Verify an email list from a CSV file

Bring your own list.

Not on a supported CRM yet? Upload a CSV export from any tool and BounceIQ returns the same list with a verification result on every row, using the engine behind our CRM integrations.

Why CSV / Manual Upload

The same verification engine, wherever your contacts live

Native, not bolted on

Verification happens where your CSV / Manual Upload contacts already are — no separate dashboard to check.

Real-time checks

Catch invalid, risky, and spam-trap addresses the moment they enter CSV / Manual Upload, not after they've cost you deliverability.

GDPR-aware handling

Built for teams that care how contact data is handled, not just whether it bounces.

How BounceIQ for CSV uploads works

Step 1

Upload your CSV

Drop in an export from any CRM, ESP or spreadsheet. BounceIQ finds the email column and previews the row count before you commit.

Step 2

Confirm your email

We send a confirmation link to the address you give us, so results only go to the person who uploaded the list.

Step 3

Pay for the list

One-off payment by card through Stripe, priced on the number of addresses. No subscription.

Step 4

Download results

Each row gets a status, reason and, where relevant, a suggested correction. Download the results as CSV from a private, signed link.

Under the hood

Architecture and data handling

Results pages and downloads use signed URLs that only work for the purchaser.
Checks cover syntax, domain and MX records, mailbox existence, disposable and role-based domains, catch-all behaviour and typo detection.
Card payments are handled by Stripe; BounceIQ never sees card numbers.
Same verification engine as the HubSpot, Mailchimp and Salesforce integrations, so results are consistent if you connect a CRM later.
