Email mit SMTPLib an mehrere Empfänger senden

Question

Wie kann ich mit SMTPLib in Python eine Email an mehrere Empfänger senden?

import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

# Email configuration
smtp_server = 'smtp.example.com'
smtp_port = 587
smtp_username = 'your_email@example.com'
smtp_password = 'your_password'

# Email content
from_email = 'your_email@example.com'
to_email = 'recipient@example.com'
subject = 'Test Email'
body = 'This is a test email sent using Python.'

# Create a MIME object
message = MIMEMultipart()
message['From'] = from_email
message['To'] = to_email
message['Subject'] = subject
message.attach(MIMEText(body, 'plain'))

# Send the email
try:
    with smtplib.SMTP(smtp_server, smtp_port) as server:
        server.starttls()  # Secure the connection
        server.login(smtp_username, smtp_password)  # Log in to the server
        server.sendmail(from_email, to_email, message.as_string())  # Send the email
    print('Email sent successfully.')
except Exception as e:
    print(f'Error: {e}')

Du kannst die Empfänger durch ein Comma getrennt angeben. In deinem Beispiel:

to_emails = ['recipient1@example.com', 'recipient2@example.com', 'recipient3@example.com'] 

Danach joinst du das Array zu einem Comma separierten String.

message['To'] = ', '.join(to_emails)

Hier der gesamte Code:

import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

# Email configuration
smtp_server = 'smtp.example.com'
smtp_port = 587
smtp_username = 'your_email@example.com'
smtp_password = 'your_password'

# Email content
from_email = 'your_email@example.com'
to_emails = ['recipient1@example.com', 'recipient2@example.com', 'recipient3@example.com']
subject = 'Test Email to Multiple Recipients'
body = 'This is a test email sent to multiple recipients using Python.'

# Create a MIME object
message = MIMEMultipart()
message['From'] = from_email
message['To'] = ', '.join(to_emails)
message['Subject'] = subject
message.attach(MIMEText(body, 'plain'))

# Send the email
try:
    with smtplib.SMTP(smtp_server, smtp_port) as server:
        server.starttls()  # Secure the connection
        server.login(smtp_username, smtp_password)  # Log in to the server
        server.sendmail(from_email, to_emails, message.as_string())  # Send the email
    print('Email sent successfully to multiple recipients.')
except Exception as e:
    print(f'Error: {e}')
