The website only sees the separate address
Use a dedicated address when signing up instead of submitting your real email directly.
Stay connected, keep addresses separate
Separate website relationships with different receiving addresses
Shopping sites, communities, newsletters, and projects don't need to know the same address. Trace where an address was exposed and cut off only the affected connection when it turns sour.
Understand the four steps of address separation
A separate address isn't a second public inbox. It's a relationship boundary between a website and your private email.
The system receives and checks it
Incoming mail passes basic security rules while essential status and timing details are recorded.
It reaches your verified destination
Messages are sent to a private email address you have confirmed, so you don't need to keep reopening the website.
Control each source separately
When unwanted mail appears, pause the relevant identity while other connections continue normally.
Use-case matrix
Use different entry points for short-term, ongoing, and important relationships
Choose based on the task's risk and how long you expect to stay in touch—not one address for everything.
| Task | Temporary address | Separate forwarding address | Long-term email |
|---|---|---|---|
| One-time download or trial | Recommended | Usable | Usually unnecessary |
| Shopping and newsletters | Not convenient for ongoing use | Recommended | Usable, but the source is harder to identify |
| Communities and long-term projects | Not suitable | Recommended | Suitable for important relationships |
| Banking, healthcare, and government | Not suitable | Use with caution | Recommended |
| Testing email templates | Recommended for short tests | Suitable for ongoing regression tests | No need to expose your primary address |
How it works
Verify the destination first, then assign a public identity
One receiving destination can manage multiple identities, each with its own status, creation time, and delivery count.
Verify your receiving email
Enter an email address you control and enter the six-digit verification code; no separate password is required.
Create a prefix without sensitive information
Name it by purpose, but leave out your name, birthday, and account number; leave it blank to generate one at random.
Check the delivery trail
Filter records from the past 30 days by status, retry failed deliveries, and restore false positives.
Disable precisely
Pause a single identity instead of changing your real email, then delete it when you no longer need it.
Limitations
Separating public addresses doesn't eliminate every email risk.
Your details may still identify you
If payment details or message content reveal your real identity, separating addresses cannot anonymize the entire relationship.
Keep recovery access for important accounts
Use a long-term email address first for financial, healthcare, government, and core work accounts.
Delivery depends on multiple parties
The sender's server, the network, and the recipient's mailbox can all cause delays or rejection.
Records are not permanent archives
Delivery history is kept for only the past 30 days; save important content in your own systems.
