How to Create a Yahoo Email Alias: FAQ

Can I make the Yahoo email aliases the same as my Yahoo email address, only with an extension?

No, the base name for disposable Yahoo email addresses (.e., aliases) needs to be different from the account's user name.

What you can do, of course, is

set up a Yahoo mail account with a user name and address you do not intend to use and
pick the desired "user name" as your alias base name.
Note: You will not be able to use the base name alone.
Example: If you set up me as the base name you can create
+ me-124@yahoo.com and
+ me-me@yahoo.com,
but you cannot receive and send emails using
– me@yahoo.com.

How should I use a Yahoo alias as a disposable email address?

If you choose to employ a Yahoo alias address as a disposable email address, it is best to:

Create a new and unique alias for each sender.
Example: Create an alias for each shop and each newsletter.
Use a meaningful extension or description that links the alias to the sender.
Note: This lets you identify the alias easily.
Never use an alias for more than one contact or sender.
Disable an alias as soon as it has been misused (e.g., starts receiving junk email, or will not let you unsubscribe effectively) to start blocking emails sent to it.

Can I make an alias the default sending address?

Yes. To configure an alias as your default email address for sending in Yahoo Mail:

Click the Settings Menu icon in Yahoo Mail in a desktop browser.
Follow the More Settings link.
Go to the Writing email category.
Under Default sending address, select the alias you want to use as your default address for new messages.
Tip: You can, of course, always select a different alias — or your account's default email address — for sending individual emails.

Can I filter mail received at an alias address?

Yes. To set up a filter that files incoming emsils sent to a Yahoo Mail alias address:

Click the Settings Menu icon in Yahoo Mail.
Select More Settings.
Go to the Filters category.
Click Add new filters.
Under Set rules, choose To/CC.
Choose contains.
Type your Yahoo alias address over Type a filter value.
Choose an action for the filter and click Save.

Will deleting an alias also delete emails received at the address?

No.

Yahoo Mail will not delete messages you have received through an alias in the past.

When you disable an alias address, future messages addressed to that alias will not reach your account, however.

What do senders receive when they mail a deleted Yahoo email alias?

Senders who email an alias address you have deleted receive an error message.

Specifically, they receive the SMTP error

554 delivery error: dd Not a valid recipient

during attempted delivery.

Can I restore a deleted alias address?

Yes.

If you have accidentally deleted a Yahoo Mail alias, you can reinstate the address and make it work again:

Create a new alias using the same extension. (See above.)

Messages that have been sent while the alias was not active are lost and will not be delivered to the inbox, but future emails will arrive.
