3. 3Add ContextGate to your AI app as a connector or MCP server. The steps for each app are on the Works with page.
4. 4Paste a signup email into your AI app and ask Clearout whether it's disposable or a free webmail address, then check Activity for the call.

Check an address before you send

• Verify a single address instantly, or check whether it's disposable, catch-all, gibberish, free or a business account.
• Look up a person from an email address or a LinkedIn URL.
• Turn a company name into its likely domain and pull the company's profile.
• Check a domain's MX records or WHOIS record.
• See your remaining verification credits before a big run.

Guardrails for contact data

• Switch off the bulk upload and reverse-lookup tools and keep single checks.
• Policies can hide personal data in results, such as the name attached to an email address.
• Activity records each verification, so you can see which addresses were checked and when.
