AWS SES Send Email to Multiple Recipient using Python

I am new to AWS Lambda function.

I wanted to send email to multiple recipients. I am able to send email to single email address but not multiple email ids and shows error.

I just refered the amazon documentation page and wrote the below code.

I am using environmental variable runteam and it has values like ['[email protected]','[email protected]','[email protected]']

import boto3
import os
import os, sys, subprocess
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.application import MIMEApplication

def lambda_handler(event,context):

    ses = boto3.client("ses")
    s3 = boto3.client("s3")
    runemail = os.environ['runteam']
    for i in event["Records"]:
        action = i["eventName"]
        #ip = i["requestParameters"]["soruceIPAddress"]
        bucket_name = i["s3"]["bucket"]["name"]
        object = i["s3"]["object"]["key"]

    fileObj = s3.get_object(Bucket = bucket_name, Key = object)
    file_content = fileObj["Body"].read()

    sender = "[email protected]"
    to = runemail
    subject = str(action) + 'Event from ' + bucket_name 

    body = """
        <br>
        This email is to notify regarding {} event
        This object {} is created
    """.format(action,object)

    msg = MIMEMultipart('alternative')

    msg["Subject"] = subject
    msg["From"] = sender
    msg["To"] = ', '.join(runemail)

    body_txt = MIMEText(body, "html")
    attachment = MIMEApplication(file_content)
    attachment.add_header("Content-Disposition","attachment", filename = "ErrorLog.txt")
    msg.attach(body_txt)
    msg.attach(attachment)
    response = ses.send_raw_email(Source = sender, Destinations = rumemail, RawMessage = {"Data": msg.as_string()})
    return "Thanks"

I think everything seems to be right regarding the email sending code. The error lies in your program where the way you store your environ variable.

It should be stored as runteam="[email protected] [email protected] [email protected]" (notice the space between each email)

Then use this variable as
rumemail = os.environ['runteam'].split()

msg["To"] = ', '.join(runemail)

response = ses.send_raw_email(Source = sender, Destinations = rumemail, RawMessage = {"Data": msg.as_string()})

Removing/commenting out the following line should fix the issue:

msg["To"] = ', '.join(runemail)

By the above line, you are converting a list to a string. However, Destinations attribute is looking for a list.

This line:

msg["To"] = ', '.join(runemail)

is expecting a Python list, not a string. I suggest you add a debug line after it to see what you are actually sending the system.

I would recommending passing your environment variable as:

[email protected], [email protected], [email protected]

Then, use:

msg["To"] = runemail
