The internal newsletter is the most common internal comms channel in UK organisations — and the most frequently ignored. Gallagher's State of the Sector research shows average open rates for internal newsletters sit around 35-45% across UK companies. The difference between a newsletter people read and one they archive unread comes down to structure, not writing quality.
The Format That Works: 90 Seconds or Less
Your newsletter should take no more than 90 seconds to read. That is approximately 350-400 words. Every word beyond that threshold costs you readers.
The Template
1. Lead Story (3 sentences, 60-80 words) The single most important update. This is the one thing you would tell someone in a lift. Write the headline as if it were a news story, not a corporate update.
Good: "UK operations team hits 99.2% delivery rate — highest in company history" Bad: "Update on our ongoing commitment to operational excellence"
2. Secondary Items (2-3 items, 1 sentence each with a link) Brief summaries with a "read more" link to the intranet or SharePoint for those who want detail. Do not try to explain everything in the newsletter — it is a signpost, not a destination.
Examples:
- "New hybrid working policy takes effect 1 March — read the full guidelines here [link]"
- "Q4 results published: revenue up 14%, details in the investor section [link]"
- "FCA Consumer Duty training deadline extended to 30 April — book your session here [link]"
3. People Spotlight (50-80 words) One person or team. Name them, say what they did, say why it matters. Rotate across departments, locations, and seniority levels.
"The Manchester customer service team resolved 340 complaints in January — 22% above target — while maintaining an NPS score of 74. Special mention to Priya Sharma, who handled the Aviva account migration single-handedly when the lead was on leave."
4. One Action Item Every newsletter should have exactly one thing the reader needs to do. Not three, not "several opportunities" — one. Put it at the bottom with a deadline and a link.
"Complete your annual compliance training by 15 March. Takes 20 minutes. Start here: [link]"
What Not to Include
- CEO quotes in every issue (save these for the monthly CEO update)
- More than 5 items total (forces readers to decide what matters, so they read nothing)
- Corporate jargon: "leveraging synergies," "driving transformation," "best-in-class solutions"
- Anything without a clear "so what" for the reader
Sending Schedule
Frequency: Weekly
Send at the same time every week. Tuesday or Wednesday between 9:00-10:00am performs best in most UK organisations based on Poppulo and Staffbase analytics data. Avoid Monday (inbox overload) and Friday (mentally checked out).
Consistency Over Perfection
If you do not have a strong lead story one week, run with a shorter newsletter. Do not skip the send. The habit of looking for it on Wednesday morning is more valuable than any single edition.
Common Mistake: The Fortnightly Newsletter That Became Monthly
A UK professional services firm with 3,000 employees started with a fortnightly newsletter averaging 42% open rates. During a quiet period, they skipped two editions. Then they decided to go monthly. Open rates dropped to 22% within three months and never recovered. Employees lost the habit. When they reverted to weekly, it took six months to rebuild to 38%.
Design Principles
Mobile First
Poppulo data shows 45-55% of internal newsletter opens happen on mobile devices across UK organisations. Design accordingly:
- Single column layout
- Minimum 14px body text
- Buttons, not text links (easier to tap)
- No images wider than 600px
- Subject line under 40 characters (mobile truncates at 40-45)
Consistent Branding
Use the same template every time. The same header, the same section order, the same footer. Employees should recognise the newsletter from the subject line and first visual element without reading a word.
Subject Line
Use a consistent prefix followed by the lead story:
"[Weekly Update] UK delivery rate hits record 99.2%"
The prefix acts as a filter label. The lead story acts as the hook. Together, they tell the reader: this is your regular update, and here is why this week matters.
Measuring Performance
Key Metrics
| Metric | Target | Tool | |---|---|---| | Open rate | 40%+ | Poppulo, Staffbase, Mailchimp (if no dedicated internal tool) | | Click-through rate | 10-15% | Same as above | | Read time | Under 90 seconds | Poppulo provides this; others estimate from click timing | | Unsubscribe/opt-out rate | Under 1% per month | Same as above |
What the Metrics Tell You
- Open rate declining: Your subject lines are not working, or the newsletter is too frequent/infrequent for your audience. Test different subject line formats for 4 weeks.
- Open rate stable but CTR declining: People are opening but not finding value. Review whether the links lead to genuinely useful content.
- Read time increasing beyond 90 seconds: The newsletter is too long. Cut a section.
- Consistent 40%+ open rate: You have built a habit. Protect it by maintaining the schedule and format.
Segmentation
If your organisation has distinct populations (office vs. field, UK vs. international, corporate vs. operational), consider segmented versions:
- Keep the lead story and secondary items the same across all versions (shared identity)
- Swap the people spotlight and action item to be relevant to each segment
- Track open rates by segment to identify if one group is under-served
Poppulo and Staffbase both support audience segmentation natively. For simpler setups, maintain two Mailchimp audiences or two distribution lists.
Editorial Planning
Maintain a 4-week forward plan:
| Week | Lead Story | Secondary Items | Spotlight | Action | |---|---|---|---|---| | Week 1 | Q4 results summary | Policy update, training deadline | Finance team | Complete compliance training | | Week 2 | New product launch | Regional office news, charity event | Manchester warehouse team | Register for town hall | | Week 3 | CEO video on strategy | Benefits enrollment, IT migration update | Customer service individual | Submit peer nominations | | Week 4 | Industry award win | Regulatory update, sustainability report | Engineering project team | Complete annual survey |
Plan the lead story at least 2 weeks ahead. The secondary items and spotlight can be finalised 3-4 days before send. This prevents the Wednesday morning scramble that produces weak newsletters.
Who Writes It
One person writes and sends the newsletter every week. Not a rotating committee — one person who owns the quality, voice, and schedule. This is typically a mid-level internal comms specialist or the IC lead. They gather content from business units via a simple intake form (Google Form or Microsoft Form with a Thursday deadline for the following week's edition) and make editorial decisions about what gets included.
The newsletter owner has the authority to reject submissions that are too long, too corporate, or irrelevant to employees. Without that authority, the newsletter becomes a dumping ground for every department's announcements, and readership collapses.
