8 Best SMS Marketing Software for Gyms in 2026: Tools Compared

SimpleTexting fits a gym because the daily work is conversation, not broadcasting. Class reminders go out on a schedule, members reply to ask about a full class or a waitlist spot, and three staff seats share one inbox so the front desk and the trainers see the same thread. Polls and text-to-win campaigns fill quiet classes, and unlimited contacts mean the member list never costs extra.

The catch is the credit math. The entry plan is $29 a month for 500 credits with a toll-free number, or $39 with a local number, and MMS costs three credits. A gym that texts every member three times a week will outgrow 500 credits fast, so price the plan at your real weekly volume.

Textedly suits a gym that wants the full toolkit without a feature ladder. Every plan includes every feature, so drip reminders, two-way chats, text-to-pay for memberships and review requests all work from Basic at $29 a month for 500 messages. Incoming messages are free, and the account comes with a toll-free number and a 10DLC number.

The catch is the surcharge. An $8 monthly telecom surcharge applies to paid plans, so Basic costs $37 a month in practice. There is no free plan, only a trial with 50 messages, and extra teammates cost $10 a month each, which adds up for a gym with several trainers.

EZ Texting is the cheapest way for a gym to start texting members. Launch is $25 a month, or $20 billed annually, for 500 credits, and setup takes minutes: import the member list, set a keyword for class signups and send a first reminder. Two-way messaging and MMS work from the entry plan, and the interface is simple enough for front-desk staff.

The catch is the seat limit. Each plan includes only one user, extra seats cost $10 a month each, and Launch carries a $5 monthly telecom fee. Team texting only arrives on Scale at $125 a month, so a gym where several trainers answer members pays more than the sticker price.

SlickText fits a gym that sends the same reminders every week. Drip campaigns handle the class reminder, the day-before nudge and the follow-up after a missed class, and every plan includes all features, unlimited users and unlimited contacts. Plans start at $29 a month for 500 credits, with two months free on annual billing.

The catch is the compliance-first design. Opt-in tools are strict, which is good for deliverability but adds a step before a new member can be texted. Rich messaging carries setup and annual fees, and the most useful automation sits above the entry tier, so the $29 plan is thinner than it looks.

Klaviyo suits a gym that already runs email and wants text on the same member record. Email, SMS, WhatsApp and push all run against one profile, so a welcome flow can email a new member, then text them a class reminder if they do not open it. The free plan covers 250 profiles, 500 emails and $5 of mobile messages a month.

The catch is the price curve. SMS is billed per message at about $0.01 per US toll-free text plus carrier fees, on top of the email plan that starts at $20 a month. A gym with a large member list will see the bill climb with profile count, and the SMS inbox is thinner than a dedicated texting tool.

Omnisend is the best free starting point for a gym that wants to test texting before paying. The free plan covers 250 contacts and 500 emails a month with automation included, and the same account handles email, SMS and push once you upgrade. Pre-built welcome and win-back flows switch on fast, which suits a gym chasing lapsed members.

The catch is that SMS is a paid-tier channel. New subscribers cannot buy SMS on the Standard plan at $16 a month; SMS needs Pro at $59 a month, with rates from $0.007 per message. The free plan also caps SMS at 60 credits, so it is a trial of the channel, not a working reminder system.

Sakari fits a gym that already runs a CRM and wants texts tied to member records. Native links to HubSpot, Salesforce, Pipedrive and ActiveCampaign let reminders fire from the member record, and the shared inbox handles replies with assignment across the team. Every plan includes unlimited users and contacts, one free number, and credits that roll over for 90 days.

The catch is the per-message rate. Sakari starts at $25 a month, but US segments run about $0.0304 each on the entry plan, which is three to four times the per-message rate of the volume tools. A gym that texts every member several times a week will feel that rate fast.

Attentive is the pick for a gym chain, not a single location. Its AI tools draft replies, tune send times and run conversational journeys that answer common questions such as class times and membership holds before a human steps in. White-glove onboarding sets the program up for you, and the platform is built for high message volume.

The catch is the price and the process. Attentive publishes no pricing, so every deal is a negotiated quote that usually starts with an annual commitment and a quarterly minimum. A single gym will not reach the volume where that deal makes sense, and the tool is built for ecommerce rather than fitness.
