Linking URL to post

This is a really specific problem, and possibly not achievable, but I thought I’d ask.

When emails arrive, they will always have a link included within the body of the email. Once the email is converted to a post, I’m displaying the posts using a Divi Blog Grid. This displays the posts but has all the links that would normally be clickable, turned off, so post title, author, category are no longer clickable.

What I want to be able to do is to make the whole post block (so that element of the grid) clickable, linked to the URL that arrived in the email.

I thought this might be possible if I could assign the post a specific css class, but I haven’t spotted how to do that yet.

I could do it manually within the post if I was creating them manually, but I’d like Postie to automate it, ideally.

It might just not be possible, but was worth the question I thought.
