Address verification and message review answer different questions

A subject-line or content review does not establish whether a recipient address can receive mail. Address verification adds technical status information, while your team reviews relevance, contact permissions and the message itself.

Check addresses

Verify one address or a CSV list and wait for completed results before relying on them.

Review catch-all results

A catch-all result leaves mailbox reachability uncertain. Keep it separate from Valid and Invalid results.

Reconcile bulk results

Match exported statuses to source records, including duplicates and unresolved checks.

From source list to reviewed outreach records

Use completed results and source context to decide which records are ready for the next step.

Prepare your records

Use addresses you own or are authorized to process. Keep source IDs, exclusions and relevant prospect context.

Verify and review

Run the authorized checks and segment Valid, Invalid, Catch-all and Unknown results.

Decide what happens next

Approve records under your contact policy before importing or sending. Verification does not guarantee inbox placement.

Review before sending

Use verification results to identify invalid addresses and separate uncertain records. Authentication, message relevance, contact permissions and provider requirements still need attention.

Final verification statuses to review

Measure observed outcomes

Review actual delivery failures, complaints and replies after sending. Verification does not remove automated opens from campaign reports or make an A/B test statistically conclusive.
