Pricing

  • Pricing model: Primarily monthly retainer pricing for ongoing email/SMS marketing management, with tiered package levels based on monthly email volume and hours dedicated; also offers one-time project work (e.g., Foundational Flow Setup) and consulting-style monthly packages. Core agency engagements appear to be custom-quoted but publicly surfaced through directory package snapshots.
  • Starting price: $1,000 / month
  • Typical range: $6,000-$10,000 / month
  • Billing: Monthly recurring billing for ongoing services; auto-renewing month-to-month by default. Flowium also bills for one-time projects and can charge per additional email beyond plan limits.
  • Contract terms: Auto-renewing month-to-month with a 60-day cancellation period. Discounts: 10% off for 6-month agreements and 20% off for 12-month agreements.
  • Free trial: Free consultation call / 30-minute retention strategy session is offered, but no free trial of paid services was found.

What's included

  • Dedicated onboarding with a Flowium team
  • Email platform / ESP setup and management
  • Custom retention strategy
  • Custom creatives, copy, and design
  • Monthly reporting
  • Email testing and performance optimization
  • Email automation strategy creation and implementation
  • Campaign calendar creation and implementation
  • Weekly calls with specialist/team
  • Advanced segmentation
  • Deliverability support
  • For Foundational Flow Setup: strategy, copy, design, testing, and implementation of 7 flows with 20 emails

Flowium itself does not appear to publish a standard pricing page on its own website, but its FAQ confirms the engagement structure: auto-renewing monthly service, optional 6- and 12-month discounts, one-time projects, and per-additional-email charges. Reputable directories expose concrete figures: Clutch shows a minimum project size of $1,000+ and average hourly rate of $100-$149/hr, while also surfacing package snapshots for email campaigns at $6,000-$10,000/month and a verified client spend of $6,000/month; DesignRush separately lists a minimal budget of $1,000-$10,000 and $150/hr. Treat the package dollar amounts as third-party directory-published pricing snapshots rather than prices directly published on Flowium's own site.

Process

How Flowium actually works, reconstructed from customer reviews and third-party write-ups.

A Flowium engagement appears to start with an audit and sales/discovery conversation, then move into a formal kickoff with a dedicated team, account setup/integration, and a roadmap for the first months. From there, Flowium develops strategy, sample emails and creative for approval, then runs ongoing campaign/automation production with weekly communication, iteration based on client feedback, and monthly reporting/optimization.

  1. 1

    Start with an audit and discovery conversation

    Prospects commonly encounter Flowium through an audit-led sales motion: Flowium advertises a free email audit covering flows, campaigns, opt-ins, template design, and KPIs, and Trustpilot reviewers specifically mention receiving an informative, professional audit and having their needs explained on calls before committing.

  2. 2

    Choose a plan and meet the dedicated team in kickoff

    Once a client signs, onboarding begins with a Kick-Off Call where the client meets a dedicated team, aligns on goals, discusses creative expectations, and sets timelines. Flowium’s materials consistently describe a team-based delivery model rather than a solo freelancer-style engagement.

  3. 3

    Set up the account, integrations, and collaboration workspace

    After kickoff, Flowium’s project manager, strategist, and technical staff dig into the account, handle eCommerce integration and account setup, and stand up collaboration infrastructure such as the client dashboard and Slack channel. Flowium also says onboarding includes a deliverability audit to assess sender reputation and inbox placement.

  4. 4

    Build the retention roadmap and monthly email allocation for approval

    During onboarding, Flowium states that its project manager and strategist create a roadmap for the first three months and the year ahead. The strategist then develops the email strategy and monthly allocation between campaigns and flows, with that plan explicitly described as subject to client approval.

  5. 5

    Create showcase samples and core creative before full rollout

    Before producing everything at scale, Flowium says clients receive five showcase emails and a brand-specific automation plan; third-party write-ups similarly describe a sequence of analyzing the current account, creating a few sample emails to finalize copy and design, and only then developing the broader program. This matches review evidence that clients give feedback and Flowium iterates quickly with multiple options.

  6. 6

    Launch campaigns, flows, segmentation, and technical execution

    The live delivery phase includes platform management, automation strategy implementation, campaign calendar creation, segmentation, copy/design production, and ongoing testing/optimization. Flowium’s service descriptions and review summaries repeatedly frame the work as a mix of campaign emails plus lifecycle flows managed by specialists across strategy, copy, design, project management, and technical execution.

  7. 7

    Run weekly check-ins, iterate on feedback, and report monthly

    Once work is in motion, Flowium’s listed process includes weekly calls with the specialist team and monthly reporting. Review evidence on Clutch and Sortlist emphasizes responsive communication, organized project management, on-time delivery, and quick iteration after client feedback, suggesting an ongoing review-and-refine cadence rather than one-off delivery.

Reviews

Flowium has a modest but real third-party review footprint. I found clear listings on Clutch, G2, and Trustpilot; Clutch and G2 are strongly positive, while Trustpilot is mostly positive but includes one apparently mismatched scam complaint that Flowium publicly disputed. I did not find a verifiable company profile/listing for Flowium on Google, Capterra, or BBB in the search results I examined.

    The single visible G2 review is very positive and emphasizes professionalism, responsiveness, and careful handling of questions and privacy concerns. The profile appears inactive/unclaimed, but it is clearly a Flowium listing tied to flowium.com.
