Reduce hard bounces

Suppress invalid and weak addresses before a campaign damages future inbox placement.

Protect sender reputation

Segment risky contacts with readable score, state, reason, and risk flags.

Avoid wasted sends

Clean old imports, lead lists, and signup exports before paying your ESP to send to bad rows.

Workflow

From raw CSV to cleaner campaign list.

Use ValidEmail as a practical list hygiene step before your next newsletter, launch, cold outreach sequence, or CRM import.

Upload CSV

Start with the list you already exported from your CRM, form tool, or ESP.

Verify Each Address

Check syntax, domain, MX, mailbox, disposable, role, free-provider, accept-all, and tag signals.

Review Categories

Separate deliverable contacts from risky rows, invalid addresses, and addresses that need human review.

Export Clean Results

Download the full result file or choose a filtered export for your campaign goal.

Detection checklist

Signals your marketing team can act on.

Technical checks are translated into export fields that help decide what to send, suppress, review, or re-verify later.

Syntax and typo signals
Domain and MX records
Mailbox/server response
Disposable addresses
Role-based addresses
Free-provider addresses
Accept-all domains
Plus-address tags

Campaign outcomes

Cleaner lists make the next send easier to trust.

Before a newsletter

Remove obvious invalid addresses before the send and keep reporting cleaner after launch.

Before sales outreach

Prioritize deliverable leads and review role-based inboxes before sequencing.

Before a CRM import

Tag risky, disposable, and accept-all records before they enter downstream automations.

Bulk pricing

Bulk email verification credits for every list size.

Start with the package that matches your CSV size, then export cleaner contacts without subscriptions, contracts, or monthly minimums.

FAQ

Bulk email verification questions.

Which file formats are supported?

The web upload flow supports CSV files up to 50 MB.

How fast will my list be processed?

Processing time depends on list size, mailbox responses, and queue activity. Your dashboard shows job progress.

Do you send emails to verify addresses?

No. ValidEmail checks deliverability signals without sending a message to the address.

How often should I clean a list?

Clean lists before important campaigns, after imports, and whenever a list has not been contacted recently.

What happens with accept-all addresses?

Accept-all addresses are flagged as limited-certainty contacts so you can review, segment, or suppress them.

Can I delete uploaded lists?

Signed-in users can manage bulk jobs from the dashboard, including deleting eligible lists.

Can I export only deliverable addresses?

Yes. Download options include filtered sets such as maximum deliverability, maximum reach, undeliverable, and all emails.

Which integrations are available?

ValidEmail connects with popular marketing, CRM, lead capture, ecommerce, and automation tools. View available integrations.

Do you remove duplicates?

Bulk job reporting can surface duplicate counts when duplicates are detected, so repeated rows are easier to clean up.
