How can I use Rules to send an e-mail to the author of a node linked by an entity reference field? I have a content type called Help Wanted.  I have another content type called Reply to Help Wanted.  The reply content type includes an entity reference field that contains a node reference to the original help wanted ad being replied to.

I am trying to use Rules to send an e-mail when a reply is posted to the author of the original Help Wanted post.

However, I don't know what to put in the To field of the Send mail action.  I tried the following:

[node:field_my_entityreference:author:mail]


But this token didn't work.  I also tried several other variations to no effect.  Is it possible to use tokens to get the author's e-mail of a node linked by entity reference?  If not, how do I get the author's e-mail via the entity reference?
Here's how I got mine to work:


Switch to 'Data selection mode' which is not how the mail action launches by default:

Select through the field sequence just like you already had with tokens!



I noticed that the tokens are otherwise not available if you just use the direct input mode.  Weird!
