MailerLite countdown timer for every campaign and automation

To be fair to MailerLite: if you need one deadline, for one campaign, in your account time zone, its built-in Countdown block (in the drag-and-drop editor's sidebar under Special) does the job at no extra cost. MailerLite's own help notes it renders as a GIF and that some older Outlook versions show it as a static image, which is true of every email GIF timer, ours included.

flashtimer is worth adding when you need more than one fixed date. You get evergreen timers that start at each subscriber's first open, recurring deadlines, cycle and count-up timers, a fallback image after the deadline, every layout with your own fonts, labels in multiple languages, view analytics and, on Business, countdown timer A/B tests. The same timer also works in any other platform you use.

• One deadline for everyone: MailerLite's Countdown block or flashtimer, both work.
• A per-subscriber window in an automation: flashtimer evergreen (Basic and up).
• A deadline that resets daily or weekly: flashtimer recurring (Basic and up).
• Each subscriber's own date, such as a trial end: flashtimer dynamic timers (Pro and up).

An evergreen timer gives every subscriber the same window, say 72 hours, starting when they first open. flashtimer needs to know which subscriber is opening, so the URL carries ?vid={$email}. MailerLite swaps in the subscriber's address when it sends, and flashtimer hashes the value before storing it.

Because MailerLite has to substitute the variable, check that it resolved: send a test, open it, and the timer should show the full window. If two different subscribers share one countdown, the variable was not replaced, usually because it was edited or pasted somewhere MailerLite doesn't personalize. See how the clock works on the evergreen countdown timer email page.

MailerLite automations send the same email to people on different days, which is exactly where a fixed date fails. An evergreen timer in the first email of a welcome automation lines up a welcome discount countdown for every new subscriber, whenever they join. A cart or browse reminder gets a 24- or 48-hour window per person.

For something that genuinely repeats, like a weekly live session or a daily shipping cutoff, a recurring countdown timer is honest where a reset trick is not: it always points at the next real deadline in your time zone and never ends.

The timer works in Gmail, Apple Mail, Yahoo, Outlook on the web, Mac and mobile, and every client that shows images. Classic Outlook for Windows (2007–2019, and newer versions with Windows animations turned off) shows only the first frame: the correct time left at the moment of opening, without ticking. Apple Mail Privacy Protection pre-fetches images. By default those loads get the live countdown as it stood then; on Pro and up, Apple Mail options can show them a message, your fallback image or nothing instead, so cached opens never show a stale time.

When the countdown ends, readers see your expiry message or, from Basic up, your own fallback image, so nobody opens a week late to a countdown for a finished sale. Match your MailerLite template with brand colors, custom fonts on paid plans and a transparent background; the custom branded countdown timer page has the details.

Almost every problem comes from the image being copied rather than linked, or the variable not being filled in. Check these before anything else.

• The timer doesn't move: the GIF was imported into MailerLite as a file, which freezes it. Point the image at the flashtimer URL or paste the HTML snippet.
• Every subscriber sees the same evergreen countdown: {$email} was not replaced. Re-copy the MailerLite embed and send a fresh test.
• Send to ESP can't see your drafts: the API key's account is not on MailerLite Advanced, or the campaign isn't a draft. The paste method works on any plan.
