How To Safely Switch Your Email Accounts Without Losing Data

Switching an old email account may look like a daunting task as you might worry about losing previous email messages, contacts, and other data in the process.

If you have two email accounts from the same email service, you can just add the other account to the same profile and switch whenever you want. However, if you want to switch across different platforms; say Gmail and Outlook, it takes a little longer before you can migrate to the new account.

To safely switch email accounts, you basically do two things; import data from the old account and then set up a forwarding mechanism to receive all the upcoming email messages in the new account.

How to Switch from One Gmail Account to Another Gmail/Outlook Account?

To move emails and contacts from your old Gmail account to the new one, you must first enable POP access on the old one. Then, you can start importing all emails and contacts into the new account. Finally, you can set up automatic forwarding to receive every mail from the old account to the new one.

Step 1: Configure Essential Settings on the Old Gmail Account

First, sign in to your old Gmail account.
Click the gear icon in the top-right corner and select See all settings.
Under the Forwarding and POP/IMAP tab, select the Enable POP for all mail option.

Then, under the When messages are accessed with POP section, select the delete Gmail’s copy option to delete the old messages after copying them to the new account. Or, if you wish to keep the old account and its messages, select other options according to your preferences.

Note: Alternatively, you can also set up IMAP and use it to switch to another Outlook account. On the same Forwarding section, you can find the necessary configuration instructions next to the IMAP access field.

Step 2: Import All the Old Email Messages and Contacts to the New Account

Log in to your new Gmail account and open its settings, like in the above steps.
Then, under the Accounts and Import tab, click Import mail and contacts.
On the next prompt, enter the old email address (Gmail) you want to import from.
Log in to the old account when prompted and allow the necessary permissions.
When you reach the Import options window, select the options to import old and new upcoming emails /contacts from the old account. Then, click Start import.

Note: The import process can take some time depending on the number of emails and contacts you have on the old account.

Step 3: Forward Every Mail From the Old Account to the New One

If you don’t want to delete the old email account, but still keep receiving every new mail from it on the new account, you can set up mail forwarding.

Login to the old Gmail account from whose emails you want to forward.
Go to the Gmail settings.
Under Forwarding and POP/IMAP, click Add a forwarding address.

On the next prompt, enter the new email address (Gmail or Outlook) you want to use and click Next.

On the next prompt, click Proceed.
Open the verification mail link on the new email address. Then, click Confirm.
Now, go to the old Gmail account and under the Forwarding and POP/IMAP section, make sure you have selected the Forward a copy of incoming mail to option with the new email address. Also, select “delete Gmail’s copy” to skip the old account and get all the upcoming messages in the new account. Or, if you want to save a copy in the old account, select other available options.
Click Save Changes.

Note: You can even create a filter that forwards a particular type of email you receive on the old account.

Step 4: Update All the Accounts Linked to the Old Email Address

Once you have configured all the necessary settings to use the new Gmail account, consider updating all the accounts which are previously linked to the old email address.

On the other hand, notify other people about your new email address so that they send emails to your new account. Since it isn’t convenient to notify each person manually, you can set up an auto-reply in Gmail. By doing so, they can reach out to you on your new Gmail account.

Log in to your old Gmail account.
Go to the Gmail settings.
Under the General tab, scroll down to the bottom and select the Vacation responder on option.
Write a message to automatically reply and notify the senders about your new email address. Configure other options according to your preferences.
When done, click Save Changes.
