Sometimes you need to understand how to whitelist an email from an entire domain rather than individual addresses:

• Use wildcard notation like "*@company.com" when implementing domain-level trust

Proactive Trust Management

Smart email management involves knowing how to whitelist an email proactively:

• Add important senders immediately upon first contact
• Trust domains of services you subscribe to when you first sign up
• Maintain a list of critical senders and regularly verify their trusted status

Advanced Troubleshooting Steps

When basic methods for how to whitelist an email fail, try these advanced approaches:
