Kartheek,

Can you tell us which Epi version you are using? Also, are you using the new Forms add-on (the one documented on this page:https://world.episerver.com/documentation/developer-guides/forms/)?

Hey, Kartheek,

I have an email element block. It is built as an Add-On, but you could take it for inspiration.

Btw, where did you place your cshtml?
