Why Cleaning Email Lists Matters
Sending emails to invalid or risky addresses can hurt your deliverability, waste your marketing budget, and damage your sender reputation. A clean list means more of your emails reach real people—and fewer end up in spam.
Types of Emails Explained
- Valid: Real, deliverable email addresses
- Invalid: Misspelled or non-existent addresses
- Disposable: Temporary emails used for one-time signups
- Role-based: Addresses like admin@, support@, info@—often not monitored by a real person
