+Resend mass mailings
+====================
+
+A frequent need for users of mass mailings is to resend one mailing that has
+already been sent in the past to new recipients that haven't received yet that
+mail. But the problem is to know which are the applicable ones.
+
+Odoo already includes a method in its mass mailing logic that avoids to resend
+the same mail 2 times for one mass mailing, and for v9, there was a trick that
+allows to modify the state of a mass mailing from kanban view, covering the
+need.
+
+But now on v10 both status bar in form view and dragging between states in
+kanban are not allowed.
+
+This module introduces a button to restart a mass mailing to draft state,
+allowing you to reevaluate the sending domain or list for performing again
+the mailing.
+
+Usage
+=====
+
+* Go to *Mass mailing > Mailings > Mass Mailings*.
+* Click on one record that is done or create a new one and send it.
+* You will see a button called "Resend".
+* If you click on it, mass mailing will be set to Draft again.
