Email Sign-Offs: Professional, Casual & Funny Closings

The way you close an email shapes how the recipient feels about the entire message. A thoughtful sign-off reinforces your professionalism, personality, and relationship with the reader. Whether you need a buttoned-up closing for a client proposal, a casual send-off for a teammate, or something funny to make someone smile, this guide has you covered with over 100 options for every situation.

Why your email closing matters

Your email closing is the last thing someone reads before deciding how to feel about your message. Research shows that emails with a professional sign-off receive higher response rates than those that end abruptly. The closing sets the emotional tone: “Best regards” says you are competent and polite, “Cheers” says you are friendly and approachable, and “Sent from my carrier pigeon” says you do not take yourself too seriously.

Your sign-off also works in tandem with your email signature. The closing is the human part (the words you choose), while the signature is the branded block below it (your name, title, contact info, and logo). Together, they create a polished, professional ending that reinforces who you are.

Professional email closings

The Vulcan salute for Star Trek fans. A safe pop culture reference.

Warmly (but not in a creepy way)

Typos courtesy of my cat

Relatable for remote workers. A charming excuse for any errors.

Respectfully, unless you disagree

A tongue-in-cheek take on professional formality.

Light sci-fi humor. Works especially well in tech and innovation spaces.

Email closings to avoid

These sign-offs can undermine your professionalism or make the recipient uncomfortable. Steer clear in business contexts.

Thx

Abbreviating "Thanks" saves you two characters and costs you credibility. It reads as lazy and disrespectful, especially in professional settings.

Sent from my iPhone

As an intentional sign-off (not the auto-generated one), this signals that you did not care enough to write a real closing. Remove the auto-generated version too if you can.

XOXO

Hugs and kisses have no place in business email. Even in casual workplaces, this crosses a professional boundary.

Love

Reserve this for personal emails to friends and family. In a work context, it creates discomfort regardless of intent.

Yours truly

This is not inherently bad, but it reads as old-fashioned and overly intimate in modern business email. "Best regards" communicates the same thing without the awkwardness.

[Nothing at all]

Ending an initial email with no closing feels abrupt and impersonal. It is fine in ongoing threads, but for first emails, always include a sign-off.

Blessings

Unless you work for a religious organization, this can feel presumptuous. The recipient may not share your beliefs.

Ciao

Using foreign-language closings when it is not your native language can come across as affected. Stick to closings that feel natural to you.

Match your closing to your email signature

Your sign-off and your email signature should feel like they belong together. A formal “Sincerely” above a playful, colorful signature creates a disconnect. Similarly, a casual “Cheers” above a stiff corporate signature with a legal disclaimer feels off.

Match the tone: if your signature is clean and minimal (name, title, phone), pair it with a professional or semi-formal closing. If your signature includes a headshot, social links, and a CTA banner, you have more room for warmth and personality in your closing.

Frequently asked questions

Common questions about email closings and sign-offs.

What is the most professional email closing?+

"Best regards" is widely considered the safest, most universally professional email closing. It strikes the right balance between formal and approachable, works in every industry, and is understood across cultures. If you need something more formal for legal, government, or first-contact emails, "Sincerely" or "Respectfully" are strong alternatives.

Is 'Best' too informal for business emails?+

"Best" on its own is perfectly acceptable for day-to-day business communication with colleagues, clients you have an existing relationship with, and internal emails. It only feels too informal in highly regulated industries (law, finance) or when writing to someone for the very first time in a formal context. When in doubt, use "Best regards" instead.

Should I use 'Thanks' or 'Thank you' as a closing?+

Use "Thank you" when the recipient has actually done something you are grateful for, or when you are making a request. It feels natural and sincere in those contexts. Avoid using it as a default closing for every email, since it can feel hollow when there is nothing to thank someone for. "Thanks" is a slightly more casual variant that works well in ongoing threads.

Is it okay to use no closing at all?+

In short, back-and-forth email threads, dropping the closing is common and generally acceptable. The conversation has already been established, and adding "Best regards" to every reply can feel stilted. However, for initial emails, formal correspondence, or messages to people you do not know well, always include a closing. It signals professionalism and intentionality.

Can I use a funny email sign-off at work?+

It depends on your workplace culture and your relationship with the recipient. In creative agencies, startups, and informal teams, a witty sign-off can reinforce your personality and make emails more memorable. In client-facing roles, legal settings, or when emailing someone for the first time, stick to a professional closing. Read the room before adding humor.

How does my email closing relate to my email signature?+

Your email closing (sign-off) is the text you type before your name, like "Best regards" or "Thanks". Your email signature is the formatted block below that with your name, title, contact info, and branding. They work together: the closing sets the tone, and the signature provides the professional details. A polished signature can make even a simple "Best" look professional.
