How to Add a Countdown Timer to Your HubSpot Marketing Email with Countdown Builder

HubSpot's email editor includes an HTML module, so a countdown timer generated by a timer service can be embedded in a marketing email without custom development.

This guide walks through the steps with Countdown Builder, the timer service this blog is published by: create the timer, copy the HTML, add the module, preview, and send.

When to Use a Countdown Timer in HubSpot Emails

A countdown timer suits emails with a real expiration — flash sales, event registration, limited-time offers, product launches. It places the deadline in the email itself, next to the action you want readers to take.

Once the campaign is running, HubSpot's reporting covers the rest: open rates, clicks, and conversions for the email that carries the timer.

    C --> D["Paste the timer HTML"]
    D --> E["Preview, then send"]

Step 1: Create the Timer in Countdown Builder

1. Visit Countdown Builder: Go to Countdown Builder and sign in or create an account.
2. Create a new timer and set the end date and time for your campaign — for example, the end of a sale or event.
3. Customize the design: adjust the font style, size, background color, and text color to match the email's design.
4. Copy the HTML code: click Copy HTML to copy the embed code to your clipboard.

Step 2: Add the Timer to Your HubSpot Email

Open the HubSpot email builder: Log in to your HubSpot account and go to Marketing > Email. Create a new email or edit an existing template.

Add an HTML module: In the email editor, open the Add tab in the left sidebar, click More, and locate the HTML – Email block. Drag the module to where the timer should appear in the layout.

Paste the HTML code: Click the HTML module to open the editor, and paste the code you copied from Countdown Builder into the HTML text box.

Save and preview: Save your changes, then use HubSpot's preview and send a test email to check the timer on desktop and mobile.

The timer is now part of the email. Each open loads a fresh timer image with the current time remaining.

Best Practices for Countdown Timers in HubSpot Emails

• Place near CTAs: position the timer next to the call-to-action button so the deadline and the action sit together.
• Match your branding: timer colors and fonts consistent with the rest of the email.
• Test across devices: use HubSpot's preview and test-send features before the real send.
• Image blocking and Apple Mail: some readers block images, so state the deadline in plain text as well. Apple Mail Privacy Protection can freeze the animation; Countdown Builder serves a static fallback in that case.
• Track results: compare the timer email's opens, clicks, and conversions against a similar email without one, using HubSpot's email reporting.
• A/B test designs: HubSpot's A/B testing can compare placements, colors, or timer vs. no timer.

Final Thoughts

The HubSpot setup is one HTML module and a pasted snippet. What the timer does from there depends on the campaign — it communicates a deadline, and it's worth using when that deadline is real.

If you'd like to try it, you can create a free timer. The free plan doesn't require a credit card and doesn't add a watermark.
