Availability / BETA
Choose the boundary that matches the task.
SpotMail is free today. Open one inbox without an account, sign in for continuity, or use the Automation BETA for tests and agents. Every path stays temporary.
Available now
No checkout. No subscription. No invented paid tier.
The limits on this page describe the product as it works now. Future capacity and pricing will follow real usage—not a placeholder plan.
Access modes
Three ways in. One expiration rule.
Choose based on who controls the inbox. Signing in adds continuity; a Project Key adds automation. Neither turns temporary mail into permanent storage.
