Common Mistakes to Avoid
1. Using “Further Assistance” Too Often
“Further assistance” is perfectly correct, but repeating it in every email can sound formulaic.
Instead, vary your language:
Let me know if you need anything else.
or:
Please let me know how I can support you.
2. Being Too Formal
A sentence such as:
I remain at your disposal should you require any further assistance.
may sound unnatural in a quick message to a coworker.
For an internal email, use:
Let me know if you need anything else.
3. Being Too Casual With Clients
Avoid overly casual wording when communicating with a new client.
Instead of:
Just give me a shout if you need anything.
choose:
Please feel free to reach out if you need anything else.
4. Offering Help Without Saying What Kind
Sometimes “further assistance” feels vague.
If you know what the recipient might need, be specific.
Instead of:
Let me know if I can help.
try:
Please let me know if you need any clarification regarding the pricing.
Specific language is often more useful.
5. Overusing “Please”
Using “please” once is usually enough. Avoid stacking polite phrases:
Please feel free to please let me know if you need anything else.
A cleaner version is:
Please feel free to reach out if you need anything else.
