Add a countdown timer to Mailchimp emails

A live countdown in your Mailchimp campaigns — one image URL, no JavaScript, no plugins.

Mailchimp doesn't ship a built-in live countdown timer for emails. UrgencyKit adds one the simplest way possible: a single image URL you drop into any Mailchimp content block. Every time a subscriber opens your campaign, the image re-renders to show the exact time remaining — creating real urgency for sales, launches, and cart deadlines.

How to add a countdown timer to Mailchimp

1. Create a campaign in UrgencyKit and set your deadline and timezone.
2. Style it — choose a background, fonts, and colors to match your brand.
3. Copy the embed from the editor.
4. In the Mailchimp campaign editor, add an Image block (or a Code block for full control) and use the UrgencyKit image URL.
5. Send a test to yourself and confirm the countdown shows the right time.

Personalize the deadline per subscriber

Running an evergreen funnel or per-customer offer? The embed includes a ?end= value that overrides the campaign's default deadline. Swap it for a Mailchimp merge tag holding each subscriber's end time, and everyone sees their own countdown:

The ?end= value accepts a Unix timestamp or ISO 8601 date, so a text merge field like *|DEADLINE|* just needs to hold either format — set it via your audience import, an automation, or the Mailchimp API.

Will it render in my subscribers' inboxes?

Mailchimp lists span every kind of inbox — Gmail, Apple Mail, Outlook, Yahoo, corporate domains — and the countdown renders in all of them, because a plain image is the one element every email client displays.

Frequently asked questions

Does Mailchimp have a countdown timer?

Not a built-in live one for emails. UrgencyKit adds it as a single image URL you paste into any Mailchimp content block, and the image renders the current countdown on every open.

How do I add a countdown timer to a Mailchimp email?

Create a campaign in UrgencyKit, copy the image embed, then add an Image or Code block in the Mailchimp editor pointing at the UrgencyKit image URL.

Can each subscriber see their own deadline?

Yes. Replace the ?end= value with a Mailchimp merge tag containing each subscriber's deadline, and every recipient gets a personalized countdown.
