Send Emails in Django

Sending emails with Amazon SES, Mailgun, Zoho, or Gmail in Django.

Configuration

in settings.py

SERVER_EMAIL = '[email protected]'
DEFAULT_FROM_EMAIL = 'Hourmasters <{0}>'.format(SERVER_EMAIL)
REPLY_TO_EMAIL = '[email protected]'

Amazon SES (Simple Email Service)

1. 在 Amazon SES 上驗證你的 domain
2. 在你的 email 服務商（例如 Google Apps）上建立一個 email 帳號，例如 [email protected]
3. 在 Amazon SES 上驗證這個 email 帳號
4. 收信，點一下確認信裡的超連結
5. 在 Amazon SES 上 Request a Sending Limit Increase

如果你沒有 Request a Sending Limit Increase
預設會是在一個 sandbox 裡面
你只能寄信給你有在 Amazon SES 上驗證過的 email 帳號

$ pip install django-ses

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'email-smtp.us-east-1.amazonaws.com'
EMAIL_HOST_USER = 'YOUR_AWS_ACCESS_KEY_ID'
EMAIL_HOST_PASSWORD = 'YOUR_AWS_SECRET_ACCESS_KEY'
EMAIL_PORT = 587
EMAIL_USE_TLS = True

$ python manage.py ses_email_address -l

Mailgun

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.mailgun.org'
EMAIL_HOST_USER = '[email protected]'
EMAIL_HOST_PASSWORD = 'XXX'
EMAIL_PORT = 587
EMAIL_USE_TLS = True

如果原本就是用 EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
可以無縫改用 https://github.com/pmclanahan/django-celery-email

Zoho

Django 1.7 之前沒有 EMAIL_USE_SSL 這個設定
所以連 zoho 的 mail server 都會 timeout
你可以安裝 django-smtp-ssl

EMAIL_BACKEND = 'django_smtp_ssl.SSLEmailBackend'
EMAIL_HOST = 'smtp.zoho.com'
EMAIL_HOST_USER = '[email protected]'
EMAIL_HOST_PASSWORD = 'XXX'
EMAIL_PORT = 465

Gmail

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_HOST_USER = '[email protected]'  # 也可以是 Google App
EMAIL_HOST_PASSWORD = 'XXX'
EMAIL_PORT = 587
EMAIL_USE_TLS = True

Usage

in views.py

from django.core.mail import EmailMessage
from django.core.mail import send_mail
from django.template.loader import render_to_string

mail_context = {
    'name': 'Vinta',
    'email': '[email protected]',
    'content': 'YOU SUCK',
}
msg = EmailMessage(
    subject='Subject',
    body=render_to_string('email/contact_email.html', mail_context),
    from_email='[email protected]',
    to=['[email protected]', '[email protected]'],
    headers={'Reply-To': settings.REPLY_TO_EMAIL},
)
msg.content_subtype = 'html'  # or 'plain'
msg.send()

# or

send_mail(
    'Subject',
    'Message',
    'YOUR NAME <[email protected]>',
    ['[email protected]', '[email protected]']
)
