This free plugin from DiviLife is wonderful. Coupled with the power of Divi’s Theme Builder you can redirect visitors to a page built with Divi. The Theme Builder comes into play as you can easily remove/hide site menus or footers from your bespoke coming soon page.

Here is the text excerpt and link for the Divi Coming Soon page:

“Divi Coming Soon allows you to use the power of Divi to create gorgeous and effective Coming Soon Pages, Maintenance Mode Pages, and Under Construction Pages. Create your own layout or use one of our professionally designed Coming Soon Pages (sold separately). Once you assign your Coming Soon Page in Settings, all traffic (except logged in Admins and Editors) will be automatically redirected to your chosen Coming Soon Page!”
