hi I've been following you for a while now and your videos are very helpful! I have a question though. Let's say I want to build an app that let users to type in their emails and password and send an email using that account entered. is it possible to instantiate the config during runtime? or like while the app is running?

[@simplepycodes]

awesome tutorial. my question is that when you develop Flask web app, is it a must to use flask mail for Mailing functions? why not just use, lets say smtplib? Thanks a lot.

[@prettyprinted]

You can use the library itself, but Flask-Mail just fits the Flask pattern a little better.

@@prettyprinted Thank you

Thank you for this video sir.. Can you please tell me..how to send bulk mail in this!

[@prettyprinted]

Here's how to send bulk emails: pythonhosted.org/Flask-Mail/#bulk-emails

[@rajagopalxyz]

First of all, Thanks a lot for wonderful tutorials. :) I have two questions on emails. a) Can I have multiple email backend settings ? As far as I saw only one email setting could be configured. b) Is there any way to dynamically change or choose email setting during runtime ?

[@prettyprinted]

You could, but it's hard to explain. I'll make a video on this eventually.

Hi, Greate tutorial btw. I am using flask-mail and the following config : app.config['MAIL_SERVER']='smtp.office365.com' app.config['MAIL_PORT'] = 587 app.config['MAIL_USE_TLS'] = True app.config['MAIL_USE_SSL'] = False when I run my app locally I am able to receive the message but when I use Heroku I receive a winmail.dat file do you have any idea how to fix this issue? thanks

I am using university proxy, what additional code needs to be written, for it to work

[@ishanichakravorty9275]

hey! thank you so much for making this video! i just wanted to ask what does if __name__ == 'main: app.run(debug=True) do?thanks!

[@prettyprinted]

It starts the server if you execute the file from the command line. If you include the file within any module, the server won't start.

[@ishanichakravorty9275]

Pretty Printed thank you

Hi Anthony! How are you doing? Look, I've followed this lesson and successfully managed to send a email via Flask-Mail. The problem is that when the email arrives in my inbox, it comes from the email that I provided via config (along with the password), and not from the sender email (provided when creating the message). Do you know how to send from sender? Thanks!

[@prettyprinted]

I'm doing well, thanks, Try the MAIL_DEFAULT_SENDER config value. Just beware that if the email account domain and sender domain are different, you'll likely trigger anti-spam functionality in the receiver's email inbox. Thanks for watching!

[@TheNetoCampos]

I'll try that. Thanks for the answer and keep the good work.

[@Glauberz1]

hello,whats written in the config.cfg file?could you post here because i am having trouble trying send email,i tried in a lot of ways but not worked.

[@prettyprinted]

My configuration file has my email information in it, so I don't want to show it. You'll have to play around with the port settings and SSL/TLS settings until you find the right combination.

[@chrisc.4144]

This was great. Thank you !

[@prettyprinted]

Thanks for watching! (I'm just now seeing your comment).

Does Flask-mail only work for sending messaging messages? I want to receive messages. This only works if I put my email address as the sender but I want to be the recipient and I other people to send a messages to me through a contact form. How do I do that instead? I tried switching my email address as the recipient but I got an error....

[@prettyprinted]

You can only send emails. For receiving emails, you just use your regular email client.

[@djuka8121]

Why do you need a sender if you defined it with app.config.from_pyfile('config.cfg') and inside that file is 'EMAIL_USERNAME' = 'email' and 'EMAIL_PASSWORD' = 'pass' #note that email and pass are examples

error 11003 .... socket.gaierror ... how to solve plz reply

[@prettyprinted]

It probably means the host you provided for your email is incorrect.

Always hitting this error when trying to use the Flask-Mail module: > (venv) pi@raspberrypi:/var/www/flaskapp $ python manage.py shell > ImportError: No module named flask.ext.mail Yet in my main.py: > from flask_mail import Mail, Message Yet in pip install FLask-Mail : > (venv) pi@raspberrypi:/var/www/flaskapp $ sudo pip install Flask-Mail > Requirement already satisfied (use --upgrade to upgrade): Flask-Mail in /usr/local/lib/python2.7/dist-packages Try to look on internet, but is rather not clear to me what is going wrong. If you could assist? Many thanks in advance?

[@wimrotor]

Just found out that I need to run everything with "root" permissions: > sudo pip install Flask-Mail==0.9.1 > Successfully installed Flask-Mail > (venv) pi@raspberrypi:/var/www/flaskapp $ sudo pip freeze | grep "ail" > Flask-Mail==0.9.1 > (venv) pi@raspberrypi:/var/www/flaskapp $ python manage.py shell > File "/var/www/flaskapp/main.py", line 5, in > from flask_mail import Mail, Message >ImportError: No module named flask_mail BUT: (venv) pi@raspberrypi:/var/www/flaskapp $ sudo python manage.py shell >>> Is working ... ! :)

[@prettyprinted]

I'm glad you figured it out. Thanks for watching!

[@marcelgiglio]

but there is no diferentiation between body and subject? this recipients, its cc or cco?

How can we send attachment in the email?

[@yolomein415]

how come you dont need a password, is it possible that i send from someone else's email!?

[@prettyprinted]

I do use a password. You just don't see it in the video. It's in the config.cfg file.

[@yolomein415]

Pretty Printed so in the config file, do you just have a plaintext password or is it like password=“the_password”?

[@prettyprinted]

@@yolomein415 You can use quotes in the config file. So just password='the_password'

[@yolomein415]

Pretty Printed thanks 🙏 i get it now!!!

[@alejandrombc]
