Solve UnicodeEncodeError with Python’s SMTPlib Server.Sendmail Function in 10 Words

When it comes to sending emails with Python, the smtplib module can be a great option. However, if you start working with non-ASCII characters, you might encounter the dreaded UnicodeEncodeError. In this post, we’ll explore how to solve this issue using Python’s SMTPlib Server.Sendmail Function in just 10 words.

What is Unicode and UnicodeEncodeError?

Unicode is a character encoding standard that supports a variety of scripts and symbols. It allows us to represent characters from virtually any language in a single encoding system. However, when trying to encode non-ASCII characters using the standard ASCII encoding, we might get a UnicodeEncodeError.

Using the SMTPlib Module in Python

The smtplib module is a built-in Python module that provides a simple way to send email messages using the Simple Mail Transfer Protocol (SMTP). To use it, you’ll first need to create an instance of the SMTP class with the appropriate server settings. Then, you can call the sendmail() method to send your message.

What Causes the UnicodeEncodeError?

The UnicodeEncodeError occurs when Python tries to convert a Unicode string into a byte string. This can happen if you’re trying to send an email that contains non-ASCII characters and you haven’t properly encoded them.

Solution 1: Encode Your Message Before Sending

One solution to the UnicodeEncodeError is to manually encode your message before calling the sendmail() function. This will ensure that all non-ASCII characters are properly encoded using a compatible scheme.

Pros Cons
Simple solution that requires only a few extra lines of code. Requires you to manually encode each message before sending.
Allows you to choose the encoding scheme that fits your message best. Can be cumbersome if you have lots of messages to send or lots of non-ASCII characters.

Solution 2: Use the email Package to Create Your Message

The email package is a built-in Python package that provides a more sophisticated way to create and send email messages. It includes classes for defining headers, attachments, and other message properties. When creating your message using the email package, you can specify the appropriate encoding scheme for each part of your message.

Pros Cons
Gives you more control over the encoding of your message. Requires more advanced knowledge of Python and email protocols.
Allows you to include attachments and other message properties. Can be more time-consuming to set up and debug.

Solution 3: Set the Charset Property of Your Message

Another solution to the UnicodeEncodeError is to set the charset property of your message. This tells the email client how to properly decode your message and eliminates the need for manual encoding. You can set the charset property using the Content-Type header field of your message.

Pros Cons
Eliminates the need for manual encoding of your message. May not be supported by all email clients or servers.
Simple solution that requires only a single line of code. Might still encounter encoding issues if the chosen charset is not properly supported.


Overall, there are several ways to solve the UnicodeEncodeError when using Python’s SMTPlib Server.Sendmail Function. Each solution has its pros and cons and may be more appropriate depending on your specific use case. Whether you choose to manually encode your messages, use the email package, or set the charset property, make sure to test your code thoroughly to ensure that it works as expected.
