How to Add a Countdown Timer to Kit Email Campaigns Using Countdown Builder

A countdown timer can be useful in a Kit campaign with a real deadline — a course launch, a flash sale, or a limited-time offer.

Kit's email editor includes a custom HTML block, so you can embed a timer generated by an external timer service in broadcasts, sequences, and automations. This tutorial shows how to create a timer in Countdown Builder, add it to a Kit email, and test it before sending.

When a Countdown Timer Helps in Kit

Kit campaigns often promote time-sensitive offers — enrollment windows, launch discounts, live events. A countdown timer gives those deadlines a visual representation:

• Fixed-date timers suit launches and sales with one shared end time.
• Evergreen timers reset per subscriber, which fits Kit's automated sequences where each subscriber joins at a different time.

Step 1: Create Your Countdown Timer with Countdown Builder

1. Visit Countdown Builder: Go to https://app.countdownbuilder.com and sign up for a free account or log in.
2. Set Timer Details:
   • Enter the end date, time, and time zone for your audience.
   • Enable evergreen timer functionality (if needed) to reset the timer based on each subscriber's open time, for Kit's automated sequences.
3. Customize the Design:
   • Select from 45+ templates or build from scratch.
   • Adjust foreground and background colors, choose from an extensive font library, or add a pulsing separator animation.
   • Use advanced label styling to tailor labels (Days, Hours, Minutes, Seconds) for readability and brand match.
4. Configure Custom Expiry Settings:
   • Decide what shows post-expiry:
     • Zero (Default): Display a text message (e.g., "Offer Ended!") as the final GIF frame.
     • Custom Text: Show a branded message.
     • Custom Image: Upload a graphic (e.g., "Sold Out").
   • Useful in Kit automation sequences, where subscribers may open the email after the deadline.
5. Preview and Save:
   • Preview to align with your Kit email's aesthetic.
   • Click Update to save.
6. Copy the HTML Code:
   • Click Copy HTML to get the embeddable code.

Step 2: Add the Timer to Your Kit Email or Automation

1. Log in to Kit: Access your Kit account and navigate to Broadcasts, Sequences, or Automations to create or edit an email.
2. Open the Email Editor: Use Kit's drag-and-drop interface to open your newsletter or automation template.
3. Add a Custom HTML Block:
   • Add the HTML block from the elements menu to your desired spot (e.g., near the CTA or in the hero section).

Step 3: Paste the Countdown Timer Code

1. Edit the HTML Block:
   • Click the block to open the code editor.
   • Paste the HTML code from Countdown Builder into the content area.
2. Save Changes:
   • Click Save to embed the Kit countdown timer. It renders as an animated GIF.

Step 4: Preview and Test Your Countdown Timer

1. Preview the Email: Use Kit's preview tool to check how the timer fits your design and segments.
2. Send a Test Email: Test across devices (mobile, desktop) and clients (Gmail, Outlook, Apple Mail). Older Outlook versions may show only the first frame of an animated GIF.
3. Verify Functionality: Confirm the timer counts down accurately and switches to your custom expiry setting.

Step 5: Launch Your Campaign or Automation

Finalize your content, align the timer's end time with your actual deadline (e.g., a 24-hour launch), and send via broadcast or activate your automation. Kit's analytics will track opens, clicks, and conversions.

Best Practices for Using Countdown Timers in Kit

• Brand consistency: Match colors and fonts to your Kit templates.
• Duration: Set 24–72 hour durations for broadcasts, or use evergreen timers for automated sequences.
• Targeting: Pair timers with Kit's tags, segments, and A/B testing where relevant.
• Mobile: Test how the timer sizes on mobile screens.
• Post-expiry: Use custom expiry settings to show late openers a sensible end state.
• Honest deadlines: Only promote deadlines that are real; offers that still work after the timer expires train subscribers to ignore timers.
