How to Send ZoomInfo Contacts into an Instantly Campaign with Claude Code

Connect ZoomInfo and Instantly in Deepline, describe your ICP contacts in the chat, and Claude pulls + enriches + pushes to the Instantly campaign. Deepline handles ZoomInfo's JWT rotation automatically.

00Direct answer

ZoomInfo to Instantly workflow

ZoomInfo to Instantly is a supported Deepline workflow path for Claude Code. Use it when an agent needs to run ZoomInfo, inspect the returned fields, and write the reviewed result into Instantly with run history, retries, and explicit failure states.

Best query match

“How do I connect ZoomInfo to Instantly with Claude Code?”

Source primitive

ZoomInfo returns structured fields that Deepline records with provider attribution and row-level status.

Destination primitive

Instantly receives only reviewed rows after the pilot command succeeds.

01Primitives first

This workflow moves data from ZoomInfo into Instantly with Claude Code as the orchestration layer. It is strongest when you need a repeatable, inspectable handoff with explicit auth, cost math, and recovery steps.

04Walkthrough

Step-by-step

  1. 01

    Install Deepline

    One command installs the Deepline CLI and registers a workspace. Takes about 30 seconds. You only do this once per machine.

    curl -s "https://code.deepline.com/api/v2/cli/install" | bash
    deepline auth register
  2. 02

    Connect ZoomInfo in the Deepline dashboard

    In the Deepline dashboard, click Integrations → ZoomInfo → paste your ZoomInfo API credentials (client_id + client_secret). Deepline handles the OAuth JWT flow and refreshes tokens every 55 minutes.

  3. 03

    Connect Instantly in the Deepline dashboard

    In the Deepline dashboard, click Integrations → Instantly → paste your API key from Instantly Settings → Integrations. Deepline will auto-list your active campaigns so you can pick the destination per run.

  4. 04

    Chat with Claude

    Open Claude Code and describe the workflow in plain English. Deepline handles the tool calls, waterfall routing, rate limits, auth refresh, and dedup. An example prompt for this pair:

    > From ZoomInfo, find CFOs and VP Finance roles at US SaaS companies with 500+ employees. Enrich for work email. Push into Instantly campaign "CFO Outbound" with the ZoomInfo job_title and companyName as custom variables for copy personalization.
  5. 05

    Deploy as a workflow

    Once Claude's one-off run looks right, type "Deploy this as a workflow" and tell it the schedule. Deepline wraps the exact prompt + tool chain as a recurring workflow with run history, billing, and alerting in the dashboard.

    > Deploy this as a workflow that runs every weekday morning at 8am.
05Cost math

What this costs to run

For 1,000 leads: $8.00

~0.8 credits per contact. ZoomInfo's API is the priciest of the majors but has the best senior-leader coverage in North America. Deepline's credit pricing is pay-as-you-go — see code.deepline.com/docs/pricing for current rates.

06Why Claude Code

Why do it in Claude Code

Waterfall routing by default

Deepline tries the cheapest provider first and only falls back if it misses. For ZoomInfo workflows, this means email enrichment stops at the first valid hit — you don't pay for the second and third provider unless you need to.

Deploy the exact prompt as a schedule

Once the one-off run looks right, "Deploy this as a workflow" wraps the same prompt + tool chain as a cron-scheduled workflow. Run history, per-run billing, and retry logic all live in the dashboard. No DevOps.

One place for every provider credential

ZoomInfo keys, Instantly OAuth, waterfall fallbacks (Hunter, Dropcontact, Findymail, Prospeo) — all live in the Deepline dashboard. Rotate once; every workflow picks up the new credential automatically.

What people are saying

Instantly gives me the highest reply rate by far — higher than any other sequencer I've tried with the same Apollo list.

A proper email waterfall lifts match rate to 80%+ versus 35-50% from any single provider.

Troubleshooting

ZoomInfo integration shows red in the Deepline dashboard

Cause: ZoomInfo credentials are either expired, revoked at the provider side, or the account tier doesn't expose API access.

Fix: Click the integration row in the dashboard → Test Connection. If it fails, re-paste the API key (or re-run OAuth for key-based providers). Confirm the provider account tier includes API access — most providers gate this to paid tiers.

Workflow run succeeds but 0 rows landed in the destination

Cause: The filter returned 0 matches, OR rows failed a downstream gate (email not verified, already in destination, deliverability check failed).

Fix: Open the run in the Deepline dashboard → expand the step-by-step trace. Every row's path is logged: matched/unmatched at each stage. Most frequent culprit is the email-verification gate. Loosen the filter or remove the gate in the prompt if that's the cause.

Scheduled workflow stopped firing

Cause: Either hit a provider rate-limit, ran out of Deepline credits, or the destination API returned 500s Deepline classified as permanent.

Fix: Dashboard → Workflows → Recent Runs. Failed runs show the exact error and a "Replay" button. Credits are visible top-right. Rate-limit issues auto-resume once the window resets; permanent errors need intervention.

09Reference questions

FAQ

Do I need an Anthropic API key for this?

No. You need Claude Code (the CLI/IDE). Deepline provides the tool-execution layer and credit system. Your Claude Code subscription or Anthropic API key handles the LLM calls — Deepline handles the GTM actions underneath.

How does Deepline handle dedup across runs?

Built-in. For Instantly as a destination, Deepline uses the provider-native idempotency key (email for HubSpot/Attio, External_Id for Salesforce, campaign-level dedup for Instantly/Smartlead/Lemlist). Reruns update existing records instead of creating duplicates.

Can I still use my own API keys?

Yes. Paste them in the Deepline dashboard under Integrations. Deepline uses your keys for the actual provider calls — you keep your provider contracts, billing, and rate limit allocation. Deepline's credit billing only covers the orchestration + waterfall layer.

What if my filter only matches 3 rows but the workflow says 1000?

Deepline runs exactly what you describe. The 1000 in cost-math is the reference cost per 1K rows — a 3-row run costs 3/1000 of that total. You never pay for rows that don't exist.

Can I combine this with a waterfall?

Yes. Mention it in the prompt — e.g. "If ZoomInfo doesn't return an email, fall back to Hunter → Dropcontact → Findymail." Deepline assembles the waterfall automatically and charges you only for the provider that successfully finds each row.
