How to end an email: professional sign-offs and closing lines

Why the Way You End an Email Matters

The last line of your email is the last thing your reader sees. It shapes their impression of the entire message and determines whether they take the action you want.

A weak ending leaves the reader unsure of what to do next. A strong ending provides clarity, reinforces the purpose of the email, and makes it easy to respond.

Email endings also set the tone for the relationship. Signing off with "Best" to a close colleague feels distant. Signing off with "Cheers" to a C-level executive you have never met feels presumptuous. Matching the closing to the context is a small detail that signals professionalism and awareness. Understanding email etiquette helps you make these judgment calls consistently.

The Two Parts of an Email Ending

Every email ending has two components that work together.

The closing line

This is the final sentence of the email body. It tells the reader what you want them to do, summarizes the key takeaway, or expresses a relevant sentiment.

- "Let me know if Tuesday at 2pm works for your schedule."

- "I have attached the proposal for your review."

- "Happy to jump on a call if any questions come up."

The closing line is where most of the work happens. It carries the call to action and sets expectations.

The sign-off

This is the word or phrase that appears before your name. It is a social signal, not a content carrier.

- "Best regards,"

- "Thanks,"

- "Looking forward to it,"

The sign-off should match the tone of the email and the relationship with the recipient. It should not try to do the job of the closing line.

How to Write a Strong Closing Line

Start with the purpose of the email

Your closing line should connect directly to why you sent the email in the first place.

- If you are requesting something: state the specific request and deadline.

- If you are providing information: highlight the key takeaway.

- If you are following up: restate what you need from the recipient.

- If you are building a relationship: express genuine interest or offer value.

Make the next step obvious

The reader should never have to guess what you want them to do after reading your email. Be specific.

- Weak: "Let me know your thoughts."

- Strong: "Could you confirm the budget figure by Thursday so I can finalize the deck?"

- Weak: "Looking forward to hearing from you."

- Strong: "Would either Monday at 10am or Wednesday at 3pm work for a 30-minute call?"

Keep it to one sentence

Closing lines that run two or three sentences lose their punch. If you need to cover multiple points, handle them in the body of the email and keep the closing focused on a single action or sentiment.

Professional Sign-Offs by Context

Formal business emails

Use these when writing to clients, senior executives, external partners, or anyone you do not have an established relationship with.

- Best regards,

- Kind regards,

- Regards,

- Respectfully,

- Sincerely,

"Best regards" is the safest default for professional communication. It is warm enough to avoid feeling cold, but formal enough for any business context. For more on structuring formal messages from start to finish, see our guide on how to write a formal email.

Everyday workplace emails

Use these for colleagues, cross-functional teammates, and people you email regularly.

- Best,

- Thanks,

- Thank you,

- Talk soon,

- Appreciate it,

"Best" and "Thanks" are the workhorses of internal email communication. They are neutral, efficient, and universally accepted.

Warm or relationship-driven emails

Use these when you have an established relationship with the recipient and want to convey warmth.

- Cheers,

- All the best,

- Warmly,

- Looking forward to it,

- Take care,

These work well for mentors, long-term clients, and colleagues you have a friendly rapport with. Avoid them with people you are emailing for the first time.

Sales and outreach emails

Use these when sending cold outreach, follow-ups, or partnership inquiries.

- Looking forward to connecting,

- Happy to chat whenever works,

- Talk soon,

- To your success,

Sales sign-offs should project confidence without being pushy. The goal is to signal openness to a conversation, not to close a deal in the email itself. If your outreach emails are not getting replies, learning how to follow up on a cold email can improve your response rates significantly.

Thank-you and appreciation emails

Use these when the primary purpose of the email is to express gratitude.

- With thanks,

- Gratefully,

- Much appreciated,

- Thanks again,

If the entire email is a thank-you, double-thanking in the sign-off can feel redundant. Use a closing line that adds specificity ("Your feedback on the Q3 report was exactly what we needed") and keep the sign-off simple. For dedicated gratitude messages, our collection of thank-you email examples provides templates for every situation.

Sign-Offs to Avoid

"Sent from my iPhone"

This is not a sign-off. It is a default signature that tells the reader you did not care enough to personalize it. Remove it or replace it with a real sign-off.

"Thx" or "Ty"

Abbreviations in sign-offs signal carelessness. If you are going to thank someone, spell it out.

Oversized signature blocks

Signature blocks that are longer than the email body are distracting. Keep your signature concise: name, title, company, and one contact method.

"Warm regards" to strangers

"Warm regards" implies an existing relationship. Using it with someone you have never met can feel presumptuous or insincere.

No sign-off at all

Ending an email with just your name (or nothing at all) can come across as abrupt, especially in initial communications. Always include a sign-off unless you are deep in a rapid back-and-forth thread where formalities have naturally dropped.

How to End Specific Types of Emails

Ending a request email

Close with the specific request and a deadline. Make it easy for the reader to say yes.

"Could you send me the updated numbers by end of day Friday? I need them for the board deck."

Sign-off: "Thanks," or "Much appreciated,"

Ending a cold outreach email

Close with a low-friction call to action. Do not ask for a 30-minute call in the first email. Ask for interest.

"Would it be worth a quick conversation about this? Happy to work around your schedule."

Sign-off: "Best," or "Looking forward to connecting,"

Getting the length of your outreach right matters as much as the closing. Our guide on how long a cold email should be covers the data behind optimal email length.

Ending a follow-up email

Close by restating the original ask and making it easy to respond. Add a reason for urgency if genuine.

"Just circling back on the proposal I sent last Tuesday. We are finalizing vendor selections this week, so any feedback would be helpful."

Sign-off: "Thanks," or "Appreciate your time,"

Ending a thank-you email

Close with a specific detail about what you are thanking them for. Generic gratitude is forgettable. Specific gratitude is memorable.

"The introduction to Sarah was incredibly helpful. We have already scheduled a call for next week."

Sign-off: "With thanks," or "Gratefully,"

Ending an email to your manager

Close with a clear status update or question. Managers receive dozens of emails daily and need to quickly understand what action is required.

"I will proceed with option B unless you have concerns. Let me know by tomorrow if you would prefer a different approach."

Sign-off: "Best," or "Thanks,"

Ending a networking email

Close with an offer of value or a specific ask. Vague requests ("Would love to connect sometime") are easy to ignore.

"I would love to hear how your team handled the migration to Salesforce. Would you be open to a 15-minute call next week?"

Sign-off: "All the best," or "Looking forward to it,"

Common Mistakes When Ending Emails

Apologizing unnecessarily

Phrases like "Sorry for the long email" or "Sorry to bother you" undermine your message. If the email needed to be long, it needed to be long. Do not apologize for communicating.

Being vague about next steps

"Let me know" without specifying what you need to know, by when, and in what format gives the reader an excuse to do nothing. Always close with specifics.

Mismatching tone

A formal email body with a casual sign-off (or vice versa) creates a jarring experience. If the body of your email uses "Dear" and full sentences, do not sign off with "Cheers." Consistency builds trust.

Including a call to action in the sign-off

The sign-off is not the place for your ask. "Thanks in advance for sending the report" forces your gratitude and your request into one awkward phrase. Put the request in the closing line and keep the sign-off clean.

Overusing "Please let me know if you have any questions"

This closing line is so overused that it has become invisible. Readers skim right past it. If you genuinely want questions, be specific: "If anything in the budget section is unclear, I am happy to walk through it." For fresher alternatives to overused phrases, check out our list of alternatives to "I hope this email finds you well" and alternatives to "looking forward to hearing from you".

FAQ

What is the most professional way to end an email?

"Best regards" followed by your name is the safest and most universally appropriate professional email ending. It works across industries, cultures, and levels of seniority.

Is "Best" too casual for business emails?

No. "Best" is widely accepted in professional communication. It is appropriate for most workplace emails, including those to clients and senior leaders. The exception is highly formal contexts like legal correspondence or diplomatic communication, where "Sincerely" or "Respectfully" may be more appropriate.

Should I use a different sign-off for every email?

No. Consistency is more important than variety. Pick two or three sign-offs that fit your communication style and use them regularly. Rotating through a dozen different closings does not make you more interesting. It makes your emails feel inconsistent.

How do I end an email when I am upset or frustrated?

Keep it professional. Do not let frustration leak into your sign-off. Write the email, review it, and ensure the closing is neutral and action-oriented. "Please confirm the corrected figures by Friday" is more effective than any passive-aggressive closing.

Do I need a sign-off in every email?

In an initial email or any standalone communication, yes. In a rapid back-and-forth thread where both parties have dropped formalities, it is acceptable to send a reply without a formal sign-off. Use your judgment based on the context and relationship.
