[Plugin: Fast Secure Contact Form] Sends to wrong email address

I’ll try again again! My last attempt disappeared.
I cannot get the contact form to send email to my new (domain name based) address. Keeps sending to the old one despite there being no record of it anymore in the settings. I updated it with the new address.
I’ve installed and uninstalled, checked boxes and unchecked…I’ve run out of things to try and it’s been over a week now.
Is there another contact form worth trying instead?
