Send Email Using Golang | SocketLabs Developers

The SocketLabs Email Delivery Golang 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.

import ( 
	"github.com/socketlabs/socketlabs-go/injectionapi"
	"github.com/socketlabs/socketlabs-go/injectionapi/message"
)

func main() {
	client := injectionapi.CreateClient(000001, "YOUR-API-KEY")

	basic := message.BasicMessage{}

	basic.Subject = "Sending a Basic Message"
	basic.HtmlBody = "<html>This is the Html Body of my message.</html>"
	basic.PlainTextBody = "This is the Plain Text Body of my message."

	basic.From = message.EmailAddress{EmailAddress: "[email protected]"}
	basic.ReplyTo = message.EmailAddress{EmailAddress: "[email protected]"}

	//A basic message supports up to 50 recipients and supports several different ways to add recipients
	basic.AddToEmailAddress("[email protected]")   //Add a To address by passing the email address
	basic.AddCcEmailAddress("[email protected]")  //Add a CC address by passing the email address and a friendly name
	basic.AddBccEmailAddress("[email protected]") //Add a BCC address by passing the email address

	//Send the message
	_, _ = client.SendBasic(&basic)
}

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.

import (
	"github.com/socketlabs/socketlabs-go/injectionapi"
	"github.com/socketlabs/socketlabs-go/injectionapi/message"
)

func main() {

	client := injectionapi.CreateClient(000001, "YOUR-API-KEY")

	//Build the message
	bulk := message.BulkMessage{}

	bulk.Subject = "Sending A Bulk Message"
	bulk.HtmlBody = "<html>This is the Html Body of my message sent to the recipient with %%EyeColor%% eyes.</html>";
	bulk.PlainTextBody = "This is the Plain Text Body of my message sent to the recipient with %%EyeColor%% eyes.";
	bulk.From = message.EmailAddress{EmailAddress: "[email protected]"}
	bulk.ReplyTo = message.EmailAddress{EmailAddress: "rep[email protected]"}
 
	//Add Bulk Recipients
	recipient1 := bulk.AddToFriendlyBulkRecipient("[email protected]", "Recipient #1")
	recipient1.AddMergeData("EyeColor", "Green")

	recipient2 := bulk.AddToFriendlyBulkRecipient("[email protected]", "Recipient #2")
	recipient2.AddMergeData("EyeColor", "Blue")

	//Send the message
	_, _ = client.SendBulk(&bulk)
}
