Automate Email Sending with Python: Complete Guide with Attachments

You send the same types of emails every week. Status reports to your team. Invoices to clients. Reminders to stakeholders. Each one takes a few minutes—minutes that add up to hours.

Let Python send your emails while you focus on work that actually matters.

What You'll Learn

Sending emails with Python's built-in libraries
Using Gmail and other email providers
Adding HTML formatting for professional emails
Attaching files (PDFs, Excel, images)
Creating email templates for reuse

Prerequisites

Python 3.8 or higher
An email account (Gmail recommended for this tutorial)
App Password for Gmail (we'll show you how to set this up)

The Problem

Manual email tasks that eat your time:

Weekly status reports to multiple recipients
Sending invoices or documents to clients
Reminder emails on schedules
Bulk notifications to teams
Personalizing repetitive emails

The Solution

A Python script that:

Connects to your email provider
Composes professional emails (plain text or HTML)
Attaches files when needed
Sends to one or multiple recipients
Can be scheduled to run automatically

Step 1: Setting Up Gmail App Password

For security, Gmail requires an "App Password" instead of your regular password:

Go to your Google Account (myaccount.google.com)
Select Security on the left
Under "Signing in to Google," select 2-Step Verification (enable if not already)
At the bottom, select App passwords
Select app: "Mail" and device: "Other (Custom name)"
Enter a name like "Python Email Script"
Click Generate
Copy the 16-character password (you'll only see it once!)

Important: Store this password securely, never in your code.

Step 2: Sending a Simple Email

Let's start with the basics:

python

1import smtplib
2from email.mime.text import MIMEText
3from email.mime.multipart import MIMEMultipart
4
5def send_simple_email(to_email, subject, body):
6    """
7    Send a simple text email.
8    
9    Args:
10        to_email: Recipient email address
11        subject: Email subject line
12        body: Email body text
13    """
14    # Your email credentials
15    sender_email = "your.email@gmail.com"
16    app_password = "your-16-char-app-password"  # Use environment variable in production!
17    
18    # Create the email
19    message = MIMEMultipart()
20    message["From"] = sender_email
21    message["To"] = to_email
22    message["Subject"] = subject
23    
24    # Attach the body
25    message.attach(MIMEText(body, "plain"))
26    
27    # Connect to Gmail and send
28    try:
29        with smtplib.SMTP_SSL("smtp.gmail.com", 465) as server:
30            server.login(sender_email, app_password)
31            server.sendmail(sender_email, to_email, message.as_string())
32        
33        print(f"✅ Email sent to {to_email}")
34        return True
35        
36    except Exception as e:
37        print(f"❌ Failed to send email: {e}")
38        return False
39
40# Example usage
41send_simple_email(
42    to_email="colleague@company.com",
43    subject="Quick Update",
44    body="Hi,\n\nJust wanted to share a quick update on the project.\n\nBest regards"
45)

Step 3: Sending HTML Emails

Plain text is fine, but HTML emails look professional:

python

1def send_html_email(to_email, subject, html_content, plain_text=None):
2    """
3    Send an HTML formatted email with plain text fallback.
4    
5    Args:
6        to_email: Recipient email address
7        subject: Email subject line
8        html_content: HTML body content
9        plain_text: Optional plain text alternative
10    """
11    sender_email = "your.email@gmail.com"
12    app_password = "your-16-char-app-password"
13    
14    message = MIMEMultipart("alternative")
15    message["From"] = sender_email
16    message["To"] = to_email
17    message["Subject"] = subject
18    
19    # Plain text version (for email clients that don't support HTML)
20    if plain_text:
21        message.attach(MIMEText(plain_text, "plain"))
22    
23    # HTML version
24    message.attach(MIMEText(html_content, "html"))
25    
26    try:
27        with smtplib.SMTP_SSL("smtp.gmail.com", 465) as server:
28            server.login(sender_email, app_password)
29            server.sendmail(sender_email, to_email, message.as_string())
30        
31        print(f"✅ HTML email sent to {to_email}")
32        return True
33        
34    except Exception as e:
35        print(f"❌ Failed to send email: {e}")
36        return False
37
38# Example HTML email
39html = """
40<html>
41<body style="font-family: Arial, sans-serif; line-height: 1.6;">

67    to_email="team@company.com",
68    subject="Weekly Status Report - Week 45",
69    html_content=html
70)

Step 4: Adding Attachments

Emails often need attachments—reports, invoices, images:

python

1from email.mime.base import MIMEBase
2from email import encoders
3import os
4
5def send_email_with_attachment(to_email, subject, body, attachment_paths):
6    """
7    Send an email with one or more attachments.
8    
9    Args:
10        to_email: Recipient email address
11        subject: Email subject line
12        body: Email body text
13        attachment_paths: List of file paths to attach
14    """
15    sender_email = "your.email@gmail.com"
16    app_password = "your-16-char-app-password"
17    
18    message = MIMEMultipart()
19    message["From"] = sender_email
20    message["To"] = to_email
21    message["Subject"] = subject
22    
23    # Add body
24    message.attach(MIMEText(body, "plain"))
25    
26    # Add attachments
27    for filepath in attachment_paths:
28        if not os.path.exists(filepath):
29            print(f"⚠️ Attachment not found: {filepath}")
30            continue
31        
32        filename = os.path.basename(filepath)
33        
34        # Read and encode the file
35        with open(filepath, "rb") as f:
36            attachment = MIMEBase("application", "octet-stream")
37            attachment.set_payload(f.read())
38        
39        encoders.encode_base64(attachment)
40        attachment.add_header(
41            "Content-Disposition",
42            f"attachment; filename={filename}"
43        )
44        
45        message.attach(attachment)
46        print(f"📎 Attached: {filename}")
47    
48    try:
49        with smtplib.SMTP_SSL("smtp.gmail.com", 465) as server:
50            server.login(sender_email, app_password)
51            server.sendmail(sender_email, to_email, message.as_string())
52        
53        print(f"✅ Email with attachments sent to {to_email}")
54        return True
55        
56    except Exception as e:
57        print(f"❌ Failed to send email: {e}")
58        return False
59
60# Example usage
61send_email_with_attachment(
62    to_email="client@company.com",
63    subject="Monthly Report - November 2025",
64    body="Hi,\n\nPlease find the monthly report attached.\n\nBest regards",
65    attachment_paths=["./reports/november_2025.pdf", "./reports/summary.xlsx"]
66)

Step 5: Using Email Templates

Create reusable templates for common emails:

python

1def load_template(template_name, **kwargs):
2    """
3    Load an email template and fill in placeholders.
4    
5    Args:
6        template_name: Name of the template
7        **kwargs: Values to substitute into template
8    
9    Returns:
10        Tuple of (subject, html_content)
11    """
12    templates = {
13        "weekly_report": {
14            "subject": "Weekly Report - {week_date}",
15            "html": """
16            <html>
17            <body style="font-family: Arial, sans-serif;">

19                <p>Hi {recipient_name},</p>
20                <p>Here's the weekly summary for {week_date}:</p>

22                <h3>Highlights</h3>

24                    {highlights}

7set EMAIL_PASSWORD=your-16-char-app-password

Save the script as email_automation.py
Run the script:
bash
```
1python email_automation.py
```

Customization Options

Use Other Email Providers

python

1# Outlook/Office 365
2SMTP_SERVER = "smtp.office365.com"
3SMTP_PORT = 587
4# Use STARTTLS instead of SSL:
5# with smtplib.SMTP(SMTP_SERVER, SMTP_PORT) as server:
6#     server.starttls()
7
8# Yahoo
9SMTP_SERVER = "smtp.mail.yahoo.com"
10SMTP_PORT = 465

Add CC and BCC

python

1def create_email_with_cc(to, cc, bcc, subject, html):
2    message = MIMEMultipart()
3    message["To"] = to
4    message["Cc"] = cc
5    # BCC is not added to headers
6    
7    # When sending, include all recipients:
8    all_recipients = [to] + cc.split(",") + bcc.split(",")
9    server.sendmail(SENDER_EMAIL, all_recipients, message.as_string())

Schedule Emails

Combine with task scheduling:

python

1# Run at 9 AM every Monday
2# Add to crontab: 0 9 * * 1 /usr/bin/python3 /path/to/email_automation.py

Common Issues & Solutions

Issue	Solution
Authentication failed	Check app password; ensure 2FA is enabled
Connection timeout	Check firewall; try different port
Emails going to spam	Use proper HTML; avoid spam trigger words
Attachments not showing	Check file paths; verify files exist
Special characters broken	Use UTF-8 encoding for MIMEText

Taking It Further

Read Replies with IMAP

python

1import imaplib
2import email
3
4def check_inbox():
5    """Read emails from inbox."""
6    mail = imaplib.IMAP4_SSL("imap.gmail.com")
7    mail.login(SENDER_EMAIL, SENDER_PASSWORD)
8    mail.select("inbox")
9    
10    _, messages = mail.search(None, "UNSEEN")
11    
12    for num in messages[0].split():
13        _, data = mail.fetch(num, "(RFC822)")
14        msg = email.message_from_bytes(data[0][1])
15        print(f"From: {msg['from']}")
16        print(f"Subject: {msg['subject']}")
17    
18    mail.close()
19    mail.logout()

Email Queue with Retry

python

1import json
2from datetime import datetime
3
4def queue_email(email_data, queue_file="email_queue.json"):
5    """Add email to send queue."""
6    try:
7        with open(queue_file) as f:
8            queue = json.load(f)
9    except FileNotFoundError:
10        queue = []
11    
12    email_data["queued_at"] = datetime.now().isoformat()
13    email_data["attempts"] = 0
14    queue.append(email_data)
15    
16    with open(queue_file, "w") as f:
17        json.dump(queue, f)
18
19def process_queue(queue_file="email_queue.json", max_attempts=3):
20    """Process queued emails with retry logic."""
21    # Implementation for processing queue
22    pass

Conclusion

You now have a complete email automation system. Send reports, notifications, and personalized bulk emails—all with professional HTML formatting and attachments.

The key is the template system. Once you create templates for your common email types, sending them becomes a single function call. Combine this with scheduling, and your routine email tasks happen automatically.

Start with one email you send regularly. Automate it. See how much time you save. Then expand to more. Before long, you'll wonder how you ever managed without it.

Your inbox, automated.
