The SocketLabs Email Delivery Python library allows you to easily send any type of email message supported by our Injection API, from a simple message to a single recipient, to a complex bulk message sent to multiple recipients.

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("[email protected]")

# 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("[email protected]"))
message.to_email_address.append(EmailAddress("[email protected]", "Recipient #2"))

# // Adding CC Recipients
message.add_cc_email_address("[email protected]")
message.add_cc_email_address("[email protected]", "Recipient #4")

# Adding Bcc Recipients
message.add_bcc_email_address(EmailAddress("[email protected]"))
message.add_bcc_email_address(EmailAddress("[email protected]", "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.

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 = tests
message.from_email_address = EmailAddress("[email protected]")

recipient1 = BulkRecipient("[email protected]")
recipient1.add_merge_data("Name", "Recipient1")
message.add_to_recipient(recipient1)

recipient2 = BulkRecipient("[email protected]", "Recipient #2")
recipient2.add_merge_data("Name", "Recipient2")
message.add_to_recipient(recipient2)

response = client.send(message)
