Kit has its own countdown timer. Why use Alterable?

Use Kit's for a broadcast counting down to one fixed date and time. Reach for Alterable when the deadline should start from each subscriber's own signup, when it arrives from a merge field, or when you want the same timer working outside Kit too. They coexist fine in one account.

Do Alterable countdown timers update in real time?

Yes. The timer is redrawn every time the email is opened, so someone who opens it on Thursday sees the time left on Thursday, not the time left when you hit send.

Does this work in sequences as well as broadcasts?

Yes. The timer is an image URL, so it works anywhere Kit lets you add an HTML block, including sequence emails. Evergreen timers are especially suited to sequences, where every subscriber arrives on a different day.

What happens when the timer expires?

It stops at zero and stays there rather than counting into negative numbers, so an offer that has closed never advertises itself as still running.

Kit (ConvertKit) Countdown Timer: Add One in Minutes

Adding a countdown timer to your Kit emails, formerly ConvertKit, is a reliable way to create urgency and lift conversions. Whether you are running a launch, a cart-close sequence, a webinar reminder or a last-chance offer, a clock that is still ticking when the email is opened pushes subscribers to act rather than to file it away.

In this guide we will walk through building a Kit countdown timer with Alterable and embedding the countdown timer in your broadcast, and we will be straight about when you do not need one.

First, a note on Kit’s built-in countdown timer

Kit ships a countdown timer of its own. It is available from the content block menu in broadcasts, sequence emails, forms and landing pages, and you set an end date and time, pick a style from a dropdown and choose the background and foreground colors.

For a broadcast counting down to a single shared deadline, that is all you need, and adding a second tool for it would be pointless.

Where Alterable earns its place is the cases the built-in timer does not cover:

Evergreen deadlines. A timer that starts from each subscriber’s own signup, rather than one date shared by everyone. In a launch sequence, where subscribers enter on different days, this is usually what you actually want.
Deadlines passed in per subscriber. Take the expiry from a merge field, so a cart hold or a personal offer window can differ for every reader.
One timer across more than one tool. The image URL is just a URL. The same countdown works in Kit, in a transactional email from elsewhere, and on a sales page.
The rest of the platform. Dynamic images, dynamic products, local maps, surveys and scratchers use the same image tag approach, and every one is on every plan.

Why Use a Countdown Timer in Kit?

Encourages Immediate Action – A visible countdown prompts subscribers to act before time runs out.
Increases Click-Through Rates – Urgent emails generate higher engagement.
Boosts Sales and Conversions – Limited-time offers drive faster purchasing decisions.
Strengthens Sequences – Works well in launches, cart-close series and onboarding.
Creates a Personalized Experience – Evergreen countdowns give every subscriber their own window.

Step 1: Generate a Countdown Timer in Alterable

1. Log in to Alterable and navigate to the countdown timer tool.

2. Set your expiration date and time, or choose an evergreen timer if the deadline should run from each subscriber’s own start point.

3. Customize the appearance by selecting the font, colors, and styles that match your brand.

4. Click “Create” to create your live countdown timer.

5. Copy the provided HTML code: this is what goes into your Kit email.

Step 2: Add the Countdown Timer to Your Kit Email

1. In Kit, open the broadcast or sequence email you want to edit.

2. Click the + button where the timer should sit to add a new element.

3. Under Advanced, choose the HTML block.

4. Paste the Alterable code into the block’s text area.

5. Adjust placement so the countdown sits near your call to action, where it does the most work.

6. Send yourself a test and open it to confirm the countdown renders and shows the correct time remaining.

Best Practices for Countdown Timers in Kit

Use for Genuinely Time-Sensitive Offers – A countdown on a deadline that does not exist trains people to ignore your countdowns.
Match the Timer to the Send – Fixed dates for broadcasts, evergreen for sequences where everyone arrives on a different day.
Say What Is Ending – Pair the clock with a line like “Cart closes soon” so the numbers mean something.
Check It on Mobile – Confirm the timer scales properly in the Kit preview and in a real inbox.
Plan for Zero – Decide what the email should say after the deadline passes, because it stays in the inbox long after.

In short

Kit covers the simple case with its own countdown block, and there is no reason to replace it for a straightforward broadcast. Alterable is what you add when the deadline is personal to each subscriber, arrives from a merge field, or needs to work outside Kit too, and it brings the rest of the open-time content along with it.
