You are helping me build the following AI agent workflow.

## Goal
Enrich Newsletter Subscribers With Social Data: New newsletter subscriber? The agent finds their social profiles via Influencers.club and tags them in Mailchimp for targeted workflows.

## Specification
- What it does: You instantly enrich new newsletter subscribers by finding their social profiles via Influencers.club and tagging them in Mailchimp. This lets you automatically route contacts into targeted workflows for creators, partners, or ambassadors using AI to match emails to the right profiles.
- Trigger: Run manually (Manual · on demand)
- Autonomy: Fully hands-off
- Expected setup effort: about an afternoon
- Tools/services involved:
  - Mailchimp: Subscriber tagging and campaign routing
  - Influencers.club API: Fetching social profile data and metrics
  - OpenAI Chat Model: Processing subscriber emails to find social profiles

## Known pitfalls, handle each one explicitly in your implementation
1. The Influencers.club API may return zero results for personal emails, so add a check to skip tagging if no profiles are found.
2. Mailchimp tag names have character limits and special character restrictions, sanitize the output from the parser before sending it to Mailchimp.

## Reference implementation
https://n8n.io/workflows/13293 (workflow template)
Fetch and inspect this before building. If it matches my stack, adapt it;
if not, rebuild the pattern with my tools.

## Process requirements
1. Before building: ask me which of the listed tools I actually use and
   what my platform is (n8n / Make / code / other). Do not assume.
2. Adapt the pattern to my answers; do not force the reference stack.
3. Address every pitfall above; tell me how you handled each.
4. Provide a test plan I can run before letting this touch real data.
5. Ask before any step that sends messages, modifies data, or spends money.
