                    String attContent = s3.getObjectAsString(emailServiceConfiguration.getAttachmentS3Bucket(), attachment.getPath());
                    DataSource source = new ByteArrayDataSource(attContent.getBytes(),"application/png");
                    att.setDataHandler(new DataHandler(source));
                    msg.addBodyPart(att);

Q: Can Amazon SES send emails with attachments?

You can also send email with attachments programmatically. To include an attachment in your email, construct a new multipart email message. In the message, include a MIME part that contains an appropriate Content-Type header, along with the MIME-encoded content. Next, use the Content-Disposition header to specify whether the content is to be displayed inline or treated as an attachment.

Once you've composed your message, you can use the SendRawEmail API operationto send

i'm able to send email, but the issue is that attachment images are corrupt upon receiving the email – 24Circles Feb 12 '21 at 13:08
@24Circles it might be because of the missing `MIME-encodeding` – samtoddler Feb 12 '21 at 13:09

Instead of getting the bytes from string, use byte array

MimeBodyPart att = new MimeBodyPart();
att.setFileName(attachment.getFileName());
S3Object s3Object = s3.getObject(emailServiceConfiguration.getAttachmentS3Bucket(), attachment.getPath());
byte[] byteArray = IOUtils.toByteArray(s3Object.getObjectContent());
DataSource source = new ByteArrayDataSource(byteArray,"application/png");
att.setDataHandler(new DataHandler(source));
msg.addBodyPart(att);
