Method 2: Using the Gmail API

To enable multiple mail sending using the Gmail API, you will need to:

Here is an example of how to send an email from multiple addresses using the Gmail API in Python:

import base64
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 email message
message = MIMEMultipart()
message['From'] = '[email protected]'
message['To'] = '[email protected]'
message['Subject'] = 'Test email'
message.attach(MIMEText('This is a test email'))

# Set up the email addresses to send from
send_from_addresses = ['[email protected]', '[email protected]']

# Send the email
for send_from in send_from_addresses:
    message['From'] = send_from
    raw_message = base64.urlsafe_b64encode(message.as_string().encode('utf-8'))
    service.users().messages().send(userId='me', body={'raw': raw_message.decode('utf-8')}).execute()
