Configuring Flask-Mail-SendGrid

• MAIL_SENDGRID_API_KEY: API Key for SendGrid

• MAIL_DEFAULT_SENDER: default sender

from flask import Flask
from flask_mail_sendgrid import MailSendGrid

app = Flask(__name__)
app.config['MAIL_SENDGRID_API_KEY'] = 'XXXXXXXX'
mail = MailSendGrid(app)

Sending messages

To send a message first create a Message instance:

from flask_mail import Message

@app.route("/")
def index():
    msg = Message("Hello",
                  sender="from@example.com",
                  recipients=["to@example.com"])

The message can contain a body and/or HTML:

msg.body = "testing"
msg.html = "<b>testing</b>"

Or, if you are using Templates in Sendgrid, you may specify a Template ID and Data:

msg.template_id = 'my-template-id'
msg.dynamic_template_data = {'first_name': 'John', 'last_name': 'Doe'}

Finally, to send the message, you use the Mail instance configured with your Flask application:

mail.send(msg)

Other options

msg = Message("Hello",
              sender="from@example.com",
              mail_options={'from_name': 'John'},
              recipients=["to@example.com"],
              cc=["to@example.com"],
              bcc=["to@example.com"])
