How to send multiple recipient sendgrid V3 api Python

Question

Anyone please help, I am using sendgrid v3 api. But I cannot find any way to send an email to multiple recipients. Thank in advance.

    import sendgrid
    from sendgrid.helpers.mail import *

    sg = sendgrid.SendGridAPIClient(apikey="SG.xxxxxxxx")
    from_email = Email("FROM EMAIL ADDRESS")
    to_email = Email("TO EMAIL ADDRESS")
    subject = "Sending with SendGrid is Fun"
    content = Content("text/plain", "and easy to do anywhere, even with Python")
    mail = Mail(from_email, subject, to_email, content)
    response = sg.client.mail.send.post(request_body=mail.get())
    print(response.status_code)
    print(response.body)
    print(response.headers)

I want to send email to multiple recipient. Like to_mail = " [email protected], [email protected]".

You can send an email to multiple recipients by listing them in the to_emails parameter of the Mail constructor:

from sendgrid import SendGridAPIClient
from sendgrid.helpers.mail import *

message = Mail(
    from_email='[email protected]',
    to_emails=[To('[email protected]'), To('[email protected]')],
    subject='Subject line',
    text_content='This is the message of your email',
)

sg = SendGridAPIClient(SENDGRID_API_KEY)
response = sg.send(message)

With this configuration, each recipient will be able to see each other listed on the email. To avoid this, use the is_multiple parameter to tell Sendgrid to create a new Personalization for each recipient:

message = Mail(
    from_email='[email protected]',
    to_emails=[To('[email protected]'), To('[email protected]')],
    subject='Subject line',
    text_content='This is the message of your email',
    is_multiple=True  # Avoid listing all recipients on the email
)
