## What can you do with it?

| Type | What it does |
| --- | --- |
| Personal alias | Another address that delivers to a person's mailbox. |
| Temporary alias | An address that expires after the number of days you set. Created from webmail. |
| Domain alias | A domain address that forwards to one or more destinations. |

## When should you use it?

- Receive `sales@` or `support@` in someone's mailbox without creating another paid mailbox.
- Hand out a throwaway address for a one-off sign-up.
- Share a domain address among several people.

## How does it work in ArduMaker?

Aliases live on the mail server. A domain alias must end in `@` plus the domain name; otherwise it is rejected. Before deleting an alias, ArduMaker checks that it belongs to that mailbox or domain: if it cannot check because the server does not answer, it does not delete.

## What actually changes?

The alias is created or deleted on the mail server. Billing does not change: an alias is not a mailbox.

## Expected result

Mail sent to the alias shows up in the destination mailbox like any other message.

## Errors and troubleshooting

- **`alias_address_is_required`**: the alias address is missing.
- **`validity_days_is_required`**: a temporary alias needs its validity in days.
- **`alias_not_found`**: the alias does not belong to that mailbox or domain.
- **`dependencia_caida`**: the mail server did not answer while checking the alias. Safe to retry.

## MCP access

Requires access to the domain's company. See [/mcp/correo](https://ardumaker.com/en/mcp/correo).

| Type | Tools |
| --- | --- |
| Read | `listar_alias_correo`, `listar_alias_dominio_correo` |
| Modify | `crear_alias_correo`, `crear_alias_dominio_correo` |

Temporary aliases have no MCP tool: they are created from webmail.
