Publish to Amazon SNS topic action
The SNS action publishes the mail using an Amazon SNS notification. The notification includes the complete email content. This action has the following options.
-
SNS Topic—The name or ARN of the Amazon SNS topic to which to publish the emails. The Amazon SNS notifications will contain a raw, unmodified copy of the email, which is typically in Multipurpose Internet Mail Extensions (MIME) format. For more information about MIME format, see RFC 2045
. Important
If you choose to receive your emails through Amazon SNS notifications, the maximum email size (including headers) is 150 KB. Larger emails will bounce. If you anticipate emails larger than this size, save the emails to an Amazon S3 bucket instead.
An example of an Amazon SNS topic ARN is arn:aws:sns:us-east-1:123456789012:MyTopic. You can also create an Amazon SNS topic when you set up your action by choosing Create SNS Topic. For more information about Amazon SNS topics, see the Amazon Simple Notification Service Developer Guide.
Note
The Amazon SNS topic you choose must be in the same AWS region as the Amazon SES endpoint you use to receive email.
-
Encoding—The encoding to use for the email within the Amazon SNS notification. UTF-8 is easier to use, but may not preserve all special characters when a message was encoded with a different encoding format. Base64 preserves all special characters. For information about UTF-8 and Base64, see RFC 3629
and RFC 4648 , respectively.
When you receive an email, Amazon SES executes the rules in the active receipt rule set. You can configure receipt rules to send you notifications using Amazon SNS. Your receipt rules can send two different types of notifications:
-
Notifications sent from SNS actions – When you add an SNS action to a receipt rule, it sends information about the email as well as the email's content. If the message is 150KB or smaller, this notification type also includes the complete MIME body of the email.
-
Notifications sent from other action types – When you add any other action type (including Bounce, Lambda, Stop Rule Set, or WorkMail actions) to a receipt rule, you can optionally specify an Amazon SNS topic. If you do, you will receive notifications when these actions are performed. These notifications contain information about the email, but do not contain the content of the email.
The following topics describe the contents of these notifications and provide an example of each type of notification:
