How to End an Email Professionally (Closings, Sign-Offs & Examples)

How you end an email matters more than most people realize. The closing is the last thing the recipient reads, and it shapes their final impression of the email - and of you. A strong ending reinforces your message, makes the next step clear, and leaves the reader feeling respected. A weak ending creates ambiguity, undermines your professionalism, or simply fizzles out without impact.

The right email closing depends on three factors: your relationship with the recipient, the formality of the situation, and what you want to happen next. This guide covers the closings, sign-offs, and final sentences that work for every professional situation.

Why Your Email Closing Matters More Than You Think

Most people spend time crafting their email's opening and body, then slap on a "Best," without much thought. But research on effective communication shows that people remember the beginning and end of any message most clearly - a phenomenon psychologists call the primacy and recency effects.

Your closing is your final opportunity to:

• Reinforce your key message - summarize what you need in one sentence
• Set the tone for the reply - a warm closing invites a warm response
• Demonstrate professionalism - or undermine it with a sloppy sign-off
• Prompt specific action - the last line is the most likely to trigger a response

If you're working on your overall email writing skills, our comprehensive guide on how to write a professional email covers every element from subject lines to signatures.

Professional Email Closings by Formality

Formal Closings

Use these when emailing executives, clients you don't know well, government officials, or in any situation where professionalism and respect are paramount.

• Sincerely, - The most universally appropriate formal closing. Safe in every professional context. Use this as your default when you're unsure.
• Respectfully, - Appropriate when writing to someone senior to you or in a position of authority. Common in government, military, and academic correspondence.
• Best regards, - Slightly warmer than "Sincerely" while maintaining full professionalism. The most popular formal closing in business email.
• Kind regards, - A touch warmer than "Best regards." Popular in international business communication, especially in European and Asian business cultures.
• With appreciation, - Use when the email involves gratitude or when the recipient has done something for you. More genuine than a generic "Thanks."
• Respectfully yours, - Very formal. Appropriate for official correspondence, legal matters, or cultural contexts that value high formality.
• Cordially, - Formal but with warmth. Commonly used in diplomatic and academic correspondence.
• With gratitude, - When the recipient has gone above and beyond. Stronger than "With appreciation" and appropriate when you want to express deep thanks.

When to use formal closings:

• First email to a new client or prospect
• Job applications and cover letters
• Communication with C-suite executives
• Legal, regulatory, or government correspondence
• Cross-cultural business communication where you're unsure of norms
• Any email where you're representing your company externally

Standard Professional Closings

Use these for most workplace communication - colleagues, business partners, clients with established relationships, and professional contacts.

• Best, - The workhorse of professional email closings. Professional without being stiff, appropriate in nearly every business context.
• Thanks, - When the email involves a request or when you're genuinely grateful. Short, warm, and universally appropriate.
• Thank you, - Slightly more formal than "Thanks," appropriate when expressing genuine gratitude.
• Regards, - Professional and neutral. Some find it slightly cold, but it's perfectly appropriate.
• All the best, - Warm and professional. Good for closing emails with a personal touch.
• Looking forward to hearing from you, - When you're expecting a response. Works as both a closing line and a sign-off.
• Talk soon, - For people you'll communicate with again soon. Casual but professional.
• Many thanks, - Warmer than "Thanks" but not as formal as "With appreciation." Works well in British and international English.
• With thanks, - A slightly more formal version of "Thanks" that feels more considered.

When to use standard closings:

• Day-to-day emails with colleagues
• Ongoing client communications
• Follow-ups and check-ins
• Internal team updates
• Emails to professional peers in your industry

Casual Professional Closings

Use these for colleagues you work with daily, team members, or professional contacts with an established casual relationship.

• Cheers, - Popular in certain workplaces and cultures (especially UK, Australia). Check your workplace culture before using.
• Take care, - Warm and friendly. Appropriate when closing a more personal professional conversation.
• Have a great weekend, - When sending a Friday email. Adds a human touch to routine communication.
• Enjoy the rest of your day, - Similar warmth, works any day of the week.
• Chat soon, - Very casual. Only for close colleagues or established informal relationships.
• Until next time, - Works well when you have regular scheduled communication with someone.
• Happy [day of the week], - Light and friendly. "Happy Friday" on a Friday afternoon email feels natural.

When casual closings work:

• Internal team chat
• Follow-up emails after casual in-person conversations
• Colleagues you interact with daily
• After several rounds of back-and-forth in a casual thread

Email Sign-Off Formality Table

How to Write the Last Sentence Before Your Closing

The final sentence of your email is as important as the sign-off. It should either summarize the action you need, express gratitude, or provide a clear next step. Think of it as the bridge between your email's content and your sign-off.

When You Need a Response

• "I'd appreciate your input by Friday so we can finalize the plan."
• "Could you confirm your availability for any of the times I suggested?"
• "Please let me know if you have any questions about the proposal."
• "A quick yes or no by Thursday would help us stay on schedule."
• "Would Tuesday or Wednesday work better for a 15-minute call?"

The key is specificity. "Let me know" is vague. "Let me know which option you'd prefer by end of day Thursday" gives the recipient a clear task with a clear deadline.

Final Sentence CTA Table

When You're Providing Information

• "I hope this helps - feel free to reach out if you need any clarification."
• "Let me know if you'd like me to go into more detail on any of these points."
• "I'm happy to discuss further if that would be useful."
• "The full report is attached - the key findings are on pages 3-5."
• "No action needed on your end - just wanted to keep you informed."

When You're Expressing Gratitude

• "Thank you for taking the time to review this thoroughly."
• "I really appreciate your help with this - it made a significant difference."
• "Thanks again for your flexibility on the timeline."
• "Your feedback was invaluable - it changed our approach for the better."
• "I'm grateful for your quick turnaround on this."

When You're Wrapping Up a Project or Thread

• "I think we're in great shape - nice work, everyone."
• "Looking forward to seeing the final results."
• "Thanks for a productive meeting - I'll send the recap this afternoon."
• "Great collaboration on this - looking forward to the next one."
• "This wraps up Phase 1 - I'll kick off Phase 2 planning next week."

When You're Writing a Difficult or Sensitive Email

• "I appreciate your understanding on this matter."
• "I know this isn't the answer you were hoping for, and I'm sorry I can't be more helpful."
• "I respect your position on this, and I'm open to finding a solution that works for both sides."
• "Thank you for your patience while we worked through this."

Closings to Avoid

"Sent from my iPhone" - This isn't a closing; it's an excuse for typos. Either remove the default signature or replace it with a proper sign-off. Leaving it as your only closing looks careless.

No closing at all - Ending an email abruptly with no sign-off feels cold, even in casual workplaces. Even a simple "Thanks" is better than nothing.

"Best" followed by nothing - Include your name after your closing. A sign-off without a name feels incomplete.

"Thx" or "Ty" - Text abbreviations have no place in professional email. Take the extra second to type "Thanks."

"Warm regards" - This is debated. Some find it perfectly professional; others find it oddly intimate for a work context. If you're unsure, stick with "Best regards."

"Looking forward to your response" (when it's passive-aggressive) - This closing is fine when you're genuinely anticipating a reply. It's not fine when you're using it to pressure someone who hasn't responded.

"Please do the needful" - While common in some regions, this phrase is often perceived as awkward or overly formal in American and European business contexts. Use "Please let me know if you need anything else" instead.

"Thanks in advance" - Some people find this presumptuous because it assumes the recipient will do what you're asking before they've agreed. "I'd appreciate your help with this" is a safer alternative.

"TTYL" / "xo" / "Luv" - These belong in personal texting, never in professional email. Not even with close colleagues. The risk of one of these getting forwarded to the wrong person is too high.

"Humbly" - Trying too hard to be modest can come across as insincere. Stick with straightforward closings.

Matching Your Closing to the Situation

Job Applications and Interviews

Use formal closings that project professionalism and respect:

• "Thank you for your consideration. I look forward to discussing this opportunity further."
• Closing: Sincerely, or Best regards,

After an interview, your thank-you email closing matters even more. For detailed advice, see our guide on how to write a thank-you email after an interview.

Client Communication

Match the formality to your client relationship:

• New clients: Best regards, or Sincerely,
• Established clients: Best, or Thanks,
• Always err slightly more formal than you think necessary
• When sending proposals, keep the closing professional - see our guide on writing business proposal emails for context

Internal Team Communication

Keep it efficient and warm:

• Thanks, or Best, for most situations
• Talk soon, or Have a great weekend, for casual context
• For leadership: maintain one level more formal than peer communication

Difficult or Sensitive Emails

When delivering bad news, declining requests, or addressing conflicts:

• "I appreciate your understanding on this matter."
• Closing: Best regards, or Sincerely, - never casual
• Avoid "Thanks" when you're not genuinely thanking them for anything
• For crafting difficult apology emails, see our guide on how to write an apology email

Cold Outreach

When emailing someone for the first time:

• "I'd appreciate the opportunity to discuss this further."
• Closing: Best, or Best regards,
• Avoid overly formal closings that make your email feel like junk mail
• For cold email specifically, our guide on how to write a cold outreach email covers end-to-end strategy

Follow-Up Emails

When following up on a previous message:

• "Just wanted to make sure this didn't get buried - happy to discuss whenever is convenient."
• Closing: Match the formality of your original email
• Don't escalate formality in follow-ups - it can feel passive-aggressive
• For comprehensive follow-up strategy, see how to write a follow-up email

Networking Emails

When reaching out to build professional relationships:

• "I'd love to continue this conversation - no rush on timing."
• Closing: Best, or All the best,
• Keep it warm but not presumptuous

Email Signature Best Practices

Your email signature is part of your closing and should include:

Essential elements:

• Full name
• Job title
• Company name
• Phone number (for external emails)

Optional elements:

• LinkedIn profile URL
• Company website
• Pronouns (if you want to include them)
• Professional certification abbreviations
• Calendar booking link (useful for sales and client-facing roles)

Avoid in signatures:

• Inspirational quotes (they get old fast and can seem unprofessional)
• Large images or logos that create heavy attachments
• Too many social media links
• Legal disclaimers longer than the email itself
• Multiple phone numbers and addresses (keep it clean)
• Animated GIFs or flashy graphics
• Your entire resume or bio

Keep your signature to 4-5 lines maximum. A signature that takes up more space than your email body is distracting.

Signature formatting tips:

• Use a simple divider (a line of dashes or a pipe character) to separate your signature from the email body
• Keep font sizes consistent - don't make your signature larger than your email text
• Test your signature on mobile - complex HTML signatures often break on phones
• Have separate signatures for internal and external emails (internal can be simpler)

The One Rule That Matters Most

When choosing how to end a professional email, the most important principle is consistency. Pick a closing style that fits your professional identity and use it consistently. People notice when your closing changes from email to email, and inconsistency can signal uncertainty or inauthenticity.

Find your default closing - for most professionals, "Best," or "Thanks," works perfectly - and use it for the majority of your emails. Save formal closings for situations that genuinely call for them, and casual closings for relationships that have clearly earned them.

Your email closing is the period at the end of your professional sentence. Make it count, and you'll leave every recipient with a positive final impression.

Frequently Asked Questions

What is the most professional way to end an email?

"Best regards" is the most universally professional email closing. It strikes the right balance between formal and approachable, works across cultures, and is appropriate for virtually any business context. If you only ever used "Best regards" for every professional email, you'd never go wrong.

Is "Best" too informal for professional emails?

No. "Best" has become widely accepted in professional communication and is used by executives, consultants, and professionals at every level. It's efficient, warm, and professional. The only contexts where it might be too casual are formal legal correspondence, government communications, or first-time emails to very senior executives.

Should I change my email closing depending on the recipient?

Yes, but subtly. You don't need a completely different closing for every email, but you should calibrate formality. Use "Sincerely" or "Best regards" for formal contexts, "Best" or "Thanks" for standard professional communication, and "Cheers" or "Talk soon" only for established casual relationships.

How do I end an email when I'm asking for something?

End with a specific, easy-to-accept request followed by "Thanks" or "Thank you." For example: "Could you share the report by Thursday? Thanks, Sarah." The "Thanks" implies you're grateful for their time, and the specific request makes it clear what you need.

Is it okay to end an email with just my name and no sign-off?

In very casual internal communications or rapid back-and-forth threads, dropping the sign-off is common and acceptable. But for any first email, external communication, or important internal email, always include a closing. The absence of a sign-off can feel abrupt or even rude.

How should I end an email when I'm delivering bad news?

Use a closing that acknowledges the difficulty while remaining professional. "I appreciate your understanding" or "Thank you for your patience" followed by "Best regards" or "Sincerely" works well. Avoid "Thanks" when you're not genuinely thanking them for anything - it can feel hollow.

What's the difference between "Regards" and "Best regards"?

"Regards" is slightly more neutral and can feel distant. "Best regards" adds a note of warmth and goodwill. In practice, the difference is subtle, but "Best regards" is generally preferred because it feels slightly warmer without sacrificing professionalism.

How do I end a professional email to someone I've never met?

Use "Best regards" or "Sincerely" for your first email to a stranger. These closings are safe, professional, and won't create any negative impression. As the relationship develops through subsequent emails, you can naturally shift to less formal closings like "Best" or "Thanks."
