How to End an Email: 9 Sign-Offs That Get Replies
You’ve probably written a careful message, signed off on autopilot, and waited.
Unfortunately, most emails lose the reply in those last lines, and in sales that silence is a meeting that never happens. Most advice only covers the sign-off, so our Ask → Thank → Name Close handles all three parts, and flags one popular sign-off that backfires in cold outreach.
This guide covers:
- Nine sign-offs, with when to use and avoid each
- Closing-line templates for favors, deadlines, and tense threads
- Cold email endings that earn an answer
P.S. This advice comes from the live campaigns behind our #1 Agency on SmartLead 2025 ranking. Book a call to hand the whole program to us.
TL;DR
- Three decisions: closing line, sign-off, signature. Fix the one that’s costing you replies.
- Use our Ask → Thank → Name Close: one answerable ask, a gratitude-based sign-off where it fits, and a lean signature.
- Default to “Thanks” or “Best regards”; match the other person’s formality.
- Skip “Thanks in advance” on cold first touches. It presumes a yes.
- For outbound, keep signatures plain text and send from a warmed, dedicated domain.
The 3 parts of a professional email ending
A professional email ending comes down to three separate decisions. Most guides cover only the sign-off, the smallest of the three. Split them, and you can see which one is costing you replies.
We use one model for all three: the Ask → Thank → Name Close.
- Ask: one closing line with a single, answerable next step.
- Thank: a gratitude-based sign-off where the relationship supports it.
- Name: a lean signature, plain text for outbound.
The closing line: one ask, stated plainly
The closing line is the only part of your ending that tells the reader what to do. Make it easy to answer in one reply, or it gets pushed to “later,” which usually means never.
- Make one request per email. Several asks split attention and invite no answer.
- Make it answerable in one line: a yes/no question, a choice between two times, or a specific date.
- Cut the filler. Weak: “Let me know your thoughts.” Strong: “Can you confirm by Friday whether the Q3 budget is approved?”
The sign-off: match the relationship, not habit
The sign-off sets the final tone, so it should reflect where the relationship stands today.
- Mirror the other person’s formality. If they sign “Best,” don’t answer with “Yours faithfully.”
- Warm it up as the thread does. Use “Best regards” for first contact, then “Best” or “Thanks” once you’re mid-conversation.
The signature: short beats impressive
Your signature answers “Who is this, and how do I reach them?” Anything beyond that competes with your closing line for attention.
- Include the essentials: full name, title, company, and one phone number or link.
- Use a lighter signature inside threads. Keep the full block for first emails and trim it to name and title on replies.
- Never let “Sent from my iPhone” be your only ending. It reads as an afterthought.
9 email sign-offs that get replies
Each entry below shows when to use the sign-off, when to avoid it, and a closing line to pair with it.
1. Thanks
Thanks is the best all-purpose business sign-off. It fits peers, clients, and vendors, and it works whenever your closing line asks for something.
- Best for: requests, scheduling, and active threads.
- Avoid when: you’re not asking or thanking anyone for anything, since it can ring hollow.
- Example: “Can you confirm the revised scope by Friday? Thanks, Jane”
2. Thanks in advance
Thanks in advance is a gratitude closer, and thread-level data tends to favor it. It also assumes the reader will say yes. That works when you have an existing relationship and a small, reasonable ask.
- Best for: teammates and clients who already know you.
- Avoid when: you’re writing a first-touch cold email or emailing a senior stranger. This is our contrarian point: the best-performing sign-off in general threads is the wrong one for cold outreach.
- Example: “Could you send the final deck by noon? Thanks in advance, Sam”
3. Thank you
Thank you is more deliberate than “Thanks.” It acknowledges that the reader is doing something for you, which makes it a strong fit when you ask for a favor.
- Best for: after someone helps you, or when asking a favor.
- Avoid when: the thread is fast and casual. It can feel heavy.
- Example: “Would you be open to a 10-minute review by Thursday? Thank you, Priya”
4. Appreciate it / Appreciate your help
Appreciate your help works when the reader is giving up time. Specific gratitude beats generic thanks because it shows you know what you’re asking for.
- Best for: favors and help requests.
- Avoid when: you’re writing to someone very senior or formal, where “Thank you” is safer.
- Example: “Appreciate you looking at this before Friday. Appreciate your help, Dana”
5. Best regards
Best regards is the safe default for first contact with a client, partner, or executive. It’s polite and neutral, and it won’t offend anyone.
- Best for: first emails to clients, partners, and execs.
- Avoid when: the thread is already friendly, where it can feel stiff.
- Example: “I’ll send the agenda Tuesday unless you’d like changes first. Best regards, Alex”
6. Kind regards
Kind regards is slightly warmer than “Best regards.” It suits ongoing professional relationships where you’ve exchanged a few messages.
Best regards vs. kind regards: use “Best regards” to open a relationship and “Kind regards” once it has some warmth.
- Best for: repeat contacts and long-running projects.
- Avoid when: the email is very formal or very casual.
- Example: “Does Tuesday at 2 pm or Wednesday at 10 am ET work? Kind regards, Morgan”
7. Best
Best is efficient and neutral, and it’s common in US business email. It keeps the focus on your closing line instead of the sign-off.
- Best for: mid-thread replies and scheduling.
- Avoid when: the email delivers bad news, where one word can feel curt.
- Example: “Should I send the contract to you or to Sam? Best, Jordan”
8. Cheers
Cheers is informal and friendly. Use it once you’ve built rapport, and it works well in quick back-and-forth with peers.
- Best for: friendly peers and long-standing contacts.
- Avoid when: you’re writing to formal or very senior US contacts, where it may read as too casual.
- Example: “Shout if you need anything before Monday. Cheers, Chris”
9. Sincerely
Sincerely is for formal, official, or legal correspondence and cover letters. It’s too stiff for everyday threads.
A quick UK convention: “Yours sincerely” goes with a known recipient’s name, and “Yours faithfully” goes with an unknown recipient.
- Best for: formal requests, official letters, and cover letters.
- Avoid when: you’re in an everyday thread with a colleague.
- Example: “Please let me know if further documentation is required. Sincerely, Taylor Reed”
Quick-pick table: which sign-off fits?
Use this table when you’re short on time. Find your situation, then pick from the “Use” column.
Closing lines that prompt a reply (templates by goal)
The sign-off sets the tone, but the closing line drives the reply. These templates are built to be copied, with brackets for your details. Each one pairs with a sign-off from the list above.
Asking for a favor or help
When you’re asking for a favor or help, the ending has to make the ask feel small and the “no” feel safe. Name the effort required and give the reader an easy out.
- “Would you be open to [specific favor] by [date]? Totally understand if the timing doesn’t work.”
- “If it’s easier, a quick yes/no is all I need.”
- Name the effort: “It’s a 10-minute review” makes the favor feel small.
- Pair with: Thank you or Appreciate your help.
When you need a response
When you need an answer, give the reader a reason and a deadline. People answer faster when they know why the date matters.
- Deadline plus reason: “Could you confirm by Thursday? We lock the schedule Friday morning.”
- Binary choice: “Should I send the contract to you or to Sam?”
- Pair with: Thanks.
After a meeting or call
A post-meeting email works best when it states who does what next. If you’re the one doing the next step, say so and give a date.
- “Recap and next steps are above. I’ll send the proposal Tuesday unless you’d like changes first.”
- Pair with: Best or Thanks.
When you’re frustrated
When you’re angry, end on the resolution you want instead of the grievance. Write the draft, wait before you send, then rewrite the last line.
- “What I need is X by Y. Can we make that work?”
- Pair with: a neutral Thanks or Best.
- Skip the bare “Regards.” In a Reddit r/office thread on closing salutations, one commenter says a bare “regards,” is what they send when the person is difficult. Readers pick up on that.
Closing-line templates at a glance
This table collects the templates in one place so you can scan by goal.
Weak closing lines, rewritten
Most weak closers fail in one of two ways: they have no question, or they hand the reader extra work. Here’s what to swap in.
How to end a sales or cold email
A cold email ending works differently from an email to a colleague. The reader owes you nothing, so a low-friction ask matters most. And because you send at volume, your signature affects whether the email reaches the inbox at all.
End with one low-friction ask
Cold prospects say yes to small asks and ignore big ones. A 30-minute meeting request from a stranger is a big ask. A short question is a small one. A small ask lands best after an opener that earns it, so it pays to know how to write an intro email that sets one up.
- Interest-based close: “Worth a quick look?” or “Open to seeing how this works for [their company]?”
- Direct meeting close, for warmer or higher-intent accounts: “Do you have 15 minutes Thursday?”
- One ask only. Don’t stack “book a call, check our site, and download the deck.”
- Sign-off: Thanks or Best. Skip “Thanks in advance,” which presumes a yes.
Keep the signature text-only for outbound
Many signature guides recommend banners, headshots, and CTA buttons. That advice suits newsletters. For cold outreach, a heavy HTML signature with images and multiple links looks like marketing mail and can hurt inbox placement.
To set up a cleaner outbound ending:
- Write the signature in plain text: name, title, company, and one optional link.
- Remove images, logos, banners, and tracking-heavy social icons.
- Send from a separate sending domain, never your primary domain.
- Warm that domain for about 2 to 3 weeks and ramp volume gradually before full sending.
If you run outbound at volume, signature and domain details are only part of the work. Key Outreach sends text-only email from dedicated sending domains, never the client’s primary domain, with domain warm-up built into the first weeks of onboarding. First emails typically go out around week 4.
It’s the same deliverability-first outbound program behind Key Outreach’s #1 Agency on SmartLead 2025 standing, which reflects the highest reply rates among 5,000+ SmartLead users.
Plan the close of every follow-up, too
Repeating “just bumping this up” gives the reader no new reason to answer. Change the closing line on every touch so each follow-up adds something. Apply that rule across the whole sequence, alongside other email prospecting tips for spacing and targeting.
- Follow-up 1, add value: “Here’s a 2-line example of how [similar company] uses this.”
- Follow-up 2, ask a different question: “Is this a priority this quarter, or should I check back later?”
- Final email, exit politely: “I’ll close the loop here. Reply ‘later’ if timing changes.”
A good ending only pays off if someone answers
The best closing line creates replies, and replies need fast, human follow-through to become meetings. That’s where many programs leak pipeline.
If replies are sitting in an inbox nobody owns, a “sure, let’s talk” goes cold. Key Outreach’s managed program covers ICP, list building, copywriting, sending, inbox monitoring, and meeting booking, so a positive reply turns into a calendar invite.

Formal vs. informal email endings
Choosing between a formal and an informal ending comes down to three things: the relationship, the industry, and the tone of the other person’s last message. Match those and you’ll rarely miss.
Email sign-offs and closings to avoid
Some endings confuse the reader, sound passive-aggressive, or look unprofessional. Cut these from your drafts.
- No sign-off at all in a first email. It reads as abrupt.
- “Sent from my iPhone” as the only ending.
- Bare “Regards,” in a tense thread. It reads as cold.
- “Thanks in advance” on a first-touch cold email. It presumes a yes.
- “Love,” “xoxo,” or “Blessings” in business email.
- Multiple asks in the closing line.
- “Let me know your thoughts” with no deadline or specific question.
- Heavy HTML signatures on outbound emails (see the cold email section above).
Email signature checklist
Run your signature template through this checklist once, then save it so you never rebuild it.
- Full name
- Job title and company
- One phone number or one link (not five)
- A lighter version for replies inside threads
- Plain text for cold or outbound emails
- Mobile test: the signature shouldn’t take up more space than the message
Want more replies? Key Outreach runs your outbound
A strong ending comes down to one ask, the right sign-off, and a clean signature.
Key takeaways:
- Run Ask → Thank → Name. End with one answerable ask, a sign-off that matches the relationship, and a lean signature. Mirror the reader’s formality, and warm up as the thread does.
- Pick by context. Default to “Thanks” or “Best regards,” use “Thank you” for favors, and save “Thanks in advance” for warm relationships, never first-touch cold email.
- Rewrite vague closers. Swap “Let me know your thoughts” for a deadline, a binary choice, or a yes/no question, and name the effort so the ask feels small.
- Protect deliverability. Keep cold email signatures plain text with one link, send from a warmed dedicated domain, and give every follow-up a different closing line.
Key Outreach runs your outbound end-to-end (ICP, lists, copy, sending, and booked meetings) so your team can focus on closing. Book a call to see how we’d build predictable pipeline for your business.
FAQs
What is the most professional way to end an email?
Finish with a clear closing line, then sign off with “Best regards” or “Thanks.” Use “Best regards” for first contact with clients or executives. Use “Thanks” once you’re in an active thread. Follow with a short signature that includes your name, title, and company.
How do you end an email when asking for a favor?
Make a specific ask with a deadline, name how little effort it takes, and offer an easy out. Then sign off with “Thank you” or “Appreciate your help.” For example: “Would you be open to a 10-minute review by Thursday? Totally understand if the timing doesn’t work.”
Is “Best” too casual?
No. “Best” is fine for most US business email, especially mid-thread. For a first email to a client, partner, or executive, use “Best regards” instead. If you’re delivering bad news, choose a warmer closer because “Best” alone can feel curt.
Should I use “Thanks in advance”?
Use it with existing relationships and small, reasonable asks. Avoid it with cold prospects, because it presumes a yes. For first-touch outreach, end on a low-friction question and sign off with “Thanks” or “Best.”
How do you end an angry email professionally?
End on the outcome you need, not the grievance. Write the draft, wait before you send, then close with: “What I need is X by Y. Can we make that work?” Sign off with a neutral “Thanks” or “Best,” and skip the bare “Regards.”
What’s the difference between a sign-off and a signature?
The sign-off is the closing word or phrase before your name, like “Thanks” or “Best regards.” The signature is the block below it with your name, title, company, and contact details. You need both, but they do different jobs.
