Short answer
Retiring one forwarding address is a sequencing problem, not a deletion problem. Before you stop the alias, confirm that no account still uses it to sign in or to receive password resets. Then choose between pausing the address and deleting it permanently.

That reversibility is the reason to pause first. A pause gives you a test window: if a forgotten service still writes to the alias, you can restore it and fix that login instead of losing the address.
Permanently deleting an inactive Hide My Email address cannot be undone; emails to a stopped address are returned to the sender. Source
Know which address you are retiring
Hide My Email addresses and addresses created with Sign in with Apple are different mechanisms, even though both can forward mail. Do not assume that removing or changing one affects the other. If your signup records do not make clear which mechanism produced an address, treat it as unresolved and check the account itself before acting.
This article covers one alias only. It is not a method for enumerating every alias attached to an account.
Decision table
| Situation | Safer action | Why |
|---|---|---|
| Alias still appears in a login or password-reset path | Keep it active; update that account first | Losing the address can lock you out of recovery |
| You are unsure whether a service still uses it | Deactivate rather than delete | Deactivation can be reversed |
| All known logins and recovery paths are moved | Permanent deletion is reasonable | Deletion cannot be undone |
| You only want less forwarding noise | Deactivate | Same reversibility, less commitment |
| The address came from Sign in with Apple | Treat separately from Hide My Email | The two mechanisms are distinct |
Self-review checklist
- Search your password manager and inbox for the alias string, not just the service name.
- List every account where it is the sign-in address, the recovery address, or both.
- Move sign-in addresses first, then recovery addresses.
- Confirm each change with a test reset or notification before moving on.
- Keep a recovery method you control until every dependent account is updated.
- Only then decide: deactivate, or delete permanently.
- After deactivation, watch for bounce-backs or missed mail before committing to deletion.
Removing a login connection or editing a profile does not by itself delete data stored by that service. Closure is a separate step you take on the service’s own terms, and this page does not promise that any external service will delete anything.
Where username searches fit
A username search is not a complete account inventory. It can surface public matches that remind you which services you once joined, but public matches are leads, not proof of ownership, and it does not see private information or change settings anywhere. TraceSeek checks 3,000+ platforms, a first scan is free, and the stated scan time is 20-30 seconds. Use it to jog your memory, then verify each candidate account directly.
