DATA LIFECYCLE
Every piece of data has a boundary—from address creation to automatic expiry
Temporary inboxes and long-term forwarding follow different lifecycles. This roadmap shows retention periods, your control, and what we cannot promise.

LIFECYCLE ROADMAP
Collect, process, present, expire
Data minimization means more than collecting less: every piece of data has a defined purpose and an exit path. Temporary and forwarded mail stay in separate archives.
CreateThe service creates a temporary address, while your browser stores the address, token, and numeric expiry time needed for recovery.
ReceiveIncoming mail is routed by destination address; the temporary inbox displays messages only for the current short-term task.
ProcessForwarded mail is sent to your login email, while its status and body are kept in the dashboard for verification.
ExpireThe temporary inbox expires, a forwarding archive passes its retention window, or you delete an alias or individual message.
RETENTION & BOUNDARIES
Different data, different retention rules
| Data object | Purpose | Retention window | User controls |
|---|---|---|---|
| Temporary address and email | Current verification task | 3 hours by default, up to 24 hours | Extend, change address, delete individual messages |
| Forwarding alias | Keep your real address separate long term | While the account remains active | Copy, pause, resume, delete |
| Forwarded email archive | Check status and message body | 30 days | View, retry, mark, delete |
| Essential operational logs | Security, rate limiting, and troubleshooting | Only as long as necessary | Request through support |
What we can promise
We separate temporary and long-term features and show clear expiry and archive windows. Protected endpoints require a valid token, and email HTML is rendered in an isolated frame.
You can pause or delete aliases and manage archived email. We do not describe “no registration required” as complete anonymity, because networks and destination sites may still hold other identifiers.
What we cannot guarantee for you
We cannot control whether sending sites accept temporary domains, nor guarantee that internet delivery will never be delayed. Once an address expires, it cannot serve as a long-term recovery credential.
Do not use temporary email for banking, healthcare, government services, or irreplaceable documents. Keep important data in systems you control long term and that have recovery mechanisms.
SECURITY FAQ
Clear boundaries matter more than absolute claims
Can I recover a temporary email after it expires?
No. You can recover it from the same browser while it is valid, but after expiry the address is no longer a reliable entry point.
Are attachments stored in the temporary archive?
No attachments are retained. For an ongoing relationship that requires files, use a forwarding alias or a trusted mailbox.
What happens when I delete an alias?
You no longer control that entry point, and future mail should not be expected to reach it. Update the email address on related accounts before deleting it.
How do I submit a data request?
Email support@masksend.com with your account email and request type. Do not include your password or verification code.
