How to End an Email Professionally: 20+ Closings That Work

Most professionals spend significant time crafting the body of an email, then attach a reflexive “Best” and hit send without thinking twice. But knowing how to end an email professionally is just as important as the subject line and the opening — it’s the last thing your reader sees, and it shapes everything that follows: whether they reply, how quickly, and how they feel about working with you. A well-written email that closes awkwardly loses points it didn’t have to lose. For the broader framework this sits inside, see our guide to business English writing.

The Two Parts Every Professional Email Closing Needs

Most closing mistakes happen because writers treat the sign-off as a single decision. It’s actually two distinct components that need to work together.

The last line is the final sentence of your message body. It signals what happens next — a specific ask, a next step, or a graceful close to the conversation.

The sign-off is the one- or two-word phrase before your name: “Best,” “Kind regards,” “Thanks.” These two parts work as a unit. A warm sign-off after a cold, transactional final line creates dissonance. A formal sign-off after a friendly, casual exchange reads as oddly stiff. The examples in this guide pair them together, because that’s how readers experience them.

How to End an Email Professionally in Formal Situations

Use formal closings when writing to senior stakeholders you don’t know well, clients at first contact, or any situation where a tone error carries real professional risk.

Please do not hesitate to contact me should you have any questions.
Sincerely,

I look forward to your response at your earliest convenience.
Respectfully,

Thank you for your time and consideration on this matter.
Kind regards,

Should you require any further information, I remain available.
Yours faithfully,

One note on “Yours faithfully”: use it only when you have not used the recipient’s name in the greeting. If you opened with “Dear Mr. Chen,” close with “Yours sincerely” or “Kind regards.” If you opened with “Dear Sir or Madam,” “Yours faithfully” is technically correct. This is a British English convention, but it carries into international business correspondence.

What makes these closings work: complete sentences, no contractions, polished rather than stiff language. They signal professionalism without servility.

How to End an Email Professionally with Colleagues and Regular Contacts

Internal emails, regular contacts, and business relationships where rapport already exists call for a different register. Overly formal closings in these contexts read as cold or even passive-aggressive — the opposite of the professional effect you’re going for.

Let me know if you run into any questions.
Best,

Happy to hop on a call if that’s easier.
Thanks,

Looking forward to seeing where this goes.
Cheers,

Thanks again for your help on this — really appreciated.
Warmly,

“Warmly” gets unfairly dismissed in professional writing guides. It reads as genuine in most business contexts and sidesteps the overuse problem that makes “Best” feel generic. “Cheers” works well in tech and international environments but can feel too casual in traditional US corporate or legal settings — read the room before using it.

How to End an Email Professionally in Follow-Up Situations

Follow-up emails have a unique closing challenge. You need to prompt action without sounding impatient or desperate. The trick is making the next step explicit while keeping the tone easy and pressure-free.

I know schedules get busy — just let me know if the timing has shifted on your end.
Thanks,

Happy to provide any additional context that would help move this forward.
Best,

Feel free to reach out whenever works for you — I’m flexible on timing.
Looking forward to connecting,

Just wanted to make sure this didn’t get buried. No rush — let me know when convenient.
Best,

Closing a Request Email

Request emails need a closing that makes the ask easy to respond to without over-apologizing for having made the request.

Wrong:

I know you’re super busy and I’m so sorry to bother you, but no pressure at all, whenever you get a chance is completely fine!
Best,

Right:

Please let me know by Thursday whether this works — I want to finalize the schedule before the end of the week.
Thanks in advance,

“Thanks in advance” is underrated for request emails. It assumes cooperation without demanding it, and it creates a light social expectation that nudges the reader toward responding. Use it when the request is reasonable and you’ve given a clear timeline. The closing does work the body alone can’t.

Closing an Apology or Correction Email

Apology emails need a closing that acknowledges the issue without over-dramatizing it. Excessive apology in the closing — after you’ve already apologized in the body — reads as anxious rather than professional and actually draws more attention to the mistake.

Please don’t hesitate to reach out if there’s anything else I can do to address this.
Apologies again for the confusion,

I’m confident this won’t happen again, and I appreciate your patience.
With apologies,

Thanks for flagging this. I’ve made the correction and attached the updated version.
Best,

Notice the last example uses “Best” without a formal apology sign-off. Once the issue is fully acknowledged in the body, a normal sign-off is often the cleanest choice. Repeating the apology in the closing can signal that you’re still processing the mistake rather than moving forward — which is not the impression you want to leave.

What About “Best Regards”? The Honest Answer

“Best regards” is professional, inoffensive, and entirely correct. It is also so widely used that it has become effectively neutral — neither warm nor formal, just expected background noise.

That’s not a reason to avoid it. If your goal is a versatile sign-off that won’t put a foot wrong in any context, “Best regards” is exactly right. Whether to use something more specific depends entirely on whether you want the closing to actively reinforce the tone of your message — friendly, decisive, warm.

The more interesting comparison is “Best regards” versus “Best” on its own. “Best” reads as modern and slightly warmer. “Best regards” carries a touch more formality. Both are entirely correct. The debate that occupies some writing guides is not worth the energy it consumes — pick the one that fits your relationship and move on.

Sign-Offs That Undermine Professional Email

“Regards,” alone — curt in most US contexts. Fine in British professional culture; can read as cold or passive-aggressive in American business email.

“Thanks!” with an exclamation point — the exclamation mark undermines the gratitude it’s meant to convey. It reads as performative rather than genuine.

“Yours truly,” — dated. Reserve it for very formal legal or government correspondence only.

Nothing at all, just your name — works in rapid internal back-and-forth threads once a relationship is established. Feels abrupt for first contact or anything requiring thought.

“Sent from my iPhone” — not a sign-off. Delete this from important emails. It signals a lack of attention to detail in messages that clearly required real effort to write.

Why the Closing Reveals More Than Most Writers Realize

This is where a tool like NotchTutor’s English writing assistant surfaces something other tools miss. Writers who struggle with register — matching the formality level to the audience and context — often make that mismatch most visible at the very end of their emails. A strong pitch that closes with a breezy “Talk soon!” to a board member. An excellent internal update that ends with “Respectfully yours” to a teammate.

NotchTutor checks tone and register patterns across the full message, including the closing, and flags when your sign-off is out of step with the formality of what preceded it. The explanation tells you why the mismatch creates friction for a reader — which means you can avoid the same problem in the next email without checking a reference guide. Pattern recognition across your writing, not just a one-time flag.

Quick Reference: Email Closing by Situation

Information-only message, no reply needed:

No reply necessary — just keeping you in the loop. Best,

Your email closing is three to six words. But those words carry the tone of everything that came before them, and they determine the last impression you leave. Getting them right costs you nothing and can shift how a message lands significantly.
