Email Marketing Bot: Chrome Extension

A browser-based, multi-tab email automation tool built as a Chrome extension.

The Challenge

The desktop bot could only run one automation session at a time. The client wanted a lighter-weight, browser-native way to run multiple sending batches in parallel to increase throughput while reducing the chance of getting flagged as spam.

What We Built

A Chrome extension paired with a website where users enter recipient lists, subjects, and email bodies. Starting the automation generates a small script that users copy into the Chrome console. Opening additional Chrome windows and pasting the script in each lets multiple sending batches run at once, spreading the volume across tabs.

  • Chrome extension installed directly in the browser
  • Companion website for entering recipients, subject lines, and email bodies
  • Auto-generated console script for starting a sending batch
  • Multi-window support to run several batches in parallel
  • Batch-based sending designed to reduce spam/CAPTCHA detection risk

Where It Stands

Gave the client a way to send higher email volumes in parallel batches, reducing the risk of getting caught by spam/CAPTCHA detection.
