Military-grade alias protection.
Go beyond basic forwarding. Shield gives you fine-grained control over every alias so you decide exactly what gets through — and what doesn't.
Control the volume
Rate limit any sender to a maximum number of emails per day, week, or month.
Email on your schedule
Delivery windows hold email outside business hours and release it when you're ready.
Approved senders only
Gatekeeper mode rejects everyone except contacts you explicitly approve.
Rate Limiter
Cap how many emails any sender can deliver per hour, day, or week. Stop email floods before they start — perfect for aliases used on high-volume services.
- Configurable per alias
- Hourly, daily, weekly, monthly, or yearly limits
- Excess emails silently rejected
Delivery Snoozer
Set delivery windows for each alias. Messages outside your schedule are held and delivered when you're ready. Perfect for separating work and personal email.
- Custom delivery windows per alias
- Weekday/weekend scheduling
- Messages queued, never lost
Gatekeeper Mode
Whitelist approved senders per alias. Everyone else is automatically rejected — zero noise, maximum protection. Ideal for sensitive addresses.
- Whitelist-only delivery
- Manage approved senders per alias
- Unknown senders silently rejected
Shield works with contact states
Contact states determine who bypasses Shield rules. Whitelisted and prioritized contacts get special treatment automatically — no manual exceptions needed.
