从Python v2.7.14文档- 18.1.11。电子邮件:例子:

下面是如何创建一个纯文本版本的HTML消息的示例:

#! /usr/bin/python


import smtplib


from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText


# me == my email address
# you == recipient's email address
me = "my@email.com"
you = "your@email.com"


# Create message container - the correct MIME type is multipart/alternative.
msg = MIMEMultipart('alternative')
msg['Subject'] = "Link"
msg['From'] = me
msg['To'] = you


# Create the body of the message (a plain-text and an HTML version).
text = "Hi!\nHow are you?\nHere is the link you wanted:\nhttp://www.python.org"
html = """\
<html>
<head></head>
<body>
<p>Hi!<br>
How are you?<br>
Here is the <a href="http://www.python.org">link</a> you wanted.
</p>
</body>
</html>
"""


# Record the MIME types of both parts - text/plain and text/html.
part1 = MIMEText(text, 'plain')
part2 = MIMEText(html, 'html')


# Attach parts into message container.
# According to RFC 2046, the last part of a multipart message, in this case
# the HTML message, is best and preferred.
msg.attach(part1)
msg.attach(part2)


# Send the message via local SMTP server.
s = smtplib.SMTP('localhost')
# sendmail function takes 3 arguments: sender's address, recipient's address
# and message to send - here it is sent as one string.
s.sendmail(me, you, msg.as_string())
s.quit()

下面是示例代码。这个灵感来自Python食谱站点上的代码(找不到确切的链接)

def createhtmlmail (html, text, subject, fromEmail):
"""Create a mime-message that will render HTML in popular
MUAs, text in better ones"""
import MimeWriter
import mimetools
import cStringIO


out = cStringIO.StringIO() # output buffer for our message
htmlin = cStringIO.StringIO(html)
txtin = cStringIO.StringIO(text)


writer = MimeWriter.MimeWriter(out)
#
# set up some basic headers... we put subject here
# because smtplib.sendmail expects it to be in the
# message body
#
writer.addheader("From", fromEmail)
writer.addheader("Subject", subject)
writer.addheader("MIME-Version", "1.0")
#
# start the multipart section of the message
# multipart/alternative seems to work better
# on some MUAs than multipart/mixed
#
writer.startmultipartbody("alternative")
writer.flushheaders()
#
# the plain text section
#
subpart = writer.nextpart()
subpart.addheader("Content-Transfer-Encoding", "quoted-printable")
pout = subpart.startbody("text/plain", [("charset", 'us-ascii')])
mimetools.encode(txtin, pout, 'quoted-printable')
txtin.close()
#
# start the html subpart of the message
#
subpart = writer.nextpart()
subpart.addheader("Content-Transfer-Encoding", "quoted-printable")
#
# returns us a file-ish object we can write to
#
pout = subpart.startbody("text/html", [("charset", 'us-ascii')])
mimetools.encode(htmlin, pout, 'quoted-printable')
htmlin.close()
#
# Now that we're done, close our writer and
# return the message body
#
writer.lastpart()
msg = out.getvalue()
out.close()
print msg
return msg

你可以尝试使用我的梅勒模块。

from mailer import Mailer
from mailer import Message


message = Message(From="me@example.com",
To="you@example.com")
message.Subject = "An HTML Email"
message.Html = """<p>Hi!<br>
How are you?<br>
Here is the <a href="http://www.python.org">link</a> you wanted.</p>"""


sender = Mailer('smtp.example.com')
sender.send(message)

下面是接受答案的Gmail实现:

import smtplib


from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText


# me == my email address
# you == recipient's email address
me = "my@email.com"
you = "your@email.com"


# Create message container - the correct MIME type is multipart/alternative.
msg = MIMEMultipart('alternative')
msg['Subject'] = "Link"
msg['From'] = me
msg['To'] = you


# Create the body of the message (a plain-text and an HTML version).
text = "Hi!\nHow are you?\nHere is the link you wanted:\nhttp://www.python.org"
html = """\
<html>
<head></head>
<body>
<p>Hi!<br>
How are you?<br>
Here is the <a href="http://www.python.org">link</a> you wanted.
</p>
</body>
</html>
"""


# Record the MIME types of both parts - text/plain and text/html.
part1 = MIMEText(text, 'plain')
part2 = MIMEText(html, 'html')


# Attach parts into message container.
# According to RFC 2046, the last part of a multipart message, in this case
# the HTML message, is best and preferred.
msg.attach(part1)
msg.attach(part2)
# Send the message via local SMTP server.
mail = smtplib.SMTP('smtp.gmail.com', 587)


mail.ehlo()


mail.starttls()


mail.login('userName', 'password')
mail.sendmail(me, you, msg.as_string())
mail.quit()

下面是发送HTML电子邮件的简单方法，只需指定Content-Type头为'text/ HTML ':

import email.message
import smtplib


msg = email.message.Message()
msg['Subject'] = 'foo'
msg['From'] = 'sender@test.com'
msg['To'] = 'recipient@test.com'
msg.add_header('Content-Type','text/html')
msg.set_payload('Body of <b>message</b>')


# Send the message via local SMTP server.
s = smtplib.SMTP('localhost')
s.starttls()
s.login(email_login,
email_passwd)
s.sendmail(msg['From'], [msg['To']], msg.as_string())
s.quit()

实际上，yagmail采用了一点不同的方法。

它将默认情况下发送HTML，为无能的电子邮件阅读器自动回退。现在已经不是17世纪了。

当然，它可以被覆盖，但如下所示:

import yagmail
yag = yagmail.SMTP("me@example.com", "mypassword")


html_msg = """<p>Hi!<br>
How are you?<br>
Here is the <a href="http://www.python.org">link</a> you wanted.</p>"""


yag.send("to@example.com", "the subject", html_msg)

以下是我对AWS使用boto3的回答

    subject = "Hello"
html = "<b>Hello Consumer</b>"


client = boto3.client('ses', region_name='us-east-1', aws_access_key_id="your_key",
aws_secret_access_key="your_secret")


client.send_email(
Source='ACME <do-not-reply@acme.com>',
Destination={'ToAddresses': [email]},
Message={
'Subject': {'Data': subject},
'Body': {
'Html': {'Data': html}
}
}

下面是一个工作示例，使用smtplib以及CC和BCC选项从Python发送纯文本和HTML电子邮件。

https://varunver.wordpress.com/2017/01/26/python-smtplib-send-plaintext-and-html-emails/

#!/usr/bin/env python
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText


def send_mail(params, type_):
email_subject = params['email_subject']
email_from = "from_email@domain.com"
email_to = params['email_to']
email_cc = params.get('email_cc')
email_bcc = params.get('email_bcc')
email_body = params['email_body']


msg = MIMEMultipart('alternative')
msg['To'] = email_to
msg['CC'] = email_cc
msg['Subject'] = email_subject
mt_html = MIMEText(email_body, type_)
msg.attach(mt_html)


server = smtplib.SMTP('YOUR_MAIL_SERVER.DOMAIN.COM')
server.set_debuglevel(1)
toaddrs = [email_to] + [email_cc] + [email_bcc]
server.sendmail(email_from, toaddrs, msg.as_string())
server.quit()


# Calling the mailer functions
params = {
'email_to': 'to_email@domain.com',
'email_cc': 'cc_email@domain.com',
'email_bcc': 'bcc_email@domain.com',
'email_subject': 'Test message from python library',
'email_body': '<h1>Hello World</h1>'
}
for t in ['plain', 'html']:
send_mail(params, t)

从Office 365中的组织帐户发送电子邮件的最简单解决方案:

from O365 import Message


html_template =     """
<html>
<head>
<title></title>
</head>
<body>
{}
</body>
</html>
"""


final_html_data = html_template.format(df.to_html(index=False))


o365_auth = ('sender_username@company_email.com','Password')
m = Message(auth=o365_auth)
m.setRecipients('receiver_username@company_email.com')
m.setSubject('Weekly report')
m.setBodyHTML(final_html_data)
m.sendMessage()

这里df是一个转换为html Table的数据帧，它被注入到html_template中

对于python3，改进@taltman的回答:

  • 使用email.message.EmailMessage代替email.message.Message来构造电子邮件。
  • 使用email.set_content func，赋值subtype='html'参数。而不是低级的func set_payload和手动添加头。
  • 使用SMTP.send_message func而不是SMTP.sendmail func发送电子邮件。
  • 使用with块自动关闭连接。
from email.message import EmailMessage
from smtplib import SMTP


# construct email
email = EmailMessage()
email['Subject'] = 'foo'
email['From'] = 'sender@test.com'
email['To'] = 'recipient@test.com'
email.set_content('<font color="red">red color text</font>', subtype='html')


# Send the message via local SMTP server.
with smtplib.SMTP('localhost') as s:
s.login('foo_user', 'bar_password')
s.send_message(email)

我在这里提供答案可能有点晚了，但是这个问题询问了一种发送HTML电子邮件的方法。使用专门的模块，如“电子邮件”;是可以的，但我们可以在不使用任何新模块的情况下实现相同的结果。这都归结为Gmail协议。

下面是我的简单示例代码，仅通过使用“smtplib”发送HTML邮件。没有别的了。

```
import smtplib


FROM = "....@gmail.com"
TO = "another....@gmail.com"
SUBJECT= "Subject"
PWD = "thesecretkey"


TEXT="""
<h1>Hello</h1>
""" #Your Message (Even Supports HTML Directly)


message = f"Subject: {SUBJECT}\nFrom: {FROM}\nTo: {TO}\nContent-Type: text/html\n\n{TEXT}" #This is where the stuff happens


try:
server=smtplib.SMTP("smtp.gmail.com",587)
server.ehlo()
server.starttls()
server.login(FROM,PWD)
server.sendmail(FROM,TO,message)
server.close()
print("Successfully sent the mail.")
except Exception as e:
print("Failed to send the mail..", e)
```

如果你想要更简单的东西:

from redmail import EmailSender
email = EmailSender(host="smtp.myhost.com", port=1)


email.send(
subject="Example email",
sender="me@example.com",
receivers=["you@example.com"],
html="<h1>Hi, this is HTML body</h1>"
)

Pip install Red Mail from PyPI:

pip install redmail

红色邮件几乎有所有你需要从发送电子邮件，它有很多功能，包括:
