The Quick Answer
Choose Mailchimp if you are an independent fitness professional needing basic client updates, promoting a free trial class, or sharing simple session booking links, especially if you need a free starting point. Choose ConvertKit if you are a fitness coach building an audience with automated client onboarding sequences, selling online workout programs, or offering paid digital guides. Choose Beehiiv if you plan to build a large fitness newsletter, monetize through sponsored content, or offer a premium subscription to exclusive routines.
Side-by-Side Breakdown
Mailchimp: free for up to 500 potential clients; then around $13-350/month. Good for sending class schedules or discount offers. Automation for follow-ups after a discovery call is basic and limited on free plans. ConvertKit: free for up to 1,000 subscribers (think potential clients or workshop attendees); then around $25-599/month. Strong for segmenting clients by interest (e.g., 'yoga clients,' 'HIIT clients') and automating onboarding sequences for new personal training clients or selling a digital meal plan. Beehiiv: free for up to 2,500 subscribers (for your health & fitness tips newsletter); then $39-99/month. Designed for trainers who want to grow a large audience with a consistent fitness newsletter, perhaps monetizing through brand sponsorships or a paid subscription for advanced routines. Includes tools to get more subscribers.
When to Choose Mailchimp
You are a solo personal trainer, yoga instructor, or Pilates teacher just starting out, maybe with 10-20 regular clients, and need basic email communication. You primarily send simple emails like 'New Class Schedule,' 'Summer Bootcamp Promotion,' or 'Reminder: Your session is tomorrow.' You use it to send a monthly client newsletter with general fitness tips, not highly personalized content. You need to integrate with a simple booking system like Acuity Scheduling or Calendly for session confirmations, but don't need deep automation. You mostly send one-off emails to your full client list, without needing to tag clients by their specific fitness goals or program progress.
When to Choose ConvertKit
You're a personal trainer or fitness coach selling online programs, challenge guides (e.g., '30-Day Core Challenge'), or virtual workshops. You need to tag clients based on their interests (e.g., 'weight loss client,' 'strength training,' 'pre-natal yoga') to send targeted tips and offers. You want to create automated email sequences for new clients (e.g., a 'Welcome to Your First Session' series, a 'Post-Workout Recovery Guide'). You plan to sell digital fitness products like a custom workout plan PDF or a meditation audio directly from your email list, without a separate e-commerce store. You value building a loyal community around your fitness expertise, not just sending promotions.
When to Choose Beehiiv
Your main offering is a popular weekly or daily fitness newsletter, providing workout routines, nutrition advice, or wellness insights. You want to rapidly grow your email list of health-conscious subscribers using built-in referral programs (e.g., 'refer a friend, get a free stretch guide'). You aim to monetize your fitness content directly through ads (e.g., featuring protein powder brands or fitness apparel) or by offering a premium, paid subscription for exclusive workout videos or detailed meal plans. You see your fitness newsletter as a content business that can stand on its own, not just a tool for booking one-on-one sessions. You want tools to help other fitness influencers or wellness blogs promote your content.
The Verdict
For basic client communication, class announcements, or simple promotions for independent trainers, Mailchimp is a solid, free starting point. For fitness coaches and yoga instructors who build client relationships through tailored content, sell online programs, or offer digital products, ConvertKit is the clear winner. If you're focused on building a large audience around a fitness newsletter, monetizing content, and using built-in growth tools, Beehiiv is your best bet. Avoid Mailchimp if you plan to heavily automate client journeys or sell complex digital fitness products; its structure isn't designed for detailed client segmentation or advanced funnels.
How to Get Started
Mailchimp: Sign up for the free plan, import your current client list, and send your first 'Welcome to My Practice' email or 'This Week's Class Schedule' campaign. ConvertKit: Start with their free plan, build a landing page to offer a 'Free 5-Day Core Challenge' to collect new leads, then set up an automated three-email welcome sequence for new sign-ups. Beehiiv: Create your fitness publication, design a template for your weekly 'Wellness Wisdom' newsletter, and set up a referral program to reward subscribers for sharing your content.

FREQUENTLY ASKED QUESTIONS
Is Mailchimp's free plan worth using?
For a business just starting email marketing, yes. The free plan allows 500 contacts and 1,000 sends per month. The limitations (no automation on free, Mailchimp branding) become restrictive as you grow, but it is a valid starting point.
How does Beehiiv make money?
Beehiiv charges a monthly fee ($39-99) and takes a revenue share on ads booked through their ad network. They do not take a cut of paid subscriptions.
Can I move my list between platforms?
Yes. You can export subscribers as a CSV and import them to any platform. Some subscribers may need to reconfirm if GDPR compliance requires re-consent. Sequences and tags do not transfer and need to be rebuilt.
