After tracking Drupal 8 for a while back in spring 2015, this is the first release that works with D8. The code is crappy (seriously), only sending the message directly (using the Batch API) is tested, integration with Token module is untested and so on, but:
It works! Views Send specific tokens (the fields from the view) are replaced and e-mails are successfully sent using the Batch API.
PS1! When configuring the the Views Send field in the view, just ignore the actions listed.
PS2! Patches are welcome. There is plenty to fix.
