- URL: https://crestink.com/
- Locale focus: DACH (German-speaking markets)

## What it is
CrestInk is a planned weekly competitor briefing for DACH Email / MarTech teams.
It summarizes publicly visible competitor signals (plan and product pages, changelogs, blogs, and similar public sources), with sources cited.
Delivery intent: once per week, into the subscriber inbox — short, sharp, source-linked.

German framing on-site: „Wöchentliches Mitbewerber-Briefing“ / Bedürfnisforschung via free waitlist.

## What it is NOT
- Not an ESP, CRM, or agent dashboard
- Not a ranking, scoreboard, or win-rate / ROI promise product
- Not sales calls, book-a-demo, or cold outreach
- Not legal, tax, investment, or marketing advice
- Not personalized competitive intelligence yet: the public Montags-Sample is a shared baseline example

The offer is free. Do not invent offer tiers or packages.
