SendGrid-Python

This library allows you to quickly and easily send emails through SendGrid using Python.

https://travis-ci.org/sendgrid/sendgrid-python.svg?branch=master

Warning

If you upgrade to version 1.2.x, the add_to method behaves differently. In the past this method defaulted to using the SMTPAPI header. Now you must explicitly call the smtpapi.add_to method. More on the SMTPAPI section.

Install

pip install sendgrid
# or
easy_install sendgrid

Example

import sendgrid

sg = sendgrid.SendGridClient('YOUR_SENDGRID_USERNAME', 'YOUR_SENDGRID_PASSWORD')

message = sendgrid.Mail()
message.add_to('John Doe <john@email.com>')
message.set_subject('Example')
message.set_html('Body')
message.set_text('Body')
message.set_from('Doe John <doe@email.com>')
status, msg = sg.send(message)

#or

message = sendgrid.Mail(to='john@email.com', subject='Example', html='Body', text='Body', from_email='doe@email.com')
status, msg = sg.send(message)

Error handling

By default, .send method returns a tuple (http_status_code, message), however you can pass raise_errors=True to SendGridClient constructor, then .send method will raise SendGridClientError for 4xx errors, and SendGridServerError for 5xx errors.

from sendgrid import SendGridError, SendGridClientError, SendGridServerError

sg = sendgrid.SendGridClient(username, password, raise_errors=True)

try:
    sg.send(message)
except SendGridClientError:
    ...
except SendGridServerError:
    ...

This behavior is going to be default from version 2.0.0. You are encouraged to set raise_errors to True for forwards compatibility.

SendGridError is a base-class for all SendGrid-related exceptions.

Usage

To begin using this library create a new instance of SendGridClient with your SendGrid credentials or a SendGrid API Key. API Key is the preferred method. API Keys are in beta. To configure API keys, visit https://sendgrid.com/beta/settings/api_key.

sg = sendgrid.SendGridClient('sendgrid_username', 'sendgrid_password')
# or
sg = sendgrid.SendGridClient('sendgrid_apikey')

Methods

There are multiple ways to add recipients:

add_to

message = sendgrid.Mail()
message.add_to('example@email.com')
# or
message.add_to('Example Dude <example@email.com>')
# or
message.add_to(['Example Dude <example@email.com>', 'john@email.com'])

add_to_name

message = sendgrid.Mail()
message.add_to('example@email.com')
message.add_to_name('Example Dude')

add_cc

message = sendgrid.Mail()
message.add_cc('example@email.com')
message.add_cc(['example@email.com', 'john@email.com'])

add_bcc

message = sendgrid.Mail()
message.add_bcc('example@email.com')
# or
message.add_bcc(['Example Dude <example@email.com>', 'john@email.com'])

set_from

message = sendgrid.Mail()
message.set_from('example@email.com')

set_from_name

message = sendgrid.Mail()
message.set_from('example@email.com')
message.set_from_name('Example Dude')

set_replyto

message.sendgrid.Mail()
message.set_replyto('example@email.com')

set_subject

message = sendgrid.Mail()
message.set_subject('Example')

set_text

message = sendgrid.Mail()
message.set_text('Body')

set_html

message = sendgrid.Mail()
message.set_html('<html><body>Stuff, you know?</body></html>')

set_date

message = sendgrid.Mail()
message.set_date('Wed, 17 Dec 2014 19:21:16 +0000')

set_headers

message = sendgrid.Mail()
message.set_headers({'X-Sent-Using': 'SendGrid-API', 'X-Transport': 'web'});

Set File Attachments

There are multiple ways to work with attachments:

add_attachment

message = sendgrid.Mail()
message.add_attachment('stuff.txt', './stuff.txt')
# or
message.add_attachment('stuff.txt', open('./stuff.txt', 'rb'))

add_attachment_stream

message = sendgrid.Mail()
message.add_attachment_stream('filename', 'somerandomcontentyouwant')
# strings, unicode, or BytesIO streams

add_content_id

message = sendgrid.Mail()
message.add_attachment('image.png', open('./image.png', 'rb'))
message.add_content_id('image.png', 'ID_IN_HTML')
message.set_html('<html><body>TEXT BEFORE IMAGE<img src="cid:ID_IN_HTML"></img>AFTER IMAGE</body></html>')

SendGrid's X-SMTPAPI

If you wish to use the X-SMTPAPI on your own app, you can use the SMTPAPI Python library.

There are implementations for setter methods too.

Recipients

message = sendgrid.Mail()
message.smtpapi.add_to('example@email.com')

Substitution

message = sendgrid.Mail()
message.smtpapi.add_substitution('key', 'value')

add_substitution

message = sendgrid.Mail()
message.add_substitution('key', 'value')

set_substitutions

message = sendgrid.Mail()
message.set_substitutions({'key1': ['value1', 'value2'], 'key2': ['value3', 'value4']})

Section

message = sendgrid.Mail()
message.smtpapi.add_section('section', 'value')

add_section

message = sendgrid.Mail()
message.add_section('section', 'value')

set_sections

message = sendgrid.Mail()
message.set_sections({'section1': 'value1', 'section2': 'value2'})

Category

message = sendgrid.Mail()
message.smtpapi.add_category('category')

add_category

message = sendgrid.Mail()
message.add_category('category')

set_categories

message = sendgrid.Mail()
message.set_categories(['category1', 'category2'])

Unique Arguments

message = sendgrid.Mail()
message.smtpapi.add_unique_arg('key', 'value')

add_unique_arg

message = sendgrid.Mail()
message.add_unique_arg('key', 'value')

set_unique_args

message = sendgrid.Mail()
message.set_unique_args({'key1': 'value1', 'key2': 'value2'})

Filter

message = sendgrid.Mail()
message.smtpapi.add_filter('filter', 'setting', 'value')

add_filter

message = sendgrid.Mail()
message.add_filter('filter', 'setting', 'value')

ASM Group

message = sendgrid.Mail()
message.smtpapi.set_asm_group_id(value)

set_asm_group_id

message = sendgrid.Mail()
message.set_asm_group_id(value)

Using Templates from the Template Engine

message.add_filter('templates', 'enable', '1')
message.add_filter('templates', 'template_id', 'TEMPLATE-ALPHA-NUMERIC-ID')
