Countdown timers

Countdowns show the active deadline for a promo. Use them to make the same campaign state visible on landing pages, sales pages, and emails.

Page countdown

<div data-plandalf-promo="early-bird"></div>

The SDK scans the page and mounts the promo widget into that element.

Pair with a checkout button

<div data-plandalf-promo="early-bird"></div>

<button
  data-plandalf-present="summit-ticket"
  data-plandalf-apply-promo="early-bird"
>
  Buy before the deadline
</button>

The first element renders the countdown. The button opens the offer and applies active promo-tier pricing.

Email countdowns

Email clients cannot run JavaScript, so email countdowns use an image URL generated by the countdown service.

<img
  src="https://countdown.plandalf.dev/acme/promo/early-bird.gif?pf_ref={{subscriber.email}}"
  alt="Time left"
>

Use pf_ref for participant tracking in links and countdown image URLs.
