Not receiving emails from Formbuilder

I am using kirby 3 Formbuilder plugin (amazing btw) but I am having an issue with receiving emails - I am testing from a live server and the Received Submissions are being successfully logged but no emails come through

Any ideas what might be going wrong here?

Not familiar with the plugin.

Have you set up any transport config settings via SMTP or are you just sending mail without any further settings?

I guess the Received Submissions means that mail is in fact sent without errors. Have you checked your spam folder? Sending mail through PHP’s sendmail without using an SMTP server and proper email configuration is usually more gambling than anything else.

Did it work from your local dev environment?
