Countdown Builder

About Countdown Builder

Countdown Builder is a tool for marketers who want to add a live countdown clock to their email campaigns. Users pick from a library of templates, customize colors, fonts and labels, then copy a single HTML embed code into Mailchimp, Klaviyo, HubSpot or any platform that accepts HTML.

The timers are delivered as animated GIFs that regenerate each time an email is opened, so subscribers see the time remaining at that moment. Campaigns can use a fixed end date, an evergreen timer that starts when each subscriber opens the email, or a dynamic timer that takes a unique deadline per recipient through a merge tag.

The site highlights a free plan without watermarks, plus options such as urgency messages that change as the deadline nears, expiry states, and custom domains on higher tiers. It is aimed at e-commerce teams, launch marketers and anyone running flash sales or abandoned-cart emails.
