Python SMTP email

After creating an SMTP connection in Dashboard, messages can be sent as in the examples below.

Sending plain text e-mails

# -*- coding: utf-8 -*-

# Zato
from zato.common import SMTPMessage
from zato.server.service import Service

class MyService(Service):

    def handle(self):

        # Obtain a connection
        conn = self.email.smtp.get('My Connection').conn

        # Create a regular e-mail
        msg = SMTPMessage()
        msg.subject = 'Hello'
        msg.to = 'hello@example.com'
        msg.from_ = 'howdy@example.com'
        msg.body = 'Hello, how are you?'

        # Send the message
        conn.send(msg)

Sending HTML e-mails

Set is_html to True to signal that the message contains HTML.

# -*- coding: utf-8 -*-

# Zato
from zato.common import SMTPMessage
from zato.server.service import Service

class MyService(Service):

    def handle(self):

        # Obtain a connection
        conn = self.email.smtp.get('My Connection').conn

        # Create a regular e-mail
        msg = SMTPMessage()

        # The flag indicating it is HTML
        msg.is_html = True

        msg.subject = 'Hello'
        msg.to = 'hello@example.com'
        msg.from_ = 'howdy@example.com'
        msg.body = '<b>Hello, how are you?</b>'

        # Send the message
        conn.send(msg)

Sending e-mails with attachments

Provide attachments using the .attach(name, payload) method, as below. This works with both regular and HTML emails although only the former is shown here:

# -*- coding: utf-8 -*-

# Zato
from zato.common import SMTPMessage
from zato.server.service import Service

class MyService(Service):

    def handle(self):

        # Obtain a connection
        conn = self.email.smtp.get('My Connection').conn

        # Create a regular e-mail
        msg = SMTPMessage()
        msg.subject = 'Hello'
        msg.to = 'hello@example.com'
        msg.from_ = 'howdy@example.com'
        msg.body = 'Hello, how are you?'

        # Send attachments along
        msg.attach('attachment_name1.txt', 'Attachment as string goes here')
        msg.attach('attachment_name2.txt', 'Here is another one')

        # Send the message
        conn.send(msg)
