\ud83c\udfaf Project<\/strong> Objective<\/strong><\/h3>\n\n\n\n

To automate sending personalized emails using Python \u2014 ideal for newsletters, notifications, or reports.<\/p>\n\n\n\n

\n\n\n\n

\ud83e\udde9 1. Overview<\/strong><\/h2>\n\n\n\n

Automated emails are used in almost every business \u2014 from confirmation messages to marketing campaigns.<\/p>\n\n\n\n

\ud83d\udcbc Real-World Use Cases<\/strong><\/h3>\n\n\n\n
    \n
  • Sending automated invoices<\/strong> or payment reminders<\/strong><\/li>\n\n\n\n
  • Emailing daily reports<\/strong> from a script<\/li>\n\n\n\n
  • Sending marketing or newsletter campaigns<\/strong><\/li>\n\n\n\n
  • Notifying users about system alerts<\/strong> or status updates<\/strong><\/li>\n<\/ul>\n\n\n\n
    \n\n\n\n

    \u2699\ufe0f 2. Required Libraries<\/strong><\/h2>\n\n\n\n

    We\u2019ll use built-in and common modules:<\/p>\n\n\n\n

      \n
    • smtplib<\/code> \u2192 To send emails<\/li>\n\n\n\n
    • email.mime<\/code> \u2192 To format messages (text, HTML, attachments)<\/li>\n\n\n\n
    • pandas<\/code> \u2192 To read contact lists from CSV<\/li>\n<\/ul>\n\n\n\n

      \u2705 Auto-install if missing<\/strong><\/p>\n\n\n\n

      import subprocess, sys\n\ndef install(package):\n    try:\n        __import__(package)\n    except ImportError:\n        subprocess.check_call([sys.executable, \"-m\", \"pip\", \"install\", package])\n\ninstall(\"pandas\")\n<\/code><\/pre>\n\n\n\n
      \n\n\n\n
      \ud83d\udcec 3. Basic Email Sending<\/strong><\/h2>\n\n\n\n
      import smtplib\nfrom email.mime.text import MIMEText\n\ndef send_basic_email(sender, password, recipient, subject, message):\n    msg = MIMEText(message, \"plain\")\n    msg[\"From\"] = sender\n    msg[\"To\"] = recipient\n    msg[\"Subject\"] = subject\n\n    with smtplib.SMTP(\"smtp.gmail.com\", 587) as server:\n        server.starttls()\n        server.login(sender, password)\n        server.send_message(msg)\n        print(f\"\u2705 Email sent successfully to {recipient}\")\n<\/code><\/pre>\n\n\n\n
      \ud83e\uddea Example:<\/h3>\n\n\n\n
      send_basic_email(\n    \"youremail@gmail.com\",\n    \"your_app_password\",\n    \"friend@example.com\",\n    \"Python Automation Test\",\n    \"This email was sent automatically using Python!\"\n)\n<\/code><\/pre>\n\n\n\n
      \u26a0\ufe0f Tip:<\/strong>
      If you\u2019re using Gmail, you must use an App Password<\/strong>, not your regular password.<\/p>\n\n\n\n
      \n\n\n\n
      \ud83d\udc8c 4. Send HTML Emails<\/strong><\/h2>\n\n\n\n

      \ud83e\uddea Example:<\/h3>\n\n\n\n
      send_email_with_attachment(\n    \"youremail@gmail.com\",\n    \"your_app_password\",\n    \"client@example.com\",\n    \"Monthly Report\",\n    \"Please find the attached report.\",\n    \"report.pdf\"\n)\n<\/code><\/pre>\n\n\n\n
      \n\n\n\n
      \ud83d\udcca 6. Send Bulk Emails from CSV<\/strong><\/h2>\n\n\n\n
      import pandas as pd\n\ndef send_bulk_emails(sender, password, csv_file, subject, message):\n    contacts = pd.read_csv(csv_file)\n\n    for index, row in contacts.iterrows():\n        recipient = row[\"email\"]\n        personalized_message = message.replace(\"{name}\", row[\"name\"])\n        send_basic_email(sender, password, recipient, subject, personalized_message)\n<\/code><\/pre>\n\n\n\n
      \ud83e\uddea Example:<\/h3>\n\n\n\n
      # contacts.csv:\n# name,email\n# John,john@example.com\n# Sara,sara@example.com\n\nsend_bulk_emails(\n    \"youremail@gmail.com\",\n    \"your_app_password\",\n    \"contacts.csv\",\n    \"Hello from Python!\",\n    \"Dear {name},\\n\\nThis is a personalized email sent automatically.\"\n)\n<\/code><\/pre>\n\n\n\n
