Customers.ai (formerly MobileMonkey) vs Skai

Pick Customers.ai if you have traffic and no way to reach most of it. It is a test you can run cheaply: use the trial, measure the identification rate on your own audience, and see whether those contacts engage. It suits e-commerce brands on Klaviyo that also advertise on Meta and Google.

Super CAPI sends server-side events to Meta, which helps with tracking. The caveat is privacy. Contacting people who never gave you their details is a legal question, and the rules differ between the United States and Europe. Check your privacy notice and your basis for outreach before you send.

Pick Skai if you manage large budgets across retail media, paid search and paid social, and each channel has its own console and its own reports. It gives you one view, bidding rules across channels and reporting on the whole mix. It is strong where retail networks matter.

The entry tier assumes ad spend in the millions each year, and commitments are annual. It also needs a team that uses it every day, builds rules and reviews recommendations. Without that, you pay for features nobody uses. Smaller programmes go through reseller partners, so check that your spend justifies it before you take a demo.
