Where each one falls short

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

Google Optimize

  • Google Optimize and Optimize 360 were sunset and are no longer available as of September 30, 2023
  • Any experiments and personalizations still running on that date were ended by Google
  • Google directs former users to third-party A/B testing tools, naming AB Tasty, Optimizely and VWO, rather than a replacement Google product

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

Google Optimize: Is Google Optimize still available?

No. Google Optimize and Optimize 360 were discontinued as of September 30, 2023. Google recommends third-party A/B testing integrations such as AB Tasty, Optimizely, and VWO as replacements.

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.

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.

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.

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.
