The problem
They opened it. They liked it. They didn't buy.
You paid for the list, the design and the discount. Then “maybe later” spent it all, because nothing in the email said now.
An inbox: your sale email, opened on Monday and left for later, sinks under newer email every day until the sale ends unbought.
What you've tried
- “Ends Friday!” in the subject lineRead once, at the open. By the time they're ready, it's three emails down.
- Another reminder emailOne more send, a few more unsubscribes, and the same “later”.
- A deeper discountLess margin on every order, and still no reason to buy today.
It's not your offer. Nothing in the email says now.A countdown does, and Flash Render keeps flashtimer's accurate to the second, however late they come back.
In the inbox
See it in a real campaign.
Three emails every store sends, each with a live countdown rendered by flashtimer as you read. Open one, or switch to mobile to see it the way most of your readers will.

Browse every exampleHow it works
Live in your next email, in about a minute.
No code, no plugin, no designer. If your email can show an image, it can show a countdown.
A prompt, “Black Friday sale ending Friday at midnight, our brand colours, urgent tone”, turned into a countdown timer ready to use.
Step 1
Describe your sale. AI designs it.
Tell it the deal and the deadline; it picks the colours, layout and copy, and matches your logo. Prefer to do it yourself? The editor takes a minute.
The timer’s image link, copied, or the timer added to the Black Friday campaign in Mailchimp.
Step 2
Copy one link, or let us put it in.
No code, no plugin, no developer: paste one image link anywhere. Or connect Klaviyo, Mailchimp, HubSpot and more (Pro and up), pick a campaign, and flashtimer puts the timer in for you.
Northward’s email, “Black Friday: 40% off everything we make”, with its live countdown timer, which shows an ended message once the sale is over.
Step 3
It counts down in every inbox.
Any campaign, flow or template. Each reader sees the real time left, in their language, and when the sale ends it shows your “offer ended” message instead of 00:00:00.
Works with
- Klaviyo
- Shopify
- Mailchimp
- HubSpot
- Omnisend
- ActiveCampaign
- Brevo
- MailerLite
and anywhere an email can hold an image. See every integration
Your first timer takes about a minute. No card.

Why flashtimer
The countdown, rebuilt for how you sell now.
Other timer tools stop at drawing a clock. flashtimer builds it from a sentence, puts it in your campaign, gives every reader their own deadline and tells you which version sold more.

| Capability | flashtimer | Most timer tools |
|---|---|---|
| Included | Cached, 1 min+ | |
Why it matters:There's no stored copy to be behind. A reader who opens at 11:58 sees two minutes left, not a picture from 11:56, and the image is sent no-store, so Gmail and Apple Mail are told never to keep an old one. | ||
| Included | Not offered | |
Why it matters:A finished timer in seconds, without a designer or a hunt through templates. | ||

AI-native
Describe the sale. flashtimer builds the timer.
In the dashboard, one sentence becomes a scheduled timer in your brand's colours, and changes work the same way: attach your logo and the colours come from it. Or hand the whole job to the AI assistant you already use.
From your AI assistant
Give your AI assistant the job.
Connect flashtimer once and ask from the chat you already work in. It makes the timer, puts it in your campaign once you say yes, extends the sale when it's going well, and tells you how it did.
- Uses design_timer.
- Uses preview_campaign_embed then embed_timer_in_campaign, after you allow it.
- Uses update_timer.
- Uses get_analytics.
Works in Claude, ChatGPT, Gemini, Grok and any other MCP client. Available on Pro and up.
Everything a timer needs
Built for the inbox.
Email is a hostile place for anything live. These are the parts that make a countdown work there, and keep working after the sale ends.
