Every year somebody predicts the death of email, and every year the data shows otherwise. In PoliteMail’s 2026 research with internal communicators, 79% named internal email their most effective channel. Company and team meetings came in a distant second at 49%, with direct manager conversations at 45%.
The reasons aren’t mysterious. Email reaches everyone with an inbox. No algorithm decides whether your message gets seen. And when something matters, email is the record. One honest caveat: That 79% reflects what communicators say works, and email works best as the broadcast layer. Managers still do the heavy lifting on interpretation and trust. But when a message has to reach everyone? It goes to email.
Which makes the next number sting a little. PoliteMail’s report, built on two billion internal emails sent to nearly 11 million employees, found the average employee gets 14 corporate emails a month and spends a grand total of 33 minutes reading them. Thirty-three minutes. That’s all the time you’re working with. And with open rates averaging 66%, a third of your workforce never makes it past the subject line.
Do email open rates matter for internal communications?
The open rate gets all the attention, but it’s the least informative number in the report. Security scans open emails. So do stale distribution lists and people clearing their inbox on autopilot. An open confirms delivery, nothing more. What employees do next is the real story, and there the news is good: 83.7% of employees who open an internal email spend real time with it. People aren’t ignoring you. They’re choosing carefully.
Links, on the other hand, are mostly wasted effort. Only 7% of recipients click one. If something matters, it belongs in the body of the message, and if you truly need the click, put the button at the top where the preview pane can do some of the work.
The same goes for length. Employees handle frequent, focused messages far better than the occasional everything-email, and plenty of readers will only ever skim. So write for the skimmers. Headers, bullets, a little bold. That’s not dumbing it down. That’s respecting their time.
Key takeaways on email for internal communications teams
Report on attention, not just opens.
Put attention metrics on your dashboard and treat open rates as the top of the funnel. Attention metrics mean read time vs. skim vs. ignore. The leadership conversation changes when you can show who read, not just who opened.
Audit your open rate for false positives.
Security scans, outdated lists and passive opens all pad the number. Clean measurement comes before honest benchmarking.
Front-load everything.
Your most important content, and any link you need clicked, goes at the top where it’s front and center in the preview pane.
Write for the skimmer.
If someone gives you 30 seconds, they should still leave with the point. When the headers alone tell the story, you’ve done it right.
Rethink cadence.
Frequent, focused messages beat infrequent, exhaustive ones. The long quarterly internal newsletter is a habit worth reconsidering.
Pair the broadcast with the human touchpoint.
Email carries the message, while managers carry the meaning. Build reinforcement into the plan instead of assuming the send did the job.
Email didn’t end up at the top of the channel rankings by accident. Keeping it there means making the most of the 33 minutes employees give it.
