How to gmail mail export to 2nd mailbox

There are a few ways to export Gmail emails to a second mailbox. Here are a few methods:

Method 1: Using Gmail's built-in feature

  1. Log 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 "Export" and select "Export mail and contacts."
  5. Choose the mailbox you want to export from and select the date range you want to export.
  6. Click "Export" and follow the prompts to download the exported emails as a CSV file.
  7. Log in to your second mailbox and import the CSV file using the mailbox's import feature.

Method 2: Using IMAP

  1. Log in to your Gmail account.
  2. Enable IMAP in your Gmail settings (Settings > Forwarding and POP/IMAP > Enable IMAP).
  3. Log in to your second mailbox and set up an IMAP account.
  4. Use an IMAP client (such as Microsoft Outlook or Mozilla Thunderbird) to connect to your second mailbox.
  5. Use the IMAP client to fetch emails from your Gmail account and transfer them to your second mailbox.

Method 3: Using a third-party service

  1. Sign up for a third-party service that allows you to export Gmail emails, such as Sanebox or Boomerang.
  2. Follow the service's instructions to export your Gmail emails.
  3. Log in to your second mailbox and import the exported emails using the mailbox's import feature.

Method 4: Using a script

  1. Use a scripting language like Python or Ruby to connect to your Gmail account using the Gmail API.
  2. Write a script that fetches emails from your Gmail account and transfers them to your second mailbox.
  3. Run the script to export the emails.

Here's an example of how you could use Python and the Gmail API to export emails:

import os
import json
from google.oauth2.credentials import Credentials
from googleapiclient.discovery import build

# Set up credentials
creds = Credentials.get_credentials()
service = build('gmail', 'v1', credentials=creds)

# Set up the mailbox you want to export from
mailbox = '[email protected]'

# Set up the mailbox you want to export to
target_mailbox = '[email protected]'

# Fetch emails from the mailbox
response = service.users().messages().list(userId=mailbox).execute()
messages = response.get('messages', [])

# Loop through each email and transfer it to the target mailbox
for message in messages:
    message_id = message['id']
    message_body = service.users().messages().get(userId=mailbox, id=message_id).execute()
    message_body = message_body.get('payload', {}).get('body', {}).get('text', '')
    # Use an IMAP client or a third-party service to transfer the email to the target mailbox
    # For example, you could use the `imaplib` library in Python to connect to the target mailbox and send the email
    #...

Note that this is just an example and you will need to modify it to fit your specific use case. Additionally, be aware that exporting large numbers of emails can be time-consuming and may require additional setup and configuration.
