Central email signatures

Central signature tools (CodeTwo Email Signatures for Office 365, Exclaimer, or
Microsoft 365's own server-side signatures) apply one template to everyone's mail.
Kard plugs into them so each person automatically gets their own QR code and card
link — no per-user setup.

You'll find a ready-made template, a live preview and a copy button on the Team page
under Email signatures.

How it works

A central template can't hard-code kard.be/{slug} because the tool doesn't know each
person's slug — it only knows their email address. So Kard exposes two public URLs
that take an email and resolve it to that user's card at send time:

• https://kard.be/signature/qr?email={Email} — returns that person's QR code as a PNG.
• https://kard.be/signature/card?email={Email} — redirects to that person's card.

Your signature tool replaces the {Email} placeholder with each recipient's address, so
one template produces a personalised QR and link for every member.

The template

Paste this into your signature tool's HTML editor and keep the {Email} placeholder:

<a href="https://kard.be/signature/card?email={Email}">
  <img src="https://kard.be/signature/qr?email={Email}&size=200"
       width="120" height="120" alt="My digital business card"
       style="display:block;border:0;">
</a>

In CodeTwo, {Email} is the user's email placeholder — use the placeholder picker if
your tool writes it differently (for example {User.Email} or {%Email%} in Exclaimer).
The two URLs are the same whichever tool you use; only the placeholder syntax changes.

What appears for whom

• Only published cards appear — the member must have a public card on an active plan.
• Private cards, lapsed trials and people without a Kard account return an invisible
  blank for the QR and send the link to the Kard home page. Signatures never show a
  broken image or point at an offline card.
• The email in the placeholder must match the member's Kard account email (their
  Microsoft sign-in address). Aliases that differ from the sign-in address won't resolve.

Test before you roll it out

1. Send yourself a message with the new signature applied.
2. Confirm the QR resolves to your card and the link opens it.
3. Scan the QR with a phone to check it points at the right person.

Because the QR and link resolve live, you never need to regenerate the template when
members edit their cards or change their slug — the same template keeps working.
