The Problem

Manual outreach doesn't scale.

A student organizing committee needed 450 local businesses contacted for event sponsorship. Doing it by hand was impossible within their timeline and budget.

The Pipeline

6 steps. Fully automated.

From a raw list of businesses to qualified sponsors — without a single manual email.

Step 01
Data Import & Enrichment

Google Sheets with 450 businesses gets pulled into n8n. Each entry is enriched with industry type, website URL, and contact information from public sources.

Step 02
Company Research (AI)

Claude API analyzes each business: what they sell, who their customers are, and what connection they might have to the event. This research becomes the basis for personalization.

Step 03
Email Generation (AI)

Each email is uniquely written by Claude, referencing the business's specific products, location, and relevance to the event audience. No templates — every email is different.

Step 04
Automated Sending

Emails are sent via SMTP with proper rate limiting, SPF/DKIM authentication, and delivery tracking. Telegram bot notifies the team in real-time as each batch completes.

Step 05
Response Classification (AI)

Incoming replies are automatically classified by Claude into: positive (sponsor confirmed), negative (declined), or follow-up needed. Each is routed accordingly.

"Vielen Dank! Wir unterstützen gerne mit 200€..."Classified: POSITIVE
"Leider können wir dieses Jahr nicht..."Classified: DECLINED
"Klingt interessant, können Sie mehr Details schicken?"Classified: FOLLOW-UP
Step 06
Dashboard & Reporting

All results flow back to Google Sheets with status columns, response text, and classification. Telegram delivers a daily summary with conversion metrics.

FAQ

Common questions about outreach automation.

Every email is uniquely generated by Claude AI after researching the specific business. It references their products, location, industry, and audience — not just their name. No two emails are the same.

No. The system uses proper SPF/DKIM authentication, rate limiting, and sends from a legitimate business domain. Because every email is unique — not a duplicated template — spam filters treat them as genuine correspondence. The 17.8% response rate confirms high deliverability.

Typically 5–7 business days from kickoff to the first batch of emails going out. This includes prompt engineering, workflow building, SMTP setup, testing with a small batch, and your approval before scaling.

Yes. You can choose between review mode (every email saved for approval before sending) or auto mode (system runs autonomously after approving a test batch). Most clients start in review mode, then switch to auto after seeing the quality.

B2B outreach is covered under legitimate interest (Art. 6(1)(f) DSGVO) when relevant and proportionate. All emails include a clear opt-out mechanism, and contact data comes from publicly available business directories. Consult your legal advisor for your specific use case.

Outreach automation projects typically range from €1,500–€3,000 depending on volume and complexity. This is a one-time build cost — you own the workflow. Ongoing costs are just the AI API usage (typically €10–30/month).
