AWS::Cognito::UserPool EmailConfiguration - AWS CloudFormation

AWS::Cognito::UserPool EmailConfiguration

The email configuration of your user pool. The email configuration type sets your preferred sending method, AWS Region, and sender for messages from your user pool.


To declare this entity in your AWS CloudFormation template, use the following syntax:


{ "ConfigurationSet" : String, "EmailSendingAccount" : String, "From" : String, "ReplyToEmailAddress" : String, "SourceArn" : String }


ConfigurationSet: String EmailSendingAccount: String From: String ReplyToEmailAddress: String SourceArn: String



The set of configuration rules that can be applied to emails sent using Amazon SES. A configuration set is applied to an email by including a reference to the configuration set in the headers of the email. Once applied, all of the rules in that configuration set are applied to the email. Configuration sets can be used to apply the following types of rules to emails:

  • Event publishing – Amazon SES can track the number of send, delivery, open, click, bounce, and complaint events for each email sent. Use event publishing to send information about these events to other AWS services such as SNS and CloudWatch.

  • IP pool management – When leasing dedicated IP addresses with Amazon SES, you can create groups of IP addresses, called dedicated IP pools. You can then associate the dedicated IP pools with configuration sets.

Specifies whether Amazon Cognito uses its built-in functionality to send your users email messages, or uses your Amazon Simple Email Service email configuration. Specify one of the following values:


When Amazon Cognito emails your users, it uses its built-in email functionality. When you use the default option, Amazon Cognito allows only a limited number of emails each day for your user pool. For typical production environments, the default email limit is less than the required delivery volume. To achieve a higher delivery volume, specify DEVELOPER to use your Amazon SES email configuration.

To look up the email delivery limit for the default option, see Limits in the Amazon Cognito Developer Guide.

The default FROM address is To customize the FROM address, provide the Amazon Resource Name (ARN) of an Amazon SES verified email address for the SourceArn parameter.


When Amazon Cognito emails your users, it uses your Amazon SES configuration. Amazon Cognito calls Amazon SES on your behalf to send email from your verified email address. When you use this option, the email delivery limits are the same limits that apply to your Amazon SES verified email address in your AWS account.

If you use this option, provide the ARN of an Amazon SES verified email address for the SourceArn parameter.

Before Amazon Cognito can email your users, it requires additional permissions to call Amazon SES on your behalf. When you update your user pool with this option, Amazon Cognito creates a service-linked role, which is a type of role in your AWS account. This role contains the permissions that allow you to access Amazon SES and send email messages from your email address. For more information about the service-linked role that Amazon Cognito creates, see Using Service-Linked Roles for Amazon Cognito in the Amazon Cognito Developer Guide.

The ARN of a verified email address or an address from a verified domain in Amazon SES. You can set a SourceArn email from a verified domain only with an API request. You can set a verified email address, but not an address in a verified domain, in the Amazon Cognito console. Amazon Cognito uses the email address that you provide in one of the following ways, depending on the value that you specify for the EmailSendingAccount parameter:

  • If you specify COGNITO_DEFAULT, Amazon Cognito uses this address as the custom FROM address when it emails your users using its built-in email account.

  • If you specify DEVELOPER, Amazon Cognito emails your users with this address by calling Amazon SES on your behalf.

The Region value of the SourceArn parameter must indicate a supported AWS Region of your user pool. Typically, the Region in the SourceArn and the user pool Region are the same. For more information, see Amazon SES email configuration regions in the Amazon Cognito Developer Guide.
