You need to provide Conditions in CloudFormation template. That will get used while creating resource. Something like below.

Parameters:
    EnvType:
      Description: Environment type.
      Default: test
      Type: String
      AllowedValues:
        - prod
        - test
      ConstraintDescription: must specify prod or test.
Conditions:
  CreateProdResources: !Equals 
    - !Ref EnvType
    - prod

Consider using Fn::FindInMap:

Parameters:
  EnvType:
    Default: qa
    Type: String
    AllowedValues:
      - qa
      - stg
      - prd
  Mappings:
    SettingsMap:
      qa:
        Protocol: Email
        Endpoint: Email
      stg:
        Protocol: Email
        Endpoint: Email 
      prd:
        Protocol: https
        Endpoint: https

and then:

Subscription:
  Protocol: !FindInMap
    - SettingsMap
    - !Ref EnvType
    - Protocol
