Masonite comes with email support out of the box. Most projects you make will need to send emails upon actions like account creation or notifications. Because email is used so often with software applications, masonite provides mail support with several drivers.

Getting Started

All mail configuration is inside config/ and contains several well documented options. There are several built in drivers you can use but you can make your own if you'd like.

You can follow the documentation here at Creating a Mail Driver. If you do make your own, consider making it available on PyPi so others can install it. We may even put it in Masonite by default.

By default, Masonite uses the smtp driver. Inside your .env file, just put your smtp credentials. If you are using Mailgun then switch your driver to mailgun and put your Mailgun credentials in your .env file.

Configuring Drivers

There are two drivers out of the box that masonite uses and there is a tiny bit of configuration for both.

SMTP Driver

The SMTP driver takes several configuration files we can all put in our .env file.


Because this is SMTP, we can utilize all SMTP services such as mailtrap and gmail.

Thats it! As long as the authentication works, we can send emails.

Remember that it is save to put sensitive data in your .env file because it is not committed to source control and it is inside the .gitignore file by default.

Mailgun Driver

Mailgun does not use SMTP and instead uses API calls to their service to send emails. Mailgun only requires 2 configuration settings:


If you change to using Mailgun then you will need to change the driver. By default the driver looks like:

DRIVER = os.getenv('MAIL_DRIVER', 'smtp')

This means you can specify the mail driver in the .env file:


or we can specify the driver directly inside config/

DRIVER = 'mailgun'

Masonite will retrieve the configuration settings for the mailgun driver from the DRIVERS configuration setting which Masonite has by default, you do not have to change this.

    'mailgun': {
        'secret': os.getenv('MAILGUN_SECRET', 'key-XX'),
        'domain': os.getenv('MAILGUN_DOMAIN', '')

Sending an Email

The Mail class is loaded into the container via the the MailProvider Service Provider. We can fetch this Mail class via our controller methods:

def show(self, Mail):
    print(Mail) # returns the default mail driver

We can send an email like so:

def show(self, Mail):'').send('Welcome!')

You can also obviously specify a specific user:

from app.User import User
def show(self, Mail):'Welcome!')

Switching Drivers

All mail drivers are managed by the MailManager class and bootstrapped with the MailProvider Service Provider.

We can specify which driver we want to use. Although Masonite will use the DRIVER variable in our mail config file by default, we can change the driver on the fly.

You can see in our MailProvider Service Provider that we can use the MailManager class to set the driver. We can use this same class to change the driver:

def show(self, MailManager):
    MailManager.driver('mailgun') # now uses the Mailgun driver


Sending an email may take several seconds so it might be a good idea to create a Job. Jobs are simply Python classes that inherit from the Queueable class and can be pushed to queues or ran asynchronously. This will look something like:

from import SendWelcomeEmail

def show(self, Queue):

Instead of taking seconds to send an email, this will seem immediate and be sent using whatever queue driver is set. The async driver is set by default which requires no additional configuration and simply sends jobs into a new thread to be ran in the background.

Read more about creating Jobs and sending emails asynchronously in the Queues and Jobs documentation.


We can also specify the subject:


You can specify which address you want the email to appear from:



If you don't want to pass a string as the message, you can pass a view template.'').template('mail/welcome').send()

This will render the view into a message body and send the email as html. Notice that we didn't pass anything into the send message
