How to send multiple recipient sendgrid V3 api Python - python-3.x

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 = " xxx#gmail.com, yyy#gmail.com".

Answer 1

Note that with the code of the other answers here, the recipients of the email will see each others emails address in the TO field. To avoid this one has to use a separate Personalization object for every email address:
def SendEmail():
sg = sendgrid.SendGridAPIClient(api_key="YOUR KEY")
from_email = Email ("FROM EMAIL ADDRESS")
person1 = Personalization()
person1.add_to(Email ("EMAIL ADDRESS 1"))
person2 = Personalization()
person2.add_to(Email ("EMAIL ADDRESS 2"))
subject = "EMAIL SUBJECT"
content = Content ("text/plain", "EMAIL BODY")
mail = Mail (from_email, subject, None, content)
mail.add_personalization(person1)
mail.add_personalization(person2)
response = sg.client.mail.send.post (request_body=mail.get())
return response.status_code == 202

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='sender#example.com',
to_emails=[To('test#example.com'), To('test2#example.com')],
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='sender#example.com',
to_emails=[To('test#example.com'), To('test2#example.com')],
subject='Subject line',
text_content='This is the message of your email',
is_multiple=True # Avoid listing all recipients on the email
)

To send email to multiple recicpent in sendgrid v3.
import time
import sendgrid
import os
print "Send email to multiple user"
sg = sendgrid.SendGridAPIClient(apikey='your sendrid key here')
data = {
"personalizations": [
{
"to": [{
"email": "adiii#gmail.com"
}, {
"email": "youremail#gmail.com"
}],
"subject": "Multiple recipent Testing"
}
],
"from": {

"value": "<h3 style=\"color: #ff0000;\">These checks are silenced please check dashboard. Click HERE</h3> <br><br> <h3>For any query please contact DevOps Team<h3>"
}
]
}
response = sg.client.mail.send.post(request_body=data)

if response.status_code == 202:
print "email sent"

You can update your code in the below way. You can find the same in mail_example.py present in Sendgrid's package.
personalization = get_mock_personalization_dict()
mail.add_personalization(build_personalization(personalization))
def get_mock_personalization_dict():
"""Get a dict of personalization mock."""
mock_pers = dict()
mock_pers['to_list'] = [Email("test1#example.com",
"Example User"),
Email("test2#example.com",
"Example User")]
return mock_pers
def build_personalization(personalization):
"""Build personalization mock instance from a mock dict"""
mock_personalization = Personalization()
for to_addr in personalization['to_list']:
mock_personalization.add_to(to_addr)
return mock_personalization

Based on Subhrajyoti Das answer, I wrote the following code, that is a simpler version of the mail_example.py example of sending email to multiple recipient.
def SendEmail():
sg = sendgrid.SendGridAPIClient(api_key="YOUR KEY")
from_email = Email ("FROM EMAIL ADDRESS")
to_list = Personalization()
to_list.add_to (Email ("EMAIL ADDRESS 1"))
to_list.add_to (Email ("EMAIL ADDRESS 2"))
to_list.add_to (Email ("EMAIL ADDRESS 3"))
subject = "EMAIL SUBJECT"
content = Content ("text/plain", "EMAIL BODY")
mail = Mail (from_email, None, subject, content)
mail.add_personalization (to_list)
response = sg.client.mail.send.post (request_body=mail.get())
return response.status_code == 202

Answer 6

You can pass a list of strings.
message = Mail(
from_email='sender#email.com',
to_emails=['xxx#email.com', 'yyy#email.com'],
subject='subject',
html_content='content')
sg = SendGridAPIClient('SENDGRID_API_KEY')
response = sg.send(message)
