AWS SES does not send emails using SendRawEmail operation - amazon-web-services

Question

I have troubles sending emails with AWS golang sdk using SendRawEmail operation. Even though I get no errors and receive MessageId back from AWS, I do not receive the email.
Sending emails using SendEmail works fine and I receive the email.
My code:
session, err := session.NewSession()
if err != nil {
return err
}
svc := ses.New(session, &aws.Config{Region: aws.String("eu-west-1")})
messageContent := `From: "Alice" <xxx#xxx>
To: "Bob" <xxx#xxx>
Return-Path: <xxx#xxx>
Subject: Hello
Content-Language: en-US
Content-Type: text/plain; charset="us-ascii"
MIME-Version: 1.0
This is a test email`
base64messageContent := base64.StdEncoding.EncodeToString([]byte(messageContent))
source := aws.String("xxx#xxx")
destinations := []*string{aws.String("xxx#xxx")}
message := ses.RawMessage{Data: []byte(base64messageContent)}
input := ses.SendRawEmailInput{Source: source, Destinations: destinations, RawMessage: &message}
output, err := svc.SendRawEmail(&input)
if err != nil {
return err
}
log.Println("Response from SES", output)
return nil
}
I am using my Gmail as the destination email, if that makes any difference.

Data in RawData should not be base64 encoded. As documentation states:
// Data is automatically base64 encoded/decoded by the SDK.
