Ongoing monitoring
Follow each provider result, then decide what to do
For cold outreach teams, growth marketers, and transactional email senders, keep watched sending domains and IPs, provider outcomes, and check history in one workflow.
Add a sending domain or IP as a watched asset. Review its current results from supported blocklist providers as checks are recorded.
Results stay separate by provider: listed, clear, or unavailable. Saved check history and listing transitions help you see which outcomes changed and when.
With provider-failure email alerts enabled, a newly saved manual check with lookups that could not return a result can send a link to that check. Review the provider outcomes, then rerun to save fresh results.
Manual reruns check providers again; they do not change DNS or sending settings. Reruns require a paid plan.
