How Long Should Business Emails Be?

Emails are not meant to be manifestos!

The Short Answer…

As long as you need to communicate clearly and succinctly. For most, this is only a couple of paragraphs.

The Longer Answer…

Here are 5 key reasons why business emails should not be too long:

  • Respects the recipient’s time: Busy professionals receive dozens (or hundreds) of emails daily. A concise message shows consideration and increases the likelihood they’ll read it promptly rather than skim or skip it.
  • Improves clarity and focus: Shorter emails force you to prioritize the most important points, reducing confusion and making your core request or information easier to understand and remember.
  • Boosts response rates: People are far more likely to reply quickly to a brief, scannable email than one that requires significant time and effort to digest.
  • Reduces the risk of key details being missed: Long emails often bury critical information, leading to overlooked action items, misunderstandings, or follow-up questions that could have been avoided.
  • Enhances professionalism and efficiency: Concise communication signals strong writing skills and respect for collaborative workflows, helping build trust and maintain momentum in business relationships.

Often, picking up the phone and discussing the issues at hand is much more efficient and effective than typing endless commentary that may not get to the heart of the topic or create more questions than provide answers.

It is rare to find a talented communicator who can hold a reader’s attention and write effective long emails. Email is communicating with the written word, after all! This is a skill I work on daily (and I hope you are too).

Often, long emails do not hold readers’ attention, leading them to scan for the details or answers they seek. And by doing so, they may possibly miss essential information.

I have even caught myself doing this when pressed for time, and I find a long email with huge paragraphs in my inbox. This is where brevity and white space are your friends!

Email Composition Tips

Here are some quick tips to keep in mind for those, the majority, that scan:

  • A handful of paragraphs at most.
  • 2-3 sentences per paragraph.
  • No more than 15 words per sentence.
  • Use bulleted lists for brief points.

Keeping your replies to the point is where down-editing comes into play. Removing what doesn’t apply and commenting only on what does minimizes confusion and keeps the email focused.

Use bullet points to convey your thoughts in a short, sweet, and concise manner. Don’t worry about having to know code to create bulleted points; do what I do—use “=>” before each point. Then, hit enter twice after each topic to space things out and provide some white space.

Concise and To-The-Point

The key is to think about what you want to accomplish with your email and stay on target. In most cases, if your email exceeds a handful of paragraphs, it may be best to consider another alternative.

For example, when a client needs a lot of information from me, I’ll include links to the areas of my site that cover the info they’re seeking rather than repeating it in an email. Or I’ll create a PDF and send a short, to-the-point email noting what the attached document contains.

A recent study found that email can decrease productivity by up to 40%. Keeping your emails short, brief, and concise helps both sides be more efficient and spend less time emailing.
