Sending messages

To send a message first create a Message instance:

from flask_mail import Message

@app.route("/")
def index():
    msg = Message("Hello",
                  sender="[email protected]",
                  recipients=["[email protected]"])

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="[email protected]",
              mail_options={'from_name': 'John'},

              cc=["[email protected]"],
