Common Mistakes to Avoid

  • Overloading text: Keep paragraphs short and scannable. Use headings or bullet points for readability.

  • Ignoring space alignment: Leave enough space around key sections like headers, signatures, or calls to action.

  • Mismatch with envelope type: Choose double-window for business addresses, or non-window grey envelopes for more personal or confidential communications.
