Use a managed SES IP pool in Terraform by default

I'd like to configure Terraform with a default SES configuration set that sends through an AWS managed IP pool. So far I have this:

resource "aws_sesv2_dedicated_ip_pool" "this" {
  pool_name = "default-app"
  scaling_mode = "MANAGED"
}

resource "aws_ses_configuration_set" "this" {
  name = "default-app"
}

I don't see how to set this as the default or how to associate the two in Terraform.

You have to use the Terraform SES v2 resources for managing the configuration set, as well as the SES identity, to make this work:

# Create an IP Pool
resource "aws_sesv2_dedicated_ip_pool" "this" {
  pool_name = "default-app"
  scaling_mode = "MANAGED"
}

# Create a configuration set that uses the IP pool
resource "aws_sesv2_configuration_set" "this" {
  configuration_set_name = "default-app"

  delivery_options {
    sending_pool_name = aws_sesv2_dedicated_ip_pool.this.pool_name
  }
}

# Create an email identity that uses the configuration set by default
resource "aws_sesv2_email_identity" "this" {
  email_identity         = "example.com"
  configuration_set_name = aws_sesv2_configuration_set.this.configuration_set_name
}
