InboxFlow — Email Outreach Automation
from $5,000 setupInboxFlow achieves 40–60% better open rates than template campaigns — because every email is actually researched and written for the specific person receiving it. Claude AI reads each prospect's company website, recent news, and LinkedIn signals, then writes a unique first sentence that proves you did your homework. At scale.
Why Template Email Is Broken
Spam filters in 2025 are trained on exactly one thing: the behavior of mass-template email campaigns. They know the patterns — identical first sentences, merge-tag personalization (Hi {{first_name}}), sending domain age, volume spikes. The result is that a well-intentioned campaign hits the spam folder before the subject line is ever read.
Beyond deliverability, template email signals to the recipient that you didn't care enough to learn anything about them. The open rate tells you how many people saw the subject line. The reply rate tells you how many people thought you were worth responding to. Template campaigns average 1–3% reply rates. InboxFlow campaigns average 8–15% — because every first touch is genuinely unique.
"AI researches each prospect — LinkedIn signals, company news, website copy — and writes the kind of opening line a well-prepared rep would write after 20 minutes of research. For 500 prospects, that's 167 hours of research, done overnight."
How InboxFlow Works
A six-step pipeline from prospect list to booked meeting — fully automated after the initial sequence setup.
Prospect Import
Upload a CSV, sync from your CRM, or connect Apollo/Clay for real-time enrichment. InboxFlow accepts any prospect list format and normalizes it to a standard enrichment schema. Duplicates, invalid emails, and role-based addresses are automatically filtered before research begins.
AI Research
For each prospect, Claude AI reads their company website (about page, recent blog posts, press releases), processes recent news mentions, and analyzes available LinkedIn data. Research runs asynchronously — 500 prospects are researched overnight. The research summary for each prospect is stored and used to generate the personalized email content.
Personalized Email Generation
Claude writes a unique first-touch email for each prospect using the research summary. The opening sentence references something specific to their company — a recent hire, a product launch, a stated company priority. The rest of the email follows your approved template, but the opening line is unique per recipient. This is what drives deliverability and reply rates.
Sequence Automation
Three to five follow-up touches are scheduled automatically in n8n based on engagement signals. Touch 2 references the first email. Touch 3 adds a piece of relevant content (case study, article). Touch 4 is a brief "still relevant?" message. Touch 5 closes the sequence with a low-friction exit. Each touch is spaced by configurable intervals (typically 3–5 business days) and pauses automatically on reply.
Reply Detection
Gmail/Outlook API integration detects replies, out-of-office messages, and unsubscribe requests in real time. On positive reply, the n8n workflow triggers: sequence pause, CRM contact update, rep notification in Slack, and a meeting link send (if configured). Negative replies or unsubscribes trigger immediate suppression and CRM tagging.
Reporting Dashboard
A real-time dashboard shows open rate, click rate, reply rate, positive reply rate, and meetings booked per campaign, per sequence step, and per rep. Week-over-week trends surface which subject lines, sending times, and opening sentences are performing — feeding continuous optimization in the monthly retainer sprint.
Works With Your Existing Stack
