Overview

CMass brings AI-powered email campaigns directly into Gmail — no extra tools, no new dashboard, no Claude account needed.

✦ AI PERSONALIZATION POWERED BY CLAUDE
Claude AI reads your contact data — name, company, role, any custom field — and writes a unique, natural-sounding personalized line for every recipient. Preview exactly what each contact will receive before you send. No Anthropic account or API key required.

📊 GOOGLE SHEETS & CSV IMPORT
Import from a Google Sheet directly from your Drive, or upload a CSV. Every column becomes an available merge tag. Duplicate detection, bounce suppression, and unsubscribe filtering happen automatically.

📬 AUTOMATED FOLLOW-UP SEQUENCES
Set up to 3 follow-up stages with custom delays and conditions. When a recipient replies, CMass detects it via Gmail and stops the sequence for that contact automatically.

📈 REAL-TIME CAMPAIGN ANALYTICS
See opens, clicks, replies, bounces, and unsubscribe rates as they come in. Per-recipient detail shows exactly who opened, when, and what they clicked.

🛡️ DELIVERABILITY TOOLS BUILT IN
One-click unsubscribe link on every email (CAN-SPAM compliant). Bounce tracking and suppression. Sending limits that respect Gmail's daily quotas.

PLANS
Free — 50 emails/day, unlimited campaigns, merge tags, follow-ups, analytics.
Pro ($29/month) — 2,000 emails/day, AI personalization, priority support.
