New admin action for custom post types

Hi All,

I manage a product database with a custom post type. I added new columns to the admin panel with manage_posts_column filter.

Now, on one of these columns, I would like to add a specific admin action, for example : Sent by Email. When the Sent by Email link is hit within the admin panel, the plugin I work on is reloaded with this action.

How could I do that ?

Thank you for your help,
Looic.
