Dear [Recipient's Name],

I wanted to reach out and apologize for my late arrival to our [meeting/appointment]. I know how important it is to be punctual, and I'm truly sorry for any inconvenience my tardiness may have caused.

Unfortunately, [briefly explain the reason for your late arrival, e.g. "I got stuck in traffic" or "I had an unexpected issue at home"]. I should have left earlier to account for any delays, and I'll make sure to plan better for our next [meeting/appointment].

Please know that I value our [relationship/project] and appreciate your understanding in this matter. If there's anything I can do to make up for the lost time, please let me know.

Thank you for your understanding, and I look forward to catching up with you soon.

Best regards,
