Arnio vs Retention.com
Is Arnio a Retention.com alternative?
Yes. Retention.com is built to identify anonymous visitors and grow your email list. Arnio is the intent-first alternative: it ranks which shoppers are actually ready to buy and routes only those into your existing Klaviyo, so you convert more without inflating list size or send volume.
Retention.com is known for identifying anonymous website visitors and growing a brand’s email list from that traffic. Arnio starts from a different question: not just who visited, but which of those shoppers are actually ready to buy, and what to do with them next.

How Arnio is different
- Ranks shopper intent from real behavior (product views, repeat visits, cart and checkout activity, ad, email, and SMS engagement) instead of only resolving identity.
- Routes only high-intent shoppers into your existing Klaviyo, so you are not paying to message everyone who happened to visit.
- Acts as a lifecycle layer across the whole journey, not a one-time list-growth tool.
