How to create a logic for sending mails with Go and AWS SES

That was a little tough for me because I didn’t have any knowledge of them. I’ve managed to get it so I’ll summarize them.

The code

package mailer

import (
  "context"
  "fmt"
  "os"

  "github.com/aws/aws-sdk-go-v2/config"
  "github.com/aws/aws-sdk-go-v2/service/sesv2"
  "github.com/aws/aws-sdk-go-v2/service/sesv2/types"
)

func Send(message string) bool {
  from := os.Getenv("MAIL_FROM")
  recipients := []string{os.Getenv("MAIL_RECIPIENTS")}
  region := "XXXX"
  subject := "You've gotten an message from a user!"

  ctx := context.Background()
  cfg, err := config.LoadDefaultConfig(ctx, config.WithRegion(region))
  if err != nil {
    fmt.Println(err)
  }
  client := sesv2.NewFromConfig(cfg)
  input := &sesv2.SendEmailInput{
  FromEmailAddress: &from,
  Destination: &types.Destination{
    ToAddresses: recipients,
  },
  Content: &types.EmailContent{
    Simple: &types.Message{
      Body: &types.Body{
         Text: &types.Content{
         Data: &message,
      },
    },
    Subject: &types.Content{
      Data: &subject,
    },
   },
  },
 }
 res, err := client.SendEmail(ctx, input)
 if err != nil {
   fmt.Println(err)
   return false
 }
 fmt.Println(res.MessageId)
 return true
}

and

AWS_SECRET_KEY=XXXXXXXXXXX
AWS_ACCESS_KEY_ID=XXXXXXXXXXXX

That’s all.

If you are using Docker, you have to add like below in Dockerfile.

RUN go get github.com/aws/aws-sdk-go-v2/config
RUN go get github.com/aws/aws-sdk-go-v2/service/sesv2
RUN go get github.com/aws/aws-sdk-go-v2/service/sesv2/types
