Built-in checks for healthier email performance

Every upload is evaluated through practical validation checks so your team can quickly separate safe records from risky ones.

Disposable domain detection

121,000+ known throwaway providers checked on every email. Mailinator, Guerrilla Mail, TempMail — flagged immediately with a deliverability score under 10.

Domain typo correction

Catches gmial.com, yaho.com, hotmai.com and 20+ common transpositions. Returns a suggested_domain so you can fix lists before they bounce.

Role account detection

50+ role prefixes identified — info@, noreply@, billing@, careers@, abuse@. Shared inboxes that rarely convert and often trigger spam filters.

Catch-all server detection

Domains that accept any email — even ones that don't exist. We flag them as risky with a ~60 deliverability score and tell you exactly why.

SPF & DMARC signals

Every domain is checked for email authentication records. Missing SPF/DMARC signals an insecure domain. Permissive SPF (+all) is flagged separately.

Spam risk score

Every email gets a spam risk score from 0–100 based on signals that predict inbox placement. Low risk (75+) means safe to send. Very high risk means your campaign reputation is at stake.

Send recommendation

A plain-English decision per email — Send, Send with Caution, Review, or Don't Send. Built from all signals combined so you don't have to interpret scores yourself.

Deep Analysis — domain legitimacy

For every unique domain in your list, we check website presence, SSL, domain age, safe browsing status, mail provider, and match against our 22M+ company intelligence database to confirm the business is real.

Deliverability score

Every email gets a 0–100 score combining all signals. 90+ is safe to send. Below 40 is high risk. Not a black box — each score maps to specific signals.
