Spacebrain Email Verification
Check address quality where your customer data lives. Bring individual checks and bulk lists into one review process, understand each result, and keep exports, history and credit usage connected.
From source to result
Check the list.
Know your next move.
A focused flow from the emails you have to the results you can act on.
Review the check
Understand the input and estimate before running verification.
- Identify duplicate and invalid entries
- Reuse eligible recent results
- Review the maximum credit estimate
Use the results
Separate the results you need and keep the evidence close.
- Filter by result status
- Inspect an individual email
- Export a reviewed result set
Read the result
A status.
And what to do with it.
Keep clear results separate from addresses that need another look. Verification helps assess quality; it does not guarantee delivery or replace permission to email.
Valid
The check returned a positive result. Review consent and campaign suitability before sending.
Invalid
Exclude from your send-ready list and correct the address at its source where possible.
Risky
Review separately. An address can carry uncertainty even when it appears usable.
Unknown
The check was inconclusive. Keep it unresolved and review available retry options.
The expanded verifier
Less repeat checking.
More useful history.
The new workspace brings the full verification process together. It is preparing for release alongside the product update.
Reuse recent results
Eligible fresh results can be reused across sources in your workspace. See what needs a new check before spending credits.
Return to your work
Reopen a run to inspect progress, filters and results. Look up an exact email to review its verification history.
Understand credit usage
Review the estimate before a run and the receipt afterward. Keep the source, result and credit usage connected.
Questions & answers
Practical answers for planning the work.
What does email verification tell me?
Verification assesses address quality and returns a status you can use when reviewing a list. A valid result is not a guarantee that a future message will reach the inbox, and verification does not establish consent to receive marketing.
Can I verify a single email or a whole list?
The verifier supports individual checks and pasted emails, CSV/TXT files, and workspace audiences. Review the source and estimate before starting. The expanded bulk workspace is preparing for release; contact us to confirm access.
Do I pay to check the same address again?
Fresh reusable results can be used across sources in the workspace without a new provider check. The review step distinguishes reusable results from emails that need a check. Review the current estimate and resulting receipt for your workspace’s charges.
How should I treat risky or unknown results?
Review risky addresses separately before sending. Unknown means the check could not establish a definitive answer; it is not a valid result. Keep unresolved addresses out of a send-ready export unless you have reviewed them.
Can I export the results?
The expanded verifier includes filtered exports, per-email detail and run history. Choose the result set you need and review it before exporting. An export does not automatically subscribe contacts or launch a campaign.
Where do I find it?
Current verification entry points are in Email Audiences and CRM Data Quality. The expanded Email Verifier workspace brings sources, results, email history and credit usage together under Email.
