Knowing how to end an email well comes down to one rule: match the sign off to your relationship with the reader and the nature of your ask. A formal request needs a formal close, while a note to a colleague can be warmer. The wrong sign off can feel cold, too casual, or even passive aggressive. This guide gives you over forty sign offs grouped by situation, the ones to avoid, how to write the closing line, and brief cultural notes.
40 plus sign offs by situation
Here are sign offs grouped by the situation you are writing in. Pick one that fits your relationship and tone.
Formal business
Best regards, Kind regards, Regards, Yours sincerely, Respectfully, With appreciation, Sincerely.
Guidance: Use these with people you do not know well, senior contacts, or official messages. Best regards and Kind regards are safe, professional defaults that work almost anywhere.
Friendly professional
Thanks, Cheers, All the best, Best, Take care, Warm wishes, Talk soon.
Guidance: Use these with colleagues and contacts you have a rapport with. They keep things professional while feeling human, and Thanks is a friendly, everyday choice.
Follow ups
Looking forward to your reply, Following up, Appreciate your time, Awaiting your thoughts, Hope to hear from you.
Guidance: These gently signal you are expecting a response without pressure. Pair them with a short, polite reminder of your original request so the reader knows what to do.
Asking for something
Thank you in advance, With thanks, Grateful for your help, Thanks so much, Much appreciated.
Guidance: When you need a favor or action, a thankful close acknowledges the effort you are asking for. Keep it genuine, since overusing thanks in advance can feel presumptuous to some readers.
Apologies
With sincere apologies, Thank you for your understanding, Apologies again, Sorry for the inconvenience.
Guidance: When you are apologizing, the close should reinforce accountability and appreciation for the reader’s patience. Keep the tone sincere and avoid anything that sounds flippant.
Cold outreach
Thanks for your time, Best regards, Looking forward to connecting, Appreciate your consideration, No worries either way.
Guidance: With someone who does not know you, be polite, low pressure, and respectful of their time. No worries either way is a friendly way to lower the stakes and improve replies.
Job search and interview sign offs
This is the situation where the sign off carries the most weight and where a wrong choice is most visible, so it is worth treating separately from ordinary business mail. In every case below, the closing line does the work and the sign off simply lands it.
Sending an application or cover letter. Closing line: “Thank you for considering my application.” Sign off: Sincerely, This is the one context where Sincerely still reads as correct rather than stiff, because you are writing to someone you have never met about a formal process.
Replying to an interview invitation. Closing line: “Thank you, I look forward to speaking with you on Thursday.” Sign off: Best regards, Repeat the agreed day back to them; it confirms the slot without a second email.
After a phone screen or first interview. Closing line: “I appreciate your time today, and the role sounds like a strong fit.” Sign off: Best regards, Send it the same day. The sign off matters far less than the timing.
Following up when you have heard nothing. Closing line: “I wanted to check in on the timeline, and I remain very interested.” Sign off: Many thanks, Avoid anything that reads as impatient. “Just following up” in the closing line is the part that stings, not the sign off.
Accepting an offer. Closing line: “I am delighted to accept, and I am looking forward to joining the team.” Sign off: Sincerely, or With thanks, Warmth is appropriate here in a way it is not earlier in the process.
Declining an offer. Closing line: “Thank you for the offer and for the time your team gave me.” Sign off: Best wishes, Keep it short and warm. You may well apply there again.
Networking or asking for an introduction. Closing line: “No obligation at all if the timing is wrong.” Sign off: Best, Giving the person an easy exit is what gets replies from strangers.
Sign offs to avoid and why
Some sign offs work against you, so it helps to know which to skip. Overly casual closes like Later, Ciao, or an abrupt Yo can undermine a professional message, especially with people you do not know well, so save them for genuine friends. Outdated or overly stiff options like Yours faithfully can feel oddly formal in most modern business email unless the context is truly official.
Watch out for sign offs that can read as passive aggressive: a curt Regards after a tense exchange, or Per my last email, can come across as cold or pointed even if you did not mean it that way. Avoid religious or overly personal closes in professional settings unless you know they are welcome. And never leave no sign off at all on a formal message, since it can feel abrupt.
The safe path is to match the tone to the relationship, lean on professional defaults when unsure, and reread your close to check it does not carry an unintended edge.
The punctuation and capitalisation rules
Two small mechanics that a lot of otherwise careful writers get wrong, and both are visible at a glance.
Capitalise only the first word. It is Best regards, not Best Regards. Kind regards, not Kind Regards. Yours sincerely, not Yours Sincerely. A complimentary close is treated like the end of a sentence, so the first word takes the capital and the rest stay lowercase. This is described by style guides as one of the most common capitalisation errors in professional email, which is exactly why it is worth fixing: plenty of your readers will not notice, and the ones who do will notice every time.
Put a comma after it. The sign off sits on its own line, ends with a comma, then your name goes on the next line:
Best regards, Priya Sharma
No comma at all reads as abrupt. A full stop is wrong. An exclamation mark makes a formal close sound like a birthday card.
One exception worth knowing: if your sign off is a complete sentence, such as “Looking forward to hearing from you,” it still takes the comma, but it should not also be doing the job of your closing line. Pick one or the other, not both.
The closing line before the sign off
The sign off is only half the ending; the sentence just before it often matters more. A strong closing line makes your purpose clear and tells the reader what happens next. If you want a reply, say so simply, such as asking them to let you know their thoughts by a certain time.
If you want an action, state it clearly and politely, like asking them to confirm or send something. If you are wrapping up, a brief thanks or a friendly note works well. The pattern is to end the body with one clear, courteous call to action, then follow it with a fitting sign off and your name.
For example, a line inviting their reply, followed by Best regards and your name, reads as complete and professional. Avoid ending on a vague note that leaves the reader unsure what you want, since a clear closing line is what turns a good email into one that gets a response.
Cultural notes for international email
Email norms differ across cultures, so a little awareness helps when writing internationally. Some cultures favor more formal, elaborate closings and titles, while others, particularly in much of the English speaking business world, lean toward brief, friendly sign offs. When in doubt with an international contact, start more formal and mirror their style as the exchange continues, since matching the other person’s tone is usually welcome.
Be mindful that directness and warmth are read differently across regions, so a close that feels normal to you might seem too casual or too stiff elsewhere. You do not need to master every custom; simply defaulting to a polite, professional close like Best regards, and paying attention to how your contact signs off, will serve you well across most cultures. When a relationship spans languages, erring slightly on the side of formality early on is rarely a mistake, since it is easier to relax a tone than to recover from one that landed as too casual.
Adapting gently as you learn the person’s preference is the practical approach.
Verdict
Ending an email well is simple once you match the sign off to the relationship and the ask. Use formal closes like Best regards for people you do not know, warmer ones like Thanks for colleagues, and thankful closes when you need a favor. Avoid overly casual, outdated, or unintentionally cold sign offs, write a clear closing line that says what you want next, and adjust gently for international contacts.
Keep a few reliable defaults in mind, and you will close every email on the right note without overthinking it. The safest habit is to pick your sign off based on who is reading and what you are asking, reread it once to catch any unintended tone, and let a simple professional close do its job.

Frequently asked questions
What is the most professional email sign off?
Best regards and Kind regards are widely considered the most reliable professional sign offs, since they are polite, appropriate for almost any business context, and rarely misread. Sincerely and Regards also work well for formal messages. When you are unsure of the right tone, Best regards is a safe default that strikes the balance between professional and approachable in nearly every situation.
Is Best regards too formal?
No, Best regards is not too formal for most professional email; it is one of the safest, most versatile closes. It works with new contacts, colleagues, and clients alike, reading as polite and professional without being stiff. If you have a warm rapport with someone, you might choose something friendlier like Thanks or Best, but Best regards is rarely, if ever, the wrong choice.
How do you end an email asking for something?
When asking for something, end with a clear, polite closing line stating your request, followed by a thankful sign off such as Thank you in advance, With thanks, or Grateful for your help. This acknowledges the effort you are asking for and encourages a response. Keep the request specific and the tone genuine, and make it easy for the reader to know exactly what you need.
Is Thanks a good sign off?
Yes, Thanks is a good, friendly sign off for everyday professional email, especially with colleagues and contacts you know. It feels warm and human while staying professional. For more formal messages or unfamiliar recipients, Best regards may fit better. Thanks works particularly well when you are genuinely grateful or making a small request, so it is a useful everyday option in your toolkit.
Is it Best Regards or Best regards?
Best regards, with a lowercase r. A complimentary close is capitalised like the start of a sentence, so only the first word takes a capital and the rest stay lowercase. The same applies to Kind regards and Yours sincerely. Style guides call this one of the most common capitalisation mistakes in professional email.
Do you put a comma after the sign off?
Yes. The sign off goes on its own line and ends with a comma, then your name on the next line. Leaving it out reads as abrupt, a full stop is incorrect, and an exclamation mark undercuts a formal close.
How do you end an email after a job interview?
Thank them for their time, say something specific about the role, and close with Best regards. For example: I appreciate your time today, and the role sounds like a strong fit. Best regards, followed by your name. Send it the same day, since timing matters more here than the sign off you pick.
