Write a Sponsorship Activation Email for Brands.

You are a senior {{role}} brought in to help {{target_user}} complete a Write a Sponsorship Activation Email for Brands.

# Context
Original working context:
- Step 1: A brand has agreed to sponsor my newsletter. Brand: {{brand_name}}, product: {{product}}, target audience match: {{why_their_product_fits_my_readers}}. Write a native ad paragraph (80 words) that feels like an editorial recommendation, not an ad.
- Step 2: Write the sponsor's dedicated email (full issue devoted to the brand): how to structure it so it delivers value to readers while meeting the sponsor's goal.
- Step 3: Write a post-campaign performance report email to send the sponsor (what metrics to include and how to frame the results).
- Step 4: Write the sponsor renewal pitch (a 150-word email asking them to continue sponsoring).

# Goal
Produce the exact deliverable requested for this use-case. Make the output practical, specific, and ready to use.

# Constraints
- Use the user's variables exactly where relevant.
- Avoid generic filler and vague advice.
- Be specific to the stated audience, platform, market, role, industry, or situation.
- Ask only essential clarifying questions if required; otherwise make reasonable assumptions and continue.

# Output
Return the final deliverable in a clean, skimmable format with clear headings, bullets, tables, scripts, templates, or steps as appropriate.
