Build a verified contact list for a cold email campaign

<context>
I need to build a verified contact list for an outbound cold email campaign. I want the right people at the right companies — verified emails, current titles, no bounces, no contacts who have left. I also want to know before sending whether anyone on the list has been contacted before.

My campaign:
- Campaign goal: [e.g. "cold email to VP RevOps at mid-market SaaS for Q3 pipeline"]
- Target persona: [e.g. "VP of Revenue Operations, Head of Sales Operations"]
- Target company criteria: [INDUSTRY / SIZE / GEOGRAPHY / FUNDING STAGE]
- Number of contacts needed: [e.g. "100" / "as many as possible"]
- Email sending domain: [YOUR DOMAIN — for prior contact check]
- Any accounts to exclude: [e.g. "existing customers, current pipeline, competitor accounts"]
- Sequence tool: [e.g. "Outreach / Salesloft / Gmail" — or "return as CSV"]
</context>

<task>
1. Use Lusha to find and verify contacts matching the target persona and company criteria:
   - Current verified title — must match the target persona
   - Verified work email with confidence grade (A or B only — exclude C and D grades)
   - Still at the company — no departed contacts
   - Company: headcount, industry, funding stage, HQ — must match stated criteria
   - Exclude any account on the exclusion list

2. Check Lusha's signals layer per account:
   - Any buying signal in the last 30 days: funding, exec hire, headcount surge
   - Flag signal-positive contacts for priority send — Wave 1

3. Check Gmail for any prior outreach to each contact or their company domain:
   - Has anyone from the team emailed this contact or company before?
   - If yes: when, what was discussed, did the contact reply?
   - Flag warm contacts (prior reply) separately from cold contacts (no prior contact)

4. Build the verified contact list with three send waves:
   - Wave 1 — signal positive: contacts at accounts with a live buying signal in the last 30 days
   - Wave 2 — cold, no prior contact: verified contacts, ICP match, no signal
   - Wave 3 — warm re-engagement: prior contact exists — needs a different first line

5. Return:
   - Full verified contact list: name, verified title, company, email grade, signal, prior contact flag, wave
   - Wave breakdown: X Wave 1, X Wave 2, X Wave 3
   - Any contact excluded due to C/D email grade — flag for manual review
   - Summary: X verified contacts ready to send, X excluded, X warm re-engagement
</task>

<constraints>
- Only A or B email confidence grades. C and D grades risk bounces.
- Wave 3 contacts must not receive the same first line as Wave 1 or 2 — flag for separate copy.
- Exclusion list applied before any output.
- Prior contact history mandatory on every Wave 3 contact.
</constraints>

The situation: A growth marketer needs 8 verified contacts for a Q3 cold email campaign — VP RevOps and Head of Sales Operations at mid-market B2B SaaS companies in the US, 200–600 employees. Existing customers and pipeline excluded.

Verified contact list — Q3 RevOps cold email campaign

Wave breakdown

Wave 1 — send first (signal positive) · 2 contacts R.V. at Crestline Software — hiring surge, open window now P.N. at Falcrest Tech — Series A closed 9 days ago, peak intent window

Wave 2 — cold send · 5 contacts M.L., P.O., J.A., S.P. — verified, ICP match, no signal, no prior contact

Wave 3 — warm re-engagement · 1 contact — separate copy required T.K. at Dunmore Analytics — pricing thread 54 days ago, no reply received. First line must reference the prior conversation, not open cold.

Excluded · 1 contact C.N. at Elmont Systems — email grade C, bounce risk. Flag for manual verification before including.

Summary: 7 verified contacts ready · 3 waves · 1 excluded for manual review
