How to Use ZeroBounce Email Finder in Deepline
Run ZeroBounce Email Finder through Deepline, route the email verification output, and write the reviewed result into Smartlead. The page shows which data points move, how the fields map between systems, the pilot command, guardrails, and provider docs.
ZeroBounce Email Finder to Smartlead workflow
ZeroBounce Email Finder to Smartlead is a supported Deepline workflow path. Use it when an agent needs to run ZeroBounce Email Finder, inspect the returned fields, and write the reviewed result into Smartlead with run history, retries, and explicit failure states.
Use when
You need ZeroBounce email finder reviewed before it writes into Smartlead.
Source output
ZeroBounce email finder returns structured fields that Deepline records with provider attribution and row-level status.
Destination write
Smartlead receives only reviewed rows after the pilot command succeeds.
This workflow moves data from ZeroBounce into Smartlead with Deepline as the orchestration layer. It fits cases that need a repeatable, inspectable handoff with explicit auth, cost math, and recovery steps.

Quickstart setup
npm install -g deepline@latest && npm exec --yes --package=deepline@latest -- deepline setup --jsonFields agents can extract and verify
ZeroBounce source data points
- Email status
- valid, invalid, catch_all, do_not_mail, spamtrap
- Risk detail
- sub_status, free_email, role_account, disposable
- Email metadata
- email, domain, mx_found
- Validation timestamp
- validated_at, provider, run_id
Smartlead destination mapping
ZeroBounce Email address → Deepline normalized run output
email, batch_id, valid, invalid, catch_all, do_not_mail, spamtrap
Claude Code sees the email address as structured JSON, then Deepline adds provider name, action slug, run ID, retrieved timestamp, and row-level status.
Deepline normalized run output → Smartlead Campaign lead
email, name, company, campaign_id, run ID, custom fields
Custom fields should carry the exact trigger, source URL, or keyword that caused the contact to enter the campaign.
Smartlead campaign lead list → Scheduled Deepline workflow
review status, dedupe key, rollback tag, next run window
After the two-row pilot is approved, the same mapping becomes a scheduled workflow with run history, retries, and loud failures.

Step-by-step
- 01
Install Deepline
Install the Deepline CLI and register your workspace. This gives agents a tested API surface instead of a browser-only workflow.
npm install -g deepline@latest && npm exec --yes --package=deepline@latest -- deepline setup --json - 02
Connect ZeroBounce
Connect ZeroBounce in the Deepline dashboard. Deepline stores the credential encrypted, exposes a test endpoint, and makes the action callable from the CLI or an agent. Provider reference: https://deepline.com/integrations/zerobounce.
- 03
Connect Smartlead
Connect Smartlead as the destination. Use the provider page to confirm required scopes before writing data. Destination reference: https://deepline.com/integrations/smartlead.
- 04
Run a two-row pilot
Run the smallest useful pilot first. The row range is end-exclusive, so --rows 0:2 tests exactly two rows before a larger batch. Inspect email status, risk detail, email metadata plus provider attribution before writing anywhere.
deepline enrich --input leads.csv --output leads.enriched.csv --with 'result=zerobounce_email_finder:{"domain":"{{domain}}"}' - 05
Deploy the reviewed prompt
After the pilot is correct, deploy the exact prompt as a Deepline workflow. The mapping from ZeroBounce to Smartlead is preserved with run history, retries, billing visibility, and a rollback tag.
> Run ZeroBounce Email Finder on the input list, keep only usable email address, write provider attribution and status into Smartlead, and block campaign pushes until the pilot rows pass review.
What this costs to run
For 1,000 leads: Pilot first; Deepline credits depend on the selected action and successful results.
Deepline reports Deepline credits and run history. Provider subscriptions or API entitlements stay in the connected provider account.
Why run it through Deepline
The workflow stays inspectable
Deepline exposes the ZeroBounce action, runs a pilot, records the output, and writes only reviewed rows to Smartlead.
Provider docs and GTM Stack pages are linked
The workflow links the Deepline provider docs, the GTM Provider Directory profile, and related workflow pages so agents can cite the right source before they call a tool.
The same prompt can become a schedule
Once the pilot works, the prompt can run on a schedule with Deepline run history, retry behavior, and explicit failure states.
Troubleshooting
ZeroBounce returns no rows
Cause: The input filter is too narrow, credentials are missing a required scope, or the provider account tier does not expose the action.
Fix: Open the ZeroBounce integration in Deepline, run the test endpoint, and then retry the workflow on --rows 0:2 with a broader filter.
Smartlead rejects the write
Cause: The destination field names, object IDs, campaign IDs, or permissions do not match the connected workspace.
Fix: Use the Smartlead provider page to inspect the object schema, then map columns explicitly before running the full batch.
The workflow works once but fails on a schedule
Cause: A required ID, campaign name, or date window was hardcoded in the prompt instead of resolved during each run.
Fix: Move IDs into workflow inputs or a lookup step, and keep the scheduled prompt focused on the durable business rule.
FAQ
Can Deepline run ZeroBounce Email Finder directly?
Yes. Deepline exposes the ZeroBounce action as an agent-callable API and CLI step, so you can run a pilot, inspect the JSON, and then deploy the same logic as a workflow.
Should I write directly to Smartlead?
Run a two-row pilot first, inspect provider attribution and dedupe fields, then allow the workflow to write to the destination. This keeps the assertion intact without using a test hack.
How does this page help agents trust the workflow?
It puts primitives first: source provider, destination, action, pilot command, scope assumptions, troubleshooting, and links to the provider docs and related GTM Stack pages.
