Which of the following is a best practice for email attachments and message hygiene?

• A. Attach as many files as possible to show thoroughness.
• B. Include only necessary attachments and keep messages concise.
• C. Use allcaps in subject lines.
• D. Ignore formatting.

Answer: (B)

Keep attachments lean and messages clear. The best practice is to include only what’s truly necessary and to keep the overall message concise. This helps prevent unnecessary clutter for the recipient, reduces the chance of sending or receiving oversized files, and lowers security risks from unneeded attachments. It also makes the email easier to read, faster to open, and more likely to be acted on. When you do need to share larger or multiple files, consider compressing them or providing a secure link to a cloud location instead of packing everything into the email itself. Pair that with a straightforward subject line and a brief, purpose-driven message so the recipient knows exactly why you’re emailing and what to do next.

Attaching many files can create clutter, slow delivery, and raise security concerns. Using all caps in subject lines comes across as shouting and hurts readability, and ignoring formatting leads to hard-to-read messages that can cause miscommunication.
