Best Email Sign-offs: 60 Ways to Close a Professional Email

The last two words of your email carry more weight than you might expect. They set the tone for what comes next, whether that is a reply, an action, or simply how the recipient remembers the interaction. This guide covers 60 email sign-offs organized by situation, from formal closes to genuinely funny ones, plus the ones that have stopped working and why.

Why Your Email Closing Matters

Most people spend ninety percent of their email-writing energy on the subject line and the body, then add "Best" without thinking. But how you close an email signals professionalism, warmth, urgency, and relationship level all at once. The wrong sign-off in a formal negotiation reads as too casual. The wrong one in an internal Slack-style email reads as stiff. The right closing lands without the recipient noticing it — it just feels right.

A few principles that apply across all categories:

• Match the relationship: Formal clients get formal closings. Colleagues who text you get something warmer.
• Avoid autopilot: "Best regards" used for every email in every context starts to feel like a form letter.
• The comma matters: "Sincerely," and "Sincerely" are slightly different in feel. The comma is standard; dropping it reads more casual.
• Your name belongs on the next line: Don't close with "Best, [Name]" crammed into a single line.

Formal Email Sign-offs

Use these for job applications, first-time contact with senior stakeholders, legal correspondence, or any situation where the relationship is new and the stakes are real.

1. Sincerely,
2. Regards,
3. Best regards,
4. With appreciation,
5. Respectfully,
6. With respect,
7. Yours sincerely,
8. Yours faithfully, (use when you do not know the recipient's name)
9. Faithfully,
10. With kind regards,

When to use formal sign-offs: Initial client outreach, board-level correspondence, vendor contracts, formal complaints, anything with a legal dimension. They communicate seriousness without warmth, which is often exactly right.

Professional but Approachable Sign-offs

These work for most business email: colleagues you have not met, clients you know well, external stakeholders you interact with regularly.

11. Best,
12. Thanks,
13. Thank you,
14. Many thanks,
15. All the best,
16. Warm regards,
17. Warmly,
18. With gratitude,
19. Appreciate it,
20. Looking forward to speaking,
21. Talk soon,
22. Until next time,
23. Have a good week,
24. Kind regards,
25. With thanks,

A note on "Best": It has become the default professional sign-off in most industries and is completely serviceable. It is warm without being presumptuous, brief without being abrupt. If you are unsure what to use, "Best," is the safe choice. That said, using it in every single email regardless of context is the equivalent of a form signature — it says nothing about the relationship.

Friendly and Casual Sign-offs

For internal email, people you work closely with, teammates, or anyone where professional formality would feel jarring.

26. Thanks again,
27. Cheers,
28. Take care,
29. Have a great one,
30. Catch you later,
31. Until then,
32. Talk to you soon,
33. See you Thursday,
34. Stay well,
35. Good luck with it,
36. Rooting for you,
37. More soon,

When to use casual sign-offs: These work best when the relationship would make a formal closing seem performative. "Sincerely" to a colleague you see every day reads as ironic. Casual closings work for internal project updates, replies within a thread where formality has already relaxed, and any situation where the relationship is warm and established.

Fun and Memorable Sign-offs

Used carefully, a distinctive sign-off becomes part of how people remember you. Used carelessly, it reads as trying too hard. The ones below work best for creative industries, startups, and relationships where personality is welcome.

38. Onward,
39. Stay curious,
40. Go make something,
41. To good work,
42. In it with you,
43. Here to help,
44. With enthusiasm,
45. Energetically yours,
46. To the next thing,
47. Ever forward,
48. More to come,

Fun email sign-offs tend to work when they are authentic. If you are genuinely enthusiastic, "With enthusiasm," is not performative. If it is your brand voice, it lands. The failure mode is a clever sign-off that does not match the email's tone — a lighthearted close on a serious message reads as tone-deaf.

Situation-Specific Closings

Some situations call for a sign-off that acknowledges the context directly.

After asking a favor: 49. Thanks for considering it, 50. I appreciate whatever you can do,

After a difficult conversation: 51. With appreciation for your candor, 52. Thank you for your directness,

When things are moving fast: 53. More updates shortly, 54. Will follow up by end of day, 55. Watch for my next note,

When closing a deal or project: 56. Looking forward to working together, 57. Excited for what is next,

When wrapping up a relationship or thread: 58. It has been a pleasure, 59. Wishing you all the best from here, 60. Take good care,

The Sign-offs That No Longer Work

Some closings have been used so often, often by AI tools generating generic professional email, that they have lost meaning. They do not actively harm your email, but they signal nothing about you and the relationship.

Overused to the point of invisibility:

• "Best regards" in every email to every contact
• "I hope this email finds you well" (this is technically an opener, but it pairs with generic closings)
• "Please let me know if you have any questions"
• "Do not hesitate to reach out"

None of these are wrong. They are just empty. If your recipient sees your name in their inbox and could predict your sign-off, it is doing no work for you.

Actively problematic:

• "Yours truly," in a business context with someone you do not know well (implies intimacy that is not there)
• "XOXO" in any professional setting
• "Sent from my iPhone" as a deliberate affectation (people know)
• No sign-off at all in a first email (reads as abrupt)

Synonyms for "Best Regards"

If you use "Best regards" by default and want to vary it, here is a direct substitution list:

Alternatives to "Sincerely"

"Sincerely" is correct and formal, but it can feel dated in some professional contexts. If you want to maintain formality without sounding like a letter from 1985:

• Respectfully,
• With appreciation,
• Yours truly, (slightly warmer)
• Regards,
• Best regards,
• Warmly, (one step less formal)

The Sign-off and the Signature Block

Your sign-off and your email signature are different things. The sign-off is the closing word or phrase (Regards, / Best,). The signature block is your name, title, contact details, and any other information that follows. They work together: a warm sign-off paired with a dense corporate signature block can create tonal dissonance. A casual sign-off with no signature at all in a first email leaves recipients without context.

A functional signature block includes:

• Your name
• Your title and company
• One phone number and one website
• Nothing else, unless you have a specific reason for adding it

Long signature blocks with motivational quotes, social media links, legal disclaimers, and a logo carousel are read by no one.

Your Sign-off Is Part of Your Voice

The best sign-offs are the ones that fit naturally with how you write the rest of the email. If your emails are direct and brief, "Thanks," works. If they are warmer and more relationship-oriented, "Looking forward to speaking," earns its length. If you are in a creative field where personality is a professional asset, something memorable is worth trying.

If you use AI to draft email, the sign-off is often where generic voice shows up most clearly. The model defaults to the most statistically common professional close, which is also the least distinctive one. A system that has learned from your actual sent emails will close the way you close, not the way average professional email closes.
