Use the sender score lookup to inspect reputation data for a sending IPv4 address. The response includes a score from 0 to 100, a rating and a volume tier. A historical trend and certification flag may also be present. A score is one signal to investigate alongside your bounce rate, complaint rate, authentication and blacklist results; it does not guarantee inbox placement.
Run a one-off lookup at spotzee.com/tools/senderscore-lookup. Extended API calls use your Spotzee credit balance; see pricing for current rates.

​
Check an address

1

Enter the sending IP

Enter an IPv4 address used to send your mail. The lookup does not accept IPv6 addresses.
2

Review the result

Read the score, rating and volume tier. Check the historical trend and certification flag when present. A low score or falling trend is a prompt to investigate the sending activity behind that address.
3

Compare other signals

Check recent bounce and complaint rates, authentication and IP blacklist status before changing your sending plan.
If volume_tier is INSUFFICIENT, treat the score as limited evidence and compare it with your own delivery metrics.
