Quick Template (Short)

Hi [[NAME]], my order [[REFERENCE]] was due on [date] but hasn't arrived. Please provide a real-time tracking update and a revised delivery estimate today. Thanks, [[YOUR_NAME]].

Formal Version

Dear [[NAME]], I am writing to formally report that my shipment, reference number [[REFERENCE]], which was guaranteed for delivery on [date], remains undelivered. As per your service policy, I request an immediate status investigation, a definitive delivery timeline, and information regarding any applicable compensation for this breach of contract. I expect a substantive response within 24 hours. Sincerely, [[YOUR_NAME]].

Friendly Version

Hey team, hope you're well! I'm following up on my package [[REFERENCE]]—it was supposed to land on [date] but tracking has gone silent. Could you give me a quick peek at where it is and a solid ETA? Really need it for the weekend! Cheers, [[YOUR_NAME]].

Firm Version

[[NAME]], this is a second attempt to resolve the non-delivery of order [[REFERENCE]], now 5 days past the promised date. Your standard tracking links are unhelpful. I require escalation to a supervisor, a confirmed delivery date within 48 hours, and a credit for the shipping fee by close of business today. Failure to resolve this will necessitate a formal dispute and review of our business relationship. [[YOUR_NAME]].

Subject Lines (Pick one)

  • URGENT: Non-receipt of Order [[REFERENCE]] – Action Required
  • Formal Complaint: Late Delivery for Ref [[REFERENCE]]
  • Following Up: Missing Package [[REFERENCE]] – Need Resolution

Tips

  • Mention the exact promised delivery date from your confirmation email.
  • Include the carrier's tracking number if you have one, even if it's not updating.
  • Specify a concrete consequence: 'I need this by Friday or I must cancel.'

FAQ

Q: Should I attach a screenshot of the original delivery promise?
A: Yes. Attaching a screenshot of the order confirmation with the delivery date is powerful, irrefutable evidence.

Q: What if the customer service email is a generic 'no-reply' address?
A: Find the specific department email (e.g., support@, complaints@, care@) or use the contact form, then follow up via phone citing the ticket number.
