How to add a countdown timer to Mailjet
Mailjet’s templating language substitutes contact properties anywhere in the message, URLs included — so a countdown needs no integration, only one image tag. The same approach covers marketing campaigns and transactional sends.
-
Design your countdown in tikio
Create a timer in the tikio editor: pick colors, fonts, labels and the languages you need. What you see in the editor is exactly what lands in the inbox — the timer is delivered as a regular animated image.
-
Publish and copy the image URL
Hit Publish and copy the public image URL. The deadline lives in the URL as a parameter, so the same link works for every campaign — change the date, not the link.

Insert the timer into your Mailjet email
In the Mailjet editor, add an HTML section and paste the snippet below. Mailjet resolves [[data:…]] contact properties inside the URL for each recipient at send time.

Per-recipient evergreen deadlines
Point the recipient key at whichever contact property holds a stable identifier — an internal user ID is ideal. Mailjet lets you supply a default value, so the key never renders empty.

Does this work in transactional emails?
Yes. The timer is a plain image URL, so it renders the same whether the send is a campaign or a transactional message triggered by your app.
What if the contact property is missing?
Give it a default value in the templating tag. With an empty key the countdown falls back to shared behaviour rather than a personal deadline.
Can I send the same countdown to French and English lists?
Yes — bake both locales into the design once and set lang=fr or lang=en in the URL per campaign.
