Typo addresses (like "gmal.com" instead of "gmail.com") can harm your deliverability. Here's how to manage them:

1. Prevention Methods:

• Implement double-entry email fields

• Disable copy-paste functionality

• Use real-time email validation

• Implement Bird’s Recipient Validation
  
  

2. Use Signals Data:

• Create Signals report filtered to ‘Othermail provider’

• Toggle off ‘top domains only’

• Sort by acceptance rate to identify top sent-to typo domains
  
  

3. Maintenance Steps:

• Remove hard bounces promptly

• Regular list cleaning

• Monitor bounce patterns

• Audit signup forms regularly
