## When to prefer this

Use this endpoint when you need a fast, low-cost ($0.01) single-domain check for Mailchimp specifically. Prefer this over bulk endpoints when checking one domain at a time or when you need detailed evidence snippets. Choose this over generic technology scanners when your workflow is specifically targeting email marketing stack detection for sales intelligence, competitor profiling, or migration planning.

## Known failure modes

- Domain is unreachable or returns a non-200 status, resulting in an error or inconclusive result
- Site uses server-side rendering that hides Mailchimp fingerprints from the static HTML response
- Mailchimp fingerprints may be absent on pages other than the homepage, causing a false negative
- Rate limiting or bot-protection on the target site may block the fetch
- Domain is entered without a valid TLD or is malformed, causing a fetch failure

## How this service works

Does a website use Mailchimp? Fetches the page (homepage for a bare domain) and matches Mailchimp's fingerprints in the HTML and response headers, returning yes/no with the evidence snippet and the category (email-marketing). Technographics for sales, competitor research and migration planning, one technology per call. $0.01 per check.

## Output

Returns a yes/no boolean indicating whether Mailchimp was detected on the site, along with the evidence snippet from the HTML or response headers that triggered the match, and the technology category label (email-marketing).
