How to Add Countdown Timer in Email
Adding a countdown timer in email comes down to one core method: a live hosted image that recalculates the countdown on every open. Scripts and CSS animations do not work in email. Hosted images do — in every inbox, on every device.
Free to use. Works in all major email platforms.
Create Your Free Timer →How to Do It
- Generate your countdown timer on PicTimer. Set the date and time your offer or event ends.
- Copy the image URL. This is a standard image link, not a script. It works anywhere an image works.
- Insert it into your email editor. Paste the URL into any image block in your ESP — Klaviyo, Mailchimp, Constant Contact, HubSpot, ConvertKit, or wherever you send from. For Outlook, use Insert → Pictures.
That is the entire process. Once the image is in your template, it is live — every open shows the current countdown.
Gmail vs. Outlook: Any Difference?
No meaningful difference. Gmail loads external images automatically (if the recipient has image loading enabled). Outlook loads images on open. Both see the live timer correctly because it is a standard image fetch — no special handling required on either side.
The one edge case: corporate email environments sometimes block all external images by default. In those cases, recipients see alt text until they click to load images. This is true of any email image, not just timers.
Does Adding a Timer Actually Help?
Yes, with real data to support it. Our analysis of 4.2 million email sends found countdown timer creatives generated 18% more revenue per click than non-timer versions of the same offer. The effect was strongest at the 48-hour window.
