The "Excel-In, Excel-Out" Workflow
No webhooks, no APIs, no complex setup. Four steps from contact list to qualified leads.
Upload Your Contact List
Drop in any .xlsx or .csv file. Kolz Bulk auto-detects phone numbers, names, and custom fields — no formatting required.
Configure Your AI Agent
Pick from a library of proven sales templates — Lead Qualification, Appointment Setting, Cold B2B Intro — or write your own custom script with drag-and-drop variables.
Launch & Monitor Live
One click to start dialing. Watch call progress, completion rates, and outcomes populate in real-time on your live dashboard.
Download Enriched Results
Get your original file back — now enriched with Call Status, Lead Score (Hot/Warm/Cold), AI Summary, Call Duration, and Recording URLs. Filter for hot leads and start closing.
Everything You Need to Scale Outbound
Built for non-technical sales teams who want results, not infrastructure headaches.
Excel-In, Excel-Out
No APIs, no webhooks, no developer tools. Upload a spreadsheet of contacts, get back a spreadsheet of scored leads. Sales teams can start follow-ups immediately.
AI Call Scoring
Every call gets an AI-generated lead score (Hot/Warm/Cold), a quality indicator, and a brief conversation summary — automatically appended to your output file.
Call Recordings & Transcripts
Full audio playback and written transcripts for every single call. Complete data ownership with nothing hidden behind paywalls.
Campaign Analytics
Comprehensive post-campaign breakdown: total calls, connected calls, voicemails, outcomes, average duration, and conversion metrics.
Live Campaign Monitoring
Watch your campaign unfold in real-time. See live call progress, completion rates, and outcomes as they happen — building transparency and confidence.
30+ Language Support
Run campaigns in any language without hiring multilingual reps. The AI detects and adapts to each prospect's language automatically.
Built-in DNC Compliance
One-click Do Not Call toggles. If a prospect asks not to be contacted again, their number is immediately and securely added to your blocklist.
