Email Marketing for Gyms and Fitness Studios: Tools and Tactics

A gym loses most of its new members within the first 90 days, and almost none of them announce they are leaving. They just stop showing up. Attendance drops from four visits a week to one, then to zero, and the cancellation arrives a month later as a formality. By the time you notice, the relationship is already over. Email is the cheapest tool you have for catching that drift early — a class reminder, a check-in after a missed week, a nudge toward a personal training session — and most fitness businesses use it for almost nothing beyond the occasional holiday-hours announcement.

This guide covers the email marketing tools worth considering for gyms, boutique studios, and independent trainers. Each one has been judged on the things that matter for a membership business: automation that can react to attendance and signup dates, SMS for time-sensitive class reminders, pricing that stays sane as your member list grows, and an editor a busy studio owner can actually use between sessions. Every tool here has a real weakness, and I have named it.

MailerLite

MailerLite is the starting point for most independent studios and solo trainers. The free plan covers 250 subscribers and 2,500 emails per month — tight, but enough to test a retention program for a single-location studio before paying anything. The paid Comfort plan starts at $12/month — less than many gyms spend on a single boosted social post.

The automation builder is the part that matters for fitness. You can build a welcome series that goes out when someone joins, a date-based sequence tied to a membership start date, and a re-engagement flow that triggers when a subscriber has not opened in 60 or 90 days. For a studio, that last one is the closest thing to an early-warning system for churn you can set up without custom software. The editor is clean enough that a studio owner can put together a “new spring schedule” email in fifteen minutes.

Where MailerLite struggles: The free plan has been cut twice — from 1,000 to 500 subscribers in September 2025, then to 250 subscribers in MailerLite’s June 2026 plan restructuring — so an established gym with a few thousand members lands on a paid plan immediately. It has no built-in SMS, which is a real gap for class reminders — you would need a separate tool for texts. Advanced segmentation sits on the higher Power plan, which starts at $25/month at 500 subscribers. Check MailerLite’s pricing page for current rates before committing.

Brevo

Brevo (formerly Sendinblue) is the tool to look at if class reminders and last-minute texts are central to how your gym communicates. It runs email and SMS from the same campaign builder and the same contact list, so a “two spots left in tonight’s 6pm class” message can go out as a text without exporting anyone to a second platform.

Brevo’s pricing model fits fitness businesses unusually well. Instead of charging by contact count, it charges by emails sent per month. A gym that stores 5,000 members but only emails the whole list once or twice a week pays far less here than on a contact-based tool. The free plan stores unlimited contacts and allows 300 emails per day; paid plans start around $9/month and remove the daily cap. SMS is billed separately as credits, which keeps your email costs predictable while still giving you texts when a class fills up.

Where Brevo struggles: The interface is busier than MailerLite’s, and the template editor is functional rather than polished. Brevo grew up serving developers and marketers, and the onboarding still reflects that — handing it to a part-time front-desk person will take more training than a friendlier tool would. SMS credits are also priced per country, so a high volume of reminder texts adds up; price it against your reminder volume before you commit.

Here is how the two budget front-runners stack up directly:

ActiveCampaign

ActiveCampaign is the pick for gyms that treat email as a retention engine rather than a newsletter. Its automation goes deeper than anything else on this list, which matters once you start mapping the full member lifecycle: trial, onboarding, first-90-days check-ins, renewal warnings, and win-back.

The value shows up in conditional logic. You can build a flow that watches whether a new member has booked their first class, branches based on the answer, and sends a different message to the member who is engaged versus the one who has gone quiet. Paired with the built-in CRM, a studio can also track leads from a free-trial form through to a signed membership, which is closer to what a sales-driven gym actually needs than a plain broadcast tool.

Where ActiveCampaign struggles: It is the most expensive option here for what most studios need, and it has no free plan — only a 14-day trial. Pricing starts around $19/month for 1,000 contacts on monthly billing, and the genuinely useful automation features push you toward higher tiers fast. The learning curve is steep; the power that makes it worth the price is also what makes it slow to set up. A solo trainer with 300 clients will overpay for capability they will not use. See the ActiveCampaign pricing page for current numbers.

Omnisend

Omnisend earns its place if your gym sells anything online — supplements, apparel, branded gear, or paid digital programs. It is built for ecommerce, with email and SMS combined and templates designed around product promotion and cart recovery.

For a studio running an online store alongside memberships, the abandoned-cart and post-purchase flows are the draw. Someone who adds a protein subscription and does not check out gets an automatic reminder; someone who buys gets a follow-up. The free plan covers 250 contacts and 500 emails per month, which is enough to test the automation before paying. Paid plans start around $16/month.

Where Omnisend struggles: If you do not sell anything online, most of what you are paying for goes unused — the ecommerce focus is the whole point, and a pure membership gym with no store will get more value from a general tool. Billing is based on “billable contacts,” which can include non-subscribed contacts, so the count you pay for may be larger than the list you actually email. Check the Omnisend pricing page before assuming the entry price applies to your list size.

Mailchimp

Mailchimp is the tool most gym owners have already heard of, and familiarity has real value when you eventually hand the work to a part-time marketer. The template library is large and the drag-and-drop editor is forgiving for someone sending their first campaign.

For a fitness business, the appeal is mostly the low barrier to a good-looking email. Save your brand colors and logo once, and a weekly class schedule or a new-program announcement comes together quickly. The Customer Journey builder handles simple automations like a welcome email or a birthday offer.

Where Mailchimp struggles: Beyond the reduced free tier, pricing scales sharply with contact count — paid plans start around $13/month on Essentials but climb quickly as your member list grows, and multi-step automations are gated behind the Standard tier. The single-step automation on lower plans cannot handle the branching retention flows a membership business benefits from. Confirm current rates on the Mailchimp pricing page.

How to Choose

Start with how you communicate, not with the feature list. If most of your urgent messages are class reminders and schedule changes, a tool with native SMS — Brevo or Omnisend — saves you from stitching two platforms together. If your bigger problem is members quietly drifting away, prioritize automation depth, which points toward ActiveCampaign or MailerLite’s date-based flows.

Then check the price at your real list size, not the headline entry price. A gym with 4,000 members pays very differently across these tools: a contact-based tool charges for every member you store, while Brevo’s send-based model charges for activity. Run your actual member count through each pricing calculator before deciding, because the cheapest tool on a 500-contact plan is rarely the cheapest at 4,000.

Finally, be honest about who will run it. The most capable tool is worthless if it sits unused because the front desk finds it confusing. A solo trainer is almost always better served by MailerLite’s simplicity than by ActiveCampaign’s depth, even though the latter can technically do more. For more options across budgets, see our roundup of the best email marketing tools for small business, and if you want to dig into a single tool, the full MailerLite review covers its automation in detail.

For the majority of single-location studios and independent trainers, MailerLite is the right starting point: low cost, automation that covers retention, and an editor anyone can use. Gyms that lean heavily on text reminders should look at Brevo’s pricing instead, and growing operations that need true lifecycle automation will get the most from ActiveCampaign — provided someone has the time to build it out. Whichever you pick, the win is the same: catch the members who are drifting before the cancellation email arrives.
