How to send a error mail in success mail

You want to send an error mail in addition to a success mail. This is a common requirement in many applications.

Here are a few ways to achieve this:

Method 1: Using a separate error mail template

Create a separate email template for error messages (e.g., error_email_template.html or error_email_template.txt).
In your code, when an error occurs, use the error mail template to send an email with the error details.
When the operation is successful, send the success mail using a different template (e.g., success_email_template.html or success_email_template.txt).

Method 2: Using a single email template with conditional logic

Create a single email template that includes conditional logic to display error messages or success messages based on the outcome of the operation.
In your code, when an error occurs, set a flag or variable to indicate that an error occurred.
In the email template, use conditional statements (e.g., if statements) to display the error message or success message based on the flag or variable.

Method 3: Using a notification service

Use a notification service like Sendgrid, Mailgun, or AWS SES to send emails.
Configure the notification service to send a separate email for errors and another for success.
In your code, when an error occurs, trigger the error email notification service.
When the operation is successful, trigger the success email notification service.

Here's some sample code in Python using the smtplib library to illustrate Method 1:

import smtplib
from email.mime.text import MIMEText

# Define email templates
error_email_template = """
Subject: Error: {error_message}

Dear {user},

An error occurred: {error_message}
"""

success_email_template = """
Subject: Success: {success_message}

Dear {user},

The operation was successful: {success_message}
"""

# Define email settings
email_settings = {
    'from': '[email protected]',
    'to': '[email protected]',
    'server': 'smtp.example.com',
    'port': 587,
    'username': 'your_email_username',
    'password': 'your_email_password'
}

# Send email
def send_email(subject, message, user):
    msg = MIMEText(message)
    msg['Subject'] = subject
    msg['From'] = email_settings['from']
    msg['To'] = email_settings['to']

    server = smtplib.SMTP(email_settings['server'], email_settings['port'])
    server.starttls()
    server.login(email_settings['username'], email_settings['password'])
    server.sendmail(email_settings['from'], email_settings['to'], msg.as_string())
    server.quit()

# Example usage
if __name__ == '__main__':
    try:
        # Perform operation
        #...
        send_email('Success: Operation completed', success_email_template.format(success_message='Operation completed successfully'), 'John Doe')
    except Exception as e:
        send_email('Error: Operation failed', error_email_template.format(error_message=str(e)), 'John Doe')

In this example, when an error occurs, the send_email function is called with the error email template and the error message. When the operation is successful, the send_email function is called with the success email template and a success message.
