Reminder emails are what actually get registrants to show up — and a live countdown turns "starts at 2 PM Eastern" into something visceral: starts in 3 hours. UrgencyKit renders the countdown as a standard image, so it works in Gmail, Outlook, and every other client your registrants use, with no JavaScript.
Because the image renders fresh on every open, the same embed URL stays accurate across every email in your sequence:
You build the timer once and paste it four times. No re-exporting, no per-email math — every open shows the real time remaining.
"2 PM Eastern" makes every registrant do mental math — and some get it wrong. A countdown shows time remaining, which is identical for every viewer everywhere. You set the start time and timezone once; every render is computed from it.
The moment the countdown hits zero, the timer switches to a custom expired state — an alternate image saying "We're live — join now", or a replay announcement for anyone opening late. Reminder emails sitting in inboxes never show a stale countdown.
Running evergreen or on-demand webinars where each registrant picks a slot? Replace the embed's
?end= value with your platform's merge tag holding each registrant's session time, and
every reminder counts down to that person's session. See how
evergreen countdown timers work.
Create a campaign with your webinar's start time, copy the image embed, and paste the same embed into every reminder. Each open renders the current time remaining.
The timer switches to a custom expired state — for example a "we're live, join now" image — so late opens never see a stale countdown.
Yes. Time remaining is the same for every viewer, so no one has to convert "2 PM Eastern" to their local time.
Yes — swap the ?end= value for a merge tag holding each registrant's session time.
