Email is — by far — the most-used internal communication channel at companies of all sizes, with over 90% of communicators relying on it to share important news.
Why it matters: The way you write your subject lines will decide how quickly colleagues read your update and how easy a recurring communication is to resurface. We’ve tested internal and external emails alike to nail down what works.
Two top qualities emerged:
1. Searchable: For recurring internal comms — like a newsletter or all-staff update — standardize a short phrase to include at the start of each subject line.
💡 Do you lead a team? This can also streamline new-hire onboarding. Find and forward recent all-staff updates to share progress, context and help employees get up to speed and aligned on business goals.
2. Scannable: Just like a strong headline, your subject line should tell readers something specific and valuable. Summarize 2–3 of the biggest items in your update and separate them with a comma or em dash so ideas stand out at a glance.
Be smart: These audience-first tactics work best for recurring updates, but they apply to the subject lines for all sorts of updates.
The bottom line: If you flub the subject line, nothing else you write will matter, so don’t squander their potential. Use them as another way to save your team time and get them smarter, faster.
