How to Add a Countdown Timer to Klaviyo Emails (2026 Guide)

Adding a countdown timer to your Klaviyo emails is one of the fastest ways to increase click-through rates and drive conversions. The good news? You can do it in under two minutes, completely free, and without installing any plugins or apps.

In this guide, we will walk you through the entire process step by step so you can start using animated countdown timers in your Klaviyo campaigns and flows today.

Why Use a Countdown Timer in Klaviyo?

Countdown timers create a visual sense of urgency that static text simply cannot match. When a subscriber opens your email and sees time literally ticking away, the psychological impulse to act is immediate and powerful.

• Higher click-through rates: Emails with countdown timers see an average 30% increase in CTR compared to those without.
• More conversions: Urgency-driven emails convert significantly better, especially for flash sales and limited-time offers.
• Works in flows and campaigns: You can use timers in both one-off campaigns and automated flows like welcome series or cart abandonment.

What You Need

All you need is two things:

1. A free countdown timer from ContadorParaEmail.com
2. A Klaviyo account (free or paid plan)

No apps, no integrations, no technical knowledge required. The timer is generated as an animated GIF image hosted on our servers, so it works everywhere email images are supported.

Step 1: Generate Your Countdown Timer

Go to ContadorParaEmail.com/en/ and configure your timer:

• End date and time: Set when your offer or event expires.
• Colors: Match the timer to your brand colors for a seamless look.
• Language: Choose English labels (Days, Hours, Minutes, Seconds).
• Size: Select a width that works for your email layout (600px recommended).

Once configured, click Generate Timer. You will get an HTML snippet that includes an <img> tag pointing to your personalized animated GIF.

Step 2: Copy the HTML Code

Click the Copy HTML button to copy the complete code snippet to your clipboard. The snippet looks something like this:

<img src="https://contadorparaemail.com/timer/..." alt="Countdown Timer" style="max-width:100%;" />

This single image tag is everything you need. No JavaScript, no external libraries.

Step 3: Paste into Klaviyo

Now open your Klaviyo campaign or flow email and follow these steps:

1. Open the email editor and drag a Text Block or HTML Block into your template where you want the timer to appear.
2. Click the Source Code button (the </> icon) to switch to HTML view.
3. Paste the HTML snippet you copied from ContadorParaEmail.
4. Click Save and preview your email.

The countdown timer will appear as an animated image that counts down in real time every time the subscriber opens the email.

Using Countdown Timers in Klaviyo Flows

Countdown timers are especially powerful in automated flows. Here are the best use cases:

• Welcome series: Offer a limited-time discount to new subscribers with a timer showing when it expires.
• Abandoned cart: Add urgency by showing how long the items will be held or when a discount expires.
• Post-purchase: Encourage a repeat purchase with a time-limited cross-sell offer.
• Win-back flows: Create urgency around a «come back» offer with a visual deadline.

For flows, set the timer end date relative to when the flow triggers. For example, if your abandoned cart flow sends 24 hours after abandonment, set the timer to expire 48 hours from now to give subscribers time to act.

Email Client Compatibility

Because the countdown timer is a standard GIF image, it works across virtually all email clients:

• Full animation: Gmail, Apple Mail, Yahoo Mail, Outlook.com, Samsung Mail, and most mobile clients.
• Static fallback: Older versions of Outlook for Windows display the first frame of the GIF, which still shows the countdown numbers.

Tips for Best Results

• Place the timer above the fold so subscribers see it immediately when they open the email.
• Match your brand colors for a professional, cohesive look.
• Pair with a clear CTA button directly below the timer.
• Use honest deadlines: Never fake urgency. Set real deadlines and honor them.
• Test on mobile: Always preview how the timer looks on mobile devices.
