Publish to get your embed code. Every email open fetches a fresh GIF showing the true remaining time — timezone-exact for fixed dates, per-recipient for evergreen timers.
Dynamic tip: set the deadline per email with your ESP's merge tag — e.g. …?d={{campaign_deadline}}. Accepts ISO YYYY-MM-DDTHH:mm or a Unix epoch (seconds); add &tz= only if the date isn't in the timer's zone.
Evergreen tip: Gmail's image proxy can hide recipients' addresses, so add your ESP's merge tag to the timer URL for exact per-recipient countdowns — e.g. …?u={{email}}. Without it, recipients are told apart by network fingerprint.
