Case Study: Siit achieves 3x higher reply rates and 78% fewer spam complaints with Topo

When Your Domain Gets Blacklisted by Your Own Ideal Customers

The customer, Siit, a startup building a product for IT teams, faced a critical challenge where their own ideal customers were blacklisting their email domain. Their prospecting efforts to IT managers were failing as their emails were consistently flagged as spam, making scalable outreach impossible. They partnered with the vendor, Topo, to recover their domain reputation and rebuild their outbound sales strategy.

Topo implemented a sophisticated email infrastructure with full authentication and multi-channel orchestration. They shifted Siit's targeting to focus on specific intent signals and helped craft highly credible messages that resonated with technical buyers. As a result, Siit achieved a 3x improvement in response rates from IT leaders, a 78% reduction in spam complaints, and a 70% decrease in time spent on prospect research.
