Apologize Missed Deadline

Dear Sir,

I apologize for not getting the brochure materials to you on time. Unfortunately, we needed some changes in the art work, and they will take several more days to complete. I should have all the materials ready by Tuesday of next week, and will deliver them to you personally at that time. I would appreciate your printing the brochures as soon as possible after that.

I realize that this tardiness affects your printing schedule, and apologize for any inconvenience this delay may have caused you.

Faithfully Yours,
[Your Name]

Apologize for a Missed Deadline

Dear Madame,

We are sorry that we were unable to deliver your furniture yesterday. Because we have only two delivery people, we were left shorthanded when one of them became ill.

To ensure that this does not happen again, we have hired temporary workers and rescheduled your delivery appointment for 9:00 a.m. Friday morning. We appreciate your patience. Your business is important to us, and we hope that this incident will not hurt our relationship.

Faithfully Yours,
[Your Name]
