16+ Other Ways to Say “Sincerely” (Formal, Informal & Professional Alternatives)

Last updated: 19 September 2026

If you’ve typed “Sincerely” at the bottom of an email for the hundredth time this month, you’re not alone. It’s the safe default, the word we reach for when we’re not sure what else fits. But “sincerely” isn’t always the right closing, and using it in every message — from a job application to a text-like message to a coworker — can actually make your writing feel flat or generic.

This guide walks through 16+ other ways to say sincerely, sorted by formality: formal, professional, and informal. You’ll learn exactly when each alternative works, when it doesn’t, and how native English speakers actually use these closings in real emails and letters. I’ve edited hundreds of student essays and business emails over the years, and the sign-off is one of the first things people get wrong — not because they pick a “bad” word, but because they pick a word that doesn’t match the room they’re in.

By the end, you’ll know how to close a formal letter, a business email, and a casual note without repeating the same word every time.

Why “Sincerely” Isn’t Always Your Best Choice

“Sincerely” works as a safe, neutral sign-off, but it can sound impersonal or even a little cold in certain contexts, especially in ongoing business relationships or creative industries.

The word itself comes from the Latin sincerus, meaning pure or genuine. As an adverb, it modifies how something is done — you write “sincerely” to signal that your words are honest, not just polite formality. That’s exactly why it fits a cover letter or a complaint email so well.

But here’s the catch. When a word gets used everywhere, it starts to lose its punch. I see this constantly when I review job applications: every single cover letter ends with “Sincerely,” and after the fifth one, it barely registers with the reader. Swapping it out for something more precise — “Respectfully” for a formal request, “Best” for a quick internal note — actually helps your message land.

There’s also a grammar detail worth knowing. In US English, the standard order is “Sincerely yours.” In UK English, it flips to “Yours sincerely.” Neither is wrong; they’re regional conventions, similar to how Americans write dates as month/day/year and the British write day/month/year.

Formal Alternatives to “Sincerely”

Formal alternatives to “sincerely” — like “Respectfully,” “Yours faithfully,” and “With respect” — suit legal letters, academic correspondence, government forms, and messages to people you’ve never met.

These closings carry weight. Use them when the relationship is hierarchical, official, or entirely new. A hiring manager reading your first email from you, a judge, a landlord, or a government office all fall into this category.

1. Respectfully

“Respectfully” signals deference and formality, and it’s a strong choice when you’re writing to someone in a position of authority — a professor, a manager several levels above you, or a public official.

Example: “Thank you for considering my request. Respectfully, Maria Chen.”

Avoid pairing it with a casual tone in the body of the message. The closing should match the register of everything above it, or it feels tacked on.

2. Yours Faithfully

This one is almost exclusively British. Use “Yours faithfully” when you’re writing a formal letter and you don’t know the recipient’s name — for example, if you opened with “Dear Sir or Madam.”

Example: “I look forward to your response. Yours faithfully, J. Whitfield.”

American readers rarely use this closing, and it can read as unusual or overly stiff in US business emails, so save it for UK-style correspondence.

3. With Kind Regards

A slightly warmer cousin of “Kind regards,” this phrase still keeps things buttoned-up. It works well for formal emails where you want to sound courteous without sounding stiff.

Example: “Please let me know if you need anything further. With kind regards, David Okafor.”

4. Yours Truly

“Yours truly” is common in the US for formal letters where you know the recipient’s name but the relationship is still professional and somewhat distant.

Example: “I appreciate your time and consideration. Yours truly, Alicia Reyes.”

Grammar note: like “yours sincerely,” this phrase uses the possessive pronoun “yours,” never “your’s” or “you’re” — a mistake I see surprisingly often in student writing.

5. With Utmost Respect

Reserve this for situations that call for real gravity — a formal complaint, a resignation letter, or correspondence with someone significantly senior to you. It’s more emphatic than plain “Respectfully.”

Example: “I hope you’ll consider this request carefully. With utmost respect, Thomas Lee.”

Professional Alternatives to “Sincerely”

Professional alternatives — such as “Best regards,” “Kind regards,” and “Warm regards” — fit standard workplace emails, client communication, and networking messages where you want to sound polished but not overly stiff.

This is the middle ground most people actually live in day to day. You’re not writing to a stranger, and you’re not texting a friend — you’re emailing a colleague, a client, or a new business contact.

6. Best Regards

Probably the most-used professional sign-off after “sincerely” itself. It’s neutral, warm enough, and works in nearly any workplace context.

Example: “Let me know if you have questions. Best regards, Priya Sharma.”

7. Kind Regards

Slightly gentler than “Best regards,” this one suits emails where you want to sound approachable — think client check-ins or a note to a new coworker.

Example: “Looking forward to working together. Kind regards, Sam Osei.”

8. Warm Regards

Use this when there’s already some relationship warmth — a returning client, a long-time colleague, or someone you’ve met in person.

Example: “Thanks again for your patience on this. Warm regards, Elena Petrova.”

9. Best

Short, modern, and increasingly common in fast-paced workplace email threads. It’s efficient without being rude.

Example: “Talk soon. Best, Jordan.”

One caution: “Best” alone can read as abrupt in a first message to someone new. It works better once a conversation is already underway.

10. Thank You

When your email is essentially a request or a favor, ending with “Thank you” instead of “Sincerely” reinforces gratitude and closes the loop naturally.

Example: “I’d really appreciate your feedback by Friday. Thank you, Marcus Bell.”

11. With Appreciation

A step up from a plain “Thank you,” this closing fits emails following an interview, a reference, or a favor someone did for you.

Example: “I’m grateful for your guidance on this project. With appreciation, Nadia Farouk.”

12. Looking Forward to Hearing From You

This works less as a traditional closing word and more as a full sentence before your name — common in follow-up emails and proposals where you’re expecting a reply.

Example: “Looking forward to hearing from you. Rachel Kim.”

Informal Alternatives to “Sincerely”

Informal alternatives — like “Cheers,” “Take care,” and “Talk soon” — belong in casual emails to friends, close colleagues, or anyone you already have an established, relaxed relationship with.

Using “Sincerely” with a close coworker or a friend can actually create unwanted distance. It signals formality where none is needed, which can come across as cold or even passive-aggressive in the wrong context.

13. Cheers

Very common in the UK, Australia, and increasingly in casual US workplaces. It works for quick, friendly emails between people who already know each other.

Example: “Catch you at the meeting. Cheers, Ollie.”

14. Take Care

A warm, low-key sign-off that suits personal emails or messages to a colleague you’re friendly with, especially if the topic touches on something personal (a sick day, a family update).

Example: “Hope you feel better soon. Take care, Jasmine.”

15. Talk Soon

Best for emails that end a conversation but imply more contact is coming — planning a call, coordinating a project, or catching up with a friend.

Example: “I’ll send the draft over tomorrow. Talk soon, Ben.”

16. Warmly

A friendly, gentle closing that works for both semi-formal and casual messages, particularly in industries like education, healthcare, or nonprofit work.

Example: “Thanks for making time for this. Warmly, Grace Nakamura.”

17. All the Best

Flexible and widely accepted, this closing sits comfortably between informal and semi-formal. It works for goodbyes, congratulations, and general well-wishing.

Example: “Wishing you luck with the new role. All the best, Diego Morales.”

Quick Reference Table

Sincerely Yours vs. Yours Sincerely: What’s the Difference?

“Sincerely yours” is the standard US word order, while “Yours sincerely” is the standard UK word order — the meaning is identical, but mixing regional conventions can look like an error to a careful reader.

A common mistake I catch again and again in editing: writers dropping the “s” and writing “Your sincerely.” That’s incorrect. The phrase always needs the possessive pronoun “yours,” not the possessive determiner “your,” because “yours” stands in for “I am yours sincerely,” a shortened, older form of a full sentence.

If you’re writing to a UK-based client, “Yours sincerely” (after “Dear Mr. Smith”) will read as natural and correct. If you’re writing to a US-based recruiter, “Sincerely” or “Sincerely yours” fits better. Neither choice is more “correct” globally — it’s a matter of regional convention, much like “colour” versus “color.”

Common Mistakes to Avoid

The most frequent errors with “sincerely” and its alternatives involve mismatched formality, incorrect punctuation, and confusing the possessive form “yours” with “your.”

• Punctuation: Always follow the closing with a comma — “Sincerely,” not “Sincerely.” Then start your name on the next line.
• Formality mismatch: Don’t close a casual internal Slack-style email with “With Utmost Respect.” It reads as sarcastic even when you don’t mean it that way.
• Overusing “yours”: “Your’s sincerely” is never correct. There is no apostrophe in “yours.”
• Repeating the greeting’s tone: If you opened with “Hi Sarah,” don’t close with “Yours Faithfully.” Match the opening and closing formality.
• Using “Best” too early: Save the short, casual “Best” for after you’ve built some rapport with the recipient, not your very first email.

Another Word for Sincerely in Email

If you want another word for “sincerely” in an email, the best alternative depends on how formal, friendly, or professional you want to sound. “Sincerely” is a traditional closing that works well in formal correspondence, but modern emails often use shorter and more natural sign-offs.

For a professional email, you can use Best regards, Kind regards, Regards, Best, or Respectfully. “Best regards” is a versatile choice for coworkers, clients, managers, and professional contacts. “Kind regards” sounds slightly warmer while remaining professional. “Regards” is simple and neutral, especially when you already have an established relationship with the recipient.

For a more relaxed workplace email, Best, Thanks, or All the best can feel more natural. If your email is specifically thanking someone, “Thank you” can work well as the closing because it connects directly with the purpose of the message.

The important point is to match the closing with the overall tone of your email. A highly formal business letter may still benefit from “Sincerely,” while a casual professional message may sound more natural with “Best” or “Kind regards.”

Another Word for Sincerely in a Love Letter

In a love letter, “sincerely” can sometimes sound too formal or business-like. If you are writing something romantic and personal, a warmer closing usually expresses emotion more naturally.

Depending on your relationship, you could use With all my love, Yours always, With love, Forever yours, Lovingly, All my heart, or Yours truly. Each one creates a slightly different feeling. “With all my love” sounds deeply affectionate, while “Yours always” suggests lasting devotion. “With love” is simple, natural, and suitable for many romantic letters.

If you want the ending to feel personal rather than overly dramatic, you can also close with a short heartfelt sentence before your name. For example, you might write that you are grateful for the person, that you are thinking of them, or that you look forward to seeing them again.

In a love letter, the most meaningful closing is usually the one that sounds like you. The goal is not to find the fanciest synonym for “sincerely,” but to choose words that honestly reflect your feelings and relationship.

Another Word for Sincerely Apologize

When saying “I sincerely apologize,” you have several alternatives depending on the level of formality and emotion you want to express. Common choices include I genuinely apologize, I truly apologize, I deeply apologize, I am truly sorry, and Please accept my sincere apologies.

For professional situations, “Please accept my sincere apologies” is polite and respectful. It works well when responding to a customer, colleague, client, or professional contact. “I sincerely regret the mistake” is another formal option when you want to acknowledge responsibility without sounding overly emotional.

For personal situations, “I’m truly sorry,” “I’m genuinely sorry,” or “I deeply regret what happened” may sound more natural. These expressions focus more on genuine emotion than formal wording.

The best apology is not simply about using a stronger synonym. A meaningful apology should clearly acknowledge what happened, take appropriate responsibility, and, when possible, explain what you will do to prevent the problem from happening again.

What to Say Instead of Sincerely to a Friend

When writing to a friend, “sincerely” can sound unnecessarily formal. Friendly messages usually benefit from a closing that feels warm, natural, and personal.

You can use Take care, Best, All the best, Talk soon, See you soon, Cheers, With love, or simply Your name. The right choice depends on how close you are and what kind of message you are sending.

“Take care” is friendly and caring without being overly emotional. “Talk soon” works naturally when you expect to continue the conversation. “Cheers” has a casual and cheerful tone, while “With love” can be appropriate for a very close friend or family member.

You can also skip a traditional sign-off completely. In a casual email or message, ending with a natural sentence and your name may feel more authentic than adding a formal closing.

Sincerely Yours Synonyms Formal

If you are looking for formal alternatives to “Sincerely yours,” several traditional and professional closings can work depending on the situation. Examples include Yours sincerely, Yours faithfully, Respectfully, Respectfully yours, Kind regards, Best regards, and Cordially.

“Yours sincerely” is commonly used in formal correspondence, particularly when you address the recipient by name. “Yours faithfully” is traditionally associated with letters that begin with a general greeting rather than the recipient’s name, although conventions vary by region and style guide.

“Respectfully” can be suitable when writing to someone in a position of authority or when the message requires a particularly respectful tone. “Kind regards” and “Best regards” are more common in modern professional emails and provide a balance between formality and warmth.

When choosing a formal closing, consider the relationship, purpose, and medium. A traditional business letter may call for a more formal sign-off, while a routine workplace email usually sounds better with a concise modern closing.

What to Say Instead of Sincerely to a Teacher

When writing to a teacher, professor, or instructor, you can choose a closing that is respectful without sounding excessively formal. Good alternatives include Best regards, Kind regards, Respectfully, Thank you, Best, and With appreciation.

“Thank you” is especially useful when your email involves a request, question, feedback, or appreciation. For example, if you are asking your teacher for clarification about an assignment, ending with “Thank you” creates a polite and appreciative tone.

“Best regards” is a safe professional choice for most school or university emails. “Kind regards” sounds slightly warmer while maintaining respect. “Respectfully” may be appropriate in particularly formal communication, although it can sound more serious than necessary for an everyday email.

The most important thing is to keep the entire message respectful. A professional greeting, clear explanation, polite request, and appropriate closing work together to create a positive impression.

Synonym for Sincerely at the End of a Letter

There are many alternatives to “sincerely” at the end of a letter, and the best choice depends on the relationship between the writer and recipient. For formal letters, options include Yours sincerely, Yours faithfully, Respectfully, and Cordially.

For professional but less formal correspondence, Best regards, Kind regards, Warm regards, Best wishes, and All the best are useful alternatives. These closings work particularly well in modern emails and workplace communication.

For personal letters, you might choose With love, Warmly, Take care, Affectionately, Yours always, or With best wishes. These options make the ending feel more personal and less business-like.

A good closing should feel consistent with the rest of the letter. If the letter is serious and formal, choose a respectful sign-off. If it is warm and personal, use language that reflects the relationship. There is no single replacement for “sincerely” that works perfectly in every situation.

Alternatives to Sincerely Informal

For informal emails, notes, and personal messages, you can replace “sincerely” with a more relaxed closing. Common alternatives include Best, Cheers, Take care, Talk soon, See you, All the best, Catch you later, Thanks, and Have a great day.

“Best” is short and friendly, making it useful when you want to keep an email simple. “Cheers” has a casual and upbeat feel, while “Take care” adds a little warmth. “Talk soon” is a natural choice when you expect another conversation.

If you are writing to someone you know well, you may not need a traditional sign-off at all. A simple closing sentence followed by your name can sound more natural than “Sincerely.”

The key is to choose an informal alternative that matches your relationship with the reader. A message to a close friend can be relaxed and personal, while an email to a coworker may still need a professional touch. Using the right closing helps your message sound genuine rather than overly formal or distant.

Final Thoughts

“Sincerely” means “in a sincere manner: in a way that is genuine, honest, or heartfelt” — and that root meaning is exactly why it still works as a reliable, respectful default.

But you don’t need to lean on it for every message you write. Pick your closing the same way you’d pick your opening line: based on who’s reading it, how well you know them, and what kind of relationship you’re building. A well-matched sign-off — formal, professional, or casual — tells the reader you thought about them specifically, not just about finishing the email.
