To link your emails together without logging in to each account individually, you can follow these steps based on the information provided:
Set Up Account Linking in Gmail: Choose one of your Gmail accounts as the primary account. Log into this account and navigate to "Settings" > "See all settings" > "Accounts and Import". Here, under "Send mail as:", click "Add another email address", entering the details of the secondary email address you wish to link. Verify the secondary email address by following the instructions sent to it.
Forward Emails to Your Primary Account: For each email account you want to link, go to its settings, find the "Forwarding and POP/IMAP" section, and select "Add a forwarding address". Enter your primary Gmail account's address here. Confirm the forwarding address using the code received.
Sending Emails as Another Account: Still in the "Accounts and Import" settings of your primary Gmail account, under "Send Mail As", you can add more email addresses. This allows you to send emails from your primary account as if they were sent from the secondary accounts. Verify each secondary email address as prompted.
Use Multiple Inboxes Feature: To better manage emails from different accounts, enable the "Multiple Inboxes" feature in your primary Gmail account's settings. This creates separate sections within your primary inbox for emails from different accounts, allowing you to prioritize and manage them efficiently.
Organize Forwarded Emails Using Labels: Utilize Gmail's filtering and labeling features to easily identify and organize emails forwarded from different accounts. Create filters based on the "To" field matching your secondary email addresses and apply labels accordingly.
