Emails & Communication

Quick Wins

Subject Lines

Front-load keywords. Use prefixes like [Action Required] or [FYI] so users know the priority immediately

Plain Language

Aim for a Grade 8 reading level. Use short sentences and common words. Explain acronyms on first use

Real Lists

Use the built-in Bullet or Number list buttons. Do not type manual hyphens, which screen readers may ignore

Headings

Use text styles (Heading 1, Heading 2) or bold + large font sizes to visually and structurally chunk content

Descriptive Links

Avoid "Click Here." The link text should describe the destination (e.g., "Review Q3 Report")

Contrast

Ensure text is dark enough against the background. Avoid using light gray text or color alone to convey meaning

Authoring Guidelines

WRITING

Plain Language

  • Keep it Simple: Write for your audience, not the archives. Avoid jargon.
  • Active Voice: “We approved the plan” (Active) is better than “The plan was approved” (Passive).
  • Acronyms: Always spell it out first: “Export Development Canada (EDC).” 

OUTLOOK

Structure & Formatting

  • Headings: Break large blocks of text into sections.
  • Short Paragraphs: Keep paragraphs under 5 lines to reduce visual fatigue.
  • Color: Never say “Action items are in red.” Use bolding or the word “Action:” instead. 

Links

Descriptive Links: Users scanning visually or via screen reader need to know where a link goes without reading context.

Avoid: Read the report here.

Better: Read the Q3 Financial Report.
