How to Merge Two or Multiple Yahoo Email Accounts

If you're thinking of combining Yahoo email accounts, you're probably tired of switching between two or more inboxes, or you may want to eliminate the multiple email addresses and keep only one.

Unfortunately, Yahoo is yet to offer the option of actually merging email accounts, but depending on your goals, you may choose one of the following options:

  • Option 1. Copy the emails from the secondary accounts into your primary Yahoo account and then delete the unwanted accounts. You can consider this option if you have multiple Yahoo accounts but want to keep only one email address. This will merge your email from multiple accounts.

  • Option 2. Use Yahoo's account switcher to access all your accounts from Yahoo Mail without having to log in and out. To view other inboxes, you'll need to open the email list by clicking your name at the top right of your primary inbox. This will not merge your emails from multiple accounts in one inbox.

In this article, we'll walk you through these options and will explain what

Option 1: Merge Yahoo accounts by copying emails into one account

You can copy your emails from secondary Yahoo addresses into your primary account automatically or manually.

We recommend using the automatic option because it is quicker and easier than the manual process, and it provides accurate results.

The manual option takes more time and involves installing additional software, and the results may not meet your expectations. But if you have a small account and know how to fix possible issues, you may also consider this option.

How to copy emails manually using a third-party email app

Alert symbol

This method has important limitations, which will be described further below. Please consider them carefully before you start.

To copy your Yahoo emails from your secondary accounts into the primary one using this method, you must install a third-party email app (such as Thunderbird or Outlook) on your computer.

Here's how you can copy your emails using the app:

  1. Connect your secondary account to the app.

    Use the following settings to configure the app:

    IMAP/SMTP settings for Yahoo
    Settings for connecting Yahoo to a desktop email app

    If you're using Yahoo Account Key, generate an app password and use it as your account password.

  2. Go to the Import/Export menu and download your email archive in a .mbox file. (The screenshot below has been made in Outlook. The Import/Export menu in other email apps may be different.)

    Step 2 of merging Yahoo accounts manually. Exporting a .pst file

    Step 2: Download your email
  3. Connect your primary Yahoo email account to the app.

  4. Select your primary account and go to the Import/Export menu.

  5. Import the downloaded .mbox file from the secondary Yahoo account to the primary account. This will upload your email archive to the primary account.

  6. If you have multiple Yahoo addresses that you want to merge, repeat the steps above for each of the secondary accounts.

    Alternatively, you can connect your secondary and primary accounts and then drag and drop emails between them.

Please note that the steps outlined above will make the email from your secondary accounts available in your primary account even if you delete the app after you've finished.

But there are some limitations that you should consider before you start:

  • You will need to make sure that you have enough free storage space on your hard drive for temporary copies of your secondary Yahoo inboxes.

  • Depending on the size of your secondary Yahoo accounts, the manual process may take up to several days (sometimes even weeks).

  • Manual migration is notoriously unreliable and some of the files may be lost during the copying process. The accuracy of the export and import may be compromised if power supply and broadband connection are interrupted.

  • The copying process may slow down the work of your computer and increase power consumption.

After you've finished copying your emails, you can delete the unneeded Yahoo accounts.

Option 2: Combine Yahoo accounts using the account switcher

Yahoo's account switcher will make it easier for you to access all your Yahoo accounts from one place. You will be able to switch between the accounts by selecting them from the list. While this will not merge the contents of your accounts, you won't have to sign in and out each time you need to access your secondary email addresses.

You can add up to 10 addresses using Yahoo's account switcher.

Here's how you can set the account switcher:

  1. Sign in to your primary Yahoo account.

  2. Click your profile image and select "Add or Manage accounts".

  3. Click "Add another account".

Frequently asked questions about merging Yahoo Mail accounts

How do I transfer Yahoo Mail to another account?

Yahoo Mail does not offer its users the ability to move Yahoo Mail to another account using Yahoo's native tools. For this reason, you can export your emails using a desktop email app such as Thunderbird or Outlook and then import them into another account. However, this method has lots of disadvantages and is not generally recommended. An alternative is to use a paid third-party migration tool that will allow you to copy the messages automatically.

How do I merge Yahoo Mail to Gmail inbox?

While it is not possible to fully merge your Yahoo Mail and Gmail inboxes, you can either add your Yahoo Mail account to Gmail or transfer your Yahoo Mail emails to Gmail and close the Yahoo account. Both methods have their limitations. With the first method, it will not be possible to import custom folders, and you may have trouble linking the two accounts. The second method is intended to copy the messages only once and not keep the accounts in sync. For more information about the second method, see this article: How to Transfer Emails from Yahoo to Gmail.

Can I forward Yahoo Mail to Gmail?

As of January 15, 2021, Yahoo Mail no longer offers the functionality to forward email automatically for free accounts. To be able to set up forwarding rules for your Yahoo Mail account, you need to upgrade to Yahoo Mail Pro or, for US only accounts, subscribe to Access + Forwarding.

Conclusion

If you wish to make a Yahoo mail merge, first you should consider what you want to achieve. You may want to merge your email from multiple accounts, or you may simply need to access all your inboxes from one location.

If you have two Yahoo mail accounts and you want to delete one, you may wish to merge the contents of your Yahoo accounts and get rid of the unwanted ones. In this case, you'll need to migrate email from your secondary accounts to the primary account before you delete the unused account. This can be done automatically using 3-rd party migration software or manually using a desktop email app. We recommend that you use VaultMe to merge your email accounts as an automatic option. VaultMe is quick, easy to use, and reliable.

If you want to keep all email addresses and access all accounts from one place, you can set up Yahoo's account switcher. With the account switcher, you'll have a list of your email addresses that you can scroll through and select accounts from.
