Budget-conscious users who want unlimited aliases and open-source transparency. Great for privacy-focused alias creation at minimal cost.
Cleanbox is the better choice if you need spam filtering before delivery, contact management with 20 automatic categories and 5 contact states, Shield protection (rate limiting, delivery scheduling, gatekeeper), or MX relay for existing business email addresses with virus scanning.
3 aliases, spam filtering, contact management, and Shield — no credit card required.
