HOW IT WORKS

Silence, made actionable.

Arm a countdown. Check in to keep it quiet. Miss the deadline and your pre-armed actions fire — automatically, to the people and systems that need to know.

  1. 01
    ARM A COUNTDOWN

    Set the interval, choose the trigger.

    Pick a check-in window — minutes to weeks — or a fixed deadline. Then decide what fires if you miss it: email, SMS, or webhook.

  2. 02
    CHECK IN TO RESET

    One tap and the clock starts over.

    A tap, an email link, an SMS reply, or an API call resets the timer to full. As long as you check in, nothing happens.

  3. 03
    GO SILENT, IT TRIGGERS

    Miss the deadline. Everything fires.

    When the countdown hits zero, your pre-armed actions execute automatically — reaching every recipient and endpoint you set.

No silence goes unanswered.

FAQ

Common questions.

What is CountdownTrigger?

CountdownTrigger is an automated messaging service. You set a countdown timer and check in regularly. If you miss a check-in, your pre-written emails or texts are sent automatically to your chosen contacts.

How does checking in work?

You can check in through your dashboard, by clicking a link in a reminder email, via SMS reply, or through our API. Each check-in resets your countdown timer.

What happens if I miss a check-in?

When your countdown reaches zero, your configured actions trigger automatically. This could be sending emails, SMS messages, or calling webhooks. Your contacts receive your pre-written messages.

Is my data secure?

Yes. Your messages are encrypted and stored securely. We use industry-standard security practices and never share your data with third parties.

Can I cancel or pause my countdown?

Absolutely. You can pause, edit, or cancel your countdown at any time from your dashboard. Paused countdowns won't trigger until you resume them.

What if your service goes down?

Our infrastructure runs on AWS with multiple redundancies. In the unlikely event of an outage, your countdowns are preserved and will trigger as scheduled once service resumes.

Can I try it for free?

Yes! The free plan includes 1 active countdown with email and SMS notifications and check-in intervals up to 2 hours. No credit card required to get started.
