Verify your VerticalResponse audience before you send

VerticalResponse contact lists can include active, bounced, and unsubscribed records in the same download, which makes it easy to re-mail addresses that should stay suppressed. Exporting a list, verifying deliverability with Bounceless, and re-importing only send-decision rows separates dead mailboxes from legitimately suppressed contacts before the next send.

How it works

[01]Download your VerticalResponse listGo to the Contacts tab, open the list you want to check from the table of contact lists, and on the Active tab click More Actions on the right side, then choose Download List. VerticalResponse delivers a CSV that includes custom fields plus bounce and unsubscribe status where recorded.
[02]Verify the CSV in BouncelessUpload the downloaded CSV to Bounceless and run a bulk verification job. Each address receives a confidence level, reason codes, and a Pre-Send Decision independent of the bounce flag stored in VerticalResponse.
[03]Download the verified resultsWhen processing completes, download the results and filter to send-decision rows. Exclude suppress-decision addresses even if VerticalResponse still lists them as active — verification may show they are undeliverable now.
[04]Re-import or update the clean contactsUse VerticalResponse list import or mass-update tooling to upload the verified send-decision file. Respect existing unsubscribe records: do not re-import addresses VerticalResponse marked unsubscribed unless you have fresh consent and a business reason to do so.

When to run it

Cleaning before a re-engagement campaignDownload the target list, verify it in Bounceless, and remove undeliverable rows before a re-engagement send so VerticalResponse bounce tracking does not spike on addresses that were already dead.
Auditing bounce and unsubscribe columnsVerticalResponse includes bounce and unsubscribe data in list downloads. Cross-check those flags against Bounceless Pre-Send Decisions to find addresses flagged active in VerticalResponse but undeliverable on verification.
Migrating off VerticalResponseTeams moving to another ESP often start with a VerticalResponse CSV export. Verify that migration file in Bounceless before uploading anywhere else so list decay does not follow you to the new platform.

Common questions

Does VerticalResponse include bounces in the CSV download?

Yes. VerticalResponse Download List help states the CSV includes contact fields plus bounce and unsubscribe information where available. Use Bounceless on the email column to get a current deliverability read, then decide whether an address should stay suppressed, be removed, or be retried based on your consent and list policy — not the stale flag alone.

Can I use the VerticalResponse API instead of Download List?

VerticalResponse documents downloadList and downloadListBackground API methods with csv delimiters for programmatic exports. This guide follows the dashboard Download List flow so marketers without API credentials can run the same verify-then-import loop Bounceless supports for other ESP CSV workflows.

Does Bounceless override VerticalResponse unsubscribe status?

No. Bounceless verifies deliverability, not consent. If VerticalResponse marks an address unsubscribed, keep it suppressed unless you have a documented re-permission path. Use verification to avoid mailing dead addresses among your opted-in contacts, not to bypass unsubscribe records.
