Address structure and domain
Find malformed addresses and review whether the domain is configured to receive email before deciding what belongs in your sending list.
Practical email validation
Validate email lists before you sendKnow what to use, remove, or review
Turn a pasted list or CSV into clear verdicts with the supporting evidence kept in view. Peopledat helps you make a better list decision without promising what receiving servers cannot reveal.

What it means
Email validation turns technical signals into a usable list
A well-formed address can still point to a domain that does not accept mail, a mailbox a server will not confirm, or a condition such as catch-all or disposable. Peopledat brings the available signals into one dashboard so you can apply your own sending policy instead of relying on an unexplained score.

Mail-server response
See SMTP connectivity and mailbox-response signals when the receiving server is willing to provide them.

Conditions that need review
Keep catch-all, disposable, role-account, inbox-full, disabled, and unknown conditions visible instead of flattening them into a misleading yes or no.
The dashboard workflow
From raw list to a usable decision
No developer integration is required. Work through a list in the browser and keep the result attached to the address.
- 01
Paste or upload
Sign in to the dashboard, create a list, then paste email addresses or upload a CSV. Keep the original file as your source of record.
- 02
Run verification
Peopledat processes the list and returns verdicts with the supporting signals available for each address.
- 03
Review and export
Inspect uncertain and risk-marked results, decide what fits your sending policy, and export the list for your next workflow.
Read the result
Verdicts are decision support
Keep the verdict and its context together. A single label cannot account for consent, engagement, sender reputation, or a receiving server changing its behavior later.
Safe
The available checks support using the address. It is a positive verification signal, not a promise of delivery or inbox placement.
Invalid
The checks found a strong reason not to use the address, such as invalid structure, domain, or mailbox response.
Review the signal
Catch-all, disposable, role-account, inbox-full, disabled, and similar conditions need a policy decision rather than one universal rule.
Unknown
The receiving system did not provide a decisive answer. Peopledat does not deduct credits for results classified as unknown.
Put the result to work
Use validation where it changes a list decision
Prepare a campaign import
Separate strong positive results from invalid and uncertain addresses before moving a list into your sending platform.
Triage an older list
Use current verification signals to review addresses collected months or years ago without pretending verification replaces consent or engagement data.
Keep uncertainty explicit
Hold unknown and policy-sensitive results for review or later retesting. Unknown verdicts do not consume Peopledat credits.
Clear limits, so you can use the result responsibly
- Email verification cannot guarantee delivery, inbox placement, engagement, or future mailbox availability.
- Receiving servers may hide mailbox status, throttle checks, or accept every recipient. Those cases can remain uncertain.
- Risk flags are context, not proof of fraud, consent, or a person's intent.
- Use the dashboard for list work, the versioned REST API for server integrations, or the origin-bound widget for advisory form checks. No official SDK is required.
Questions, answered plainly
Frequently asked questions
What does email validation check?
Peopledat presents available structure, domain, mail-server, mailbox, and risk signals for each address. The exact evidence varies because receiving systems do not all disclose the same information.
Are email validation and email verification different?
The terms are often used interchangeably. In practice, the useful distinction is between a simple format check and a broader review that includes domain, mail-server, and mailbox-related signals.
Does validation guarantee that an email reaches the inbox?
No. A positive result reflects the evidence available at verification time. Delivery also depends on future mailbox state, receiving-server policy, sender reputation, message content, and recipient engagement.
How do I validate a list in Peopledat?
Use the dashboard to paste addresses or upload a lossless CSV, then review and export the results. Integrations can use the versioned REST API for one address or an asynchronous job, signed webhooks for completion events, or the origin-bound browser widget.
Bring a list. Leave with a clearer decision.
Paste addresses or upload a CSV, review the evidence behind each result, and pay nothing for verdicts classified as unknown.
