We have a form at https://telescopicmast.com/msb6-basic/receive-a-quotation/

It would be great if the THANK YOU message could have a styled background (in my case blue). Now it shows up quite ugly... (see image here)

OR even better would be the option to have the sender redirected to a page on my domain.

Anyone that has a temporary solution for this?


(by the way: attaching a file is not possible, saying my image is larger than 500 Mb)
