Why is google mail combine ither

I think you meant to ask "Why does Google Mail combine other accounts?"

Google Mail, also known as Gmail, allows you to combine multiple email accounts into a single inbox. This feature is called "Multiple Inboxes" or "Unified Inbox". Here are some reasons why Google implemented this feature:

  1. Convenience: Combining multiple accounts into one inbox makes it easier to manage your emails. You can access all your emails from a single place, without having to switch between different accounts.
  2. Organization: With multiple inboxes, you can organize your emails by account, label, or category. This helps you keep your emails organized and easy to find.
  3. Simplification: Combining accounts eliminates the need to log in and out of multiple accounts, making it easier to manage your email workflow.
  4. Integration: Google's Multiple Inboxes feature allows you to use Gmail's advanced features, such as filters, labels, and search, across all your accounts.
  5. Security: By combining accounts, you can use Gmail's robust security features, such as two-factor authentication and encryption, to protect all your emails.

To combine multiple accounts in Gmail, follow these steps:

  1. Sign in to your Gmail account.
  2. Click on the gear icon in the upper right corner and select "See all settings".
  3. Go to the "Accounts and Import" tab.
  4. Click on "Add a POP3 mail account" or "Add a non-Gmail account".
  5. Enter the email address and password of the account you want to add.
  6. Follow the prompts to set up the account.

Once you've added the account, you can switch between inboxes by clicking on the account name in the top right corner of the Gmail window.
