AWS SES SDK send email with attachments

Issue

I’m using the official AWS Golang SDK to integrate with SES but can’t find any information about how to add some attachments (pdf file represented as []byte in code) to the email.

Could you help me?

The current email sending code looks like this:

sesEmailInput := &ses.SendEmailInput{
    Destination: &ses.Destination{
        ToAddresses: []*string{aws.String("To address")},
    },
    Message: &ses.Message{
        Subject: &ses.Content{
            Data: aws.String("Some text"),
        },
        Body: &ses.Body{
            Html: &ses.Content{
                Data: aws.String("Some Text"),
            },
        },
    },
    Source: aws.String("From address"),
    ReplyToAddresses: []*string{
        aws.String("From address"),
    },
}
if _, err := s.sesSession.SendEmail(sesEmailInput); err != nil {
    return err
}

Solution

To send attachments, use the SendRawEmail API instead of SendEmail. AWS documentation will generally refer to this as constructing a ‘raw message’ instead of explicitly calling out how to send attachments.

Example

From the AWS SDK for Go API Reference, linked below:

params := &ses.SendRawEmailInput{
    RawMessage: &ses.RawMessage{ // Required
        Data: []byte("PAYLOAD"), // Required
    },
    ConfigurationSetName: aws.String("ConfigurationSetName"),
    Destinations: []*string{
        aws.String("Address"), // Required
        // More values...
    },
    FromArn:       aws.String("AmazonResourceName"),
    ReturnPathArn: aws.String("AmazonResourceName"),
    Source:        aws.String("Address"),
    SourceArn:     aws.String("AmazonResourceName"),
    Tags: []*ses.MessageTag{
        { // Required
            Name:  aws.String("MessageTagName"),  // Required
            Value: aws.String("MessageTagValue"), // Required
        },
        // More values...
    },
}
resp, err := svc.SendRawEmail(params)
