Coming Soon: AI Summaries of Your List Quality

Technical Email Signals, Turned into Your Next Best Action

InboxValid’s verification engine stays the source of truth. AI will help explain those results, spot patterns across a list and prioritize what to fix, without inventing a mailbox verdict.

Deterministic ChecksGrounded ExplanationsYou Stay in Control

Explain Every Verdict

Turn mailbox signals, provider responses and risk flags into a plain-language recommendation for each address.

Know Whether to Send, Review or Suppress

Summarize List Quality

Surface provider patterns, risky segments and the safest export strategy after a bulk verification run.

Prioritize Deliverability Fixes

Translate authentication and DNS findings into a focused remediation plan for your sending domain.

Fix the Highest-Impact Issue First

Clear Checks. Honest Results.

Built to Help You Make a Safer Send Decision

InboxValid is a Deep Scan Email Validation Platform. It improves your list and shows you what needs attention.

No Email Is Sent

We check the receiving mail server. We do not send a message to the address you verify.

Every Result Has Context

See status, trust score and the reason together. Unknown stays unknown instead of becoming a guess.

You Decide What Stays

Keep valid addresses, review catch-all and risky results, and separate invalid contacts before sending.

Your List Has a Clear Purpose

Your contacts are processed to return verification results, not to create marketing lists for other customers.

Inside Every VerificationDeep Checks Behind Every Result

We look beyond the format of an address. Domain records, MX routing, provider behavior and receiving-server responses all contribute context to the status and risk signals you see.

Need technical details? Read our Help Center

Accuracy & Confidence

Understand the Result. Know What to Do Next.

A useful check explains uncertainty. Review the status, trust score and reason together.

Result	What It Means	Your Next Step
Valid	The checks indicate a usable address.	Include it in your reviewed list; delivery still depends on your sender setup and campaign.
Invalid	The address failed verification.	Remove it from your send list or correct it before checking again.
Catch-All	The domain accepts mail for addresses that may not have a real inbox.	Review separately; acceptance is not proof that a person will receive your email.
Risky or Disposable	The address has signals that deserve extra attention.	Review the reason and decide whether it fits your campaign.
Unknown	The check could not reach a confident answer.	Keep it separate and check again later; do not treat it as valid.
