How to end an email: 75 professional sign-offs with examples

Choose a professional email closing for formal messages, client work, requests, follow-ups, thanks, sensitive conversations, and everyday team communication.

A professional email usually ends with three parts: a closing sentence that completes the message, a sign-off such as “Best regards,” and a signature identifying the sender. The best ending matches the relationship and purpose. It should not introduce a new request or force the recipient to guess what happens next.

The safest professional email sign-offs

01 / Best regards,Versatile and professional

A dependable choice for clients, partners, hiring conversations, and colleagues.

02 / Kind regards,Professional with warmth

Useful when you want a considerate tone without becoming informal.

03 / Regards,Brief and neutral

Efficient, though it can read cool in a sensitive conversation.

04 / Sincerely,Formal correspondence

Fits cover letters, official notices, and first contact in a formal setting.

05 / Thank you,A real expression of thanks

Best when the recipient has helped or the message contains a reasonable request.

06 / Best,Everyday business email

Short, modern, and appropriate for most established working relationships.

Formal sign-offs

Use these for official correspondence, first contact with a senior stakeholder, regulated contexts, applications, and situations where the relationship calls for distance. A formal sign-off works best with a complete name, role, organization, and relevant contact details.

Sincerely,
Yours sincerely,
Respectfully,
Respectfully yours,
With appreciation,
With sincere thanks,
Best regards,
Kind regards,
Warm regards,
Thank you for your consideration,
With gratitude,
All the best,

Warm but professional sign-offs

These fit established clients, teammates, vendors, and professional communities. Match the warmth already present in the conversation. “Warmly” may be natural after a generous exchange and distracting in a formal dispute.

Best,
All the best,
Warmly,
With thanks,
Many thanks,
Thanks again,
With appreciation,
Take care,
Have a great week,
Wishing you a productive week,
Looking forward to staying in touch,
Until next time,

Sign-offs for a request

A request should be easy to answer before the closing appears. State the deliverable and a real date or ask the recipient to propose one. Avoid making gratitude sound like the recipient has already agreed.

01 / Thank you,Could you send the signed copy by August 8?

Direct request with a clear deadline.

02 / I appreciate your help,Would you confirm which option you prefer?

Polite when assistance is genuinely involved.

03 / Best regards,If that timing does not work, please suggest an alternative.

Makes room for a realistic response.

04 / With thanks,Please reply with the account ID, but do not include a password.

Combines gratitude with a security boundary.

Thank you,
With thanks,
Many thanks,
I appreciate your help,
Thanks for taking a look,
Thank you for your time,
Thanks for considering this,
I appreciate your guidance,
Best regards,
Kind regards,

Follow-up and next-step sign-offs

Looking forward to your reply,
Looking forward to your feedback,
Looking forward to speaking,
Until our meeting,
Talk soon,
I'll follow up on Friday,
I'll send the revised draft tomorrow,
Please let me know what works,
Happy to discuss,
Here if questions come up,
Thanks for keeping me posted,
Best,

A sentence such as “I'll send the revised draft tomorrow” is technically a closing line, not a sign-off. That distinction is useful: concrete next steps belong in prose, while the sign-off can remain short. Do not capitalize every word or add a comma to a full closing sentence as though it were a valediction.

Client and customer sign-offs

Best regards,
Kind regards,
Thank you for your business,
Thank you for your continued trust,
We're glad to help,
Here if you need anything else,
Thanks for the thoughtful feedback,
We appreciate your patience,
Looking forward to the next step,
With appreciation,

Avoid “Thank you for your business” in an apology for a serious failure; it can sound automated. In support email, name the resolution and ownership first: “I have refunded the duplicate charge and will email the receipt within an hour.” Then close with “Sincerely” or “With appreciation,” depending on the tone.

Internal and team sign-offs

Thanks,
Best,
Sounds good,
On it,
Will do,
Talk soon,
See you then,
Thanks, everyone,
Appreciate it,
More tomorrow,

Short internal replies do not always need a formal sign-off. “Approved—please ship the current draft. Thanks, Maya” is complete. Do not add ceremony that makes a two-line operational answer harder to scan.

Sensitive, corrective, or difficult messages

Sincerely,
Respectfully,
Regards,
Thank you for your attention,
I appreciate your time,
Thank you for hearing me out,
I hope we can resolve this promptly,
I'm available to discuss,
Please let me know how you wish to proceed,

Keep a difficult ending calm and literal. “Respectfully” does not neutralize an accusatory body, and “Looking forward to your prompt response” can read as a threat. State the evidence, desired resolution, responsible party, and deadline without sarcasm. For legal, employment, safety, or regulatory matters, follow organizational policy and obtain appropriate review.

Professional sign-offs to use carefully

Thanks in advance: can imply agreement before the person has accepted the request. Use “Thank you for considering this” when the answer may reasonably be no.
ASAP: gives urgency but no usable deadline or context. Name the date, time, timezone, and consequence instead.
Cheers: ordinary in some regions and informal in others. Follow the recipient's tone when cultural context is uncertain.
Yours faithfully: appropriate in some formal conventions when the recipient is unnamed, but unusual in everyday US business email.
Sent from my phone: explains brevity but does not excuse unclear or careless writing. Remove an automatic footer if it adds no value.
No sign-off: efficient in a fast internal thread, but abrupt in first contact, a request, or a sensitive exchange.
Inspirational quotations: can distract, create accessibility noise, and imply organizational positions unrelated to the message.

A complete professional email ending

Could you approve option B by Thursday, August 6 at 3 p.m. ET?
If you need more time, reply with a date that works and I will adjust the launch plan.

The first line makes the desired action measurable. The second gives a safe alternative. The sign-off matches a professional client relationship, and the signature says who the sender is without repeating a banner, disclaimer, and multiple promotional links.

Frequently asked questions

What is the most professional email sign-off?

“Best regards” is a safe general choice. “Sincerely” is more formal, “Kind regards” is slightly warmer, and “Thank you” works when gratitude is warranted. The message's clarity and tone matter more than finding one universally perfect phrase.

Should I put a comma after an email sign-off?

A conventional sign-off is normally followed by a comma—“Best regards,”—then a line break and the sender's name. A full sentence such as “I look forward to speaking with you.” takes normal sentence punctuation instead.

Is “Best” too informal?

“Best” is widely used in everyday professional email, especially once a relationship exists. Choose “Best regards,” “Kind regards,” or “Sincerely” for more formal first contact or a context with stricter conventions.
