Use the same snippet in the Reply-To:
In your case, if [your-email] is used in form, use Reply-To: [your-email].
Reply-To: is the address you will reply to, once you press Reply. Therefore, make sure it holds the same snippet that you use for where the person fills the contact form email field.
I JUST got to the same conclusion and came to check. Yes, for my/clients websites too the messages are being delivered successfully, but there is no success message.
I am also using Contact Form 7 Email Spam Blocker and the error messages for set spam emails aren’t appearing either.
Couldn’t revert back to older versions.
