[Plugin: Contact Form 7] Simply does not work

In my case, the message was sent but the tags weren’t replaced by inserted details (full name, email address, subject, message).
Full email content:

From: [your-name] <[your-email]>
Subject: [your-subject]

Message Body:
[your-message]

This mail is sent via contact form on Host Cloud WordPress Template

Solved. In fact, when using wpcf7, the tags sent by email should be the same as ones used in the form. My theme had an already setup contact form but those shortcodes weren’t used on form; these is why that happened.
For those that found this topic, take care to use the codes as:
[text* value ...]
And for email template use similar to:
From: [value] <email_value> and so on

How come if someones sends a Gmail email it doesn’t send through???…
