Ok, thanks. I checked the employees settings and the SuperAdmin uses the gmail email address I use for everything in my shop, and also the language is set to NL. I switched it to EN and tried the contact form again, but still no email for admin. The test email still did not work either when SuperAdmin language is set to EN. I only have EN en NL set up as languages in my shop, and those are the only options available when I look at the employee settings.
Also, the emails do show up in the Advanced Parameters/Emails as "new message received through the contact form". They just don't get forwarded to the gmail address I added
