My separate gmail accounts are merged into one inbox on iphone

Re: "My separate gmail accounts are merged into one inbox on iphone. I want them to be totally separate."

Seems the inbox collects all mail from all accounts, yet you can also view each account separately.

There are also ways to organize your eMail by creating / using different Mailboxes.

How to: Organize email in mailboxes on iPhone - Apple Support

also says how you can: View emails from one account at a time

If you use multiple email accounts with the Mail app, you can use the mailboxes list to view emails from one account at a time.

Tap  in the upper-left corner until you see Mailboxes, then tap a mailbox below the email account you want to access. Each mailbox listed below a particular email account only displays emails from that email account.

For example, to view only emails sent from your iCloud account, tap iCloud, then tap Sent.

You can flag an important email to make it easier to find later.

An email you flag remains in your Inbox and also appears in the Flagged mailbox.

To match a mail account to a Focus :

You can choose which email accounts to receive notifications from when a

Focus is on. For example, you can set a filter to show only your work email account and its notifications when your Work Focus is on.

On iPhone, you can add a Mail widget and customize which mailbox it shows on your Home Screen.

Choose between displaying recent unread emails, new emails from your VIPs, or any other mailbox.

To add a Mail widget, see Add, edit, and remove widgets on iPhone.

Hope this helps :-)

I would prefer the accounts to be separate.

Thanks
