Overview

Upload a CSV or paste a list of emails to validate syntax, check domain records, and identify risky addresses, helping you reduce bounce rates and improve campaign performance.

A clean email list is the foundation of any successful marketing or sales campaign. Sending to outdated, invalid, or risky email addresses doesn't just waste money—it actively damages your sender reputation, causing your messages to land in spam folders even for valid recipients. This tool scrubs your email lists by performing a series of checks on each address. It goes beyond simple syntax validation (like checking for the '@' symbol). It verifies that the domain exists and has valid mail exchange (MX) records, checks for disposable or temporary email providers, and identifies role-based accounts (e.g., `sales@`, `info@`) that often have low engagement. ### How it helps your business For marketers, this means higher open rates, better campaign ROI, and a healthier sender score. For sales teams, it means more of your outreach emails actually reach their intended prospects. For agencies, it's a critical step in managing client campaigns and providing a valuable list hygiene service. The tool processes lists in bulk via CSV upload or a direct list paste. The output provides clear, actionable categories: a list of `clean_emails` that are safe to send, a list of `invalid_emails` that should be removed immediately, and breakdowns of other categories like `catch_all` (servers that accept all mail, making verification uncertain) and `disposable`. You also receive detailed statistics on the overall quality of your list, helping you understand its health at a glance.
