Bulk Email Validation & Verification Service

What Clearout is

Clearout is an email verification tool in the B2B go-to-market stack. In the vendor's own words: “Bulk Email Validation & Verification Service.” Put plainly, a tool in this category checks an address before you send to it, so bounces never reach your domain.

Where it sits in an outbound stack

Most outbound stacks are four layers: the data that decides who you talk to, the channel that carries the message, the writing that earns a reply, and the system of record that remembers what happened. Clearout sits in the email verification layer. Tools beside it are worth comparing on coverage and price; tools in the other layers are worth wiring to it rather than replacing it with.

Using Clearout with M for Mercury

Clearout is a data layer, and data is where LinkedIn outreach either works or wastes a sender. Mercury's Lead Finder searches 450M+ contacts and returns the LinkedIn profile to connect with alongside a verified work email, then enriches whatever is missing column by column. If Clearout already holds your list, Mercury takes it from there: enrol the audience in a journey, spread it across senders, and pace every send inside safe limits.
