What it lists
Sender Score returns a 0-100 reputation score derived from Validity's data partners. It is consulted as an advisory signal, not a hard blocklist.
Who gets listed
All scanned IPs receive a score; lower scores indicate poor reputation.
Reputation impact
Score under 70 starts to correlate with deliverability problems; under 50 is a strong red flag.
How to delist
Improve list hygiene, authentication, and engagement metrics; the score updates over time. There is no manual delist.
