How do I set up Flask-Mail in my Flask application?

To set up Flask-Mail, first install it using pip: pip install Flask-Mail. Then, configure it in your app.

What configurations do I need to add for SMTP?

You need to set the MAIL_SERVER, MAIL_PORT, MAIL_USERNAME, MAIL_PASSWORD, and MAIL_USE_TLS or MAIL_USE_SSL in your app's config.

Can you show me a code example for sending an email?

Sure! Here's a simple example:

from flask import Flask
from flask_mail import Mail, Message

app = Flask(__name__)
app.config['MAIL_SERVER'] = 'smtp.example.com'
app.config['MAIL_PORT'] = 587
app.config['MAIL_USERNAME'] = '[email protected]'
app.config['MAIL_PASSWORD'] = 'your_password'
app.config['MAIL_USE_TLS'] = True

mail = Mail(app)

@app.route('/send_email/')
def send_email():
    msg = Message('Hello', sender='[email protected]', recipients=['[email protected]'])
    msg.body = 'This is a test email.'
    mail.send(msg)
    return 'Email sent!'

Make sure to replace the placeholders with your actual email details.

What if I want to send HTML emails?

You can set the msg.html attribute to include HTML content. For example:

msg.html = '<h1>This is an HTML email</h1>'
