The Indie Founder B2B Cold Email Infrastructure Playbook

Build a deliverable, personalised cold email system that runs itself

Cold email fails for solopreneurs because of three invisible problems: poor deliverability, generic copy, and no follow-up discipline. This playbook fixes all three by layering AI-written personalised outreach, deliverability auditing, and automated follow-up persistence into one lean system. Built for B2B indie founders who need meetings booked without hiring an SDR or paying for enterprise sales tooling.

Goal

Build a cold email system with strong deliverability, personalised copy, and automated follow-up that books meetings without manual effort

Who this is for

B2B solopreneurs and indie founders doing outbound sales without a sales team

$30–$100/mo~120 min setup

How to set it up

1

Audit and fix your sending domain deliverability

Run your sending domain through Hello Inbox to identify SPF, DKIM, DMARC, and reputation issues. Fix all flagged problems before sending a single cold email to protect your domain score.

2

Research and qualify your prospect list

Feed your target prospect LinkedIn URLs into Lead Qualifier. Export a list with AI-written personalised opening lines and qualification scores for each contact.

3

Write your cold email sequences

Use Copy.ai to generate a 4-step cold email sequence for each ICP segment. Write three subject line variants per email and personalise the first line using your Lead Qualifier output.

4

Connect your email sending infrastructure

Wire your sequences to GoodSender's email API for sending. Configure your domain authentication within GoodSender to ensure maximum deliverability on outbound sends.

5

Activate automated follow-up persistence

Set up Persist to monitor each prospect and trigger follow-up touchpoints automatically across email until a reply is received. Configure stop conditions for bounces and out-of-office replies.
