Step 1
Select one email column
Highlight the rows you want to check. Blank cells, duplicate addresses, and invalid syntax are identified before the provider request.

What you get back
Valid

Each result includes a status and, when available, a reason returned by the verification provider.
Verify a working list in three steps
Step 2
Review the preview
See the unique-email count, available credit balance, and estimated credits before starting the verification.
Step 3
Choose where results go
Write status and reason columns beside the selection or separate results into Verified Emails and Emails to Review tabs.
Designed for review before sending
Prepare an outreach list
Add provider results beside the source addresses so the original rows remain easy to review.
Separate clear results from exceptions
Use new result tabs when you want valid and catch-all addresses apart from records that need attention.
Avoid repeated checks in one run
Duplicate addresses are sent to the provider once and their result is reused for matching rows.
Limits, credits, and privacy
- Select a single column with no more than 100 unique, valid-format addresses per run.
- Each unique provider-checked address may use one credit. Invalid syntax is marked without a credit, duplicates are checked once, and unknown provider results are not charged.
- Selected addresses are sent to ZeroBounce for validation; no email is sent to those addresses.
- You choose whether results are written beside the selected column or to new result sheets.
Review the privacy policy for the data flow, or contact support before checking sensitive lists.
