The flask-emails extension is a simple way to send email messages from Flask application. It is a wrapper for python-emails.
- Email message abstraction with html and text part, with inline attachments, etc.
- Email body template rendering
- Email HTML body transform methods: css inlining, image inlining, etc.
- SMTP backends
- DKIM signature
- Configured via Flask application config
Note
There are another flask extension Flask-Mail which solves almost same problems. I guess flask-emails solves little more problems.
Add email-specific options to your flask application, for example:
from flask import Flask
app = Flask(__name__)
app.config = {'EMAIL_HOST': 'localhost', 'EMAIL_PORT': 25, 'EMAIL_TIMEOUT': 10}Create and send email:
from flask_emails import Message
message = Message(html='<html><p>Hi! ...',
subject="Party today",
mail_from=("John Brown", "john@gmail.com"))
message.attach(data=open('Event.ics', 'rb'), filename='Event.ics')
r = message.send(to=("Nick Jackson", "nick@gmail.com"))
if r.status_code not in [250, ]:
# message is not sent, deal with this
...See more examples on python-emails docs
By default flask-emails reads configuration from current Flask application config when you first time create :meth:`~Message` object.
It reads the following variables:
