Google Inbox Pinned to Wunderlist
Use e-mail address "firstname.lastname@example.org" in the "To address" field and make sure the mailbox you are using for pinning the messages is the same you used to sign up on Wunderlist. This recipe is based on Wunderlist's ability to create tasks by sending mails to "email@example.com". Wunderlist uses the subject of the mail to create a task list and the first line of the body to create the task. If you leave the subject alone, the task will be sent directly to Wunderlist inbox. You can edit the task and the task list later on Wunderlist.
