Formal Thank You Letter Closings
When to Use Formal Endings
Formal closings work best in professional settings such as after job interviews, when writing to supervisors, or when thanking clients. They create distance and show respect to the recipient.
A senior manager might expect more formality than a colleague you work with daily. New business relationships typically require formal closings until a more casual rapport develops.
Many industries like law, finance, and government expect traditional formality in written communication. When in doubt about the appropriate level, selecting a conservative closing demonstrates professionalism.
You can mirror the tone used by the recipient in previous communications. If they signed off formally, you might want to respond similarly.
Examples of Polite Closings
Below are professional closings you might consider for your formal thank you letters:
- Sincerely,
- Respectfully,
- Kind regards,

- Most sincerely,
- Yours faithfully,
- With deepest thanks,
- Respectfully yours,
- With warm regards,
- With sincere gratitude,
- Most respectfully,
- Professionally yours,
- With thanks and appreciation,
These closings can be paired with your full name, job title, and company name to add extra formality.
For the most formal situations, you could add your professional credentials after your name.
