Set headers when sending emails with Cognito

How can I set specific email headers when sending emails through cognito custom emails system? More precisely I'd like to set the 'X-Entity-Ref-ID' header to avoir threading in recipient inboxes.

CustomMessage lambdas has no header method in the response json CustomEmailSender could work but feels overkill.

Thanks

This is not implemented in the triggers unfortunately.

With Amazon Cognito, Custom message Lambda trigger, you can only set the following:

"smsMessage": "string",
"emailMessage": "string",
"emailSubject": "string"

You cannot set the email headers as of now. However using a different subject line may allow you to not group emails from being shown as a threads without using "X-Entity-Ref-ID".

So the only solution to this problem is to use a CustomEmailSender and add the header in that lambda. A lot more code to write to access SES but more control. A shame, access to settings headers on emails would simplify all this.
