Add a countdown timer to Brevo emails

Live countdowns in your Brevo campaigns and automations — one image URL, no JavaScript, no plugins.

Brevo (formerly Sendinblue) 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 Brevo content block. Every time a contact opens your email, the image re-renders to show the exact time remaining — creating real urgency for sales, launches, and offer deadlines.

How to add a countdown timer to Brevo

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 Brevo email editor, add an image block (or an HTML 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 contact

Running a per-customer offer or an automation? The embed includes a ?end= value that overrides the campaign's default deadline. Swap it for a Brevo contact attribute holding each contact's end time, and everyone sees their own countdown:

The ?end= value accepts a Unix timestamp or ISO 8601 date, so it works with whatever your Brevo attribute stores.

Will it render in my contacts' inboxes?

Yes — it's a plain image, so it displays in Gmail, Apple Mail, Outlook, Yahoo and essentially every client. See the full email client support details, including how animated timers behave in Outlook.

Frequently asked questions

Does Brevo have a countdown timer?

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

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

Create a campaign in UrgencyKit, copy the image embed, then add an image or HTML block in the Brevo editor pointing at the UrgencyKit image URL. It works in both campaigns and automations.

Can each contact see their own deadline?

Yes. Replace the ?end= value with a Brevo contact attribute containing each contact's deadline, and every recipient gets a personalized countdown.
