How to write a gym newsletter that your members actually open (read and click)

Ever feel like you’re shouting in the void?

You post an update on Instagram… Response? [Crickets chirping].

Then you emailed your members. Got 20% open rate, 2% clicks, and nobody showed up to the challenge you hyped for two weeks.

For gym owners, communication isn’t just about announcements; it’s how you build connection, increase member retention, and drive in-studio engagement. But relying solely on social media? That’s like training only arms and expecting a full-body transformation.

That’s where the humble but mighty fitness newsletter brings the results (only when done right).

That being said. It becomes your gym’s most powerful retention tool.  And when done wrong, it becomes another “mark as read” in your member’s inbox. None of us wants that kind of response, so here you’ll learn to do it the right way. 

Let’s talk without bombarding you with big marketing stats, so you won’t feel left behind. Not spitting stats, but facts and secrets that drive you results. 

But why do so many gym newsletters feel broken?

Most fitness newsletters are overlooked because they feel built to inform, not engage. The subject line doesn’t connect, and the content just lacks personality. The layout feels like a 2005 chain email. There’s no spark in the message; it lacks aim, leaving readers feeling “So what do I do?”.

Here’s what you need to avoid:

• Repeating the obvious (like weekly class schedules already listed in your app).
• Being too salesy (Buy this! In every other paragraph).
• Poor design and formatting (walls of text, no hierarchy, hard-to-scan info).
• Sending the same email to all members regardless of their interests.

The only fix needed is to shift the purpose.

Remember, your newsletter isn’t just an update; it’s a conversation, a trust-builder, and a habit-forming touchpoint that keeps members emotionally tied to your gym. 

Members secretly want this from your fitness newsletter

Your members are busy. They scroll fast and click even faster. So when they do open your email, it has to feel tailored, valuable, and community-first. 

So here’s what gets reading and returning:

• “What’s in it for me?” content: New classes, changes, or updates that affect their routine.
• Insider access: Trainer Q&As, behind-the-scenes sneak peeks, early-bird signups.
• Member spotlights: Recognize their progress or milestones, make them feel seen.
• Digestible fitness tips: Nutrition hacks, quick routines, and mobility drills they can do today.
• Social motivation: Upcoming events, gym challenges, or referral incentives.

If you’re unsure of what kind of content sparks engagement, this email marketing guide for gyms offers smart insights into content selection and frequency strategies.

The game plan: creating newsletters that perform like a 1-rep max

Before hitting “send”, you need a process. A consistent, clear, and scalable one. Here’s a proven roadmap to structure your fitness newsletter for success.

Step 1: Know why you’re sending it (Define the objective)

Your newsletter should always serve one (and only one) of these goals:

• Keep members informed.
• Drive attendance to classes or events.
• Boost engagement outside the gym.
• Increase referrals or member upgrades.

Start here. Without a clear purpose, your newsletter becomes noise. With one, it becomes influence.

Step 2: Plan content that aligns with your gym’s voice

Be intentional with your voice and the words you choose. Structure beats spontaneously. Create a monthly or bi-weekly calendar. Consider rotating core segments:

• Coach’s corner: Tips from trainers on recovery, training mindset, or client success stories.
• Upcoming events: Clear visuals and links to RSVP.
• Member shoutouts: Celebrating progress with authenticity.
• Pro tips: From foam rolling routines to supplement breakdowns.

The key is consistency. Members should expect certain sections and look forward to them.

Step 3: Nail the subject line

Your subject line is your first impression and possibly your last. It decides the destiny of your message. Take it seriously and make that first impression count. Instead of “August Newsletter”, highlight the benefit and value they’ll get from reading you.

 Try addressing this way:

• This challenge broke records (you’re next).
• What 83% of members missed last week.
• Your August sweat schedule (Sneak peek inside).

Great subject lines use curiosity, urgency or exclusivity to get clicks.

Want your open rates to climb? A/B test your subject lines. Many gym marketing platforms, like Wellyx, make this super easy without the need for extra tools.

Step 4: Structure it like a community-driven story

Think of your newsletter as a mini-magazine that feels like your gym.

Header – A quick welcome or personal note from a coach or manager.

Main story – Highlight 1-2 important things (event, launch, change).

Spotlight – Member transformation or trainer moment.

Quick win – A mini tip, 60-second stretch, playlist link, etc.

Call to action – what you want them to do (book, share, register).

Don’t overcrowd it. Just keep your message clean, bold, and offer simple wins.

Step 5: Send the right message to the right people

Segment your audience. This one’s non-negotiable.

• Active members: class updates, new trainers, community events.
• Leads or trials: Motivational success stories, new joiner incentives.
• PT client: Personal training tips, performance progress, nutrition.
• Dormant members: Friendly nudges, “we miss you”, re-engagement challenges.

Generic blasts hurt engagement and increase unsubscribes.

If segmentation sounds like a tech headache, Wellyx gym marketing software handles it with ease. You can filter your member base, automate email flows, and send the right content to the right person, every time.

Step 6: Design for skimmers (Because everyone’s a skimmer)

Note that 70%+ of your members will read your email on their phone. Your email template should fit the mobile screen without compromising the quality. So design your fitness newsletters accordingly:

• Use headers, dividers, and spacing.
• Keep paragraphs 2-3 lines max.
• Add 1-2 high-quality images (avoid heavy graphics).
• Include clear, tappable CTA buttons.

Step 7: Track results like you track your PRs

You don’t send emails just for the sake of sending them, something at least. When you have a clear goal in mind, you want results too. And measuring those results should be properly guided. 

Use your email platform’s analytics dashboard to check what’s working. Do more of what gets clicks, and cut what gets skipped. Over time, your newsletter becomes a finely tuned marketing machine.

Final word: Newsletters aren’t dead, bad ones are

A well-built fitness newsletter is your gym’s version of personal training for communication. It builds habits, strengthens relationships, and nudges your members toward the next goal, without them even realizing it.

But to make it work, you need the right mindset, message, and method:

• Use real content that reflects your gym’s community.
• Segment your audience so they get what they care about.
• Track results so your newsletter improves month after month.

And if you’re tired of sending email newsletters, SMS, and managing bookings across five platforms, consolidate. Wellyx gym marketing software makes it easy to send beautifully branded, personalized newsletters that connect with your members at the right time, with no guesswork or messy integrations.

Because a real connection isn’t built on algorithms, it’s built on trust.
