Every email you send says something about you. The way you close a message shapes how you’re perceived: organized, thoughtful, rushed, or disengaged. A strong email ending leaves no doubt about your professionalism, your intent, and your respect for the reader’s time.
To end an email professionally, close with a sign-off that matches your relationship with the recipient. "Best regards" and "Kind regards" are the most reliable options across business contexts. What you say in the final line before that sign-off matters just as much. A clear closing sentence that confirms your intent or invites a response tells the reader you're organized, considerate, and worth responding to.
What to say at the end of an email
The right closing depends on who you're writing to and what you need from them. A message to a new client calls for something different than a quick note to a colleague. Here's how to match your sign-off to the situation.
How to end a business email
A professional email closing is clear, courteous, and matched to the tone of your message. It signals the end of your communication and subtly reinforces your relationship with the reader. The right closing shows confidence and respect without sounding overly formal.
Here are some of the best professional email sign-offs and how to use them effectively:
Best regards: Safe and versatile. Works in almost every professional setting, from client introductions to follow-ups.
Fyxer organizes your inbox and drafts replies in your voice.
Kind regards: Slightly warmer than “Best regards.” Use it when you want to sound approachable but still professional.
Sincerely: Best for formal correspondence, job applications, or outreach to senior leaders.
Warm regards: Adds a human touch to professional exchanges, especially with long-term clients or partners.
Yours faithfully: Common in formal letters or traditional corporate settings, especially when you don’t know the recipient by name.
Yours truly: Still formal, but softer.
Each closing line should feel intentional. If your message is formal, stick to traditional options. For ongoing client relationships or internal communication, a slightly friendlier tone is fine.
According to the Fyxer Admin Burden Index, 2026, a survey of 5,000 UK and US office workers, the average professional receives 29 emails per day that require a response. At that volume, the way you close each one starts to matter less as courtesy and more as professional currency.
Not every email needs a strict, formal ending. When writing to colleagues, partners, or customers you know well, a warmer tone helps you sound human and genuine.
Examples of polite and friendly closings include:
Thanks again: Ideal after someone has helped you or provided information.
Thanks in advance: Best if you’ve asked for something to be done by the recipient.
Talk soon: Great for casual business relationships or ongoing collaborations.
Cheers: Friendly and relaxed, often used in internal or team communication.
Have a great day: Universal and positive. Works well in lighter exchanges or customer service messages.
And if you ever doubt the power of gratitude, data backs it up. A 2017 Boomerang study that analyzed over 350,000 emails found that messages ending with “Thanks in advance” received the highest response rate at 65.7%, followed by “Thanks” at 63%, and “Thank you” at 57.9%. Gratitude-based closings consistently encourage replies because they acknowledge effort and set a positive tone; something every professional exchange can benefit from.
The key is to stay professional while matching the relationship you have with the recipient. A casual “Cheers” may work for your design team but not for a potential investor. When in doubt, lean slightly formal. It’s easier to relax your tone later than to repair a first impression.
How to end a formal email
Formal emails call for a little more care than everyday correspondence. Whether you're writing to someone you've never met, reaching out to a senior stakeholder, or sending a message that could be forwarded or filed, your closing needs to hold up under scrutiny. Keep it brief, respectful, and free of anything that could read as too casual.
Here are the best sign-offs for formal emails and when to use each one:
Sincerely: The go-to for formal correspondence. Works well for job applications, official requests, and first-time outreach to senior contacts.
Yours faithfully: Use this when you don't know the recipient's name and have opened with "Dear Sir/Madam." Common in legal, government, or traditional corporate contexts.
Yours truly: Slightly softer than "Yours faithfully," but still formal. More common in North American business writing.
Respectfully: Reserved for very high-stakes or hierarchical correspondence, like messages to public officials, or academic institutions.
With appreciation: A formal way to close when you're thanking someone for their time or assistance, without sounding overly effusive.
The closing line that comes before your sign-off matters just as much. In a formal email, something like "Thank you for your time and consideration" or "I look forward to hearing from you" keeps the tone consistent and gives the reader a clear sense of what you're expecting next. Avoid anything that sounds rushed or assumes too much familiarity.
Email closing examples by context
Different situations call for different endings. Here are examples of how to close emails effectively across common professional scenarios.
1. Job application or cover letter
Keep your tone polite, confident, and formal. Express gratitude and interest without overdoing it.
Example:
Thank you for considering my application. I’d welcome the opportunity to discuss how my skills could contribute to your team.
Sincerely, Jordan Ellis
2. Client communication
When writing to clients, professionalism is key. You want to sound organized and attentive, without being overly stiff.
Example:
Please find the updated proposal attached. Let me know if there’s anything you’d like adjusted before we finalize it.
Best regards, Taylor Morgan
3. Follow-ups
Follow-up emails should be courteous and concise. Acknowledge the delay or previous contact, and end with a gentle nudge toward action.
Example:
Just following up on my previous email to see if Wednesday still works for a quick call. Looking forward to hearing from you.
Kind regards, Alex Rivera
4. Networking or introductions
Networking emails should feel warm and personal. A friendly closing encourages future contact.
Example:
It was great connecting with you after the panel discussion. I’d love to stay in touch and hear more about your work with the startup community.
Warm regards, Jamie Chen
5. Customer support or service
When ending customer service emails, gratitude and clarity go a long way. Keep it brief, helpful, and reassuring.
Example:
Your account settings have been updated as requested. Please let us know if there’s anything else we can do to help.
Have a great day, Customer Support Team
6. How to end an email that requires a response
When you need a reply, your closing should make that clear without sounding demanding. A vague sign-off like "Let me know" leaves too much open. Be specific about what you're asking for and, where possible, give the reader a timeframe to work with.
Example:
I'd appreciate your thoughts on the proposal before our call on Thursday. Please let me know if you have any questions in the meantime.
Kind regards, Sam Okafor
7. How to end an email with thank you
Gratitude-based closings are some of the most effective in professional email. They leave a positive impression and, according to a Boomerang analysis of over 350,000 emails, consistently generate higher response rates than neutral sign-offs. The key is making the thanks feel specific rather than reflexive.
Example:
Thanks so much for taking the time to walk me through this, it's really helpful to have that context before the meeting.
Many thanks, Jordan Park
What to avoid when ending an email
The right sign-off builds trust. The wrong one can leave a poor impression or confuse the tone. Here are common mistakes to avoid:
Skipping the closing entirely: Ending abruptly makes your email feel unfinished or impatient.
Using slang or emojis in professional settings: A casual “Thx” or smiley face might seem friendly but can read as unprofessional in business contexts.
Being inconsistent with tone: If your email is formal, don’t end it with “Cheers.” Match your sign-off to the rest of your message.
Leaving in “Sent from my iPhone”: It’s fine to send emails from your phone, but customize your mobile signature with your name and title.
Ending without a clear next step: A polite closing line is best paired with a call to action. Example: “Looking forward to your thoughts” or “Please confirm by Friday.”
Weak closing:
Let me know. Sent from my iPhone
Stronger closing:
Please let me know by Friday if this works for your team.
Kind regards, Dana Patel
How to add an email signature in Gmail and Outlook
A professional signature shows credibility and helps recipients find your contact information easily. It also adds a consistent finish to every message you send.
The way you close an email is the last thing a reader sees before they decide what to do next. A clear, considered sign-off signals that you're organized and in control. A rushed or mismatched one undermines everything that came before it.
The choices here aren’t complicated. Pick a sign-off that fits the tone of your message. Write a closing line that makes the next step obvious. Do it consistently, and it becomes one less thing to think about every time you hit send.
Professional email ending FAQs
Is “Thanks” too casual for business emails?
Not necessarily. “Thanks” is fine when you’re acknowledging someone’s help or cooperation. Just avoid overusing it in every message, or it can lose impact. If you’re expressing genuine appreciation, a simple “Thanks again” or “Many thanks” adds warmth without sacrificing professionalism.
Should I use my full name in every signature?
Yes. Always include your full professional name and job title in emails. It looks credible and helps recipients identify you easily. You don’t need to use your full legal or “government” name, just the version you’re known by in your work.
If you use your middle name or initial professionally, include it. If you go by a shorter name like Maddy instead of Madeleine, use that for consistency. For client-facing roles or formal communication, adding your company name and contact details reinforces trust and makes follow-ups effortless.
How do I sign off emails to clients?
It's generally ideal to use sign-offs like “Best regards,” “Kind regards,” or “Warm regards.” These sound polished and friendly without being too familiar. If you’ve built a long-term relationship, a slightly more personal touch such as “Thanks again” or “Appreciate your time” can help maintain rapport while staying professional.
