The short version

  • Only Convert has a free tier, so it costs nothing to try first.
  • Each has a real cost: Convert pricing is driven by monthly tested users, starting at $399 per month for 100,000 monthly tested users on Growth and $599 on Pro; Wunderkind pricing is never published and deals are annual with revenue-share terms and a floor, so the effective cost only becomes clear after a year of attributed revenue you have already paid against.
  • They diverge on capability: Convert covers A/B testing, Wunderkind covers Identity resolution network.
  • Prices and features above were last checked on 2 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Convert

  • Pricing is driven by monthly tested users, starting at $399 per month for 100,000 monthly tested users on Growth and $599 on Pro
  • Single Sign-On requires the Pro plan at $599 per month
  • Multivariate testing, multi-page testing, full stack and feature flags, sequential testing and raw test data export are all withheld from the Growth plan
  • Phone support, change history and guided onboarding require Pro
  • The advertised $299 and $420 per month rates require paying the full year up front at $3,588 or $5,040
  • The Enterprise plan is price on request, is only available as an annual plan, and its data segregation feature carries additional costs
  • Listed prices exclude VAT, GST and other taxes, which are added at checkout
  • Above 5 million monthly tested users there is no published rate

Wunderkind

  • Pricing is never published and deals are annual with revenue-share terms and a floor, so the effective cost only becomes clear after a year of attributed revenue you have already paid against.
  • You pay against Wunderkinds own attribution of the revenue it claims to have driven, so the lookback window, credit rules and whether a genuine holdout test is run are commercial terms that materially change your bill and are easy to leave vague.
  • The model needs scale: a site without substantial traffic generates too few identity matches to clear a contract floor, which makes it uneconomic for mid-market retailers however good the pitch sounds.
  • Messaging people who never gave you their email address on your own site carries privacy exposure and brand risk, and it sits uncomfortably with several regulatory regimes and with some consumers regardless of legal defensibility.
  • The identity network is densest in the United States, so a European or Asian retailer gets materially lower match rates and a weaker business case, and the model interacts badly with strict consent regimes such as GDPR.

Answered from the vendors’ own pages

Convert: What is the starting price for Convert?

The Growth plan starts at $399/month (or $299/month billed annually for 25% savings) with 100K monthly tested users, 5 projects, and 5 active experiences per project.

Source
Wunderkind: Is Wunderkind the same as BounceX?

Yes. BounceX rebranded as Wunderkind in 2019; the identity resolution and triggered messaging model is the same lineage.

Convert: What is the difference between Growth and Pro plans?

Both cap at 100K tested users/month, but Pro ($599/month or $420/month annual) adds 30 active projects (vs 5), unlimited experiences per project (vs 5), unlimited domains (vs 10), multivariate testing, full-stack testing, sequential testing, and phone support.

Source
Wunderkind: How is Wunderkind priced?

It is not published. Contracts are annual and structured around a share of revenue Wunderkind attributes to its messages, usually with a minimum commitment.

Convert: How much does the Enterprise plan cost?

Enterprise pricing is available 'on request.' It supports 1M+ monthly tested users (12M+ annually), unlimited projects, experiences, and domains, plus dedicated account manager and custom terms.

Source
Wunderkind: Does it replace my email platform?

No. It runs alongside your existing ESP and adds a triggered channel; it is not a campaign management replacement.

Convert: What is the cost to exceed my monthly tested user limit?

Growth overages cost $399 per 100K additional users. Pro/Enterprise overages cost $699 per 250K additional users. Customers can also upgrade mid-cycle at any time.

Source
Wunderkind: Will it work outside the United States?

Less well. The identity network is concentrated in the US, and consent requirements in Europe reduce both match rates and the legal room to message unidentified visitors.
