Clearout Waterfall

Clearout helps improve accuracy and quality through advanced bulk list upload or integration options to cleanse email databases and mitigate risk of emailing dubious accounts. The platform offers a LinkedIn Chrome Extension to identify potential prospects and capture verified business email addresses, and enables enrichment by finding valid contact numbers. Waterfall enrichment is a B2B data enrichment method that queries multiple data providers sequentially until a verified email address, phone number, or contact detail is found. When results are returned from a provider, they pass through email verification including syntax validation, domain validation confirming active MX record, and SMTP verification confirming the specific mailbox exists and can receive mail. Tools using waterfall stack multiple providers to boost data coverage, accuracy, and deliverability, resulting in better email match rates, fewer bounces, and more verified phone numbers. Some platforms integrate data from top sources including Clearout to boost email list accuracy to 95%.
