Open-source self-hosted cold email platform — the free alternative to Instantly, Smartlead, and Lemlist

← Talking to customers
Quickly: cold email outreach. Open-source self-hosted alternative to Instantly.

In simple English

This tool lets you run cold email campaigns from your own server. You can send multi-step sequences and track replies without paying a monthly subscription fee. It connects directly to your Gmail and Microsoft 365 accounts to send messages safely. You host everything on your own infrastructure, so your lead data stays completely private. Setup takes a few minutes using Docker, and you will need a server or a cloud hosting account.

What it is

Quickly is a self-hosted cold email platform built with Python and React. It provides email sequencing, inbox rotation, unified inbox management, and automated reply classification.

What it is good for

Solo builders, sales teams, and agencies who want to run cold outreach campaigns without paying high monthly fees for cloud services.
