Is your email sign-off an afterthought? Teams often obsess over subject lines, personalization, and send timing, then treat the final line like filler. That's a mistake. The last words in your message often shape the emotional aftertaste of the email, and that affects whether a prospect replies, whether a customer feels taken care of, and whether your brand sounds polished or forgettable.
Closing email phrases do more than signal the end of a message. They frame your ask, soften a technical update, reinforce your brand voice, and help the recipient understand what happens next. In day-to-day email marketing and outbound work, I've seen strong emails lose momentum because the sign-off felt cold, vague, or oddly pushy. I've also seen plain messages work because the close matched the context.
There's also a deliverability angle people skip. A polished closing won't rescue a bad list, but it does support trust. When your wording is clear, your signature is consistent, and your request is easy to understand, recipients are less likely to hesitate, ignore, or mark the message as unwanted. That matters if you care about long-term sender reputation.
If you want a broader framework for professional sign-offs, this email closing guide for ecommerce brands is useful context. For now, let's get practical and break down the closing email phrases that fit real business situations.

- From Closing Phrase to Clean List The Final Word
1. Best regards
“Best regards” is the safe default that rarely creates problems. It sounds professional, respectful, and neutral enough for almost any business setting. If you're sending account verification updates, policy notices, or campaign reports to an enterprise client, this phrase keeps the tone steady.
That matters when the message itself carries weight. A billing correction from Stripe, an account security update from HubSpot, or a verification summary from CleanMyList shouldn't sound chatty. The recipient needs clarity first, personality second.
Where it works best
Use “Best regards” when the relationship is new, the stakes are formal, or the email may be forwarded internally. It travels well across departments and seniority levels, which is why legal, finance, customer operations, and enterprise sales teams still rely on it.
A few strong fits:
- Verification results: A platform confirms which uploaded contacts are safe to mail.
- Technical notices: A SaaS support team explains a settings change or integration issue.
- Client reporting: An account manager sends a monthly performance summary to a procurement-heavy organization.
Practical rule: If the email might end up in a forwarded thread with executives, “Best regards” is usually safer than trying to sound clever.
The trade-off is that it won't add warmth on its own. If the rest of the message is dry, “Best regards” can feel distant. Fix that with the sentence before the sign-off. A line like “Please reply with any questions about the verification file” gives the recipient direction. The sign-off then does its real job, which is to end the email cleanly.
For automated or semi-automated messages, this is one of the strongest choices. It pairs well with a complete signature block, company logo, support email, and product links. If personalization is limited, neutrality helps.
2. Thanks
“Thanks” works when the recipient has already done something, or when you're acknowledging time and attention without sounding stiff. It's short, modern, and easy to use in SaaS, startup, and growth-team communication. That's one reason it shows up so often in onboarding and support.
It also performs well in real outreach data. In Boomerang's analysis of over 350,000 email threads, the closing phrase “Thanks” reached a 63.0% response rate, outperforming several more neutral alternatives in the same dataset, as reported in this breakdown of email closing performance.
Why it works
Gratitude changes the feel of the request. “Thanks” tells the reader you recognize their effort, even if that effort is reviewing the message. In practical terms, it fits nicely after actions like uploading a CSV, requesting re-verification, joining a trial, or sending feedback.
A few examples:
- A CleanMyList onboarding email after a user uploads their first file.
- A reply to a feature request in Intercom.
- A confirmation email from Notion after a workspace admin completes setup.
For this phrase to land well, the body needs context. “Thanks” alone can sound lazy if the email doesn't earn it. Write the line before it with more specificity, like “Thanks for uploading your list. We're processing it now and will flag risky addresses in the results file.”
If you need help shaping that structure, this guide on how to compose a business email is a practical companion.
A good “Thanks” closes a loop. A weak “Thanks” tries to replace substance.
This is also where teams overdo friendliness. If you're delivering bad news, such as a rejected import or a blocked domain setting, “Thanks” can still work, but only if the email explains what happened and what the recipient should do next.
3. Cheers
“Cheers” is useful when your brand voice is informal and your audience expects human, relaxed communication. In tech, developer tooling, creator businesses, and some startup support teams, it can feel natural. In enterprise procurement, healthcare, or compliance-heavy industries, it can feel off.
That difference matters more than people think. Closing email phrases aren't universally good or bad. They're only right or wrong for the reader in front of you.
Here's the tone this phrase carries:
When “Cheers” helps
Use it in one-to-one support notes, educational content, and low-friction conversations where approachability helps more than formality. A developer advocate answering an API question, a growth lead sharing deliverability advice, or a customer success rep sending a quick workaround can all use “Cheers” comfortably.
Good fits include:
- Developer documentation follow-up: “Your API key is active. If the webhook test fails again, send over the request ID. Cheers,”
- Casual support reply: “I've reset the import settings on your account. Try again when you're ready. Cheers,”
- Growth newsletter note: “You'll get cleaner reporting if you suppress role-based addresses before the next send. Cheers,”
The risk is obvious. “Cheers” can reduce perceived seriousness. If the issue involves account access, billing disputes, or a deliverability problem that could affect revenue, a more grounded sign-off usually plays better.
Indeed and Scribe-mail both stress the importance of the closing sentence before the sign-off, especially when you need action. Their practical point is simple: a clear next step does more work than a stylish final word, as discussed in this guide to effective professional email closings.
4. Looking forward to hearing from you
This phrase is common because it signals openness without sounding as assumptive as stronger future-focused language. It invites a reply, which makes it useful in sales outreach, demo follow-ups, and partnership emails. If you've asked a direct question or proposed a next step, it gives the thread momentum.
Still, this isn't a phrase to scatter everywhere. It works best when a response is both realistic and appropriate.
Use it when the ask is clear
A sales rep at CleanMyList following up after a deliverability consultation might write, “I've attached a sample verification workflow for your outbound list. Looking forward to hearing from you.” That works because the recipient has enough information to respond.
It also fits:
- Post-demo recap emails
- Partnership outreach to ESPs or agencies
- Consultative outbound to ecommerce operators dealing with list decay
The most common mistake is using this phrase after a vague email. If the recipient doesn't know what you want, “Looking forward to hearing from you” sounds generic. The close should follow a specific ask such as replying with the file, choosing a meeting time, or confirming whether the workflow fits.
If your close asks for nothing, this phrase won't create momentum on its own.
There's another trade-off here. Forward-looking closings can feel subtly transactional in cold outreach, especially if the relationship is brand new. That's why tone matters. The University of Maryland distinction cited in this analysis of three-word email closings is useful in practice. “Thank you” often feels professional because it acknowledges value without demanding action, while “thanks in advance” can feel more prescriptive in some contexts.
For first-touch outbound, I often prefer to make the ask very plain and let the final line stay modest.
5. Talk soon
“Talk soon” works when there's an active relationship and another touchpoint is already likely. It sounds warm, confident, and familiar. Used well, it tells the recipient this isn't a one-off interaction. Used badly, it sounds fake.
That's why support and customer success teams can use it more freely than cold sales teams. If a customer has an open ticket, an upcoming onboarding call, or a scheduled check-in, “Talk soon” feels natural.
Where it fits
A few real scenarios make this easy to judge:
- A customer success manager at Klaviyo confirms next week's account review.
- A CleanMyList support rep resolves one issue and notes they'll follow up after the next verification run.
- A community manager wraps up a thread with a user who's testing a new feature.
The phrase gets stronger when you anchor it to time. “Talk next week” or “Talk on Thursday after your upload finishes” sounds more concrete than the floating version. That specificity also helps trust. People notice when you promise contact and then disappear.
One caution. Don't use “Talk soon” in broad campaigns or one-to-many marketing emails unless the brand voice is highly conversational and the audience expects it. In a lifecycle sequence sent at scale, it can read like forced intimacy.
A better pattern is to reserve it for customer conversations where an actual human will likely reappear in the thread. In those settings, it helps build continuity, and continuity is one of the easiest ways to make service emails feel more premium.
6. Best
“Best” is efficient. It closes the email without adding much tone one way or the other. In fast-moving conversations, that's exactly what you want. Engineers, product managers, and support teams use it because it gets out of the way.
I like “Best” in threads where the body already carries the emotional weight. If the message is helpful, clear, and direct, the sign-off can stay minimal.
Why brevity works here
Internal updates, quick bug replies, and short technical answers don't need a decorative ending. A support engineer at Postmark can answer an SMTP configuration question in four lines and close with “Best” without sounding cold. A growth lead can send a revised suppression file and do the same.
Use it when:
- The thread is moving quickly: Long sign-offs slow the rhythm.
- The content is already specific: The body explains the decision, fix, or next step.
- The recipient knows you: Familiarity does the warmth work for you.
“Best” becomes a problem when teams use it to cover for abrupt writing. If the email says, “Need this today. Best,” the sign-off won't soften the demand. The sentence before it still determines the tone.
That's the larger lesson with closing email phrases. The close doesn't carry the whole interaction. It amplifies what came just before it. In support, for example, “I've rechecked the file and removed the invalid entries. Let me know if you want me to review the catch-all segment too. Best,” feels useful and complete. The same sign-off after a vague or blunt message feels dismissive.
For technical and operational email, concise often beats charming.
7. Warm regards
“Warm regards” adds humanity without drifting into casual territory. It's more personal than “Best regards,” but it still belongs in professional settings. That makes it strong for account management, onboarding, and relationship-led retention work.
If someone is trusting you with their sender reputation, deliverability setup, or subscriber data, a little warmth helps. You don't need to sound like a friend. You do need to sound like a person.
Best use cases
Customer success teams are the natural home for this phrase. Think of a success manager helping a retailer clean a neglected subscriber file before a major campaign, or an onboarding specialist guiding a media publisher through a new validation workflow.
It also fits:
- Thank-you notes after a productive call
- Renewal conversations with established accounts
- Personalized follow-ups after a problem has been resolved
The phrase works best when the email includes something unmistakably personal, such as a reference to the customer's workflow, recent campaign, or concern.
The downside is that “Warm regards” can feel performative in automated sends. If the message is clearly templated and impersonal, the warmth reads as borrowed. That's why I'd keep it for real account communication, founder notes, or lightly personalized lifecycle messages where a named sender is doing actual relationship work.
Used carefully, this phrase helps a brand sound attentive. That's valuable in a category like email verification, where many buyers compare tools on features and forget that confidence often comes from communication quality.
8. Yours truly
“Yours truly” isn't common, which is exactly why it can work. It feels personal, slightly traditional, and more accountable than modern default sign-offs. I wouldn't use it for routine support traffic, but I would use it when a real person is deliberately stepping forward.
Founder emails are the clearest example. If a founder at CleanMyList writes to early customers about product direction, data privacy, or a major workflow improvement, “Sincerely” can underline that the note came from an individual, not a marketing machine.
Why it still has a place
This phrase suits messages where authorship matters. A leadership update, a personal thank-you to a referral partner, or an apology email where one person is owning the issue can all benefit from the extra sincerity.
Examples:
- A founder following up after meeting a potential agency partner
- A handwritten-style thank-you note to a long-term customer
- A leadership email explaining a product decision that affects users directly
The risk is obvious. If the email isn't genuinely personal, the phrase can sound theatrical. It needs specific details, a named sender, and a reason for being more individual than usual. Otherwise “Warm regards” or “Best regards” will do the same job with less friction.
I'd also avoid using this phrase in highly transactional messages. Password resets, invoice notices, and verification status updates should stay simpler. “Yours truly” belongs where trust is being built person to person.
9. Keep it clean
Most sign-offs are generic. “Keep it clean” is not. For CleanMyList, it's a branded closing that reinforces the product promise every time someone reads it. That kind of phrase can be effective when it naturally reflects what the company does.
Brand-specific closing email phrases work best when they're easy to understand without explanation. “Keep it clean” passes that test because clean lists, lower bounce risk, and better sender reputation are central to the service.
Here's the visual logic behind the phrase:
Branding without sounding forced
This sign-off makes the most sense in newsletters, educational campaigns, webinars, community posts, and customer success communication. It gives the brand a distinct voice while keeping the message tied to the value proposition.
Strong fits include:
- Marketing newsletter: A weekly note about bounce prevention and list hygiene.
- Onboarding emails: A welcome sequence explaining how verification protects campaigns.
- Community replies: Short responses from the brand on deliverability topics.
It helps if the rest of the email supports the line. If you're talking about typo prevention, stale contact removal, or suppression strategy, “Keep it clean” feels earned. If the email is about pricing updates or legal terms, it may feel gimmicky.
A brand phrase also works better when users understand the underlying operational reason. This article on how to clean an email list gives that context well.
For deliverability, branded closings won't move technical metrics by themselves. But they do help consistency. Consistent sender identity across signatures, domains, and message tone makes your communication easier to recognize. That recognition supports trust, and trust supports long-term inbox performance.
10. Let's make your emails count
This phrase is outcome-driven. It doesn't just end the email. It points to the result the recipient wants. For CleanMyList, that's a strong match because the product sits close to business outcomes like cleaner campaigns, fewer wasted sends, and more confidence before launch.
It works best in sales, onboarding, and educational emails where the body already talks about impact. If the message explains why list verification matters before a big campaign or before cold outreach begins, the sign-off reinforces the point.
Here's the kind of business-focused framing this phrase supports:
Good for value-led communication
A few natural scenarios:
- A sales email to a retailer preparing a holiday send
- An onboarding note explaining how verification fits into campaign prep
- A customer success message encouraging a re-check of an aging list before a relaunch
This phrase is aspirational, so it needs proof or at least concrete logic in the body. If the email only says “we can help your deliverability,” the sign-off may sound like a slogan. If the email explains the workflow, such as upload, verify, review flagged addresses, then export a safer list, the phrase feels grounded.
It also pairs nicely with practical education. A piece on how to improve email deliverability creates the right context for this kind of closing.
One note of caution. Don't overuse motivational language in support emails. Someone waiting on a file export issue doesn't want a mission statement. They want a fix. This phrase belongs in moments where growth, outcomes, and forward motion are already central to the conversation.

From Closing Phrase to Clean List The Final Word
Choosing the right closing phrase looks like a minor writing decision. In practice, it signals judgment. It tells the recipient how formal you are, how much confidence you have in the ask, how you see the relationship, and whether your brand sounds generic or considered. That's why strong email teams don't pick sign-offs randomly. They match them to the goal of the message.
A support reply needs reassurance and clarity. A sales follow-up needs forward motion without pressure. A customer success note should sound personal enough to build trust. A branded newsletter can carry more voice, but only if the phrase still fits the promise behind the product. The best closing email phrases don't just sound good. They support the job the email is trying to do.
There's another layer that matters just as much. Deliverability starts before the sign-off. If your list is stale, packed with typos, or full of risky addresses, even the most polished closing won't save the campaign. Recipients won't see your careful phrasing if the message lands in spam or gets blocked before inbox placement. That's where list hygiene stops being a back-office task and becomes part of communication quality.
CleanMyList sits right at that intersection. You can write a sharper email, use a clearer CTA, and choose a better sign-off. You should. But you also need to verify the contacts behind the campaign, protect your sender reputation, and remove the addresses most likely to create bounce or trust problems. Strong copy and clean data belong together.
That combination matters for every team this article speaks to. Startups need quick, credible outreach. Ecommerce brands need cleaner campaign sends before promotions. Newsletter operators need consistency. Sales teams need confidence that their message is reaching a real person. Developers implementing validation at signup need to stop bad data before it enters the system in the first place.
If you want examples of follow-up structure that pair well with the sign-offs above, these Machine Marketing sales email templates are a helpful reference point.
The final word is simple. Pick closing email phrases with intent, not habit. Then make sure the list behind those emails is worth sending to.
