email-infra-campaign-buildinglisted

Build cold-email campaigns and route by ESP and SEG. Use for campaign setup, the Lead-ESP by sending-vendor decision matrix (ESP matching is dead as a fixed rule), profiling a lead list by recipient ESP with the dns-auth-audit playbook in --esp-mix mode, isolating SEG leads onto dedicated domains, and the launch gate. Triggers on build campaign, ESP matching, provider matching, ESP mix, profile the lead list, what ESP are these leads on, SEG, Mimecast, Proofpoint, Barracuda, campaign routing, sending-vendor matrix. Do NOT use for writing copy or sequences (use gt-cold-email) or reading the dashboard (use the dashboard-reading sub-skill).

# Campaign Building & ESP/SEG Routing · [GTM Engineer] > **Reads:** `{SKILL_BASE}/resources/reference.md` §1, §2, §7, §8 · **Related:** dashboard-reading, bounce-audit · gt-list-building. > 🔒 **Read-only area.** The campaign build and the routing are done from the **email infra management system**, not by hand in the sequencer. Use this sub-skill to decide *what* the campaign and routing should be, read the live config to check it, and report the gap. Do not edit a campaign or a routing rule in Instantly / EmailBison / Smartlead / Lemlist directly — that creates a second source of truth. The `--esp-mix` profiling below is read-only and safe to run. How to build a campaign that routes to the right inboxes and gets optimized from data, not from a 2024 rule of thumb. Numbers and taxonomy live in `{SKILL_BASE}/resources/reference.md` §1, §2, §8. You are not A/B-testing copy. You are reading a **matrix of already-segmented sends** and pushing volume toward what works. The winning combination is `lead list × sending vendor/ESP × recipient ESP × SEG`, and it's on the dashboard. --- ### Determining the recipient ESP mix on a lead list **Fastest path — run the playbook, no Clay credits:** ```bash cd {SKILL_BASE}/playbooks/dns-auth-audit/scripts uv run execute.py --esp-mix --file lead_domains.txt --csv acme_esp_mix.csv ``` Queries MX directly and prints the distribution, the SEG share, and a `no-email` count (domains with no MX at all — guaranteed hard bounces, strip them befo
