Installation and Setup

To get started, you’ll need to install the Aspose.Email library for Python via .NET. The installation process is straightforward and well-documented, making it accessible to both beginners and experienced developers.

  1. Download the package.

  2. Install the API from PyPI using the following pip command in the console:

> pip install Aspose.Email-for-Python-via-NET

Send Email through Python

To send a message using Python, you need access to an SMTP server. Find the address of the SMTP server on the network, determine the port and the type of encryption, login and authorization method. Some email providers also require you to enable access to the SMTP server in your account settings. Also, if you are not comfortable implementing OAuth authorization in your software, you can try creating a separate password for the application in your account settings.

Use the following option to send a simple text email:

smtpClient = SmtpClient('', 465, 'login', 'password', SecurityOptions.SSL_AUTO)
smtpClient.send('', '', 'subject', 'body')

Send Email with Attachment

The Python API allows sending complex messages using the MailMessage class. It allows you to send messages stored in EML and MSG (Outlook Message Format) file formats. You can also use this format for the following manipulations:

  • Send attachments or iCalendar objects.

  • Set up or confirm attendance.

  • Fine-tune your list of recipients, Cc and Bcc recipients.

  • Send an email with HTML markup.

  • Encrypt the message.

  • Mark the message with various flags before sending it, add metadata, etc.

Consider the code sample for sending a message with an attachment:

# Create a new instance of MailMessage
message = MailMessage('', '', 'Subject', 'Body')

# Add the attachment to the message
attachment = Attachment('path/to/attachment.pdf')

# Send the email
