Validate Emails

How It Works

  1. Paste one or multiple email addresses.
  2. The validator checks syntax and structure rules.
  3. It flags disposable, role-based, and free-provider addresses.
  4. Copy the valid-only list for clean exports.

Email Validation Guide

What Gets Validated

  • One-and-only-one @ symbol rule
  • Valid local-part and domain syntax
  • Length limits for local part and full email
  • Disposable domain detection
  • Role-based address detection (admin, support, info)

Why It Matters

Better deliverability: Remove malformed addresses before sending.

Cleaner CRM data: Keep contact lists normalized and reliable.

Improved lead quality: Filter disposable and generic role addresses.
