The 5-tool problem

Building an outbound campaign manually looks like this:

  1. Apollo or LinkedIn Sales Nav to build the list
  2. Hunter or Prospeo to find emails
  3. ZeroBounce or NeverBounce to verify
  4. ChatGPT or Claude to write personalized lines
  5. Instantly or Lemlist to send

Each tool has its own login, billing model, and export format. A 200-contact campaign takes 2-3 hours of tab-switching.

How to build a campaign in one prompt

Step 1: Describe your ICP

Tell Claude Code

Find 50 VPs of Engineering at Series B US SaaS companies with 100-500 employees. Enrich via waterfall for verified emails. Generate a personalized first line for each. Push to my Instantly campaign 'Eng Leaders Q2'. Start with 5 as a pilot.

Claude Code reads the Deepline campaign builder skill and runs:

deepline enrich --input icp-search.csv --output campaign.csv \
  --with 'contacts=apollo_org_search:{"person_titles":["VP Engineering"],"num_employees_ranges":["100-500"]}' \
  --with-waterfall email \
  --with 'verify=leadmagic_email_validation:{"email":"{{email}}"}' \
  --with 'personalize=deeplineagent:{"prompt":"Write a 15-word personalized opener for {{first_name}} at {{company}}"}' \
  --rows 0:4

Step 2: Review the pilot

Deepline runs 5 contacts first. You see:

  • Each contact with verified email
  • The personalized first line
  • Credits used
Tell Claude Code
Looks good. Run the full list and push to Instantly.

Step 3: Scale to full list

Claude Code continues with the full run and sequences:

deepline enrich --input icp-search.csv --output campaign.csv \
  --with 'contacts=apollo_org_search:...' \
  --with-waterfall email \
  --with 'verify=leadmagic_email_validation:...' \
  --with 'personalize=deeplineagent:...'

deepline enrich --input campaign.csv \
  --with '{"alias":"push","tool":"instantly_add_to_campaign","payload":{"campaign_id":"eng-leaders-q2","leads":[{"email":"{{email}}","first_name":"{{first_name}}","last_name":"{{last_name}}"}]}}'

Results land in your sequencer ready to send.

Tell Claude Code
Deploy this as a workflow that runs every Monday at 8am.

Claude Code applies the workflow definition:

deepline workflows apply --payload '{"name":"eng-leaders-campaign","trigger":{"type":"cron","schedule":"0 8 * * MON"},"steps":[/* search + enrich + personalize + push */]}'
# Configure recurring runs and notifications via the dashboard at /workflows

Fresh leads, fresh personalization, every week. Run history in the dashboard.
