How to Setup Undisclosed Recipients in Yahoo!Mail

One of the most popular free email provider we know is Yahoo!Mail. A spam is definitely the most hated email we could ever get because it is unsolicited which normally comes in bulk and since we’re also concerned of our security especially to those identity thefts.

In order for us to prevent ourselves from these unscrupulous spam bots, I have come to discover how we can get rid of spam by teaching our friends or those people we know how to undisclosed their contacts email addresses in case they’ll be sending bulk emails. This is easy to setup and can be done in just a minute, no software or program needed.

So here’s how to do it,

First, sign in to your Yahoo!Mail as you see below:

After signing in, navigate to your right status bar

then press “Add Contact”, to add a new contact.

From the Add Contact page, fill out the boxes as shown below:

Note: only the fields below should be filled out, nothing else.

After filling out the boxes shown above, hover down to the bottom right of the page then click, “Save”.

Afterwards, click “Done” to confirm the added contact.

So, we have already created a contact under the name “Undisclosed recipients”.

This is done to create an undisclosed recipient contact that would shadow the email addresses of the recipients in cases of sending an email to many recipients.

Now, how do we apply “Undisclosed recipients” for multiple messages to be sent? Click “Compose” to create an email.

From your address book, tick the box next to “Undisclosed recipients“.

then, remember to click “Show Bcc” so that the email addresses of the recipients will be blind copied. What will happen is that, each receiver will see ONLY the sender’s email address but will not know the email addresses to whom the sender also sent the same email.
That is why it’s marked “undisclosed”.

See what it would look like below:

On the “Bcc” box is where you should be typing all the recipients email addresses.

Then, click “Send”.

So, from here we’re able to know how we can get rid of spammers, spam bots or with some people we don’t know who might be the spammers within our midst.

    When filling out the new contact page, who’s email address is filled in this field?

  4. Mathdelane says:

    @Spiderman069, thanks for visiting. On the new contact page, fill it in with “Undisclosed” and “recipients” as the first and last name, respectively. But do not forget that the email associated with the contact name “Undisclosed recipients” should be your own email address as this is necessary in order to send the email and you must not be confused after sending bulk emails and receiving something for yourself since the recipients’ email addresses are to be written only on the BCC section. I hope this helps. Let me know if you still have any questions.

    I have followed your instructions exactly and cannot get it to work. It still shows my email address in the TO: field when I send emails.

  6. Mathdelane says:

    Hi Brenda, Thanks for visiting my blog. The main requirement is to create a contact name with “Undisclosed recipient” that should be associated with your email. The reason is, the “Undisclosed recipient” contact name with be the anchor email so you can send bulk email under the BCC field so normally every recipient including yourself will see your email in the To: field but not the rest of the other email addresses who have received the same email. If you still have clarifications, don’t hesitate to ask.

    Hi, thanks for this info you share… i just want to clarify that, the contact “Undislosed Recipients” will be used to shadow the other recipients, so that the “Undislosed Recipients” will only be visible in the To: of the received email. Am I right bout this sir?

    And one more thing, these steps you mention are also applicable in Gmail (Google Mail)?

    thanks again and God Bless…

    Absolutely right!

    For Gmail, I haven’t tried it but you may check it out and tell me if it works. 🙂 For Outlook Express and MS Outlook, it does work fine too.
