new messages and replies, then save.

Classic Outlook for Windows has signatures under File, Options, Mail. Signatures do not sync between every Outlook version, so check each device you use.

Apple Mail (Mac)

1. Open Mail, then Settings (or Preferences), then Signatures.
2. Select your account, add a new signature and paste it in.
3. Uncheck Always match my default message font so your formatting is kept.

On your phone

Mobile apps often use a separate, plain-text signature. Keep it to your name, title and card link.

Linking your email signature to a digital business card turns every email into a way to save your contact properly, and keeps old emails pointing to current details.

Benefits

• Always current: emails from last year still open your latest card.
• Proper saving: one tap on your card adds a vCard with your photo, title and company to the recipient's phone, instead of them copying text from a signature.
• More than fits in a signature: your card can hold links, a booking button, a portfolio and a WhatsApp button without cluttering your email.
• Two-way contact: recipients who open your card can share their details back, and those contacts arrive tagged with their source in contact management.
• Measurement: CardDeck analytics count views from your signature separately from QR scans and NFC taps, so you can see how often email leads people to your card.

A useful pattern

Use a short line in your signature such as "Save my contact" or "View my card" rather than a raw URL. People understand what will happen, and the line looks tidy on desktop and mobile.

For sales and client-facing roles

Signatures are one of the steadiest sources of card views because every email carries them. Reps who send dozens of emails a day get their details saved by people they may never meet in person.

The simplest way to keep team email signatures consistent is to generate them from cards that share one locked template. Every signature then uses the same layout, colors and logo, and only personal fields differ.

How it works with CardDeck

1. An admin sets up a team workspace with the company brand kit and a locked card template.
2. Members fill in their own name, title, photo and phone; the design cannot drift.
3. Each member generates their signature from their card and pastes it into their email app.
4. When company details change, such as a new logo or address, the admin updates the template and the cards update for everyone. Signatures that link to cards stay current.

Onboarding and offboarding

• New hires get a card on day one, imported in bulk if needed, and a signature that matches.
• When someone leaves, their card can be deactivated or redirected to a colleague, so links in old email threads still reach the company.

Brand checks

Before rolling out, send a test email from each email app your team uses, open it on desktop and mobile, and in both light and dark mode. Fix any image or color issue in the template once rather than person by person.

Signatures break when they rely on images, get too wide or use unusual fonts. Keep the layout narrow, mostly text and tested in dark mode.

Size and layout

• Keep the whole signature narrower than about 600 pixels so it fits mobile screens without scrolling sideways.
• Display a photo or logo at roughly 80 to 100 pixels wide, uploaded at double that size so it stays sharp on high-resolution screens.
• Use one column of text beside or below one image.

Text and fonts

• Use web-safe fonts such as Arial, Helvetica, Georgia or the recipient's default. Custom fonts usually fall back anyway.
• Keep body text around 12 to 14 px and your name slightly larger or bold.
• Use real text, not images of text, so details remain readable when images are blocked.

Images

• Many email clients block images until the recipient allows them, so the signature must make sense without them.
• Host images rather than attaching them; attached images can show up as files in every email.
• Avoid animated GIFs and large banners.

Dark mode

Some apps invert colors in dark mode. Use a logo with a transparent or light background that still reads on dark, and avoid pure black text on images.

Test before you roll out

Send yourself a test from each app and open it in Gmail, Outlook and on a phone. Check that links work and the card opens correctly.
