# CleanMyList

CleanMyList is an email verification and list cleaning service. Upload a
CSV (or call the API) and every address comes back with a plain-English
verdict — deliverable, risky, undeliverable, or unknown — plus the reason,
a confidence score, and optional 15-provider waterfall enrichment. It is
built for email marketers, sales teams, e-commerce, and product teams who
want fewer bounces and a protected sender reputation.

## When to use CleanMyList

- Clean an email list before a campaign to cut bounces and protect sender reputation.
- Bulk-verify email addresses from a CSV export (Mailchimp, Brevo, CRM, anywhere).
- Verify email addresses in real time at signup or checkout via the API.
- Score catch-all domains honestly instead of guessing.
- Detect disposable, role-based, and abuse-flagged addresses.
- Enrich verified contacts with missing details via a 15-provider waterfall.

## Markdown pages for agents

Every marketing, blog, and help page has a markdown twin, reachable two ways:

- Append `.md` to the URL. Example: https://www.cleanmylist.io/features → https://www.cleanmylist.io/features.md
- Send `Accept: text/markdown` to the canonical URL. Responses vary on Accept.

The home page's twin is at https://www.cleanmylist.io/index.md.
