## What it does

The server exposes email marketing records from over 800 online stores across Germany and the Nordic region. It connects via streamable HTTP. AI assistants query three read-only tools: `get_brand_summary`, `get_brand_email_frequency`, and `find_brands`. These return weekly send averages across 90 days, campaign dates within 31-day windows, and up to two recent subject lines.

The underlying archive tracks promotional campaigns exclusively. It strips out receipts and welcome sequences. Metrics like open rates or revenue remain completely outside the dataset. If a brand sits outside the monitored catalogue, the endpoint flags it immediately instead of inventing dates.
