Add to Todoist via Mailbox App
If you use Todoist and Mailbox, you can use this Applet to add to-dos to Todoist when you slide a message out of your inbox and into a list named "Todoist" (or whatever name you prefer). Defaults to "today" for due date so you'll see it right away in Todoist. Tags new to-dos with "@Mailbox." For premium Todoist users, you can add the body of the email as a note to your to-do.
