Politeness in a request comes from clarity, relevance, and respect for the reader's time, not from ceremonial phrasing. The test of a good request is simple: after one read, can the reader tell what you want, why them, by when, how much work it is, and how to reply? If any of those is missing, the reader has to do the work of figuring it out, which is exactly the burden polite wording is supposed to remove. Three habits carry most of the weight.
- Put the ask in the first few lines, and in the subject. Background is only useful after the reader knows what they are being asked to do. "Could you approve the attached Acme discount by Thursday 16:00 CET?" belongs before the context, not after it.
- Give the deadline structure. Write the date, time, timezone, reason, and fallback. Replace "ASAP" and "EOD" with a concrete time, and avoid "tomorrow morning" for global teams unless everyone knows whose morning.
- Leave room for no without weakening the ask. Good optionality is a useful alternative path ("if you are not the right person, could you point me to the owner?"), not vague politeness. Use "if you have time" only when the request is genuinely optional.
Answer the reader's silent questions
Before replying, the reader is quietly working through: What do you want from me? Why me? By when? How much work is this? What should I pay attention to, and what can I ignore? How should I reply? What happens after I reply? What if I cannot do it? A strong request answers these before they are asked. When the reader can see the ask, the scope, the deadline, the reply format, and the way out, saying yes is easy.
Bound the work
"Could you review this?" is usually too broad. Review can mean skim, approve, fact-check, rewrite, or take responsibility for the whole document. A scoped review request names the object, the lens, the depth, and what not to review: "Could you review pages 2-3 of the proposal for pricing accuracy by Thursday? No need to edit wording or check the legal terms. Comments in the doc are ideal; 'pricing looks fine' by email is also enough." That makes the effort visible and lets the reader estimate the time before they commit.
Match the request to the reader
For executives and managers, ask for a decision, not vague review, and state your recommendation and the tradeoff: "I recommend Option B because it preserves the renewal date; the tradeoff is a two-point margin reduction. Please reply 'approve Option B' or 'hold' by Thursday 16:00 CET." For peers, show scope and respect workload. For clients, ask for client-owned input, not broad quality control. For vendors, be exact about deliverable, format, reference numbers, deadline, and the dependency: "Please send the revised invoice with the corrected PO number by Wednesday 12:00 ET; we cannot process payment until the PO number matches the contract record."
Separate multiple asks, and skip the false smallness
If there are several asks, label the primary action and split the rest: main action, decision needed, context, already approved, optional. Split into separate emails when different people own the actions, the deadlines differ, or one item is sensitive. And do not shrink a real ask to seem polite: "just a tiny favor" for a full review sets a false expectation. Name the work honestly, then make it easy to do.
