Good alternatives to “Let me know if you need more information” are “I’m happy to share more detail if it would help”, “If anything is unclear, just let me know” and, in a formal email, “Please let me know if you require any further information.” Even better is an offer of something specific: “I can send the full survey results if you’d like to check the figures.”
Below, the alternatives are sorted by how formal they are, with notes on when each one fits, which popular versions can sound stiff or curt, a few grammar points that trip people up (including “contact Ollie or myself”), complete email endings, and a short practice set.
Quick picker
| Writing to… | Try |
|---|---|
| a client, a manager you don’t know, an official body | Please let me know if you require any further information. |
| a customer | If you have any other questions, we’re happy to help. |
| a colleague | Happy to go into more detail if that’s useful. |
| a teammate or friend | Shout if you need anything else. |
| someone you sent a document to | I can walk you through any part of it on a quick call. |
| a teacher or professor | I’d be glad to provide more detail on any part of the proposal. |
| someone who must reply | Could you let me know by Thursday whether you need the full report? |
Formal alternatives
Use these with clients, senior people you don’t know well, job applications, and official letters.
- Please let me know if you require any further information. The safest formal version. Require is more formal than need; further is a touch more formal than more.
- Should you need any further information, please contact me. The “should you” opening means “if you” and sounds polished. It suits letters and cover letters.
- I would be happy to provide any additional details you may need. Puts the offer in your own voice, which reads warmer than a bare instruction.
- If any further information would be helpful, please get in touch. Good when you are not sure the reader needs more at all.
- Please do not hesitate to contact me if you have any questions. Very common and perfectly polite, but so common that many readers skim past it. Our page on alternatives to “don’t hesitate to contact me” has fresher versions.
Everyday work emails
For colleagues, regular clients and most internal email, plain and friendly beats formal.
- Happy to share more detail if it would help.
- If anything is unclear, just let me know.
- Let me know if you’d like more background on any of this.
- I can go into more detail on [the costs / the timeline] if that’s useful.
- Any questions, just ask. (short and common in British English)
- Do let me know if you need anything else. The extra do adds warmth; it sounds more British than American.
Casual and friendly
- Shout if you need anything else. (British and Australian; friendly, not literal)
- Give me a shout if you get stuck.
- Ping me if you need more. (office and tech slang for a quick message)
- Holler if you need anything. (American, very casual)
- Happy to explain more, just ask!
Keep these for people you already know. In a first email to a client, “holler” or “ping me” can look careless.
In chat messages and out loud
Work chat (Slack, Teams, WhatsApp) is shorter than email, and a long formal closing looks out of place there. One short line is enough:
- Happy to add more context if needed.
- More detail in the doc, but ask if anything’s unclear.
- Can share the numbers if useful. (dropping “I” is normal in chat, not in email)
Spoken at the end of a presentation, meeting or class, the offer works best as a direct invitation followed by a pause, so people have time to take it up:
- “I’ve kept the figures brief, but I’m happy to go into any of them now.”
- “What would you like me to say more about?” An open question gets more replies than “Any questions?”, which many audiences answer with silence.
- “If something comes up later, my email is on the last slide.”
Where it goes in an email
The offer belongs in the last line of the body, just before the sign-off (“Best regards”, “Thanks”). Three habits make it work better:
- Use it once. If the email already says “let me know if you have any questions” earlier, don’t repeat the offer at the end.
- Put any action you need first. If the reader must do something (sign, approve, choose a date), say that before the offer of more information, or the request gets lost.
- Don’t let it replace the answer. If you know the reader will need a detail, include it now rather than offering it later. The offer is for extras, not for missing basics.
Offer something specific instead
A general offer of “more information” asks the reader to work out what else exists and whether it is worth asking for. Naming the extra material is more useful and more likely to get a reply:
| Instead of… | Try |
|---|---|
| Let me know if you need more information. | I have the full breakdown by region if you’d like to see it. |
| Let me know if you need more information. | If it helps, I can send last year’s figures for comparison. |
| Let me know if you need more information. | The attached FAQ covers delivery and returns; for anything else, just reply here. |
| Let me know if you need more information. | If a quick call would be easier than email, I’m free Tuesday or Wednesday afternoon. |
Phrases to use with care
| Phrase | The problem | Better |
|---|---|---|
| Let me know if you’re still confused. | Suggests the reader is slow, and that the problem is them, not your explanation. | If any part isn’t clear, let me know. |
| Please advise. | It asks the reader to tell you something; it does not offer help. “If you have further queries, please advise” mixes the two. | Use “please advise” only when you need their decision: “Please advise which option you prefer.” |
| Kindly let me know… | Normal and polite in Indian, Nigerian and some other Englishes, but it can read as stiff or even impatient to British and American readers. | Please let me know… |
| I remain at your disposal. | A word-for-word match for French and Spanish formulas; in English it sounds old-fashioned. | I’d be happy to help with anything else. |
| Feel free to reach out. | Fine, but heavily used in business email and disliked by some readers. | Just reply here if you need anything. |
| Your inquiry is welcome should you have further questions. | Grammatical, but no native speaker writes it. | If you have more questions, I’m happy to answer them. |
Grammar points
“Information”, never “informations”
Information is uncountable in English: “more information”, “any further information”, “a piece of information”. Never “informations” or “an information”. The same goes for advice and feedback. Detail can be both: “more detail” and “more details” are both fine.
“Contact Ollie or me”, not “Ollie or myself”
People reach for myself because it feels more polite, but it is only correct when you are also the subject of the sentence (“I emailed myself a copy”). Test it by removing the other person: you would write “contact me”, so write “Please contact Ollie or me”. “Ollie and I will be happy to help” is right because there I is a subject.
“Further” or “more”?
Both work: “further information” is slightly more formal, “more information” is plainer. Avoid stacking both: “any further more information” is wrong.
No question mark
“Let me know if you need more information.” is a request, not a question, so it ends with a full stop. “Do you need more information?” is a question.
The “should you” pattern
“Should you require further information” means “if you require further information”. Keep the verb in its base form: “should you require“, not “should you requires” or “should you required“.
Complete email endings
To a new client:
I’ve attached the revised quote with the delivery dates we discussed. Should you require any further information, please let me know.
Kind regards,

To a colleague:
Here’s the summary for Friday’s meeting. I’ve left out the line-by-line costs to keep it short, but I can send them if you’d like to check anything.
Thanks,
Sam
To a customer:
Your replacement has been dispatched and should arrive within three working days. If you have any other questions about your order, just reply to this email and we’ll be happy to help.
To a professor:
I’ve attached my research proposal. I’d be glad to provide more detail on the method or the sources if that would help.
For the opening of the same emails, see alternatives to “I hope this email finds you well”.
How it differs from similar closings
- “Let me know if you need more information” offers more of what you have just sent: details, data, background.
- “Let me know if you have any questions” invites the reader to ask about anything they did not understand. It is the better choice after instructions or a long explanation. There is a separate list of ways to say “let me know if you have any questions”.
- “Let me know if you need anything” offers general help, not just information, and suits customer service or someone settling into a new job.
- “Let me know” on its own usually asks for a decision or a reply (“Let me know which date works”).
Pick the one that matches what you are actually offering. If you need a reply, ask a direct question with a date instead of an open offer.
Practice
Choose or fix the closing.
- First email to a law firm’s partner: “Holler if you need more” or “Should you require any further information, please let me know”?
- Correct the grammar: “Please contact Mia or myself if you need more informations.”
- Make it more useful: “Let me know if you need more information.” (You have a spreadsheet of last year’s sales.)
- Rewrite so it doesn’t blame the reader: “Let me know if you’re still confused.”
- Correct: “Should you required any further information, please advise.”
Answers: 1. The second; “holler” is too casual for a first formal email. 2. “Please contact Mia or me if you need more information.” 3. For example: “I have last year’s sales by month in a spreadsheet if you’d like to compare.” 4. “If any part isn’t clear, let me know and I’ll explain it differently.” 5. “Should you require any further information, please let me know.” (base form after should you; “please advise” asks for their decision, not for a request for help.)

No. It is polite and common. It can feel automatic, though, so an offer of something specific often works better.

Both are correct. “Further” sounds slightly more formal. Never use “informations”.
