Constant Contact versus Mailchimp is the small business email question, and the generic comparisons all miss the same thing. The answer depends on who operates it and what the business actually sends. For a gym, that means trial follow-ups, retention emails, class announcements, and a monthly newsletter, run by an owner or front-desk manager in stolen minutes. Not by a marketer. Judged on that reality, the two platforms split cleanly. Here is the honest comparison, criterion by criterion, with a verdict that commits.
Figures current to July 28, 2026 and rechecked each quarter.
Part of a bigger question. This is one example of a broader topic — How To Start A Business With No Money. Start there if you want the full picture.
The philosophical difference first
The two products embody different bets. Constant Contact bets on simplicity. Fewer options. A shallower learning curve. Phone support. Features arranged for the owner-operator who wants the thing sent. Mailchimp bets on capability. Deeper automation journeys. More segmentation and testing power. Richer analytics. A denser interface that assumes some marketing fluency, with a famous free tier at the entry. Neither bet is wrong. The gym question is which bet matches the person who will actually log in on a Tuesday.
By the numbers (July 28, 2026)
Email returns an average of $36–$42 per $1 spent across industries in 2026, the highest of any digital channel against paid search at about $2 and social advertising at $2.80. Both platforms deliver against the same benchmark, so the comparison is features and support rather than results, which is why this page weighs onboarding over specs.
Ease of use and support
For the typical gym operator, this criterion dominates, and Constant Contact wins it. The editor, list tools, and automations are consistently the gentler learning curve. Live phone support matters enormously the night the January promotion will not send. Mailchimp's interface has grown dense as the product expanded, and support at lower tiers leans on documentation and chat. A gym with a marketing-savvy operator can dismiss this row. Most gyms cannot. This row is why.
Automation and the gym's actual journeys
Mailchimp wins raw automation power. Multi-step journeys with branching. Behavior triggers. Testing Constant Contact does not match. The honest gym question is whether the difference gets used. The journeys a gym needs, trial welcome series, post-visit follow-up, member milestones, re-engagement, exist comfortably on both platforms. Gyms integrating attendance data and building branching win-back logic will feel Mailchimp's ceiling advantage. Gyms running the standard journeys will never touch it.

What Is Your Email List Worth?
Most owners have no idea. Put in your numbers and find out what the list is actually worth.
Lists, segmentation, and reporting
Both platforms segment well enough for the gym reality: trials, actives, alumni, class-interest tags. Mailchimp's segmentation and predictive tools go deeper, and its reporting is genuinely richer, useful if someone reads it. Constant Contact's reporting covers opens, clicks, and growth, which is what a gym owner actually checks. On pure capability this section leans Mailchimp. On capability-that-gets-used, it is close to a tie, and honest comparisons say so.
Price, contacts, and the tier trap
Both price by contact count in ascending feature tiers. Both punish hoarded dead lists, so prune annually either way. Mailchimp's free tier makes it the cheaper start for a tiny list, with the caveat that its limits tighten and key features live upstairs. Constant Contact starts paid but keeps its essential features lower in the tier ladder. At typical gym list sizes, the costs land close enough that price should rarely decide this. Feature-tier fine print changes often enough that current pricing pages beat any review. Including this one.
The extras a gym might actually use
The surrounding features split predictably. Constant Contact bundles events, useful for workshops and challenges, plus SMS add-ons and simple social scheduling in one place. Mailchimp counters with a broader marketing suite, websites, deeper integrations, and stronger e-commerce tooling that matters more to online sellers than to a room full of squat racks. Check one integration before anything else: your gym-management software, because the platform that connects to your membership system inherits an advantage no feature list shows.

The Escape Plan
If you are ready to build your way out of the 9-to-5 on purpose, this is the one I would point you to. It gives you pick the right idea for your budget, prove people will pay, and know the exact math of when you can leave.
The verdict, committed
For most gyms: Constant Contact, because the operator is the constraint and simplicity plus phone support keeps the system actually running, which beats unused power every month of the year. Choose Mailchimp instead in three cases: a genuinely marketing-fluent operator who will use the deeper automation and testing, a tiny list that wants the free tier while it grows, or a gym whose management software integrates meaningfully better with it. Either platform, run consistently, patches the trial and retention leaks that actually move gym revenue. The winner is whichever one your Tuesday self will still be logged into in March.

What people ask me
Which is better for a gym, Constant Contact or Mailchimp?
For most gyms, Constant Contact: gentler learning curve and phone support keep the system running under a non-marketer operator, which beats unused power.
When should a gym pick Mailchimp instead?
Three cases: a marketing-fluent operator who will use deeper automation and testing, a tiny list starting on the free tier, or better integration with your gym-management software.
Do both handle a gym's core email journeys?
Yes: trial welcome series, post-visit follow-up, milestones, and re-engagement exist comfortably on both. Mailchimp's branching ceiling matters only with attendance-data integrations.
How do the prices compare for a gym?
Both bill by contact count in feature tiers and land close at gym list sizes. Mailchimp starts free with tightening limits; Constant Contact starts paid with essentials lower in the ladder. Check current pages.
What single factor should decide it?
The operator, then the integration: whichever platform your actual Tuesday operator will still be logged into in March, and whichever connects to your membership system.
