Editor to share with you how python group emails, I believe that most people do not know much, so share this article for your reference, I hope you will learn a lot after reading this article, let's go to know it!

Python group email mainly depends on the STMP module, but many novices don't know it. Let's let the one-meter software tell you.

SMTP (Simple Mail Transfer Protocol), or simple Mail transfer Protocol, is a set of rules for sending messages from source to destination, which controls the way letters are transferred. Python's smtplib provides a convenient way to send e-mail. It simply encapsulates the smtp protocol.

Group email attachment:

The basic idea is to use MIMEMultipart to indicate that the message is made up of multiple parts, and then attach each part. If it is an attachment, add_header adds the declaration of the attachment.

In python, the inheritance of these objects for MIME is as follows.

MIMEBase

|-- MIMENonMultipart

|-- MIMEApplication

|-- MIMEAudio

|-- MIMEImage

|-- MIMEMessage

|-- MIMEText

|-- MIMEMultipart

In general, MIMEBase is not used, but its inherited class is used directly. MIMEMultipart has an attach method, while MIMENonMultipart does not, and can only be attach.

There are many types of MIME, this is a little troublesome, if the attachment is a picture format, I want to use MIMEImage, if it is audio, to use MIMEAudio, if it is word, excel, I do not know which type of MIME should be used, I have to go to google to check.

The laziest way is to use MIMEApplication for any type of attachment, and the MIMEApplication default subtype is application/octet-stream.
