view email as dialog response in Watson Conversation

Next, I'm developing a bot on Watson and it's pretty much done, except for one detail: In a dialog where the user requests contact information from the company I wanted to pass an email with the reply but on account of the " "The email is not displayed, perhaps because of conflicts with the mechanism to detect entities. It seems simple but it has consumed me a lot of time trying to solve and I can not find anything that solves this problem. The closest I got was to write the email in environment variables, but they do not hold, and they disappear. If I initialize the variable from JSON, the same error occurs, the email is not read from the "@". Thank you in advance for helping me!
