I have a pertinent question about Auto-Reply.

I want to reply with the same subject as I received the email and I don't know how to do that.

For example: (My customer sends me an email with the subject "Purchase", how do I Auto-Reply with the same subject?

In other providers, for example, it has a parameter that would be this _{%subject%}.

So my auto reply would be configured like this in the subject:

Re: {%subject%}

Could you help me in this regard
