Tickdown makes live countdown timers for email campaigns. Pick from 17 designer looks, set your deadline and timezone, and paste one hosted GIF into any email's HTML block. No plugin, no scripts, no developer. Every open shows the exact time left, and when the clock hits zero the image switches to your own expiry message, so late openers never see a dead offer. Run fixed timers for launches and flash sales, evergreen daily deadlines for ongoing campaigns, or personal timers that pass each recipient's deadline in the URL. Tickdown works with Mailchimp, Klaviyo, HubSpot, Brevo and any ESP that accepts an image. Developers and AI assistants can create timers through the API and MCP server. Start free with no account; Pro is $6/month and Business $19/month. Built by Level 114 LTD in the UK for agencies, Shopify brands, events, courses and SaaS teams.
