Post Data contact form

Hello! I added a field for a phone number in the property contact form. The field is now in the contact form and required to fill in, but the phone number doesn´t appear in the e-mail I receive when people send a message. Can anyone tell me where I can find the post data of these fields?
Thanks in advance!

You need to configure the plugin assuming it’s CF7, this is the documentation:

Thank you for your answer, but my website doesn´t have the CF7 plugin

You need to contact your theme author, they are not entitled but they may provide support.
