Your CRM Has Garbage In It.
Here's What to Do.

Bad emails, duplicate contacts, info@ addresses, free Gmail domains, and contacts with titles like "student" — they all waste outreach effort and hurt deliverability. LeadClean runs your CRM export through 6 quality checks, scores every row 0-100, and outputs a clean CSV. $29 one-time, no API key needed.

What LeadClean checks

Email Validation

Syntax check, domain format, missing @ — flags emails that would immediately bounce without making an API call.

Duplicate Detection

Finds exact duplicates and near-duplicates (same email, different name fields). Prevents sending the same sequence twice to one contact.

Free Domain Flagging

Identifies Gmail, Yahoo, Hotmail, and 30+ free email providers. These are almost never B2B buyers — flag them for review or removal.

Role Classification

Classifies job titles into decision maker / manager / not a buyer based on a keyword dictionary. Prioritize your outreach on who can actually buy.

Missing Fields

Flags rows missing email, company, first name, or other key fields. Shows you which contacts need enrichment before outreach.

Quality Score (0-100)

Each row gets a score based on all checks combined. Filter by score to focus on the cleanest segment of your list first.
