How to Add a Countdown Timer to a Klaviyo Email

Klaviyo fully supports externally hosted images, which is exactly how countdown timers work in email. You do not need a Klaviyo integration, a custom block, or any coding — just an image URL from PicTimer and Klaviyo's standard image block.

Steps: Adding a Countdown Timer to Klaviyo

1. Create your timer on PicTimer. Set the deadline date and time that matches your campaign — a sale end date, offer expiration, or event countdown.
2. Copy the image URL. PicTimer generates a live image URL. This is a real image address, not a script — it works anywhere images are accepted.
3. In Klaviyo's email editor, drag an Image block into your template. You can place it above your headline, below your offer text, or wherever it will have the most visual impact.
4. In the Image block settings, paste your PicTimer URL as the image source. Klaviyo will fetch and display the timer live. Set a link on the image to your offer page.

Fixed vs. Evergreen Timers in Klaviyo

PicTimer supports both timer types, which maps directly to how Klaviyo is typically used:

• Fixed deadline timers — Set a specific end date for sale campaigns, flash promos, or event-based emails. The same timer counts down for every recipient.
• Evergreen timers — Each recipient gets a personal countdown starting from when they open the email. Ideal for welcome flows, abandoned cart sequences, and drip campaigns where every subscriber enters at a different time.

Evergreen timers pair especially well with Klaviyo's flow automation. A recipient who opens your abandoned cart email on day one sees a different remaining time than one who opens it on day three — keeping urgency genuine rather than fake.

Does It Actually Work?

Yes — and there is real data to back it up. Our case study across 4.2 million email sends found that countdown timer emails generated 18% more revenue per click than non-timer creatives on the same offer. The 48-hour window was the strongest performer.
