Cold email is broken.
Sending is the easy part.

Writing takes forever

You spend 3 hours crafting 40 "personalized" emails that still sound generic. AI does it in seconds, per person.

🕐

Follow-ups never happen

Day 3 follow-up? Day 7 check-in? You have a job. Loopback never misses a sequence step.

🔍

Prospecting is a second job

You have to find targets, verify emails, build lists. Loopback does it continuously, every morning.

One agent. The full loop.

01

You define the ICP

Describe your ideal customer — industry, company size, role, pain point. Loopback builds a targeting profile and saves it.

02

Loopback finds targets

It scrapes LinkedIn, enriches with company data, and verifies email addresses. New prospects added every morning.

03

AI writes personalized email

For each target, Loopback reads their LinkedIn, company blog, and recent posts — then writes an email that sounds human and specific.

04

Sends, follows up, reports

Email goes out through your connected inbox. Follow-ups trigger automatically. You get a daily report of opens, replies, and meetings booked.

What you get out of the box

AI Personalization Engine

Reads LinkedIn, company pages, and recent news to write each email from scratch. No templates. No merge fields. Just real writing.

Automated Prospect Discovery

New targets added daily from LinkedIn and enrichment APIs. Your pipeline never goes stale.

Multi-Step Sequences

Set it and forget it. Loopback handles day 1, day 3, day 7, day 14 — and every variation you configure.

Email Warmup & Deliverability

Integrated warmup so your domain stays healthy. Loopback rotates sending patterns to maximize inbox rate.

Daily Digest Reports

Every morning: opens, clicks, replies, meetings, unsubscribes. Clear numbers. No guessing.

CRM Integration

Replies and contacts auto-enrich into your CRM. Loop everything into your existing workflow.

Stop sending cold email.
Start delegating it.

Loopback is the SDR you don't have to hire, manage, or motivate. It works every day, reports every morning, and never burns out.

"We booked 12 meetings in 30 days without sending a single email ourselves."
