Lost phone? Send them a nice call offering a reward.
Is $50 asking to much for your $800 phone back? I didn't think so. Use this in conjunction with a DO recipe for sending an email to firstname.lastname@example.org with '#lostphone' in the title. Modify the message to include other methods of contacting you (especially if your email in incomprehensible). You can also use this with the recipe I created that sends a notification message with the same offer since they may not answer the phone.
