Bulk Mail Sending Through AWS SES

I am using Amazon AWS SES to send my email campaigns. I have around 35,000 subscribers on my list. At present I am using a code something similar to the following.

for (Entry<Integer, String> emailEntry : email_ids.entrySet()) {
        MimeMessage msg = getMimeMessage(emailEntry.getKey(), emailEntry.getValue());
        ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
                msg.writeTo(outputStream);
        RawMessage rawMessage = new RawMessage(ByteBuffer.wrap(outputStream.toByteArray()));

        ses.sendRawEmail(new SendRawEmailRequest(rawMessage));
    }

This way I was able to send email to all my subscribers the way I wanted. But there was a huge bill accounting to Data transfer. Each MimeMessage is of 150Kb in size and sending it to 35,000 subscribers resulted in 5.5 GB of data transfer.

So I decided to use BulkTemplateEmail in my application, to create the template once and send it to 35,000 emails. This way the email has to be send to SES only once and there will be significant gain in terms of data transfer.

Can anyone provide me a sample to do this via Java AWS SDK? I want to add List-Unsubscribe header on each Destination. This is where I am actually stuck. Couldn't find any methods to add custom email headers for each Destination. Is this possible with BulkTemplateEmail?

Any info is highly appreciated.

When sending emails using SES, Amazon charges for data transfer out. The current price is $0.12 per GB. For large volumes of emails this can result in serious charges.

For embedded images, attachments, etc. another solution is to use links instead of embedded objects. This way you can mitigate and reduce data transfers fees. This can have a moderate to high impact for email campaigns where a lot of emails are never opened, thereby saving on the data transfer charges.

If your links reference files on your EC2 instances, remember that you will still be charged for Data-Out from your EC2 instances. S3 will provide a lower cost.
