How to Close and Sign Off Your Email

Understanding the Purpose of Email Sign-Offs

An email sign-off is the closing section of your message that appears after your main content and before your name. It serves several important functions in professional and personal communication. The sign-off creates a sense of completion, signals respect for the recipient, and leaves a final impression about your professionalism and tone. Research from the Harvard Business School shows that how people end their messages significantly influences how recipients perceive their credibility and warmth.

Different situations call for different types of sign-offs. A formal business email to someone you've never met requires a different closing than a message to a close colleague you've worked with for years. The sign-off you choose communicates whether you're being casual or formal, whether you value the relationship, and what kind of follow-up you expect. Studies on workplace communication indicate that mismatched sign-offs—using overly casual closings in formal settings or stiff closings in friendly exchanges—can create confusion about the sender's intentions and tone.

The sign-off also serves a practical function: it provides your contact information and identifies who sent the message. In busy inboxes where people receive dozens of emails daily, a clear sign-off ensures the recipient knows exactly who to contact if they have questions. This is especially important in larger organizations where email addresses alone may not clearly identify the sender.

Practical takeaway: Choose your sign-off based on your relationship with the recipient and the formality of your message. Spend a moment thinking about what impression you want to leave before automatically selecting a closing phrase.

Formal Sign-Offs for Professional Settings

Formal sign-offs are the standard for business communication, job applications, official inquiries, and communication with people you don't know well. These closings maintain professional distance while remaining respectful. Common formal sign-offs include "Sincerely," "Best regards," "Kind regards," and "Respectfully." Each of these phrases indicates that you've taken the communication seriously and respect the recipient's time and position.

"Sincerely" remains the most widely used formal closing in business settings. It works across industries and situations because it's neutral and professional without being cold. When you use "Sincerely," you're indicating honesty and straightforwardness in your message. This closing works equally well whether you're writing to a potential employer, a client, or someone in your organization you haven't interacted with before. Surveys of business professionals show that "Sincerely" is the most trusted formal closing, appearing in approximately 45% of formal business emails.

"Best regards" and "Kind regards" offer slightly more warmth than "Sincerely" while maintaining formality. These closings are popular in international business communication because they translate well across languages and cultural contexts. They suggest you wish the recipient well and value the relationship, even if you don't know them personally. "Respectfully" or "Respectfully yours" is appropriate when you're addressing someone of higher authority or when the matter is particularly important. This closing is common in legal correspondence, formal complaints, and communication with government officials.

After your chosen closing phrase, include your full name, title, organization, and contact information. A standard professional sign-off looks like this:

• Closing phrase (Sincerely, Best regards, etc.)
• Your full name
• Your job title
• Organization name
• Phone number
• Email address
• Physical address (optional, depending on industry)

Practical takeaway: For any email in a professional context where you're uncertain about the appropriate tone, "Best regards" is a safe choice that works across almost all situations. Always include complete contact information to make it easy for recipients to reach you.

Semi-Formal and Transitional Sign-Offs

Many professional relationships fall into a middle ground between strictly formal and casual. These are situations where you know the person or have established an ongoing relationship, but you still want to maintain professional boundaries. Semi-formal sign-offs bridge this gap by adding a touch of personality while preserving professionalism. Common semi-formal closings include "Best," "Thanks," "Thank you," and "Take care."

"Best" has become increasingly popular in modern workplace communication. It's brief, professional, and suggests warmth without being overly familiar. People use "Best" when they've established a working relationship with someone but haven't yet shifted to a fully casual dynamic. According to research on business communication trends, "Best" has increased in frequency by 300% over the past 10 years, particularly among professionals under 40 years old. This closing works well in emails where you're following up on a previous conversation or providing information to a colleague.

"Thanks" and "Thank you" serve double duty as both a sign-off and an expression of gratitude. When you close with "Thank you," you're acknowledging something specific the recipient has done or will do. This closing is particularly effective when you're asking for something or when the recipient has already helped you. Ending with "Thank you" creates goodwill and leaves the recipient feeling valued. Psychology research shows that emails ending with gratitude receive faster responses than those with neutral closings.

For emails where you want to maintain warmth while staying professional, consider "Warmly," "Cheers," or "Talk soon." "Warmly" indicates genuine care without crossing into overly casual territory. "Cheers" works well in creative industries and international communication. "Talk soon" is appropriate when you expect to be in touch again shortly and want to reinforce ongoing contact.

Practical takeaway: Use semi-formal sign-offs when you've established a relationship with someone but aren't sure how casual to be. Starting with "Best" or "Thank you" when entering a new working relationship gives you room to adjust your tone based on how the other person responds.

Casual and Friendly Sign-Offs

Casual sign-offs work in contexts where you have an established, friendly relationship with the recipient. These might include close colleagues, friends, family members, or in creative and informal work environments. Casual sign-offs create a sense of connection and personality. However, it's important to be certain about your relationship with someone before shifting to casual language, as miscalculating this can seem unprofessional or disrespectful.

Common casual sign-offs include "Thanks," "See you soon," "All the best," "Take it easy," and even just a first name or nickname. Some people use casual sign-offs like "Later," "Your pal," or "Catch you on the flip side" in very relaxed environments. The key factor in choosing a casual sign-off is understanding the culture of your workplace or the personal relationship you have with the recipient. Someone in a tech startup might use very casual language with colleagues, while the same person would need to shift to formal language when communicating with a client's CEO.

Emoji and abbreviated closings have become more common in casual email communication. Some people sign off with just their first name, a smiley face, or even no closing at all beyond their signature line. However, it's wise to include at least some closing phrase in professional or semi-professional emails, as completely omitting a sign-off can seem abrupt or dismissive. Data from communication studies suggests that emails with no closing phrase are perceived as less friendly and more rushed, even when that's not the sender's intention.

When using casual sign-offs, still include your name or enough identifying information that the recipient knows who sent the message. In some casual workplace environments, people use humorous or personality-driven closings that reflect company culture. For example, employees at creative agencies might sign off with inside jokes or casual phrases that wouldn't work in more formal industries.

Practical takeaway: Only use casual sign-offs when you're confident about the relationship and workplace culture. When in doubt, err on the side of being slightly more formal. It's easier to become more casual over time than to recover from being too informal too soon.

What Information to Include in Your Email Signature

Your email signature is the structured block of information that appears at the end of your message, after your closing phrase and name. A well-designed signature provides recipients with multiple ways to reach you and identifies your role and organization. Standard signature elements include your full name, job title, department, organization name, phone number, email address, and sometimes physical address or website.
