How are you sending email? ie where are your contact forms sending to? A lot of mail providers (gmail, outlook, yahoo, etc.) are getting very strict about where and how email is formatted.
@ahmetyo1, first of all, contact your hosting provider. Sending mail is a feature, which you might just lack.
hi i am trying to sending it to gmail!
hello mr.vasili4 what exactly should I tell my hosting provider?
@ahmetyo1, if you are able, try first to send a test email using just php mail function.
If that doesn’t work, tell your hosting provider you’re not able to send emails.
Hello,
after I updated WordPress to 4.6 my already working Contact Form 7 (for several weeks) now stopped to send e-mails to me.

I switched to PHP 7, but that doesn’t change it.
Thank You for answering!

The sending e-mail had to be an existing one like info@thiel-fensterbau.de – not wordpress@thiel-fensterbau.de
I had to change it on several webpages, not on all!
Thank You!
