Obtaining Mailgun API Credentials

To send emails using the Mailgun API, you need to set up API credentials and obtain an API key and domain.

Steps

1. Sign up for Mailgun:

• Go to Mailgun.
• Sign up for an account if you don't already have one.

2. Add and verify your domain:

• Navigate to "Sending" > "Domains".
• Click "Add New Domain".
• Follow the instructions to add and verify your domain.

3. Create an API Key:

• Navigate to "Settings" > "API Keys".
• Note down the "Private API Key".

4. Update the Mailgun settings in the mailgun_email_sender.go file:

domain := "your-mailgun-domain"
apiKey := "your-mailgun-api-key"

5. Run the example function to test the email sending:

// Replace these with your actual values (in production, retrieve from a secure file or secret manager)
domain := "your-mailgun-domain"
apiKey := "your-mailgun-api-key"

// Create MailgunEmailSender with the domain and API key
emailSender, err := NewMailgunEmailSender(domain, apiKey)
if err != nil {
    log.Fatalf("Failed to create email sender: %v", err)
}

// Read attachment content
attachmentContent, err := os.ReadFile("path/to/attachment.jpg")
if err != nil {
    log.Fatalf("Failed to read attachment: %v", err)
}

// Define email message
message := gomail.NewEmailMessage("[email protected]",[]string{"[email protected]"}, "Test Email with attachment", "This is the plain text part of the email.").
		SetHTML("<p>This is the <b>HTML</b> part of the <i>email</i>.</p>").AddAttachments(*gomail.NewAttachment("attachment.jpg", attachmentContent))

// Send email
if err := emailSender.SendEmail(message); err != nil {
    log.Fatalf("Failed to send email: %v", err)
}

fmt.Println("Email sent successfully")

Ensure your API key and domain are stored securely and refreshed appropriately.
