An r/coldemail post: first-time campaign for a hyper-niched local SEO/AEO agency. This walks the recipe for vertical-specific outbound.

Prerequisites

  • Vertical chosen
  • Sender platform at entry tier
  • Scavio API key
  • Vertical opener bank

Walkthrough

Step 1: Pick the vertical

Specific enough that one opener template per sub-niche works.

Text
// Vertical: 'small-team B2B SaaS, $1M-$10M ARR, post-Series-A'.

Step 2: Build the list

Apollo / Instantly lead-gen / scraped + verified.

Text
// Filter: industry='SaaS' AND headcount=10-50 AND funding_stage='Series A'.

Step 3: Per prospect: Scavio research

Site latest news + AI Overview + Reddit signal.

Text
// scavio.search('site:prospect-domain.com 2026'); scavio.search('{name} 2026', include_ai_overview=True); scavio.search('reddit r/SaaS {name}')

Step 4: LLM-generated opener referencing one specific detail

1-2 sentences.

Text
// LLM: 'Given research [...], write 1 opener line referencing one specific recent detail.'

Step 5: Vertical-specific opener bank as fallback

When research is thin.

Text
// Bank: 'For Series-A B2B SaaS teams scaling outbound, [...]'

Step 6: Send sequence: 1 opener + 2 follow-ups

Daily cap 30/sender.

Text
// Smartlead/Instantly sequence with daily cap.

Step 7: Measure quality not volume

First 200 sends → reply rate, reply quality.

Text
// Quality > volume in niche outbound.

Python Example

Python
# Per prospect: ~$0.01-0.02 in research.

JavaScript Example

JavaScript
// Same shape in Node.

Expected Output

JSON
Disciplined vertical cold email program with hyper-niched openers and quality-first measurement.
