What can an AI teammate do with Reacher?

A Reacher AI teammate can verify individual email addresses, bulk-check entire lists, inspect domain deliverability, and retrieve past verification results. It can run automatically on a schedule (e.g. nightly list audits) or on demand (e.g. verify every new lead as it arrives). All verification actions are read-only, no email is ever sent during the process.

Does Reacher actually send emails to verify addresses?

No. Reacher uses SMTP handshakes, MX record lookups, and catch-all detection to determine deliverability without sending any message. This means no deliverability risk and no notification to the address being checked.

What is catch-all detection and why does it matter?

A catch-all domain accepts every email sent to it regardless of whether the mailbox exists, making standard SMTP checks unreliable. Reacher flags these domains so your AI teammate can mark those addresses as risky and exclude them from campaigns or segment them for separate treatment.

Can my AI teammate verify emails as leads come in?

Yes. You can configure a task that triggers on each new lead (via webhook or CRM sync) and calls Reacher to verify the address in real time. Invalid or risky addresses can be flagged, routed, or blocked automatically before they enter your pipeline.

AI Teammate for Reacher

An AI teammate that verifies email addresses and checks domain deliverability in real time.

Your AI teammate for Reacher performs real-time email verification using SMTP checks, MX record lookups, and catch-all detection, without ever sending an email. Use it to clean lists before campaigns, qualify leads on intake, and flag risky domains before they hurt your sender reputation. Write actions (if any) always require your approval.

Bad email addresses inflate bounce rates, damage sender scores, and waste campaign spend. Connecting Reacher lets your AI teammate silently verify every address before it touches your list, so you only send to real, deliverable inboxes.
