Brevo (rebranded from Sendinblue in 2023) is the “all-in-one marketing platform” that personal trainers most often discover through the cost math: a solo trainer comparing Mailchimp’s Essentials tier ($35/month for 2,000 contacts) against Brevo’s equivalent ($9/month for 5,000 emails) and realizing the bundle math doesn’t add up in Mailchimp’s favor. The Brevo Free tier covers contact counts that would cost $50-150/month on competitors. For a personal trainer where email marketing is part of the client retention workflow, that pricing gap compounds across years.
We synthesized 12+ months of Brevo ownership patterns from G2 and Capterra verified-account reviews from personal trainers and small fitness businesses (sample ≥40 reviews with 6+ months of paid or free-tier ownership), certified-trainer community sources (r/personaltraining, r/Coaching aged-account threads filtered for email-marketing platform discussions), Brevo’s published documentation and integration documentation, and the same representative solo-trainer-to-small-studio profile we use across our best email marketing for gyms and best CRM for personal trainers roundups. What follows is the convergent pattern from those sources: where Brevo earns its slot, where the gaps show up, and which trainer profiles should pick it versus the alternatives.
Why you should trust us
We don’t run a lab. We don’t run test newsletters across every platform with statistically-significant subscriber lists. What we have is a systematic methodology for synthesizing the work of the people who do: G2 and Capterra peer reviews from personal trainers and small fitness operators with 6+ months of Brevo ownership, Brevo’s published product documentation and pricing pages, certified-trainer community sources (NASM and ACE forums, r/personaltraining, r/Coaching), trade press coverage on SMB email marketing platforms, and side-by-side comparisons across Brevo + Mailchimp + Kit + Klaviyo + Sender in aggregated owner reports. We present that synthesis through our 5-criteria framework. Where vendor claims and trainer experience diverge, we say so.
One honesty note: Brevo is currently an affiliate partner of ours. The review that follows favors Brevo on the composite for the trainer profile most readers fit, but the rationale is operational (CRM + email bundle, contact-count pricing math, Trainerize integration). Where Brevo isn’t the right answer (personal-brand creators, e-commerce-heavy operations), we say so and recommend the alternative.
What Brevo actually is (and the three things it isn’t)
Brevo is a marketing platform with five core capabilities bundled into one subscription: CRM (contact management with custom fields and pipeline tracking), email marketing (campaigns, templates, segmentation), transactional email (order confirmations, password resets, account notifications), marketing automation (visual workflow builder with conditional logic), and basic SMS marketing (paid per-message). That’s the whole product, and for the personal-trainer use case it’s a clean shape: the contact who joins your newsletter, books a discovery call, signs up for coaching, and gets a renewal reminder all live in one platform with one subscription.
It is just as important to be clear about what Brevo is not, because the email marketing category is full of adjacent tools that get confused with it.
Brevo is not a creator monetization platform like Kit (ConvertKit). It doesn’t natively sell digital products, host paywalled newsletters, or run subscription-based content. For personal trainers selling online coaching programs as info products via email funnels, Kit’s creator-focused workflow fits better.
Brevo is not an e-commerce marketing platform like Klaviyo. It doesn’t have the deep Shopify/WooCommerce integration depth, the e-commerce-specific automation triggers (abandoned cart, post-purchase sequences with order data, behavior-based segmentation tied to purchase history), or the deliverability tooling Klaviyo built for high-volume e-commerce sends. For gyms selling significant supplements, apparel, or digital programs online, Klaviyo wins on e-commerce capability.
Brevo is not a sales-CRM-with-pipeline-management-focus like HubSpot or Salesforce. It has CRM capabilities but the contact management workflow is email-marketing-first with pipeline tracking attached, not pipeline-tracking-first with email attached. For sales-driven operations (B2B coaching businesses with long sales cycles), HubSpot’s CRM polish is the workflow fit.
Buy Brevo for the personal-trainer-email-marketing-and-light-CRM combination. For creator monetization, e-commerce automation, or sales-driven CRM, it’s the wrong shape.
Where Brevo wins clearly
Contact-count pricing is structurally cheaper at scale. Brevo prices on send volume; Mailchimp prices on contact count. For a personal trainer growing a list from 500 to 5,000 contacts over 2 years while sending a weekly newsletter, the cost trajectory looks like this per current vendor pricing:
| Contact count | Brevo monthly cost | Mailchimp Essentials monthly cost |
|---|---|---|
| 500 | $0 (Free tier) | $13 |
| 1,000 | $0 (Free tier) | ~$20 |
| 2,000 | $9 (Starter, 5k emails/mo) | ~$35 |
| 5,000 | $19 (Starter, 20k emails/mo) | ~$75 |
| 10,000 | $35 (Business, 40k emails/mo) | ~$135 |
At 5,000 contacts, Brevo is ~75% cheaper than Mailchimp Essentials at comparable send volumes. The cost advantage compounds across 18-24 months as the list grows, which is the structural argument for Brevo over Mailchimp for any growing personal-trainer operation.
CRM + email marketing in one platform at no upgrade cost. This is the bundle math that surprises most trainers. Brevo’s Free tier includes both CRM and email marketing capabilities; the upgrade path adds higher send volumes (for email) or more CRM seats (for sales pipeline use cases), but the basic dual-functionality is on Free. Most competitor platforms (Mailchimp, HubSpot, Kit) require paid tiers or separate platform subscriptions to combine CRM + email marketing. For a trainer where both are part of the workflow, Brevo’s bundle is roughly equivalent to paying for two separate platforms at competitor rates.
Trainerize integration via direct API. The integration matters operationally because contact lists flow naturally between gym management software and email marketing. New clients added in Trainerize appear in Brevo for email marketing without manual export. Convergent owner reports from multi-trainer studios describe the integration as the operational win that justifies Brevo over alternatives where the integration goes through Zapier (Brevo + Mindbody/Vagaro/ClubReady) or manual export (Brevo + most other gym software). For trainers on Trainerize specifically, this is a meaningful workflow advantage.
Automation depth is adequate to good for typical trainer workflows. The visual automation builder handles the workflows personal trainers actually need: welcome sequences for new clients, renewal reminders 7 days before contract end, lapsed-client win-back after 30 days of inactivity, milestone celebrations (first session, 10th session, anniversary). The builder is consistently flagged in G2 + Capterra reports as functional and reliable, with the caveat that more complex conditional logic requires moving into higher paid tiers. For typical trainer use, the Free or Starter tier covers the automation workflow.
Deliverability sits in the same bracket as Mailchimp and ActiveCampaign. Brevo’s inbox-placement rates per aggregated 6+ month owner reports cluster in the 95-97% range for properly-configured senders (SPF, DKIM, DMARC set up, list hygiene maintained). Klaviyo wins on deliverability for high-volume e-commerce sends, but for personal-trainer-scale operations (under 50,000 sends/month), Brevo’s deliverability is reliably above the threshold where it would be a decision factor.
Where Brevo hurts your workflow
UX learning curve is steeper than Mailchimp. Convergent G2 + Capterra reports describe Brevo’s interface as denser and less intuitive than Mailchimp’s for first-time email marketing users. The navigation is deeper (more clicks to reach common actions), the visual design is functional but visibly less polished, and the first-week onboarding is longer per owner reports. For trainers who value the smoothest-possible first-week experience, Mailchimp has a subjective UX edge. For trainers comfortable trading a steeper learning curve for the long-term cost and bundle advantages, the UX gap closes after 2-3 weeks of regular use per owner reports.
Automation depth caps below Klaviyo and ConvertKit (Kit). Brevo’s automation handles 90% of personal-trainer workflows cleanly. For the 10% of operators running more sophisticated automation (multi-channel sequences combining email + SMS + transactional triggers, advanced behavior-based segmentation tied to specific user actions inside the trainer’s online platform, multi-step sales funnels with conditional logic across 10+ branches), Brevo’s builder hits limits that Klaviyo and Kit don’t. For trainers running creator-style sales sequences, Kit’s workflow is the better fit. For trainers running e-commerce automation, Klaviyo’s depth is the better fit. For typical trainer use, Brevo is sufficient.
Segment-building UI is functional but slower than competitors. Building complex audience segments in Brevo takes more clicks than the equivalent in Mailchimp or HubSpot per convergent owner reports. The capability is there (Brevo supports custom-field-based segments, behavior-based segments, list-membership segments), but the UI is denser. Trainers running heavy segmentation should evaluate whether the UI friction is worth the cost savings.
Support tier walls on response time. Brevo’s support quality varies by tier per aggregated owner reports. Free tier and lowest paid tiers get email support with 24-72 hour response times. Higher paid tiers get faster response and chat support. For trainers on Free or Starter who need fast support during a deliverability issue or migration blocker, the response delay can be frustrating. Mailchimp’s tier-based support quality follows a similar pattern (paid tiers get better support), so this is industry-standard rather than Brevo-specific, but worth noting before committing.
Pricing math for a personal-trainer profile
For a typical solo personal trainer with 500-2,000 active contacts sending a weekly newsletter plus monthly renewal-reminder sequences, the realistic Brevo cost over 12 months:
- Months 1-6 (list growing from 500 to 1,500 contacts): Free tier covers the workflow at $0/month
- Months 7-12 (list at 1,500-2,500 contacts, send volume crossing 300/day during campaign weeks): Brevo Starter at $9/month ($108/year)
Total year-one Brevo cost: roughly $54-108 depending on when the upgrade triggers.
Equivalent Mailchimp Essentials cost over the same 12-month window:
- Months 1-3 (under 500 contacts): Free tier
- Months 4-12 (500-2,500 contacts): Mailchimp Essentials at $13-50/month depending on contact tier (~$400 year-one estimate)
Total year-one Mailchimp cost: roughly $400-600.
The gap is substantial for moderate-scale operations. At larger contact counts (5,000+), the gap widens. At very small operations (under 500 contacts), both platforms are free and the cost question is irrelevant.
The bundle math (Brevo bundles CRM at no extra cost; Mailchimp’s CRM-grade features start at separate paid tiers) makes Brevo cheaper still for trainers who use both. Most personal trainers do.
What Brevo is missing that competitors have
The honest gap inventory per convergent G2 + Capterra owner reports:
Creator-monetization workflow. Brevo doesn’t natively sell digital products, host paywalled newsletters, or run subscription-based content. For trainers selling online courses or info products via email funnels, Kit’s creator-focused workflow wins.
E-commerce automation depth. Brevo’s e-commerce integrations exist but lack the depth Klaviyo offers. Trainers running serious online retail alongside their in-person business should evaluate Klaviyo for the e-commerce-specific capabilities.
Native SMS marketing at scale. Brevo includes basic SMS marketing (paid per-message) but isn’t a serious SMS-first platform. For trainers running heavy SMS campaigns, dedicated SMS platforms (Postscript, Attentive) are the workflow fit.
Best-in-class transactional email deliverability. SendGrid, Postmark, and Mailgun all beat Brevo on transactional-email deliverability for high-volume operations. For trainers running their own software platform that needs to send millions of transactional emails (rare for personal trainers, but exists for some online-platform operators), dedicated transactional providers win.
Multi-language support for international markets. Brevo has some multi-language capability but isn’t the category leader. International operators evaluating European or multi-region operations should check current capability.
The verdict
For most personal trainers and small fitness businesses where email marketing is part of the workflow, Brevo is the convergent recommendation. The pricing model (send volume not contact count) scales gentler than Mailchimp at any list growth trajectory. The CRM + email marketing bundle eliminates the separate-platform decision. The Free tier covers the workflow indefinitely for many solo trainers. The Trainerize integration is the operational win for multi-trainer studios. The UX learning curve and automation depth caps are real but acceptable trade-offs at typical trainer scale.
For personal-brand trainers focused on creator monetization (selling online courses, info products, paid newsletters), Kit is the better workflow fit. For gyms with significant e-commerce alongside in-person, Klaviyo wins on e-commerce depth. For operators already on Mailchimp under 500 contacts where migration isn’t worth the effort, Mailchimp Free is fine until the list grows past 500 contacts (then the cost math forces a re-evaluation).
The mistake to avoid is defaulting to Mailchimp because the brand is most recognizable. Most personal trainers growing past 500 contacts find Mailchimp’s pricing model compounds against them within 12 months. Doing the cost math up front (or once the list crosses 500 contacts) typically points to Brevo for the trainer profile most operators fit.
