Fast Secure Contact Form only sending email to mobile device

Already went through all the troubleshooting online and I’m still getting this error.

I’m getting the results of the contact form sent to my iPhone through my synced gmail account.

However, I can’t access the email through my actual email account on a web browser (and it’s not in spam). I’m guessing it’s something mixed up with the plugin itself or the settings, as I’ve never had this problem with any other email. Any email I’ve ever received on my iPhone, I’ve been able to access online. I’ve tried using different browsers. Nothing. But it’s on my iPhone.

Weird.
