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.

  1. 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.

  2. 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.

  3. 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.

    <img src="https://tikio.io/e/a1b2.gif?target=2026-08-01T20:00" alt="Offer ends soon" width="480" style="max-width:100%;" />

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.

FAQ

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.
