What Clearout Email Verification is
Clearout Email Verification checks email addresses individually, in bulk, or through an API to help reduce bounces and keep lists clean. Its checks include mailbox validity, MX lookup, SMTP ping, spam trap detection, disposable address detection, and catch-all detection. You can verify one address, paste up to 10 addresses, or upload CSV/XLSX lists; results are grouped into categories such as Valid, Invalid, Catch-All, Disposable, and Role-Based. Verification modes include Fastest Turnaround, Highest Accuracy, and Deep Verify. The API supports individual and bulk checks, with webhooks to capture results when a workflow takes longer. Form Guard checks email, phone, and name fields in real time and can flag disposable emails, invalid phone numbers, gibberish, and profanity. Listed integrations include HubSpot, Mailchimp, MailerLite, ActiveCampaign, Zapier, Google Sheets, WordPress forms, and WooCommerce. New users receive 100 free credits. Valid, invalid, and catch-all results cost one credit; unknown results and duplicate addresses in the same uploaded list are not charged. The free plan is available; paid pricing starts at $16/mo (annual).
