When you upload or use your customer lists, Salesgenie’s built-in email hygiene service automatically validates your email addresses. The system scans each address and flags invalid ones, known as “hard bounces.” These invalid addresses are automatically removed from your campaigns, so you won’t waste time or money sending to them.

This process ensures that your uploaded lists stay clean, your sender reputation is protected, and your campaigns only go to addresses with a higher chance of being delivered.
