Ques 6. How to add an emailing function in Flask?

Yes, we can add an emailing function in the Flask framework. Actually, we need to install the Flask-Mail extension. We can use the given below command:

Pip install Flask-Mail 

Now, after installation, we need to go to the Flask Config API. Under config, we will get Mail-Server, Mail_Port, Mail_username, Mail_Password, etc options. We can use the mail.send() method to compose the message.

from flask_mail import Mail,Message 
from flask import Flaskapp=Flask(_name_)
mail=Mail(app)
@app.route(\"/mail\")
def email():
Msg=Message(\"Hello Message\",Sender=\"admin@test.com\",recipients=[\"to@test.com\"])
Mail.send(msg)
