Case Study: Boozt.com achieves near‑100% inbox placement and higher open rates with Validity's Sender Certification

Boozt improves relationships with target mailbox providers through Sender Certification and IP address warm-up

Boozt.com, a leading Nordic online fashion retailer with 5 million monthly visitors, faced falling inbox placement after moving from a shared to a dedicated IP—overall IPRs dropped below 80% and Microsoft deliveries fell to 0%, affecting roughly 40% of subscribers. Boozt.com engaged Validity to address low inbox placement and to implement an IP warm‑up and Sender Certification strategy.

Validity implemented a comprehensive IP warm‑up and enrolled Boozt.com in its Sender Certification program, reducing filtering and improving sender reputation. The results were immediate and measurable: Microsoft IPR rose from 0% to 100%, overall IPR improved from 80% to 99%, open rates increased from 20% to 35%, and Boozt.com saw over 1 million SEK in additional revenue per month.
