Clearout

@Clearout verify the email addresses in this CSV file and tell me how many are deliverable versus risky or invalid.

I've uploaded your CSV to Clearout for bulk verification (job ID: bv_abc123). The scan is now 100% complete. Out of 487 addresses: 412 are deliverable, 38 are risky (accept-all or role-based), and 37 are invalid (syntax errors or non-existent mailboxes). I can generate a download link for the full results file with per-row disposition codes if you'd like to import the cleaned list into your CRM.

This example shows bulk verification — a core use case for cleaning mailing lists before a campaign. The MCP polls job status automatically. Note that large files may take several minutes to process, and Clearout's API enforces rate limits on concurrent bulk jobs. You'll need sufficient API credits in your Clearout account.

@Clearout find work email addresses for the contacts in this spreadsheet using their names and company domains.

I've queued a bulk email finder job (job ID: ef_xyz789) with your 142 contacts. Clearout will attempt to locate verified work emails by cross-referencing names against known domain patterns and public sources. The job is currently 68% complete. Once finished, I'll provide a download link for a results file showing found emails, confidence scores, and any records where no email was discovered.

This example demonstrates prospecting — finding emails when you only have names and companies. Clearout's finder tools use pattern matching and web scraping, so results depend on the target domain's email format being discoverable. Expect partial coverage (not every contact will yield an email), and be aware that aggressive use may trigger rate limits.

@Clearout check whether john.doe@example.com is a business account or a personal freemail address, then verify its deliverability.

I've run two checks on john.doe@example.com. First, Clearout confirms it's a business account (the domain example.com is corporate, not a freemail provider like Gmail). Second, the deliverability check returns 'valid' — the mailbox exists and accepts mail, with no catch-all or disposable flags. This email is safe to use for B2B outreach.

This example pairs two single-email tools: business-account detection (useful for filtering out personal addresses in a B2B workflow) and real-time verification. These are synchronous calls, so they return instantly. Use this pattern when validating one-off addresses during form submission or lead qualification, rather than batch-processing a list.

When Clearout saves your sender reputation before a cold campaign

A 6-person sales team exports 2,000 leads from Apollo or Clay and needs to verify emails before loading them into Outreach. Clearout's bulk verify tool catches bounces, disposables, and role accounts in one pass—upload the CSV, poll the progress endpoint, download the scored results. The business account verify tool filters out free Gmail addresses that tank deliverability. This works if your list is under 10k rows and you can wait 5-15 minutes for the job to finish. Over that threshold, you'll want a dedicated email hygiene platform with real-time webhooks. If you send cold email at any volume, running Clearout verification before your first send is the difference between 92% deliverability and getting domain-blocked in week two.

How Clearout fills contact gaps in your ATS exports

A 3-person recruiting ops team pulls 500 passive candidates from LinkedIn Recruiter but only has company names and titles—no direct emails. Clearout's email finder tool takes first name, last name, and domain (autocompleted from the company field) and returns verified work emails with confidence scores. The bulk finder handles the full list in one job; you poll status, then download results with deliverability flags. This scenario wins when you're sourcing 200-1000 contacts per week and need better-than-guessing accuracy without manual lookup. If your volume is under 50 contacts a month, the per-lookup cost isn't worth the API integration. For mid-scale recruiting where you're stitching together partial contact data, Clearout turns incomplete records into sendable leads in under an hour.

Why Clearout matters for post-webinar follow-up accuracy

A 4-person marketing team runs monthly webinars and collects 300-800 registrations through Zoom or Eventbrite. Before syncing attendees to HubSpot for nurture sequences, they bulk-verify the email list to remove typos, spam traps, and fake entries that skew engagement metrics. Clearout's bulk verify job flags invalid syntax, catch-all domains, and disposable addresses in one pass—download the results, filter to 'valid' and 'accept_all', then import clean records. The business account verify step ensures you're not nurturing personal Gmail accounts when your ICP is enterprise buyers. This use case works if your event cadence is monthly or quarterly and you care about list quality over raw volume. If you're running daily webinars or don't segment by email type, the overhead isn't justified. For teams where a 15% invalid rate kills attribution and wastes sales time, Clearout is the pre-sync gate that keeps your CRM honest.
