How they work

Flowium is a founder-led agency started by Andriy Boychuk in 2017 and known for its Klaviyo training content. It does not publish its team size or prices on a page we could verify, so you will learn its working model on a call.

Huge Win Media is about a dozen people working only in Klaviyo. Each client keeps the same marketers, writers, and designers every month. Week 1 is a full audit of every flow, campaign, and segment. Week 2 rebuilds the highest-impact flows. Week 3 starts the campaign calendar. After that it runs on weekly syncs, monthly reporting, and a quarterly A/B testing roadmap.

Bottom line: Both work on Klaviyo. The difference is in pricing, guarantees, and how the work is packaged.

Klaviyo partner tier and channels

Flowium lists Klaviyo Master Elite (per Flowium's own content). Huge Win Media is a Klaviyo Partner and is not Master Elite. If partner tier is part of your buying criteria, Flowium wins this one.

On channels, Flowium covers email and SMS on Klaviyo. Huge Win Media covers email on Klaviyo, with SMS and postcards as add-ons. If you need channels beyond that, Flowium is the better fit.

Pricing and total cost

Huge Win Media publishes its pricing. Plans start at $1,000 per month. Campaigns cost $100 to $200 per email depending on format: text, drag-and-drop, or full graphic design. Flow builds are one-off projects quoted after a free audit, starting from $3,500. The rate is lower when your team handles strategy or account management. The first flow design has a 7-day money-back guarantee, and monthly plans have no minimum term.

Flowium does not publish its prices, so you need a call to compare.
