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)

对于python3，改进@taltman的回答:

使用email.message. emailmessage而不是email.message. message来构造email。 使用电子邮件。Set_content func, assign 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。 与块一起使用，可自动关闭连接。

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)

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}
        }
    }

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从PyPI安装红色邮件:

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:

附件 模板化(使用Jinja) 嵌入式图像 他们的表 以抄送或密送方式发送 Gmail预配置

文档:https://red-mail.readthedocs.io/en/latest/index.html

源代码:https://github.com/Miksus/red-mail

实际上，yagmail采取了一点不同的方法。

它将在默认情况下发送HTML，并为无法阅读电子邮件的用户提供自动回退功能。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)

有关安装说明和更多伟大的功能，请查看github。

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()
