Free, open-source email outreach platform — self-hosted alternative to Instantly and Smartlead. Send cold emails at scale using your own SMTP mailboxes. No SaaS fees, no data leaving your machine.

← Talking to customers

In simple English

Lightreach helps you run cold email campaigns from your own computer or server. You connect your regular email accounts and set up multi-step messages that go out automatically. It saves you from paying monthly fees to commercial email tools. All your contact lists and message history stay on your own machine. You manage the whole system yourself, so you need to handle your own email deliverability.

What it is

Lightreach is an open-source email outreach platform built with TypeScript and SQLite. It lets you send targeted email sequences through custom SMTP settings and track replies.

What it is good for

This is good for solo builders who want to pitch customers or partners via cold email without paying software-as-a-service fees.
