The SocketLabs Email Delivery Python library allows you to easily send email messages via the SocketLabs Injection API. The library makes it easy to build and send any type of message supported by the API, from a simple message to a single recipient all the way to a complex bulk message sent to a group of recipients with unique merge data per recipient.

Installation
pip
pip install socketlabs-injectionapi
From a local archive using pip
You can just download the package and install from a local archive file.
pip install <path>/socketlabs_injectionapi-1.4.0.tar.gz

pip install git+https://github.com/socketlabs/socketlabs-python.git#egg=socketlabs_injectionapi
For more information please see the Installing Packages tutorial
Getting Started
Obtaining your API Key and SocketLabs ServerId number
In order to get started, you'll need to enable the Injection API feature in the SocketLabs Control Panel. Once logged in, navigate to your SocketLabs server's dashboard (if you only have one server on your account you'll be taken here immediately after logging in). Make note of your 4 or 5 digit ServerId number, as you'll need this along with your API key in order to use the Injection API.
To enable the Injection API, click on the "For Developers" dropdown on the top-level navigation, then choose the "Configure HTTP Injection API" option. Once here, you can enable the feature by choosing the "Enabled" option in the dropdown. Enabling the feature will also generate your API key, which you'll need (along with your ServerId) to start using the API. Be sure to click the "Update" button to save your changes once you are finished.
Basic Message
A basic message is an email message like you'd send from a personal email client such as Outlook. A basic message can have many recipients, including multiple To addresses, CC addresses, and even BCC addresses. You can also send a file attachment in a basic message.
from socketlabs.injectionapi import SocketLabsClient
from socketlabs.injectionapi.message.basicmessage import BasicMessage
from socketlabs.injectionapi.message.emailaddress import EmailAddress
# Your SocketLabs ServerId and Injection API key
client = SocketLabsClient(10000, "YOUR-API-KEY");
message = BasicMessage()
message.subject = "Sending A BasicMessage"
message.html_body = "<html>This is the Html Body of my message.</html>"
message.plain_text_body = "This is the Plain Text Body of my message.";
message.from_email_address = EmailAddress("from@example.com")
# A basic message supports up to 50 recipients
# and supports several different ways to add recipients
# Add a To address by passing the email address
message.to_email_address.append(EmailAddress("recipient1@example.com"))
message.to_email_address.append(EmailAddress("recipient2@example.com", "Recipient #2"))
# // Adding CC Recipients
message.add_cc_email_address("recipient3@example.com")
message.add_cc_email_address("recipient4@example.com", "Recipient #4")
# Adding Bcc Recipients
message.add_bcc_email_address(EmailAddress("recipient5@example.com"))
message.add_bcc_email_address(EmailAddress("recipient6@example.com", "Recipient #6"))
response = client.send(message)Bulk Message
A bulk message usually contains a single recipient per message and is generally used to send the same content to many recipients, optionally customizing the message via the use of MergeData. For more information about using Merge data, please see the Injection API documentation.
from socketlabs.injectionapi import SocketLabsClient
from socketlabs.injectionapi.message.bulkmessage import BulkMessage
from socketlabs.injectionapi.message.bulkrecipient import BulkRecipient
from socketlabs.injectionapi.message.emailaddress import EmailAddress
# Your SocketLabs ServerId and Injection API key
client = SocketLabsClient(10000, "YOUR-API-KEY");
message = BulkMessage()
message.plain_text_body = "This is the body of my message sent to %%Name%%"
message.html_body = "<html>This is the HtmlBody of my message sent to %%Name%%</html>"
message.subject = "Sending a test message"
message.from_email_address = EmailAddress("from@example.com")
recipient1 = BulkRecipient("recipient1@example.com")
recipient1.add_merge_data("Name", "Recipient1")
message.add_to_recipient(recipient1)
recipient2 = BulkRecipient("recipient2@example.com", "Recipient #2")
recipient2.add_merge_data("Name", "Recipient2")
message.add_to_recipient(recipient2)
response = client.send(message)Managing API Keys
For ease of demonstration, many of our examples include the ServerId (SOCKETLABS_SERVER_ID) and API key (SOCKETLABS_INJECTION_API_KEY) directly in our code sample. Generally it is not considered a good practice to store sensitive information like this directly in your code. Depending on your project type, we recommend either storing your credentials using Environment Variables. For more information please see: Using Environment Variables
Examples and Use Cases
In order to demonstrate the many possible use cases for the SDK, we've provided an assortment of code examples. These examples demonstrate many different features available to the Injection API and SDK, including using templates created in the SocketLabs Email Designer, custom email headers, sending attachments, sending content that is stored in an HTML file, advanced bulk merging, and even pulling recipients from a datasource.
Basic send from SocketLabs Template
This example demonstrates the sending of a piece of content that was created in the SocketLabs Email Designer. This is also known as the API Templates feature.
Basic send from HTML file
This example demonstrates how to read in your HTML content from an HTML file rather than passing in a string directly.
Basic send with file attachment
This example demonstrates how to add a file attachment to your message.
Basic send with embedded image
This example demonstrates how to embed an image in your message.
Basic send with specified character set
This example demonstrates sending with a specific character set.
Basic send with custom email headers
This example demonstrates how to add custom headers to your email message.
Basic send with a web proxy
This example demonstrates how to use a proxy with your HTTP client.
Basic send with retry enabled
This example demonstrates how to use the retry logic with your HTTP client.
Basic send async example
Basic send async example
Basic send complex example
