The one-line difference: Validity (Everest, Sender Score) is an enterprise deliverability and reputation suite built on proprietary data and ISP relationships. ToolTrusted is the independent, transparent alternative: deterministic, explainable, accessible intelligence about the infrastructure that determines deliverability — without the enterprise price or the black box.

Which to choose
Choose ToolTrusted when…
you want independent, transparent, deterministic intelligence about your email infrastructure — where you can trace every verdict — at an accessible price.
Choose Validity when…
you need enterprise-grade proprietary reputation data, ISP relationships and the broad commercial suite that comes with them.
The distinction: Validity’s strength is proprietary reputation data you can’t see the inner workings of; ToolTrusted’s strength is a glass-box — every verdict is measured, deterministic and traceable to a rule and evidence, from a vendor that sells you nothing to fix. We measure the infrastructure that determines deliverability, not inbox placement.
