> Live countdown timers for email and the web. Add a real, ticking deadline to any email or landing page with one image URL — works in every ESP (Klaviyo, Mailchimp, HubSpot, Shopify Email + 50 more), no code. Fixed, per-subscriber evergreen, and auto-resetting recurring timers, with view analytics and a free plan (20,000 views/mo).

Tickvio (https://tickvio.com) is a countdown-timer platform. The marketing site hosts the product, pricing, features, ESP integrations, industry guides, countdown-to-date pages, free tools, and blog — fully localized in English, Spanish (es), German (de), French (fr), and Brazilian Portuguese (pt-BR). The app is at https://app.tickvio.com.

## Use Tickvio's free tools from an AI assistant (MCP)
- [MCP endpoint](https://tickvio.com/api/mcp): a stateless Streamable-HTTP Model Context Protocol server. No account or key needed — every tool is a free, deterministic computation. Tools:
  - days_until — time left until a date or a known retail/holiday event (Black Friday, Christmas, French soldes, Brazilian Carnaval, …).
  - list_countdown_events — the catalog of supported events + when each falls.
  - add_to_calendar — Google/Outlook links + an .ics file for a deadline.
  - check_subject_line — spam/urgency/length score for an email subject line.
  - countdown_timer_roi, cart_abandonment_roi — revenue estimates for adding a live countdown.
  Connect it in Claude or ChatGPT by adding the endpoint URL as a custom connector — the free tools need no account or key.
- Account tools (same endpoint, require sign-in): create/list/update/delete/duplicate real timers, timer view/click stats, and browse/favorite/create-from templates — scoped to your workspace. Authenticate with one-click OAuth 2.1 (the client prompts a Tickvio sign-in + consent) or a Tickvio API key (Settings → API keys).
