Usage

1. Sending a Simple Email

Below is a basic example of sending a plain text email:

from smtp_email_sender import EmailSender, email_text

# Initialize the EmailSender with your SMTP credentials.
sender = EmailSender(
    sender="[e-mail]",
    password="your_password",
    smtp_server="smtp.example.com",
    smtp_port=587,
    use_tls=True,
    debug=True  # Set to False to actually send the email.
)

# Create and send the email message.
sender.create_message(
    receiver="[e-mail]",
    subject="Hello from SMTP-Email-Sender"
).attach(
    email_text("This is a test email sent using SMTP-Email-Sender!", "plain")
).sendmail()

# Finalize and close the SMTP connection.
sender.finish()

2. Sending Emails Using a Template

Send personalized emails to multiple recipients with dynamic content:

from smtp_email_sender import EmailSender

# Initialize the EmailSender.
sender = EmailSender(
    sender="[e-mail]",
    password="your_password",
    smtp_server="smtp.example.com",
    smtp_port=587,
    use_tls=True,
    debug=True  # Toggle debug mode as needed.
)

# Define your email template with placeholders.
template = "Hi {name},\n\nWe are excited to invite you to {event}! See you there."

# Define the recipient data.
mails = ["[e-mail]", "[e-mail]"]
subjects = ["Invitation to Python Meetup", "Invitation to Python Meetup"]
placeholders = [
    {"name": "Alice", "event": "the Python Meetup"},
    {"name": "Bob", "event": "the Python Meetup"}
]

# Optionally, define CC lists and file attachments (here, none).

# Send the templated emails.
sender.sendmail_from_template(
    template=template,
    mails=mails,
    subjects=subjects,
    text_type="plain",
    placeholders=placeholders
)

# Finalize the process.
sender.finish()

3. Attaching Files

Attach files to your email with proper encoding:

from smtp_email_sender import EmailSender, email_file, email_text

# Initialize the EmailSender.
sender = EmailSender(
    sender="[e-mail]",
    password="your_password",
    smtp_server="smtp.example.com",
    smtp_port=587,
    use_tls=True,
    debug=True
)

# Create a message and attach both text content and a file.
sender.create_message("[e-mail]", "Monthly Report") \
      .attach(email_text("Please find the monthly report attached.", "plain")) \
      .attach(email_file("path/to/report.pdf", "Monthly_Report.pdf")) \
      .sendmail()

# Close the connection.
sender.finish()

4. Using SMTP-Email-Sender with Gmail

Steps to Use Gmail with SMTP-Email-Sender:

1. Enable 2-Step Verification:
   Sign in to your Google account and enable 2-Step Verification.

2. Generate an App Password:
   After enabling 2-Step Verification, go to the App Passwords section. Select the app (e.g., "Mail") and device (e.g., "Other" and name it "SMTP-Email-Sender") and generate an app password. Save this password securely.

3. Update Your Code:
   Use your full Gmail address as the sender and the generated app password in your code. Here's an example:

from smtp_email_sender import EmailSender, email_text

# Replace these values with your Gmail details.
gmail_address = "[e-mail]"
app_password = "your_generated_app_password"

# Initialize the EmailSender using Gmail's SMTP server.
sender = EmailSender(
    sender=gmail_address,
    password=app_password,
    smtp_server="smtp.gmail.com",
    smtp_port=587,
    use_tls=True,
    debug=True  # Set to False to send the email for real.
)

# Create and send the email message.
sender.create_message(
    receiver="[e-mail]",
    subject="Hello from SMTP-Email-Sender via Gmail"
).attach(
    email_text("This email was sent using Gmail's SMTP server and an App Password.", "plain")
).sendmail()

# Finalize and close the SMTP connection.
sender.finish()

Follow these steps to securely send emails via Gmail using SMTP-Email-Sender.

Logging & Debugging

SMTP-Email-Sender uses Python's built-in logging module to provide detailed feedback. When in debug mode (debug=True), the module logs the recipients, email content, and any errors without actually sending emails—ideal for development and testing.

Check your console or log files to see these detailed messages, which can help diagnose issues with SMTP connection, authentication, or file attachments.
