Contact form going to spam

The Contact Form will not allow me to use a Gmail address. I have searched and searched and can’t find any form that will allow me to use an address that is not the same as the website url.
This client will only use their gmail address. Do you know of any contact form that has this capability?
Thank you in advance.

Hello there,

As you are using SiteOrigin’s contact form, you could find a solution in this thread.
