We have a view which can be filtered. We need a block which can be used to send a message with the recipients coming from the view. Ideally this would be on the same page. This would be used by anonymous users so the interface needs to be simple. We have tried views send but the form is too complex to present to anonymous users.
Possibly an entity form where we can define the fields, user selects the recipients from the view, fills the simple block form and send.
Any ideas much appreciated.
