after testing I've putted back the orignal to mail
May its going to "info@hagemann-systems.de" spam

Correct above setence

Sure! Here's a corrected and more professional version of your sentence:

—

I've just checked the contact form email issue using both our Nethues and Gmail accounts, and the emails were successfully received.
After testing, I've reverted the recipient email back to the original one.
It’s possible that the emails are going to the **info@hagemann-systems.de** spam folder.
Could you please share the cPanel details so I can investigate further?

Let me know if you want it to sound more formal or more casual!
