+
+## Usage
+
+Below is an example of how to use the Unsend package to send an email and retrieve email information.
+
+### Environment Variables
+
+```bash
+export UNSEND_API_KEY="your-api-key"
+export UNSEND_API_URL="https://app.unsend.dev" # or your self-hosted URL
+```
+
+### Initialize
+
+```go
+client, err := unsend.NewClient()
+```
+
+### Sending Emails
+
+To send an email you will need to define the payload. After definition, you can use the `.SendEmail` method to send emails with the payload as a parameter.
+
+```go
+func main() {
+	godotenv.Load()
+
+	client, err := unsend.NewClient()
+
+	if err != nil {
+		fmt.Printf("[ERROR] - %s\n", err.Error())
+		os.Exit(1)
+	}
+
+	request := &unsend.SendEmailRequest{
+		To: []string{"youremail@gmail.com"},
+		From: "hello@yourdomain.com",
+		Subject: "Unsend test email",
+		Text: "hello,\n\nUnsend is the best open source sending platform",
+		Html: "<p>hello,</p><p>Unsend is the best open source sending platform</p><p>check out <a href='https://unsend.dev'>unsend.dev</a></p>",
+	}
+
+	response, err := client.Emails.SendEmail(context.Background(), *request)
+
+	if err != nil {
+		fmt.Printf("[ERROR] - %s\n", err.Error())
+		os.Exit(1)
+	}
+
+	fmt.Printf("[SUCCESS] - %s\n", response.EmailId)
+}
+
+```
+
+### Retrieve Emails using the id
+
+The email will be retrieved using the ID you get after sending the mail.
+
+```go
+func main() {
+	godotenv.Load()
+
+	client, err := unsend.NewClient()
+
+	getEmailRequest := unsend.GetEmailRequest{
+		EmailId: "your-email-id",
+	}
+
+	email, err := client.Emails.GetEmail(context.Background(), getEmailRequest)
+
+	if err != nil {
+		fmt.Printf("[ERROR] - %s\n", err.Error())
+		os.Exit(1)
+	}
+
+	fmt.Printf("[SUCCESS] - %s\n", email.Id)
+}
+```
