Adding & Managing Domains

SenderFortify monitors root domains and their subdomains independently. Each root domain counts against your plan limit; subdomains are unlimited.

Root domains

A root domain (e.g. acmecorp.com) is the primary unit of monitoring. Adding a root domain starts the scan cycle for that domain and all its registered subdomains.

Subdomains

Subdomains (e.g. mail.acmecorp.com, marketing.acmecorp.com) are scanned separately from the root on a 6-hour cycle. They must be added manually from the domain's detail view — the scanner runs checks on subdomains you have registered but does not auto-discover them. You can also trigger a manual scan on any individual subdomain at any time. Subdomains do not count toward your domain limit.

Custom DKIM selectors

By default SenderFortify probes a set of common DKIM selectors (selector1, selector2, google, mail, etc.). If your client uses a non-standard selector, add it in the domain's Settings tab under Custom DKIM Selectors. Multiple selectors can be added as a comma-separated list.

Suppressing checks

Individual checks can be suppressed per domain if a finding is a known accepted risk (e.g. a client intentionally uses p=none during a DMARC rollout). Suppressed checks still appear in the dashboard but are excluded from the posture score and will not trigger alerts.

Deleting a domain

Deleting a domain removes all scan history, violations, and alerts associated with it. This cannot be undone. The domain slot is released back to your plan limit immediately.
