Most coaches know they should send email. Fewer know what “good” looks like anymore.

That matters because email is still one of the few channels you fully own. No algorithm. No rented audience. But if you judge performance with bad benchmarks, you can think your funnel is healthy when it is quietly underperforming.

Here is the simple version: opens still matter a bit, clicks matter more, and list quality matters more than both. The 2026 benchmark picture is clearer than most coaching newsletters make it sound.

The baseline numbers coaches should know

The best current benchmark set comes from MailerLite’s 2025 benchmark report, which analyzed 3.6 million campaigns sent from 181,000 approved accounts across December 2024 to November 2025.

In that dataset, the coaching category posted a 48.07% open rate and a 1.42% click rate. Across all industries, the median was 43.46% open rate, 2.09% click rate, and 0.22% unsubscribe rate.

That gives solo coaches a useful reality check:

The interesting part is this: coaches in MailerLite’s dataset opened at a higher rate than the all-industry average, but clicked at a lower rate. That usually means one of two things. Either the audience trusts the sender but the email body is too generic, or the call to action is buried under “value” content that never creates movement.

Why open rates can fool coaches in 2026

This is where a lot of coaching businesses misread the scoreboard.

According to Omeda’s analysis of Apple Mail Privacy Protection, based on about 80,000 deployments and roughly 2 billion emails sent before and after Apple’s privacy rollout, total open rates jumped from 22.6% to 40.5% after six months. Unique open rates also rose from 15.2% to 29.0%.

That was not because email marketers suddenly became brilliant. It happened because Apple started preloading email content in a way that inflates opens.

So if you are a coach looking at a 50% open rate and feeling good, slow down. That number may reflect trust. It may also reflect Apple’s measurement distortion.

What should you track instead?

  1. Click rate. Did someone take an action?
  2. Reply rate. Did the email start a real conversation?
  3. Booked calls or purchases from email. Did the sequence produce revenue?
  4. Unsubscribe rate by sequence. Which emails repel the right people, and which repel everyone?

Open rate is still useful as a directional signal. It just should not be your main KPI.

Why email client behavior changes how coaches should write

The inbox environment itself also matters more than most coaches realize.

Litmus’ February 2026 Email Client Market Share report, calculated from over 1.1 billion opens, says Apple Mail and Gmail together account for nearly 90% of total market share.

That has two practical implications for coaches.

First, your emails need to be easy to scan on mobile. A huge chunk of your audience is opening inside Apple Mail or Gmail on phones, not sitting at a desktop reading your carefully crafted manifesto.

Second, fancy formatting is usually a downgrade. If your newsletter depends on image-heavy layouts, multi-column sections, or too many buttons, you increase the odds that the email looks messy, loads poorly, or hides the actual CTA.

For most coaching businesses, plain-text style or lightly formatted emails win because they feel personal, render well, and push attention toward one next step.

What a healthy coaching email funnel probably looks like

Based on the benchmark data above, a healthy solo coach email program in 2026 probably looks more like this:

If you are below those levels, do not jump straight to “I need better email software.” Most coaches do not have a tooling problem. They have one of these four problems:

  1. Weak list intent. Too many freebie signups who never wanted coaching.
  2. Boring CTA structure. Useful content, no concrete next step.
  3. Inconsistent sending. The audience forgets who you are.
  4. One-message-for-everyone writing. New leads, warm prospects, active clients, and past buyers all get the same email.

Segmentation fixes more than most people think. Even simple splits like leads vs clients, or business coaching vs health coaching, can improve relevance fast.

The smartest move for coaches right now

Do not chase inflated opens. Tighten your email system.

A better approach is this:

That is how email starts acting like a sales system instead of a content habit.
