Using AWS Lambda with Amazon SES

When you use Amazon SES to receive messages, you can configure Amazon SES to call your Lambda function when messages arrive. The service can then invoke your Lambda function by passing in the incoming email event, which in reality is an Amazon SES message in an Amazon SNS event, as a parameter.

Example Amazon SES Message Event

{ "Records": [ { "eventVersion": "1.0", "ses": { "mail": { "commonHeaders": { "from": [ "Jane Doe <janedoe@example.com>" ], "to": [ "johndoe@example.com" ], "returnPath": "janedoe@example.com", "messageId": "<0123456789example.com>", "date": "Wed, 7 Oct 2015 12:34:56 -0700", "subject": "Test Subject" }, "source": "janedoe@example.com", "timestamp": "1970-01-01T00:00:00.000Z", "destination": [ "johndoe@example.com" ], "headers": [ { "name": "Return-Path", "value": "<janedoe@example.com>" }, { "name": "Received", "value": "from mailer.example.com (mailer.example.com [203.0.113.1]) by inbound-smtp.us-west-2.amazonaws.com with SMTP id o3vrnil0e2ic for johndoe@example.com; Wed, 07 Oct 2015 12:34:56 +0000 (UTC)" }, { "name": "DKIM-Signature", "value": "v=1; a=rsa-sha256; c=relaxed/relaxed; d=example.com; s=example; h=mime-version:from:date:message-id:subject:to:content-type; bh=jX3F0bCAI7sIbkHyy3mLYO28ieDQz2R0P8HwQkklFj4=; b=sQwJ+LMe9RjkesGu+vqU56asvMhrLRRYrWCbV" }, { "name": "MIME-Version", "value": "1.0" }, { "name": "From", "value": "Jane Doe <janedoe@example.com>" }, { "name": "Date", "value": "Wed, 7 Oct 2015 12:34:56 -0700" }, { "name": "Message-ID", "value": "<0123456789example.com>" }, { "name": "Subject", "value": "Test Subject" }, { "name": "To", "value": "johndoe@example.com" }, { "name": "Content-Type", "value": "text/plain; charset=UTF-8" } ], "headersTruncated": false, "messageId": "o3vrnil0e2ic28tr" }, "receipt": { "recipients": [ "johndoe@example.com" ], "timestamp": "1970-01-01T00:00:00.000Z", "spamVerdict": { "status": "PASS" }, "dkimVerdict": { "status": "PASS" }, "processingTimeMillis": 574, "action": { "type": "Lambda", "invocationType": "Event", "functionArn": "arn:aws:lambda:us-west-2:012345678912:function:Example" }, "spfVerdict": { "status": "PASS" }, "virusVerdict": { "status": "PASS" } } }, "eventSource": "aws:ses" } ] }
