How to Add Countdown Timer to Email

To add a countdown timer to email, you need a dynamic image URL — a hosted image that redraws the countdown on every fetch. This is the only method that works reliably across Gmail, Outlook, Apple Mail, and every mobile inbox.

You can make one for free on PicTimer.

The Process

1. Build your timer. Set the end date and time. PicTimer supports fixed deadlines (one end time for everyone) and evergreen timers (personalized countdowns per recipient).
2. Copy the image link. Your timer URL works in any email editor that accepts images — which is all of them.
3. Paste it into your email builder. Use an Image block and set the PicTimer URL as the source. Link the image to your offer page so the click drives traffic directly.

This Works Across All Major Platforms

• Gmail — Paste in an image block. Gmail loads external images automatically.
• Outlook — Use Insert → Pictures. Full guide: countdown timer in Outlook.
• Klaviyo — Drag an Image block, paste the URL. Full guide: countdown timer in Klaviyo.
• Mailchimp, Constant Contact, HubSpot, ConvertKit, ActiveCampaign — Same process: image block, PicTimer URL as source.

Why Timers Work in Email

It comes down to post-click intent. Seeing a ticking clock makes the abstract deadline concrete. Recipients who click through under that pressure complete purchases at a higher rate than those who click without the visual urgency cue.

In a real campaign across 4.2 million sends, timer creatives delivered 18% more revenue per click. That is a meaningful lift on any campaign with real volume behind it.
