About
BlitzForge AI is an AI-powered cold email engine that lives inside Gmail. Write personalised outreach emails, run multi-step follow-up campaigns, and track replies — all without leaving your inbox.
Stop spending hours writing cold emails one by one. BlitzForge generates high-converting emails from a prospect's name, company and role — with spintax variation so every email feels unique.
✦ AI EMAIL COMPOSER
Generate personalised cold emails instantly. Enter prospect details and BlitzForge writes a compelling subject line and email body — with merge tokens {{firstName}}, {{company}}, {{role}} for mass personalisation.
✦ SPINTAX VARIATION ENGINE
Use {variation1|variation2|variation3} syntax to create hundreds of unique email variants from a single template. Preview any combination before sending.
✦ SUBJECT LINE OPTIMIZER
Generate 3 scored subject line variants for any email. See predicted open rate scores so you always send the strongest subject.
✦ SPAM SCORE CHECKER
Check your email against 50+ spam trigger words and patterns before sending. Get a score and specific suggestions to improve deliverability — works offline, no API needed.
✦ MULTI-STEP FOLLOW-UP SEQUENCES
Build automated follow-up sequences with configurable day delays. BlitzForge uses chrome.alarms to check every 30 minutes and reminds you when follow-ups are due.
✦ CAMPAIGN DASHBOARD
Track every campaign: total sent, replies received, reply rate. See which sequences are performing and pause or resume any campaign instantly.
✦ CONTACT LIST MANAGER
Paste a CSV with email, firstName, company, role columns. BlitzForge merges your contact data into every email automatically.
