How do I shorten an email without losing the important details?

Don’t start by trimming individual words. Start by deciding what the email must accomplish. In one sentence, finish: “After reading this, the reader should know, decide, or do ___.”

Then protect the information needed to accomplish that purpose: the relevant situation, the request or decision, any deadline or constraint, and the next step. A detail is important if removing it could change the reader’s understanding, decision, or action. Repetition and background that do not affect those things are good candidates to cut.

Keep the smallest amount of context that makes the request understandable. Usually, that means stating the situation in a direct opening sentence, then moving to the point. You can remove the history of how you reached the situation unless the recipient needs it to make a decision or take the right action.

For example, assume this is a hypothetical email asking a colleague to review a draft. A long explanation of when you began writing it may be unnecessary. The fact that it is the draft for a particular project, what kind of review you need, and when you need feedback may be essential. If the reader might reasonably ask “Which draft?” or “What should I check?”, preserve the identifying detail or clarify the request.

Here’s a made-up example. Assume the sender needs a colleague to review a project draft by Thursday and focus on the figures. The original might say:

“Hi, I hope you’re doing well. I’ve been working on the project draft for a while and have made several updates since the last version. I know you have a lot on, but I was wondering if you might be able to look at it when you get a chance. The figures are one area I’m not completely sure about, and it would be helpful to know whether they look right. It would be great to have your thoughts before the end of the week, if possible. Thanks so much.”

A shorter version could be:

“Hi [Name], could you review the figures in the latest [project] draft by Thursday? Please flag anything that looks incorrect or unclear. Thanks, [Your name]”

This keeps the recipient, the item to review, the focus, the deadline, and the requested response. Replace the placeholders, and include the deadline only if it is accurate. If the recipient needs a link or attachment to find the draft, add it; shortening should not make the task harder to complete.

Read the shortened version as if you were the recipient, without relying on what you already know. Check whether you can identify the purpose, the decision or action needed, the relevant context, and when or how to respond. For a decision email, state the choice plainly and include only the criteria or constraint the reader needs to choose. If two options are being compared, name both rather than referring vaguely to “the first one” or “the other option.”

Ask yourself: “Could the reader act on this without sending a clarification question?” If not, restore the missing detail—not the whole original explanation. You can also ask someone to check whether the request and deadline are clear.

Try this five-pass edit:

1. Write the email’s purpose in a short phrase, such as “request review” or “confirm a choice.”
2. Mark the sentences containing the request, essential context, decision, deadline, and next step. Keep what applies.
3. Cut repeated explanations, long opening pleasantries, and details that do not affect the reader’s understanding or action.
4. Replace long wording with direct wording, but keep names, dates, options, and constraints that prevent confusion.
5. Read the result once for meaning and once for tone. Confirm that it still sounds respectful and that the recipient knows what to do.

If a detail is uncertain, don’t silently remove or guess it. Verify it, or use a clear placeholder while drafting.
