Plan a co-marketing campaign with a partner company

Help me plan a co-marketing campaign with a partner company. Us and the partner: [WHAT each company sells and why our audiences overlap] Audience sizes we each bring: [email list, social following, customers - approximate] Campaign idea, if any: [e.g. joint webinar, research report, integration launch, bundle offer, event] Our goal: [leads, pipeline, brand awareness in a new segment, integration adoption] Budget and resources: [WHAT we can contribute] Plan: 1. Evaluate fit: audience overlap without being competitors, brand alignment, and what each side gains. Flag imbalances (e.g. one side brings most of the audience). 2. 3 campaign concepts that give our shared audience real value, with the best one recommended. 3. Roles and responsibilities: content creation, design, promotion commitments (e.g. "2 emails + 3 social posts each"), landing page, and approvals. 4. Lead and data sharing: who owns registrants, consent language that names both companies, how leads are split and followed up, and what each side may not do with the data. 5. Timeline from kickoff to post-campaign report. 6. Shared success metrics and a debrief format. Return the campaign plan, a 1-page partnership brief to send the partner, and a checklist of terms to put in writing (data sharing, brand use, costs, approvals). Recommend checking data-sharing terms with legal or privacy colleagues.
