Professional Email Sign-Off: The Best Closings and When to Use Each
You have written the whole message, made your request, struck the right tone, and then the cursor blinks at the bottom of the screen. What now? “Best”? “Regards”? “Warmly”? “Cheers”? The professional email sign-off is one short line, yet it is the last thing your reader takes in, and it quietly colours how the entire message feels. Get it wrong and a careful, courteous email can end on a note that feels cold, presumptuous, or oddly casual.
This guide is about that closing line specifically, the valediction, not the signature block beneath it. We will cover the best professional sign-offs, when to reach for each, how the choice shifts between formal and friendly, how first contact differs from a follow-up, the closings worth avoiding, and the cultural and tone considerations that trip people up.
This article is part of our complete guide to business email hosting.
Key Takeaways
• A sign-off is the short valediction between your final sentence and your name; its job is to match the formality and warmth of the message above it, not to sound clever.
• “Best regards” is the near-universal safe choice for professional email; “Sincerely” reads more formal, and “Best” or “Thanks” suit warmer, established relationships.
• Choose your sign-off by the reader and the stakes, not by habit. First contact leans formal; an ongoing thread can relax; a follow-up should feel lighter than the original.
• Some sign-offs actively work against you, from no sign-off at all to over-familiar or gimmicky ones, and a few carry unintended tone across cultures.
• The word you pick sits on top of one thing you control completely: the address it comes from. A professional closing from [email protected] reads as more credible than any phrasing from a free generic account.
What is an email sign-off, exactly?
An email sign-off is the brief word or phrase you place on its own line after your final sentence and before your name. “Best regards,” “Sincerely,” “Thanks,” “Cheers” are all sign-offs. It is sometimes called a valediction or a complimentary close, and it is distinct from the closing line that precedes it and the signature block that follows it.
That distinction matters, because people often blame the wrong element when an ending feels off. The closing line (“I look forward to hearing from you”) points to what happens next; the signature confirms who you are; the sign-off simply bridges the two with a courteous handshake. It carries less literal meaning than either, which is precisely why it should never fight the tone of the message it caps. The goal is quiet appropriateness: when a sign-off draws attention, it is almost always because it clashes, and the best one is the one nobody remembers.
The best professional email sign-offs, and when to use each
Most professional email lives in the middle of the formality spectrum, which is why a handful of dependable sign-offs cover the vast majority of situations. The table below maps each common sign-off to its tone and the moments it fits best. Treat it as a guide, not a rulebook: your actual relationship with the reader always outranks a generic label, and context can nudge any of these up or down the scale.
| Sign-off | Tone / formality | When to use it |
|---|---|---|
| Sincerely | Formal | Cover letters, official correspondence, first contact with a senior or unknown person |
| Best regards | Semi-formal | The safe default for most business email: clients, prospects, colleagues you respect |
| Kind regards | Semi-formal, slightly warmer | Client and customer email, service replies, warm professional tone (common in UK and EU) |
| Regards | Semi-formal, neutral | Routine, efficient business email where warmth is not required |
| With appreciation / Many thanks | Semi-formal, grateful | When you are genuinely thanking the reader for time, help, or a decision |
| Best | Casual-professional | Colleagues, ongoing threads, contacts you already know |
| Thanks | Casual-professional | When there is a real request or genuine gratitude in the message |
| Cheers | Casual | Friendly peers, informal cultures, established relationships |
| Warm regards / Warmly | Warm | Thank-you notes, long relationships, a personal-professional blend |
| Talk soon / Speak soon | Casual, forward-looking | Ongoing relationships where a real next conversation is genuinely coming |
| Looking forward | Semi-formal, expectant | When you have proposed a next step and want to reinforce momentum |
A few of these deserve a closer word. “Best regards” is the safe default: polite without being stiff, warm without presuming familiarity, and almost impossible to misjudge. In our experience editing business correspondence across many industries, it is the closing that survives the widest range of readers with no friction. “Sincerely” carries the weight of the traditional business letter, right for a cover letter, an official or legal message, a complaint, or a first email to someone senior; in everyday email it can read as slightly distant, so reserve it for when formal distance genuinely fits. And once a relationship is established, a shorter close signals rapport: “Best” rarely feels wrong with colleagues, “Thanks” works when there is a genuine request or real gratitude but rings hollow when you have asked for nothing, and “Cheers” suits peers and informal cultures but is best avoided with strangers until you know the temperature of the exchange.
How the situation changes the right sign-off
Read the situation before you reach for a word. The same person can warrant different sign-offs from you depending on where you are in the relationship and what the message is doing.
Formal email
A formal email ending leans on restraint. Pair a courteous, forward-looking closing line with “Sincerely” or “Best regards,” and let the tone stay measured. Formality here is not coldness; it is appropriate distance for a relationship that has not yet earned warmth.
Thank you for your consideration. I look forward to your response.
Sincerely,
Friendly or ongoing email
When there is genuine rapport, you have room to sound human. “Best,” “Thanks,” or “Cheers” all work, paired with a relaxed closing line. Casual does not mean careless, though: even a quick note reads better when the final sentence points somewhere.
Let me know if that works on your end.
Best,
First contact
First contact is where people most often misjudge tone, usually by being too casual too soon. When you have never emailed someone before, default upward: “Best regards” is the floor for a cold professional message, and “Sincerely” suits a formal or senior recipient. Warmth is a privilege the relationship grants over time; opening with “Cheers” or “Talk soon” to a stranger can read as presumptuous, however friendly your intent.
Follow-up email
A follow-up should feel lighter than the message it chases, not a repeat of the same formal weight. If your first email closed with “Best regards,” a gentle nudge a few days later reads better with a softer, briefer close and a low-pressure closing line. The aim is to feel patient and easy, never demanding.
Just floating this back to the top of your inbox in case it slipped past. No rush at all.
Thanks,
Sign-offs to avoid
Some closings quietly undercut otherwise strong messages. A few to keep out of professional email:
- No sign-off at all. Ending with just your name, or nothing, can read as curt or rushed. A two-word close costs nothing and softens the landing.
- The hollow “Thanks” (and “Thanks in advance”). Thanking a reader when you have asked for nothing reads as a verbal tic; “thanks in advance” can feel like it assumes compliance before they have decided.
- Over-familiar closings to strangers. “Cheers,” “Talk soon,” “Hugs,” or “xoxo” to someone you have never met feel presumptuous. Earn warmth before you spend it.
- Gimmicky or jokey sign-offs. “Yours in productivity,” “Stay awesome,” and their cousins draw attention to the sign-off, which is exactly what a good one never does.
- Heavy abbreviation and shouting. “Rgds,” “Thx,” or “THANKS!!!” read as rushed, careless, or loud. Spell the words out, and let warmth come from word choice, not punctuation.
- A sombre sign-off on a routine note. “Yours faithfully” or “Respectfully” on a quick internal message feels oddly heavy and can read as sarcastic. Match the weight to the moment.
The thread running through all of these is mismatch. A sign-off fails when it does not fit the message above it, and succeeds when it disappears into the tone you have already set.
Cultural and tone considerations
Sign-offs do not read the same way everywhere, and a phrase that feels perfectly neutral to you can carry a different temperature elsewhere. A few things worth keeping in mind:
- Regional habits differ. “Kind regards” is standard, warm-professional in the UK and much of Europe, while some US readers reach more often for “Best.” “Cheers” is comfortably professional in the UK and Australia but reads as more distinctly casual in parts of the US.
- Formality norms vary. Business cultures across parts of Asia, the Middle East, and continental Europe often lean more formal in first contact than typical US or UK email, so defaulting up to “Best regards” or “Sincerely” across cultures is the safer bet.
- Idioms may not translate. Playful or highly colloquial sign-offs can confuse a non-native reader or land flatly in translation. Plain, standard closings travel best.
- Mirror your correspondent. If the other person has moved from “Best regards” to “Best” to just their first name over a thread, it is usually safe to follow their lead a step at a time.
The practical takeaway is simple: when in doubt across any line of culture, seniority, or unfamiliarity, choose the more formal, more universal option. You can always warm up later; walking back an over-familiar first impression is harder.
Why the address behind your sign-off matters more than the word
Here is the part most sign-off advice skips. You can agonise over “Best” versus “Regards” and it will change how your email lands by a hair. Meanwhile, the address your closing comes from shifts how the whole message is trusted before the reader has processed a single word of your careful valediction. A flawless “Kind regards” from a free, generic email address reads as smaller and less established than a plain “Regards” from [email protected]. If you invest effort anywhere in your closing, invest it there first.

Frequently asked questions
What is the best professional email sign-off? For most professional email, “Best regards” is the best all-round choice. It is polite without being stiff, works for clients, prospects, and colleagues, and almost never feels wrong. Step up to “Sincerely” for formal or first-contact situations with senior or unknown recipients, and relax to “Best” or “Thanks” once a relationship is established.
Is “Best regards” too formal for everyday email? No, it sits right in the professional sweet spot, neither stiff nor overly casual, and suits the majority of business messages. If it feels a touch formal for a close colleague, “Best” is the gentler step down and “Regards” alone is slightly cooler. It only feels off on a genuinely personal note, where a warmer close like “Warm regards” fits better.
Should a follow-up email use a different sign-off than the original? It helps to make a follow-up feel lighter than the message it chases. If your first email closed formally with “Best regards,” a gentle reminder a few days later reads better with a softer, briefer close such as “Thanks,” paired with a low-pressure closing line. The goal is to seem patient and easy to deal with, never demanding.
Which email sign-offs should I avoid at work? Avoid no sign-off at all, gimmicky or jokey closings, heavy abbreviations like “Rgds,” over-familiar phrases such as “Talk soon” or “xoxo” with people you have not met, and “Thanks” when your message contains no request or genuine gratitude. Each draws attention or creates a tone mismatch. The reliable move when unsure is a plain, standard close like “Best regards.”
Does the email address I send from affect how my sign-off is received? More than the wording itself does. A sign-off from an address on your own domain, like [email protected], reinforces credibility, while the same closing from a free generic account quietly undercuts it. Readers register the domain as a signal of a real operation before they consciously process your sign-off, which is why a domain-based address is the closing upgrade most worth making.
Conclusion
A professional email sign-off is a small thing that does quiet, consistent work. Its job is not to impress but to fit: to match the formality and warmth of the message above it so cleanly that the reader never pauses on it. “Best regards” will carry you through most situations, “Sincerely” handles the formal and first-contact moments, and warmer closes like “Best,” “Thanks,” and “Cheers” are earned as relationships deepen. Read the situation, avoid the closings that create mismatch, and default upward when culture or seniority is uncertain. And remember that the most credibility-shifting element of any closing is not a word at all, but the professional address on your own domain that it comes from. Get that right, and every sign-off you write lands a little stronger.
