Domain expiring soon
If days until expiry is under 30 days, ensure auto-renewal is active with your registrar to prevent hijacking.
New domain trust risk
Domains younger than 6 months have lower default email deliverability and are more scrutinized by anti-spam filters.
Recommended remediation
Keep domains renewed for 2-5 years in advance. Established domain age signals trust to search engines and mail transfer agents.
