A recreation. The real timer is an image drawn at each open.

From deadline to live countdown in three steps

Set the deadline, style it, paste one image tag into your ESP. Alterable draws the timer fresh every time the email is opened.

Configure your countdown timer

Pick one of the three types below, set the deadline, then match the colours, fonts and labels to your brand.

Copy your embed code

Alterable generates a short snippet: an image tag in a link. No JavaScript, no SDK. Works as a plain image URL in any ESP: Klaviyo, Mailchimp, HubSpot, or anything else that sends HTML email.

Send and watch it tick

The timer is drawn fresh at every open, so each recipient sees the time actually left. Track impressions in the dashboard, with country and device where your ESP or the mail client provides them.

A sample email, in your inbox

A sample email with a Deal of the Day countdown that is live when you open it, sent to your own inbox.

Many mail apps load images through their own servers, which hides where you are and what phone you use. Add your city for the weather-based offer and pick your phone for the matching deal and app badge. Anything left blank gets the standard version.

Three ways to set the deadline

One date for your whole list, a window that starts when each subscriber’s email is sent, or a deadline your ESP passes in for each recipient. Same embed either way.

One hard deadline for your whole list. When it hits zero, the sale is over.

Ten styles, same timer

Pick the ring or the digits, then set the colours to match the email it sits in. Every style renders as an image at open-time, so it looks the same in every client.

One image tag, still ticking in any ESP

A countdown timer is just an image tag. Paste it into Klaviyo, Mailchimp, HubSpot, Brevo, or any ESP that accepts an image tag with merge tags. If it can show an image, it can show your countdown.

No merge tags for a fixed deadline: every reader counts down to the same moment. The IDs are placeholders; Alterable gives you the real tag to copy.

Questions about countdown timers

Do I need a fixed end date?

No. A deadline timer counts down to one moment for your whole list, an evergreen timer (Pro and up) starts when each recipient’s email is sent, and a merge-tag timer takes the expiry straight from your ESP for genuinely per-recipient deadlines.

Which email clients does it work in?

Any client that shows images. Alterable generates a standard image tag with no JavaScript, so it works from Klaviyo, Mailchimp, HubSpot, GetResponse, Omnisend, Brevo, Constant Contact or anything else that sends HTML email. The timer is an animated image: classic Outlook on Windows shows only its first frame, so the time is right at open but does not tick.

What happens when the timer hits zero?

The timer stops at zero rather than counting into negative numbers, so an offer that has closed never advertises itself as still open. If you like, set an expiry message or an image of your own to take its place after the deadline.

How does it handle time zones?

You set the deadline in whichever timezone you choose, and every reader counts down to that same moment. For a deadline that is different per reader, pass it in from your ESP with a merge-tag timer.
