Post ID in email action?

After a form is filled out there are 2 actions triggered:

– Create a new post
– Send an email to admin

I would like to use the post ID of the created post within the email action so I can add a direct link for the admin to open this particular post by 1 click.

f.i.: Open post

What does not work:
{current:post} (opens the page where the form is implemented)
{current:post:ID} (opens the page where the form is implemented)

Any shortcode available for this or code option to create one myself?
