Email DNS & DMARC Change Monitor
Pricing
from $2.50 / 1,000 domain checks
Monitor SPF, DMARC, MX, and DKIM records, detect configuration changes between runs, and flag email security regressions.
Domains to check. Accepts bare domains (example.com), URLs (https://example.com/path) or email addresses (user@example.com) - the hostname is extracted. Maximum 100 domains per run.
[ "apify.com"]scan = one-off check, never touches the stored baseline. monitor = compare against the stored baseline for this monitor ID, report drift, then update the baseline.
Required in monitor mode. Identifies an isolated baseline namespace so several monitors can coexist in one account. Allowed characters: letters, digits, dash and underscore (1-64 chars).
DKIM selectors to probe on every domain, e.g. 'google', 'selector1', 'k1'. DKIM selectors are NOT enumerable via DNS - only the selectors you list here are checked.
[]Extra DKIM selectors for specific domains, e.g. {"example.com": ["selector1", "selector2"]}. Merged with the global list.
{}Per-query DNS timeout. Lower values finish faster but raise the UNKNOWN rate on slow authoritative servers.
How many domains are resolved in parallel. Keep it moderate to avoid hammering resolvers.
