Is “Sender Score” still relevant?

Still Useful. **Sender Score** (now from **Validity**) provides **IP reputation** insight but is not the only or most important metric. Major providers have their own reputation systems.

**Gmail** Postmaster shows **Gmail** specific reputation, which matters most for **Gmail** delivery. **Sender Score** indicates how **Validity**'s data sees your IPs.

Use **Sender Score** as one data point among many. Monitor provider specific metrics where available. No single score tells the complete deliverability story.
