How Email Verification Works

Email verification reviews available address, domain and mail-server signals before you rely on an email address. Start with one contact or a whole list, then use the result to decide your next step.

01

Add an address or a list

Check one authorized address, or prepare a CSV from your CRM, newsletter, event or prospecting workflow. Keep the original file and source row IDs; convert TXT lists to CSV locally.

02

Review the result

See Valid, Invalid, Catch-all or Unknown for one address, or review the same result groups across your list.

03

Take the next action

Move valid contacts forward, suppress invalids and review uncertain results. For bulk checks, export the segments you need for your next campaign or CRM import.

A big list can hide a small leak

Most list problems do not look dramatic inside a spreadsheet. They show up later as bounces, messy segments, wasted sends, and teams wondering why a campaign underperformed.

Raw CSV workflow

A raw export can make a team feel ready because the file looks full. Under the surface it mixes active buyers with stale roles, old jobs, throwaway signups, invalid domains, duplicates and unresolved catch-all rows. The campaign starts with volume, but not clarity.

Verified list workflow

The same file becomes clear result groups before the send. Teams see which rows are Valid, Invalid, Catch all, or Unknown, then decide what moves forward, what gets suppressed and what needs review, instead of treating the whole CSV as one equally safe audience.

Review list quality
before you send

Use verification results to separate invalid and uncertain addresses before a campaign. Review them alongside your sending practices: verification does not guarantee future delivery or inbox placement.

Email Validator Results:
Valid, Invalid, Catch-all, Unknown

Each address receives one of these results, whether you check it individually or as part of a list.
Use the status to decide what to send, suppress or review.

Status

What it means

Typical handling

Valid

The address passed the checks available at the time of verification.

Continue under your contact policy. A valid result does not establish consent or guarantee future delivery or inbox placement.

Invalid

The address doesn't exist or the domain can't receive mail.

Suppress. Sending here is what causes hard bounces.

Catch all

The domain accepts mail for any address, so the mailbox can't be confirmed.

Keep separate for review. A catch-all result does not confirm the individual mailbox or permission to contact it.

Unknown

The server gave no definitive answer: greylisting, rate limiting or anti-probing.

Hold for review. These never cost you a credit.

Verify One Email vs Bulk List

Check one address before your next action, or verify a whole list before a campaign or CRM import. Choose the workflow that matches the number of contacts you need to review.

EmailAwesome Verifications

01

Verify one email

Enter one address and review the credit information before running the check. Wait for a final status and record its time before updating a contact or preparing your next message.

02

Verify a bulk list

Keep your original list and upload a working CSV. Review headers, excluded rows and the credit estimate against your balance before confirming. Wait for completion before exporting results.

Built for real list work

CSV list preparation

Convert TXT to CSV locally and check the current sample format. Keep stable source IDs and a duplicate map so every exported row can be traced back to your original list.

Segmented result groups

Separate Valid, Invalid, Catch all and Unknown results. Track excluded duplicates, pending checks, failures and missing results separately; an upload or timeout is not a Valid result.

Reconcile before re-importing

Inspect the export columns and match results to source IDs. Exported rows, unique addresses and charged validations may differ. Keep duplicate exclusions so the same contact is not sent to twice.

For guided preparation with a compatible AI agent, review the EmailAwesome product skill reference. It provides instructions; account access and completed verification remain separate steps.
