🐛 Bug Report: Variable not Working in Subject with SMTP Email Provider

[kaptinlin]

📜 Description

When using the variable {{subscriber.lastName}} in the Subject line with the SMTP email provider, the variable is not getting replaced with the actual value. Instead, it only shows "Hello, " as the result.

  "subscriber": {
    "lastName": "John"
  }
}

👟 Reproduction steps

1. Send an email using SMTP email provider with the subject as Hello, {{subscriber.lastName}}.
2. Check the received email.

The subject of the email should be "Hello, John".

@kaptinlin @jainpawan21 @scopsy we would like to pick this up

the issue is with the name subscriber, its getting overwritten by one of the internal entities with the same name, if you name it subscriber1 or anything other than subscriber it should work fine, changing the logic to support exact message payload is recommended but required some careful code refactoring
@kaptinlin @scopsy @jainpawan21
i'd like to fix this as well
