Every Email Sign-Off Ranked: From "Best" to "Cheers" to "Regards"
Email sign-offs ranked by professionalism, warmth, and context-appropriateness — so you can stop defaulting to "Best" and choose the right closing every time.
“Best regards” is the safest professional email sign-off in most contexts. “Thanks” is warmer and appropriate for requests. “Cheers” is British-casual and fine internally but informal externally. “Yours sincerely” is formal and correct for first contact in British English. “Best wishes” is slightly more personal than “regards” but less formal than “sincerely.” Below is the full ranking from most formal to most casual, with notes on when each one is appropriate.
Why the Sign-Off Matters
The last thing your reader sees in an email is the sign-off. It leaves a tone impression that lingers after the content has been processed. A mismatch — “Warmly” on a formal complaint, or “Yours faithfully” on a quick Slack-adjacent note — creates small friction that accumulates over time.
For non-native speakers, sign-offs are also an area where cultural norms carry over incorrectly. “With deep respect” is the correct translation of some formal closings in German, Spanish, or Chinese — but in English, it’s odd. Knowing the actual range of English sign-offs gives you confidence to choose deliberately.
The Full Ranking (Most Formal → Most Casual)
Tier 1: Formal (Use for official letters, first contact with senior figures, legal or HR communications)
Yours faithfully Used in British English when you’ve addressed the email “Dear Sir/Madam” (i.e., you don’t know the person’s name). Almost never used in American English. Correct and appropriate in formal British business contexts.
Yours sincerely British English sign-off when you’ve used the person’s name (“Dear Ms. Thompson”). American equivalent would be “Sincerely.” Both are appropriate for first contact with senior figures, formal business proposals, or any written communication that might be kept on record.
Sincerely Standard formal American English. Safe, appropriate, slightly cold for anything beyond a formal introduction. In the UK, “Sincerely” without “Yours” sounds slightly clipped — prefer “Yours sincerely.”
Tier 2: Professional (The everyday sweet spot for most professional email)
Kind regards Warm, professional, and widely used. Slightly more personal than “Best regards” without being casual. Works well for ongoing correspondence, client communication, and emails to colleagues you’ve spoken with before.
Best regards The safe default for professional email globally. Neither warm nor cold. Universally understood. If you’re not sure what to use, this works.
With best regards Slightly more formal and warm than “Best regards.” Common in European business English. Americans use it less frequently, but it’s understood everywhere.
Regards Professional but slightly abrupt. Fine for routine communication; can read as slightly brusque in more formal or emotionally sensitive contexts. Avoid it when you need warmth.
Tier 3: Professional-Warm (Good for colleagues and clients you know)
Best wishes Warmer than “regards” variants, carries a personal touch. Appropriate for end-of-project messages, holiday-adjacent emails, or correspondence with clients you have a genuine relationship with.
Many thanks Appropriate when you’ve made a significant request or the person has done something genuinely helpful. More emphatic than “Thanks.”
Thanks Warm and appropriate for most request-response exchanges. Overused as a default, but not wrong. If someone does something for you and you sign off with “Thanks,” that’s correct.
Thank you Slightly more formal than “Thanks” — the distinction is minimal but noticeable. Use “Thank you” in slightly more formal contexts where “Thanks” might read too casual.
Tier 4: Casual-Professional (Internal team emails, colleagues you talk to daily)
Best An American classic. Short, clean, professional-casual. Appropriate for colleagues you interact with regularly. In Europe, “Best” without “regards” or “wishes” sounds incomplete to some readers — “Best regards” or “Kind regards” is safer for cross-cultural use.
All the best Warm and send-off-appropriate. Works well as a final email in a project, or when signing off on a longer relationship. Not suitable for routine operational emails.
Cheers British and Australian casual. Entirely appropriate in UK/Irish workplaces for internal email. Reads as too casual for formal external correspondence, first contact with senior figures, or communications in countries where “cheers” isn’t natural.
Tier 5: Very Casual (Internal only, close colleagues)
Take care Personal and warm. Fine for close colleagues or end-of-project emails. Inappropriate for external correspondence or formal contexts.
Talk soon / Speak soon Implies imminent further contact. Only use if you’re actually going to talk to this person soon.
Have a good one Very casual American English. Fine for quick messages to close team members; inappropriate for clients, executives, or external contacts.
The Sign-Offs to Avoid
No sign-off at all: Abrupt. In a long email thread, dropping the sign-off is common and fine. In a standalone email or first contact, it reads as rude or hasty.
Warmly: Overly personal for most business contexts. Sounds appropriate for a newsletter or personal email; strange in a client email or professional request.
Respectfully: Sounds like you’re making a formal submission or end of a legal letter. In most workplace email contexts, it reads as overly stiff or quasi-legal.
Yours truly: Dated American English. Hasn’t been common in business writing since the 1980s.
With deep respect / With all due respect: Not natural English email closings. Direct translations from other languages that don’t fit English conventions.

FAQ
Is “Best” too casual for client emails?
In American professional culture, “Best” is widely accepted for client email, even first contact. In British and European contexts, “Best regards” or “Kind regards” is safer. When in doubt, add “regards.”
What should I use for a job application?
“Yours sincerely” (British English, formal) or “Sincerely” (American English). These are the appropriate closings for a formal letter or email where you’re trying to make a professional impression on a new contact.
Can I use different sign-offs with the same person?
Yes. Varying your sign-off based on context is natural. “Thanks” for a request response, “Best wishes” at the end of a project, “Kind regards” for a formal update — mixing appropriately is better than using the same one mechanically every time.
What’s wrong with “Hoping to hear from you soon”?
Nothing grammatically, but it implies expectation and can feel slightly pressuring. “I look forward to hearing from you” is the standard professional version. “Please let me know if you have questions” is even better because it puts agency with the reader.
Should non-native speakers use casual sign-offs?
Start with the safe professional middle range (Kind regards, Best regards, Thanks) until you have a good read on your company culture. Once you see what colleagues use, you can calibrate. Don’t start with “Cheers” if you’re not sure it’s appropriate in your context.
