Email Campaign

email-campaign

When To Use

Use when the user wants to assemble a targeted, verified outreach list end-to-end: discover target companies, pull emails for a domain, find a specific person's email, verify deliverability, enrich the lead for personalization, and pull company brand context. Every step is paid per-call through MPP merchants and via the SELAT Router — no API keys to manage.

Workflow

1. Install: selat skill install email-campaign
2. Run: selat skill run email-campaign --domain stripe.com --email john@stripe.com [--industry SaaS] [--firstName John] [--lastName Doe] [--company Stripe]
3. The CLI compiles each step into a selat-pay call (one MPP on Tempo payment per step), runs them in order, and prints a per-step status + summary.

Steps (in order):

• Step 1 — Fiber POST /v1/company-search — find target companies by industry and headcount.
• Step 2 — Hunter POST /hunter/domain-search — all emails found for the target domain.
• Step 3 — Hunter POST /hunter/email-finder — a specific person's email at that domain.
• Step 4 — Hunter POST /hunter/email-verifier — deliverability check for a single email.
• Step 5 — Hunter POST /hunter/email-verifier — second-pass bounce-risk check (Hunter's verdict covers catch-all domains; drop this step if one verification is enough).
• Step 6 — Apollo POST /apollo/people-enrichment — enrich the lead with contact + company details for personalization.
• Step 7 — Abstract Company Enrichment POST /abstract-company-enrichment/lookup — industry, description, size, and location for the company (no logo/color brand assets).

Inputs And Outputs

Outputs: Hunter returns email lists / verification verdicts (deliverability + bounce/catch-all); Fiber returns matching companies; Apollo returns enriched lead fields; Abstract Company Enrichment returns company firmographics (industry, description, size, location — not logos/colors).

Gotchas

• All seven steps are via the SELAT Router MPP payments — the run needs SELAT_ROUTER_URL configured and the router reachable; every step settles through the SELAT Router.
• The MPP on Tempo Hunter endpoints are POST with a JSON body ({domain}, {email}, {domain,first_name,last_name}) — not the GET/query form from the upstream Hunter docs.
• Per-step live prices (probe-verified 2026-07-10): $0.10815 + $0.01365 + $0.0084 + $0.0084 + $0.0084 + $0.0063 ≈ $0.1533 for a full manifest run; per-step maxAmount caps are ~10x each live price ($0.10–$1.00; top-level fallback $1.00) — a ceiling, not the price.
• Hunter domain-search is the most expensive step ($0.10815) — drop it if you already know your target person and only need find + verify + enrich.
• The bounce check (step 5) is a second pass through the same Hunter email-verifier endpoint as step 4 — Hunter's verdict already covers bounce risk and catch-all domains, so drop one of the two if a single verification is enough.
• Steps run independently: a later step can succeed even if an earlier one fails; always read the per-step summary.
• Every manifest step is POST with a JSON body — no query-string endpoints remain.

Validation

--chain base in the probe commands below is only the flag selat-pay requires today — a probe reads a free, chain-independent quote and never settles. A real paid run resolves the settlement chain from your funded Circle Gateway balance, not the manifest.

Probe each endpoint for a free 402 challenge (no payment sent) with --probe-only:

• selat-pay POST "https://api.fiber.ai/v1/company-search" --body '{"searchParams":{"industries":["SaaS"],"employee_count_min":50,"employee_count_max":500}}' --chain base --probe-only
• selat-pay POST "https://hunter.io/hunter/domain-search" --body '{"domain":"stripe.com"}' --chain base --probe-only
• selat-pay POST "https://hunter.io/hunter/email-finder" --body '{"domain":"stripe.com","first_name":"John","last_name":"Doe"}' --chain base --probe-only
• selat-pay POST "https://hunter.io/hunter/email-verifier" --body '{"email":"john@stripe.com"}' --chain base --probe-only
• selat-pay POST "https://hunter.mpp.paywithlocus.com/hunter/email-verifier" --body '{"email":"john@stripe.com"}' --chain base --probe-only (bounce check — same endpoint as the deliverability step)
• selat-pay POST "https://apollo.mpp.paywithlocus.com/apollo/people-enrichment" --body '{"first_name":"John","last_name":"Doe","organization_name":"Stripe"}' --chain base --probe-only
• selat-pay POST "https://abstract-company-enrichment.mpp.paywithlocus.com/abstract-company-enrichment/lookup" --body '{"domain":"stripe.com"}' --chain base --probe-only

A probe returns the merchant's 402 payment requirements without charging. A successful paid run prints status=200 and a ✓ for each step.
