Can I upgrade or downgrade anytime?
Canceling stops renewal while paid access continues through the end of your current billing period. Your workspace moves to Free after that date.
What happens if I exceed my email limit?
We'll notify you when you approach your monthly email limit. Enterprise customers can set custom overage and volume agreements.
When should I choose Enterprise?
Choose Enterprise when you need custom throughput, private deployment, dedicated routing, SSO, procurement support, or compliance review before agents can process mail.
