It removes the mental maths
Nobody works out what "ends 11:59pm Pacific" means in their own timezone. The timer has already done it, in their local time, in the size of the number.
An email countdown timer that keeps counting after you hit send
A countdown timer you can put inside an email. It shows the real time left every time someone opens your campaign, so “closes soon” stops being a phrase people skim and becomes a number they can see running out — which is what turns a read into a click.

Why it works
How a countdown timer in email lifts conversions
A campaign competes with everything else in the inbox. A deadline written as text is something a reader has to decode and remember; a deadline they can watch moving is something they act on while the email is still open. That is the whole mechanism — it moves the decision from later to now.
It stays true on the second open
Most clicks do not happen on the first read. Because the image is redrawn on open, someone returning the next morning sees a shorter countdown, not a stale one — and a shorter one is more persuasive.
It gives the CTA a reason
A button on its own asks for a decision with no cost to delay. The same button under a running clock has a reason to be pressed now, which is what separates a good open rate from a good click rate.
Urgency only works when it is real. A countdown on a deadline you will not actually honour trains subscribers to ignore the next one, so point it at something true — a price that changes, a cart that closes, a session that starts.
Designs
Countdown timer designs, one embed code
Pick the shape that suits the send. Every design renders to an animated GIF that any email client can show, and switching between them changes the picture, never the code you pasted — so you can change your mind after the campaign has gone out.

Every style, any colour
Each design pairs with the full theme palette, so the digits and the box take your brand colour. Contrast is checked on render, so digits stay readable on light and dark templates alike.
Worked examples
What an email countdown timer looks like in a real campaign
The timer is an image, so it sits wherever an image can: above the fold, beside the offer, or right on top of the button. These are the four sends it earns its place in most often.

Bring urgency to a seasonal sale
Design: Split
Black Friday, Cyber Monday, end-of-season — a deadline the reader can see beats a deadline they have to read about. The image re-renders on every open, so it is always right.
Consistent deadline
One countdown for email, website and a shareable page
Campaigns get confusing when the email says one thing, the landing page says another, and the website banner keeps running after the offer is over. CountdownShare is built around one timer that can appear in multiple places: email output, a matching countdown page, and a website countdown timer embed.
That matters for subscribers who open late or click twice. The email timer can link to the same destination as your CTA, while the shareable page gives you a fallback when an email platform strips formatting or when you want a simple campaign URL for social, sales, or support.
Setup workflow
How to add a countdown timer to an email
Normal website countdown code is not reliable in email. Most inboxes block JavaScript and iframes, so the email version needs to be an image-based timer or an animated GIF that an email client can render like a normal image.
1
Choose deadline and timezone
Set the exact campaign end date, time, and timezone before you design the email. This keeps your subject line, body copy, landing page, and timer aligned.
2
Customize the timer
Choose the campaign title, preset, colors, labels, and destination URL. The preview updates immediately, so you can check the design before creating the timer.
3
Generate the email-safe timer
CountdownShare creates an image-based email asset. Free output is a static watermarked image. Pro can generate animated email countdown GIF output.
4
Copy HTML or image URL
Use the full linked HTML when your editor supports custom code. Use the direct image URL when your editor works better with an image block.
5
Paste it into the email platform
Add the snippet near the campaign CTA in Mailchimp, Klaviyo, Brevo, HubSpot, ActiveCampaign, ConvertKit, SendGrid, Gmail, Outlook, or another email tool that supports images or HTML.
6
Send a test email
Open the test in the inboxes your audience uses. Check Gmail, Outlook, Apple Mail, mobile width, image-blocked behavior, and the click destination before the real send.
Need the lower-level HTML details? Use the HTML email countdown timer guide after creating your timer. Still deciding which tool to standardise on? The free email countdown timer comparison covers what to check before you commit a campaign to one.
Works with every major email platform
The email embed is an ordinary <img> tag pointing at a hosted, animated GIF. Any platform that lets you paste HTML, or set a custom image source, can send it — which is effectively all of them.
That also means nothing runs on their side. There is no integration to authorise and no account to connect, so a countdown works the same in a one-off broadcast as it does inside an automation.
- No plugin, no app install, and nothing to add to your sending domain.
- The timer is a plain image tag, so it survives the editor rewriting your HTML.
- Change the design or the deadline after the send — the image re-renders on open.
- Send yourself a real test first: clients differ in how they cache images.
Step-by-step setup guides
Mailchimp
Paste the generated HTML into a Code block, or use the image URL in an image block with a link.
Klaviyo
Use a campaign or flow template block that accepts HTML, then preview the desktop and mobile email.
Brevo
Add the timer through an HTML block in the drag-and-drop editor and verify the final inbox render.
HubSpot
Use a custom HTML module or an image module pointed at the generated countdown image URL.
ActiveCampaign
Place the email-safe HTML inside automation emails or one-off campaigns near the deadline CTA.
ConvertKit
Use the timer in launches, creator broadcasts, and sequences where a real deadline changes the offer.
SendGrid
Add the image HTML to a dynamic template where the timer and destination link belong in the message.
Plan fit
Free versus Pro email timer
Free is useful when you need a simple email-safe static image and a matching page. Pro is for campaigns where the timer needs to tick inside the email, stay on brand, and be measured after launch.
Free
Create up to 3 active free timers. Email output uses a watermarked static countdown image and linked HTML. You can preview the design and copy output before you send.
- Static email image with CountdownShare branding
- Copy-ready HTML and direct image URL
- Matching countdown page for the same deadline
Pro
Pro adds the campaign controls most marketers need for revenue emails: animated email countdown GIF output, watermark removal, analytics, editable settings, evergreen timers, branding and custom CSS, and higher or unlimited usage according to the active Pro limits.
- Animated email countdown GIF
- Watermark removal and cleaner campaign assets
- Analytics for campaign performance
- Branding, custom CSS, editable settings, and evergreen timers
Campaign ideas
Email countdown use cases
Launch sequence
Use one fixed deadline in announcement, reminder, and final-call emails so every subscriber sees the same launch close time.
Flash sale
Put the timer close to the discount explanation and link it to a page that switches to standard pricing after the sale ends.
Webinar reminders
Count down to registration close, session start, or replay expiry. Include the timezone in plain text near the timer.
Abandoned cart offer
Use a personal window only when the discount or bonus really expires for that shopper.
Trial conversion
Remind users when introductory pricing, bonus credits, or account access changes at the end of a trial.
Newsletter event push
Give subscribers a visual reminder for ticket close, application deadlines, store drops, or limited booking windows.
Automated personal windows need extra care. Start with the evergreen countdown timer guide when every subscriber receives a different deadline.
Pre-send checklist
Best practices
A timer improves a campaign only when the rest of the message is clear. Treat it as a deadline display, not a substitute for offer copy, landing page consistency, or honest post-expiry behavior.
- Name the consequence: say what changes when the timer reaches zero.
- Keep one deadline across the email, website timer, checkout, and shareable countdown page.
- Do not rely on the image alone. Add a plain-text deadline for blocked images.
- Use a destination URL that still makes sense for late openers after the deadline.
- Test dark mode, mobile width, Outlook, Gmail, Apple Mail, and your own ESP preview.
- Use evergreen timing only when each subscriber truly has a personal window.
- Track clicks and conversions, not only opens. The timer should help the campaign outcome.
For developers
Generating email countdown timers with an API
Everything above is a timer you create once and paste into a campaign. When the timers have to be created by your own system — one per order, per abandoned cart, or per subscriber — the Countdown Timer API returns a ready-to-paste email-safe animated image for every timer it creates, rendered at the moment the recipient opens the message.
For a deadline that differs per recipient — a 48-hour window starting when each person was emailed rather than when you pressed send — personalized timers fix a separate expiry per subscriber, computed on the server so the email, your app, and your billing all agree.
FAQ
Frequently asked questions
Can I put a normal JavaScript countdown timer inside an email?+-
No. Email clients generally do not run normal website JavaScript or iframe countdowns. CountdownShare email output uses an image-based method, with animated GIF output available on Pro.
Is the free email countdown timer animated?+-
No. Free email output is a static watermarked image that can be pasted into an email and linked to the matching countdown page. Animated email countdown GIF output requires Pro.
What can I copy after generating a timer?+-
You can copy linked email HTML or a direct countdown image URL. Use the HTML when your editor supports custom code, and use the image URL when your editor uses image blocks.
Does the timer work in Gmail and Outlook?+-
Image-based timers can display in Gmail and Outlook when remote images are loaded. Some Outlook versions may show only the first frame of an animated GIF, so always include text fallback copy and send a real test.
Can one countdown work in email and on my website?+-
Yes. A CountdownShare timer can support email output, a shareable countdown page, and a website embed. That is useful when a campaign sends subscribers from inbox to page.
Can I edit a timer after sending the email?+-
Pro supports editable settings. For any email campaign, send another test after edits and make sure the destination page still matches the promise in the already-sent email.
When should I use an evergreen email timer?+-
Use evergreen timing for real subscriber-specific windows, such as a trial ending, a personal bonus window, or an automation-triggered offer. Do not use it to make a public deadline look personal.
