How to End an Email: Professional Sign-Offs, Examples, and the Closing That Lands Right
You spend real care on the opening line, the request, the tone, and then you reach the bottom of the message and freeze. “Best”? “Regards”? “Cheers”? “Warmly”? The closing of an email feels small, almost an afterthought, yet it is the last thing your reader sees, and it quietly shapes how the whole message feels. A good ending leaves the right impression. A clumsy one can undo a careful paragraph.
This guide covers exactly how to end an email with confidence: which sign-off suits which situation, how formal and casual closings differ, what your signature should carry, the mistakes that make a closing feel off, and ready-to-use examples for the contexts you actually write in. By the end you will never hover over that last line again.
Key Takeaways
• An email closing has three parts: a closing line, a sign-off word or phrase, and your signature. All three should match the formality of the message.
• “Best regards” is the safe, near-universal choice for professional email; “Sincerely” reads as more formal, and “Best” or “Thanks” suit warmer, ongoing relationships.
• Match your sign-off to the relationship and the stakes, not to a personal habit. The right closing is the one that fits the reader, not the one you always use.
• A clean signature on your own domain address ([email protected]) reinforces credibility far more than any clever sign-off ever will.
• Avoid no sign-off at all, overly casual closings to strangers, mismatched tone, and signatures crammed with quotes, images, or legal boilerplate.
Here is the thing almost nobody says out loud about email closings: the sign-off word matters far less than the consistency and the address behind it. People agonize over “Best” versus “Regards” as if the choice carries deep meaning. It rarely does. What your reader actually registers, often without noticing, is whether the whole closing feels coherent: a warm message that ends coldly jars, and a formal request that ends with “Cheers!” undercuts itself. Beyond that, the single most credibility-shifting element of any closing is not a word at all. It is the signature block and the domain in the address it sits on. A perfectly chosen “Kind regards” from a generic free address reads as smaller than a plain “Regards” from [email protected]. So spend less energy on the perfect word and more on a signature that is clean, consistent, and anchored to a domain you own. The word is the garnish. The signature is the meal.
What are the three parts of an email closing?
Every well-formed email ending has three distinct parts, and treating them separately is the easiest way to get all three right. Confusing them is where most awkward closings come from. Once you see the structure, choosing each piece becomes almost mechanical, and the whole ending starts to feel deliberate rather than improvised.
The closing line is the final sentence of your message body, before any sign-off. It signals the conversation is wrapping up and often sets up the next step: “Let me know if you have any questions,” or “I look forward to hearing from you.” This line does most of the emotional work. It tells the reader what you expect to happen next.
The sign-off is the short word or phrase on its own line: “Best regards,” “Sincerely,” “Thanks.” It bridges your message and your name. This is the part everyone fixates on, though it carries the least meaning of the three.
The signature is your name and the details beneath it: title, company, phone, and your email address on its domain. In professional contexts, this block is your calling card, and it deserves more attention than the sign-off above it.
A complete closing reads as a smooth descent: a closing line that points forward, a sign-off that matches the tone, and a signature that confirms who you are. When one of those is missing or mismatched, the whole ending feels unfinished.
Which email sign-off should you use, and when?
Choosing a sign-off comes down to two questions: how formal is the relationship, and how warm do you want to sound? Most professional email lands comfortably in the middle, which is why “Best regards” has become the reliable default for so many writers. It is polite without being stiff, and it almost never feels wrong.
The table below maps the most common sign-offs to their formality and best use. Treat it as a quick reference, not a rulebook. Context and your own relationship with the reader always win.
| Sign-off | Formality | Best for | Notes |
|---|---|---|---|
| Sincerely | Formal | Cover letters, formal letters, first contact with senior people | Traditional and correct, can feel distant in everyday email |
| Best regards | Semi-formal | Most business email, clients, colleagues you respect | The safest near-universal choice. Polite and professional |
| Kind regards | Semi-formal | Client and customer email, warm professional tone | Common in UK and EU business; slightly warmer than “Best regards” |
| Regards | Semi-formal | Routine business email, neutral tone | Efficient and safe, a touch cooler than “Best regards” |
| Best | Casual-professional | Colleagues, ongoing threads, people you know | Friendly and brief; fine once a relationship is established |
| Thanks / Thank you | Casual-professional | When you are genuinely asking for or acknowledging something | Use only when there is something to thank for, or it rings hollow |
| Cheers | Casual | Friendly colleagues, informal cultures, peers | Relaxed and warm; risky with strangers or senior contacts |
| Warmly / Warm wishes | Warm | Relationships, thank-you notes, personal-professional mix | Genuinely warm; can feel too intimate for cold contacts |
| Talk soon / Speak soon | Casual | Ongoing relationships with a real next conversation | Implies continuity; do not use if there is no next step |
Best regards vs Sincerely: which is right?
The short answer: use “Sincerely” when the relationship is formal or brand-new, and “Best regards” for almost everything else. “Sincerely” carries the weight of the traditional business letter, which makes it ideal for cover letters, official correspondence, and a first email to someone senior you have never met. It is correct, but in day-to-day email it can read as slightly stiff or impersonal.
“Best regards” has quietly become the modern professional standard precisely because it sits in the sweet spot. It is respectful enough for a client, relaxed enough for a colleague, and rarely misjudged. In our experience writing and editing professional correspondence, when someone is unsure, “Best regards” is almost always the safe call.
How do you end a formal email?
A formal email ending leans on restraint. Keep the closing line clear and courteous, choose a traditional sign-off, and let your full signature carry the details. The goal is to sound professional and respectful without warmth that the relationship has not yet earned. Formality is not coldness; it is appropriate distance.
For formal contexts, pair a forward-looking closing line with “Sincerely” or “Best regards,” then a complete signature. Here are a few examples you can adapt.

Thank you for your time and consideration. I look forward to your response.

Notice that the closing line does the heavy lifting. The sign-off stays simple, and the signature stays complete. For a job application or cover letter especially, “Sincerely” remains the convention, and a tidy signature with your contact details and a professional email address signals that you take the exchange seriously. If you are following up after no reply, a separate, lighter touch usually works better than repeating a formal close.
How do you end a casual or friendly email?
Casual email gives you room to sound human, but warmth still needs a floor of professionalism if there is any work context at all. The trick is to relax the sign-off without abandoning structure entirely. “Best,” “Thanks,” or “Cheers” all work, paired with a friendly closing line and a shorter signature, often just your first name.
Casual does not mean careless. Even a quick note to a colleague reads better with a closing line that points somewhere: “Let me know what you think,” or “Talk soon.” Here are examples that stay warm without slipping into sloppiness.
Casual closing examples:
Let me know if that works for you.
Thanks,
Margot
Looking forward to catching up next week.
Cheers,
Margot
Great chatting today, talk soon.
Best,

A small caution on “Thanks.” It only lands when there is genuinely something to thank the reader for. Tacking it onto a message where you have made no request can feel oddly transactional, almost like pre-thanking someone for a favour they have not agreed to. When in doubt, “Best” is the gentler default for a friendly professional note.
What does a good email signature include?
A strong signature is short, scannable, and consistent. It should answer “who is this and how do I reach them?” in a glance, nothing more. The most common mistake is overstuffing: quotes, banners, social icons, legal disclaimers, and a photo all competing for attention. Restraint reads as confidence. Clutter reads as noise.
For most professionals, a clean signature contains your name, your title and company, one reliable phone number, and your email address on its own domain. That is usually enough. Optional extras like a website or a single relevant link are fine when they serve the reader, not your ego.

The detail that quietly does the most work here is the address itself. A signature ending in [email protected] tells the reader you run a real, established operation. The same signature ending in a free generic address subtly undercuts everything above it. That is why a domain-based professional address is the credibility upgrade most worth making, and it costs less effort than people assume. For the full picture on naming and structuring those addresses, our sibling guide on professional email addresses is the place to start.
Should you change your signature for replies?
Yes, lighten it. A full signature on the first message is appropriate, but repeating the entire block on every reply in a thread becomes visual clutter fast. For ongoing exchanges, trim down to just your first name, or set up a short “reply” signature with name and one line. Many email clients let you save more than one signature for exactly this reason. Match the weight of your sign-off to where you are in the conversation.
What are the most common email-ending mistakes?
The most common mistakes are not exotic. They are small habits that quietly weaken otherwise good messages. Most come down to mismatch: a closing that does not fit the message above it, or a signature that works against the impression you want to make. Fix these few and your endings will land cleanly almost every time.
No sign-off at all. Ending a professional email with just your name, or nothing, can read as curt or rushed. A two-word sign-off costs you nothing and softens the close.
Mismatched tone. A warm, personal message that ends with a clipped “Regards” feels cold. A formal request that ends with “Cheers!” feels flippant. Let the sign-off echo the temperature of the message body.
Overly casual closings to strangers. “Cheers” or “Talk soon” to someone you have never met can feel presumptuous. With cold contacts, default to “Best regards” until the relationship warms.
The hollow “Thanks.” Thanking someone when you have asked for nothing reads as a verbal tic, or worse, as pressure. Reserve it for genuine gratitude or genuine requests.
A cluttered signature. Inspirational quotes, multiple phone numbers, large images, and long legal disclaimers bury the information that matters. Keep it lean.
A generic free address in a business signature. Nothing undercuts a polished closing faster than a free generic email ending where a domain-based address should be. It is the one mistake that contradicts everything else you did well.
How DarazHost helps your email closings land with credibility
The most polished sign-off in the world sits on top of one detail you control completely: the email address in your signature. DarazHost business email lets you put every address on your own professional domain ([email protected]), so a signature reading “[email protected]” quietly confirms a real, established operation rather than a free generic account. You can set up named mailboxes, role addresses, and clean, consistent signatures across a whole team, backed by strong spam filtering, proper authentication, and 24/7 support. When your closing line, your sign-off, and your signature all sit on a domain you own, the impression is coherent from the first word to the last. That coherence, more than any single sign-off, is what makes an email ending feel genuinely professional.
Frequently asked questions
What is the best way to end a professional email? For most professional email, “Best regards” followed by your name and a clean signature is the safest, most reliable close. It is polite without being stiff and rarely feels wrong. Reserve “Sincerely” for formal or first-contact situations, and warmer sign-offs like “Best” or “Thanks” for relationships you have already established.
Is “Best regards” too formal or just right? “Best regards” is the modern professional sweet spot, neither too formal nor too casual. It works for clients, colleagues, and most business correspondence. If anything, it errs slightly toward polite, which is exactly where you want to be when unsure. “Regards” alone is a touch cooler, and “Best” is the warmer, more familiar option.
Should I always include a signature when ending an email? On a first message or any formal email, yes. A signature with your name, title, and a domain-based email address confirms who you are and how to reach you. On ongoing replies within a thread, trim it down to just your first name to avoid clutter. Match the signature’s weight to where you are in the conversation.
Can I use “Cheers” in a work email? Yes, but selectively. “Cheers” works well with colleagues you know, peers, and informal company cultures. It can feel too relaxed with senior contacts, clients, or anyone you are emailing for the first time. When the relationship or stakes are uncertain, default to “Best regards” and save “Cheers” for warmer, established exchanges.
Does the email address in my signature really matter for the closing? More than the sign-off word does. A clean address on your own domain ([email protected]) reinforces credibility, while a free generic address quietly undercuts an otherwise polished closing. Of every element in an email ending, the domain behind your signature is the one most worth investing in, because it shapes trust before the reader processes a single word.
