Internal newsletter benchmarks

How does your internal newsletter compare? Key metrics from across industries, broken down by company size.

What's a good open rate for an internal newsletter?

The average internal newsletter open rate is 75–85% — far higher than the ~21% typical of external marketing email, because you're writing to colleagues, not strangers. A healthy target is 70% or above; below 60% suggests a subject line, timing, or relevance problem. For click-through rate, aim for 10–15% of recipients clicking at least one link.

A note on open rates: Apple Mail's privacy protection pre-fetches tracking pixels, which inflates opens across the industry — including in these benchmarks. Treat opens as directional and lean on click rates when reporting to leadership.

Benchmarks by company size

Engagement falls as headcount grows — smaller organisations have tighter context and less noise. Typical ranges compiled from published industry studies:

Company size Typical open rate Typical click rate Most common cadence
Under 50 employees 80–90% 12–18% Fortnightly
50–200 employees 75–85% 10–15% Weekly
201–1,000 employees 70–80% 8–13% Weekly
1,000+ employees 60–75% 6–10% Weekly or twice-weekly

What to aim for

Wherever you sit today, these are the thresholds worth managing towards:

Metric Needs work Healthy Excellent
Open rate Below 60% 70–80% Above 80%
Click-through rate Below 5% 10–15% Above 15%
Cadence kept Ad hoc Same day, most weeks Same day, every week

Why internal newsletter benchmarks matter

Internal newsletters typically achieve significantly higher engagement than external marketing emails. With a captive audience of employees, your open rates should be well above external averages — and if they're not, benchmarks tell you how big the gap is and where to look first.

Key findings

  • Companies sending weekly newsletters see 23% higher engagement than monthly senders
  • Newsletters with personalised subject lines see 12% higher open rates
  • Including team spotlights increases click-through rates by 34%
  • Mobile-optimised newsletters get 2.3x more engagement from field workers

How to close the gap

  • Low opens? Fix the subject line first — steal from our internal newsletter subject line library — then experiment with send day and time.
  • Low clicks? Your content mix is the lever. Lead with people stories, not policy. Our guide to writing internal newsletters covers the formats that get read.
  • No data at all? If you send from Outlook or Gmail you can still measure. Engagement tracking baked into exported HTML gives you opens and clicks without a sending platform — that's how our free plan works.

Benchmark questions

What is the average open rate for an internal newsletter?
Around 75–85%, with 79% a commonly cited average — roughly four times the ~21% typical of external marketing email. Remember that Apple Mail privacy protection auto-opens tracking pixels, so real attention is somewhat lower than the reported number; treat opens as directional.
What is a good click-through rate for an internal newsletter?
10–15% of recipients clicking at least one link is healthy; above 15% is exceptional. Clicks are the more trustworthy engagement signal because they can't be inflated by pixel pre-fetching — if you report one number to leadership, make it clicks.
How do internal newsletter benchmarks differ by company size?
Engagement falls as headcount grows. Teams under 50 people typically see 80–90% opens, mid-market companies (50–1,000) see 70–85%, and enterprises over 1,000 employees see 60–75%. Larger orgs offset this with segmented sends and more rigorous content curation.
How often should you send an internal newsletter?
Weekly is the most common cadence among engaged organisations, and weekly senders see roughly 23% higher engagement than monthly senders. Consistency matters more than frequency — a newsletter that lands the same day every week builds a reading habit; an ad-hoc one never does.
Are email open rates still reliable in 2026?
Only directionally. Apple Mail privacy protection pre-fetches tracking pixels and registers an open whether or not a human read anything, inflating open rates across every platform. Use opens to spot trends, and use click-through rate as your headline engagement metric.
How do I report internal newsletter engagement to leadership?
Report click-through rate as the headline number, trended over the last quarter, alongside which sections earned the clicks. That tells leadership what employees actually engage with — far more useful than a single open-rate figure. If you send from Outlook or Gmail, tracking built into the exported HTML can capture this without switching tools.

Know your own numbers

Internal Newsletter bakes open and click tracking into the HTML you export — so you get real engagement data even when you send from Outlook or Gmail.
