Countdown Timers in Mailjet
Mailjet is a powerful email marketing platform popular in Europe and Latin America. Its Passport editor allows you to insert custom HTML blocks where you can easily paste your countdown timer code. No plugins or third-party integrations required.
Adding a countdown timer to your Mailjet campaigns creates a sense of urgency and scarcity that motivates subscribers to take action before time runs out.
Step 1: Generate Your Countdown
Visit the ContadorParaEmail generator, configure your timer (deadline, colors, font, language), and click the "Klaviyo / Mailjet" tab to copy the optimized code.
The generator supports 9 languages and over 30 fonts, so you can create timers that match any audience or brand.
Step 2: Insert in Mailjet (Passport Editor)
- Open your campaign in Mailjet and enter the Passport editor
- Drag an "HTML" block to the desired position
- Paste the code copied from the generator
- Save and preview — the countdown will appear animated
What If I Use MJML?
If you work with MJML (Mailjet's email framework), you can insert the countdown inside an <mj-raw> block or directly as an image in an <mj-image> component using the direct URL of the timer. Copy the URL from the "Direct URL" tab in the generator.
Mailjet + Transactional Emails
Countdowns also work in Mailjet transactional emails. This is useful for order confirmation emails with shipping countdown timers, event reminders, or limited-time discount notifications sent via the Mailjet API.
