1. Preparation
Before we start, we need to prepare some things. First, we need to install Python. Python can be downloaded from the official website.
Secondly, we need to install the smtplib library. This can be done in the terminal with the following command:
pip install smtplib
2. Create the email
Before sending the email, we need to create the email. For this, we need to use Python’s email library.
This library allows us to create various types of emails, including HTML formatted emails.
The following is a simple Python program for creating an email in HTML format:
import smtplib from email.mime.multipart import MIMEMultipart from email.mime.text import MIMEText # 创建一个带有HTML正文的新电子邮件 msg = MIMEMultipart() msg['From'] = 'sender@example.com' msg['To'] = 'receiver@example.com' msg['Subject'] = 'HTML邮件' # HTML正文 html = """ <html> <body> <h2>这是一个HTML邮件</h2> <p>这是一个演示如何发送HTML格式电子邮件的示例。</p > </body> </html> """ # 将HTML正文添加到电子邮件中 msg.attach(MIMEText(html, 'html')) # 使用SMTP服务器发送电子邮件 server = smtplib.SMTP('smtp.gmail.com', 587) server.starttls() server.login('sender@example.com', 'password') server.sendmail('sender@example.com', 'receiver@example.com', msg.as_string()) server.quit()
In this example, we first introduce the necessary Modules: smtplib, MIMEMultipart and MIMEText.
Next, we create a MIMEMultipart instance and set some email headers. The next step is to build an HTML body and then add it to the email using MIMEText.
Finally, we use the SMTP server to send the email.
3. Send an email
After we create the email, we need to send it using an SMTP server.
SMTP server is a protocol used to send email. In Python, you can use the smtplib module to send emails.
The following is a simple Python program for sending an email in HTML format:
import smtplib from email.mime.multipart import MIMEMultipart from email.mime.text import MIMEText # 创建一个带有HTML正文的新电子邮件 msg = MIMEMultipart() msg['From'] = 'sender@example.com' msg['To'] = 'receiver@example.com' msg['Subject'] = 'HTML邮件' # HTML正文 html = """ <html> <body> <h2>这是一个HTML邮件</h2> <p>这是一个演示如何发送HTML格式电子邮件的示例。</p > </body> </html> """ # 将HTML正文添加到电子邮件中 msg.attach(MIMEText(html, 'html')) # 使用SMTP服务器发送电子邮件 server = smtplib.SMTP('smtp.gmail.com', 587) server.starttls() server.login('sender@example.com', 'password') server.sendmail('sender@example.com', 'receiver@example.com', msg.as_string()) server.quit()
In this example, we first create a new MIMEMultipart object and set some email headers.
Next, we generate an HTML body and add it to the email using MIMEText. Finally, we use an SMTP server to send emails.
4. Add attachments
In addition to the HTML body, we can also add attachments to the email. For this, we need to use Python’s email library.
The following is a simple Python program for adding attachments to HTML-formatted emails:
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.image import MIMEImage
# 创建一个带有HTML正文和图片附件的新电子邮件
msg = MIMEMultipart()
msg['From'] = 'sender@example.com'
msg['To'] = 'receiver@example.com'
msg['Subject'] = 'HTML邮件'
# HTML正文
html = """
<html>
<body>
<h2>这是一个HTML邮件</h2>
<p>这是一个演示如何发送HTML格式电子邮件的示例。</p >
<p>下面是一张图片：</p >
< img src="cid:image1">
</body>
</html>
"""
# 将HTML正文添加到电子邮件中
msg.attach(MIMEText(html, 'html'))
# 添加图片附件
with open('image.png', 'rb') as f:
img_data = f.read()
img = MIMEImage(img_data)
img.add_header('Content-ID', '<image1>')
msg.attach(img)
# 使用SMTP服务器发送电子邮件
server = smtplib.SMTP('smtp.gmail.com', 587)
server.starttls()
server.login('sender@example.com', 'password')
server.sendmail('sender@example.com', 'receiver@example.com', msg.as_string())
server.quit()In this example, we first create a new MIMEMultipart object and set Some email headers.
Next, we will create an HTML body and attach it to the email using MIMEText. Next, we add an image attachment using MIMEImage and link it to the HTML body using Content-ID.
Finally, we use the SMTP server to send the email.
