Professional Email Sign-Offs: 25+ Closings That Drive Replies

The last two words of your email do more work than you think. A weak closing softens a strong pitch. A mismatched closing makes a polished message feel off. And in cold outbound, where reply rate is the only number that matters, the sign-off is one of the cheapest levers you have to test.

This guide is for SDRs, account executives, founders running outbound, and anyone who writes a lot of professional email. You will find 25+ closings sorted by use case, the rules that govern when each one fits, what to avoid, how to A/B test sign-offs in a real sequence, and 10 ready-to-paste Zeliq-style examples you can plug into your next campaign.

Why your email closing actually matters

A sign-off does three jobs at once. It signals tone, so the reader knows whether to treat you as a peer, a vendor, or a stranger. It frames the next step, telling the prospect whether you expect a reply, a meeting, or nothing. And it lands the human moment, the small piece of warmth that makes a B2B email feel less like a templated drip.

In cold email specifically, the closing is read more carefully than the body. Most prospects skim. They scan the first line, check the ask, and look at the signature. A closing that matches the rest of the message keeps them in. A closing that feels generic, robotic, or off-tone gives them an excuse to archive.

There is also a deliverability angle. Long, link-heavy signature blocks with banners and tracking pixels tank inbox placement. A clean sign-off plus a stripped down signature beats a designer-built footer almost every time on cold outbound.

Anatomy of a professional email closing

Every professional closing has two parts that you should think about separately.

The sign-off line. One short phrase, one or two words usually, ending with a comma. This is where tone lives. “Best regards,” sets a different temperature than “Cheers,” or “Onwards,”.

The signature block. Your name, role, company, and at most one or two ways to reach you. Optional: a one-line value prop, a calendar link, a relevant social URL.

The two need to agree. A casual “Cheers,” followed by a corporate signature block with three logos and a legal disclaimer reads as confused. A formal “Sincerely yours,” followed by a one-line signature with just a first name reads as careless. Pick a register and commit to it across both.

25+ professional email closings, sorted by use case

The right closing depends on who you are writing to and what you want next. Here are 25+ options grouped by register, with notes on when each fits.

Formal closings (regulatory, legal, executive cold outreach)

Use these for senior executives at conservative companies, legal or compliance contexts, or first-touch emails to industries where formality is expected (banking, government, law, parts of healthcare).

• Sincerely,
• Sincerely yours,
• Yours truly,
• Yours faithfully, (UK, when you do not know the recipient’s name)
• Respectfully,

These read as deliberate and old-school. In modern SaaS sales they can feel stiff, but in the right context they signal that you understand the room.

Neutral professional closings (the safe defaults)

If you are unsure, pick from this set. They work across industries, seniorities, and geographies.

• Best regards,
• Kind regards,
• Regards,
• Best,
• Warm regards,

“Best regards,” is the workhorse of B2B email. Hard to get wrong, never stands out, never offends. “Kind regards,” skews slightly more British. “Regards,” on its own can feel cold in cold outbound, save it for follow-ups where you have already established a thread.

Warm closings (relationship building, networking)

When you want the email to feel human and you have some context with the recipient.

• Best wishes,
• All the best,
• Warm wishes,
• Take care,
• With appreciation,

These work well for founder-to-founder cold email, post-event follow-ups, and any thread where the relationship is the point. Avoid for first-touch enterprise outbound, they can read as too familiar.

Sales action closings (cold email and follow-ups)

These do real work. They prompt a specific next step or reduce the cost of a reply.

• Looking forward to your thoughts,
• Looking forward to hearing from you,
• Open to feedback,
• Thanks in advance,
• Talk soon,
• Speak soon,
• Worth a quick chat?
• Happy to share more,

“Looking forward to your thoughts,” is the SDR favorite for a reason. It assumes engagement without being pushy. “Worth a quick chat?” works as a closing line right before the sign-off, doubling as a soft CTA. “Thanks in advance,” can feel presumptuous if your ask is heavy, use it only when the ask is small (a 15-minute call, a forwarded contact).

Casual closings (existing relationships, fast threads)

Once you are deep in a thread or you know the person, these keep the rhythm light.

• Cheers,
• Thanks,
• Thanks!,
• Talk later,

“Cheers,” is widely accepted in UK and Australian business culture, more casual in the US. “Thanks,” works almost everywhere as long as you actually have something to thank for. Drop it on a cold first-touch email and it reads as filler.

Creative closings (memorable, off-pattern)

Use sparingly. The point is to be remembered, not to be quirky for its own sake.

• Onwards,
• To the next one,
• Stay sharp,
• Until next time,

These work in a sequence where you want one specific email to break pattern, the breakup email being the classic example. They do not work as defaults, the second time a prospect sees “Onwards,” from you it loses its edge.

What to avoid in a professional email closing

A few closings consistently underperform or actively hurt your credibility.

“Sent from my iPhone.” Reads as careless on a planned outbound message. Acceptable on a quick reply from your phone, never on a templated email.

“Thx” or “Tx.” Too informal even for a thread that is going well. The two saved seconds are not worth the cost.

“Cheers,” in a formal first-touch. Fine in casual UK or AU contexts, awkward in a cold email to a senior US executive.

“Hope this helps!” as a closing on outbound. You have not helped yet, you have asked for time. Reserve it for replies where you actually answered something.

“-Name” alone with no sign-off line. Curt to the point of rudeness on a cold message. Save it for replies inside an active thread.

Long inspirational quotes in the signature. A Gandhi quote under your job title is not the personality differentiator you think it is. Strip it.

Choose your closing by context

Different sequence stages and use cases call for different closings. Here is a quick mapping you can steal.

Cold first-touch outbound. Default to “Best regards,” or “Looking forward to your thoughts,”. They set a professional tone without overpromising. If your persona skews founder or technical, “Best,” works too.

Follow-up email (no reply yet). Switch register slightly to keep the thread fresh. If you opened with “Best regards,” try “Looking forward to your thoughts,” on touch 2. Variation matters more than the specific words.

Post-demo follow-up. Warm and forward-looking. “Talk soon,” or “Looking forward to next steps,” fits. The relationship has started, lean into it.

Breakup email. This is where creative closings earn their keep. “Onwards,” or “Wishing you the best,” signal that you are genuinely closing the loop, not just trying another guilt trip.

Networking and peer outreach. “All the best,” “Take care,” or “Best wishes,” fit the human register. You are not selling, you are connecting.

Recruiter outreach (you are the candidate). “Best regards,” is the safe pick. “Looking forward to your thoughts,” works if the recruiter has shared a role and you want to signal real interest.

Recruiter outreach (you are reaching out as a recruiter). Match the seniority of the candidate. Senior engineers respond better to “Best,” than to “Warm regards,”.

Internal email to your team. Skip the sign-off entirely or use “Thanks,”. Pretending you are formal with people you saw in standup looks weird.

Region and culture matter

Sign-offs translate poorly across business cultures. A few rules of thumb.

United States. Pragmatic, slightly informal at the edges. “Best,” “Best regards,” and “Thanks,” are the dominant trio. “Cheers,” reads as British-affected unless you actually are.

United Kingdom. “Kind regards,” is the equivalent of “Best regards,” in the US. “Yours faithfully,” still appears in formal letters when the recipient name is unknown, “Yours sincerely,” when it is known. “Cheers,” is acceptable in casual business email.

Australia. Friendlier register overall. “Cheers,” is fully professional. “All the best,” is common.

Germany, Switzerland, Austria. When writing in English to German-speaking executives, lean formal. “Best regards,” or “Kind regards,”. They will appreciate the deliberate tone.

Japan, Korea, much of East Asia. Formality matters. Default to “Best regards,” or “Sincerely,”. Avoid “Cheers,” and “Thanks!” on first touch.

France, Belgium, Switzerland (French-speaking). When you switch from French to English with the same contact, do not translate the long French closing literally. “Best regards,” is the right English equivalent of “Cordialement,”.

When in doubt across cultures, “Best regards,” travels better than any other choice.

Signature block essentials

The closing line sets tone. The signature block delivers credibility. Keep it tight.

Must have. Full name, role, company.

Nice to have. One direct way to reach you (calendar link or phone), one social link if it adds context (LinkedIn for sales, GitHub for technical roles).

Skip. Banners, animated GIFs, multiple logos, legal disclaimers in cold outbound, motivational quotes, your favorite emoji, your pronouns in 14 languages.

A clean signature looks like:

Maya Chen Account Executive, Acme Co. calendly.com/maya-acme

Three lines. Easy to scan, easy to act on, easy on deliverability.

If you want to test cold sequences with this kind of clean structure across email and LinkedIn at scale, Zeliq’s multichannel sequences let you build the sequence once and run it on email, LinkedIn, and calls in one workflow, so the only thing you tweak between touches is the message itself.

Common mistakes to fix this week

A few patterns that quietly kill reply rates.

Mismatched register. A “Hey Maya!” opener with a “Sincerely yours,” closer reads as software-glued. Pick a temperature and hold it across the email.

Closing that contradicts the ask. “Looking forward to your thoughts,” after a hard pitch with no question reads as confused. If your email did not invite thoughts, do not pretend it did.

Too many closings. “Thanks again, looking forward to your thoughts, talk soon, best regards,” is four closings stacked. Pick one.

Forgetting the comma. “Best regards” without the comma is a small thing that looks unfinished. Add it.

Auto-inserted “Sent from Outlook for iOS” on planned messages. Strip it from your mobile signature when you write outbound from your phone.

A different signature on every reply in the thread. If your formal first-touch signature has six lines and your reply has zero, the prospect notices. Use a consistent reply signature.

A/B testing your closings inside a sequence

Reply rate moves on small things. Sign-offs are one of the cheapest variables to test, because the rest of the email stays identical. Here is the cleanest way to run it.

Pick two closings with real distance between them. Testing “Best regards,” against “Kind regards,” tells you nothing useful. Test “Best regards,” against “Looking forward to your thoughts,” or “Best,” against “Worth a quick chat?”.

Run them on the same touch, same body text, same subject line. Split your prospect list 50/50 by deterministic hash, not first half versus second half. Order effects on prospect lists are real.

Wait for statistical significance. On cold outbound you usually need 200+ sends per variant for the result to mean anything. Below that, noise dominates signal.

Test on the touch that actually moves. If touch 1 closings show no difference but touch 3 closings do, the lever is the follow-up tone, not the opener.

Promote the winner, retire the loser, design the next test. Sign-off testing compounds. Every locked-in winner frees you to test the next variable.

Frequently asked questions

What is the most professional email sign-off?

“Best regards,” is the safest professional sign-off across industries, geographies, and seniorities. It reads as deliberate without being stiff, and it never feels out of place in a B2B context.

Is “Best” too casual for business email?

“Best,” is acceptable in modern B2B email, especially in the US tech and SaaS world. It can read as too clipped in conservative industries (banking, law, government), where “Best regards,” lands better.

Should I use the same closing in every email?

No. Vary your closing across touches in a sequence so the messages do not feel templated. Inside a thread that is already going well, you can drop the closing entirely on short replies.

What is a good cold email sign-off for sales?

“Looking forward to your thoughts,” is the strongest default for cold outbound. It assumes engagement without being pushy. “Worth a quick chat?” placed just before “Best regards,” works as a soft CTA and closing combination.

Is “Cheers” professional?

“Cheers,” is fully professional in UK and Australian business culture and acceptable in casual US business email. Avoid it on formal first-touch outbound to senior executives or in conservative industries.

What should I avoid in an email signature?

Skip motivational quotes, animated banners, multiple logos, large images, and legal disclaimers on cold outbound. Keep your signature block to three or four lines maximum.

Ship better closings, ship better sequences

The right sign-off is a small lever. Compounded across thousands of cold emails, follow-ups, and post-demo notes, it moves real numbers. Pick a default that fits your register, vary it intentionally across touches, test the closings that matter on the touches that matter, and keep your signature block clean.
