FAQ

Questions, answered.

Quick answers to what companies ask us most.

What is PrometheusMail?
PrometheusMail is an AI email automation platform for companies. It combines AI email drafting, a built-in CRM, and internal chat in one tool. Unlike Fyxer or Superhuman, it runs its own AI on our own infrastructure — no data goes to OpenAI or Anthropic.
Who is PrometheusMail built for?
PrometheusMail is built for companies of 5 to 200 people - from agencies and software houses to any business that lives in email. Per-company pricing (not per-seat) makes it especially cost-effective as you grow.
How is PrometheusMail different from Fyxer or Superhuman?
Fyxer and Superhuman send your emails through OpenAI for AI features. PrometheusMail runs its own AI on our own dedicated infrastructure — your client data never leaves our stack. PrometheusMail also includes CRM and internal chat, so you don’t need separate tools for HubSpot, Front, or Slack.
Does PrometheusMail use OpenAI or Anthropic?
No. PrometheusMail runs its own AI on our own dedicated infrastructure. Your emails are never sent to OpenAI, Anthropic, Google, or any third-party AI provider.
Is PrometheusMail GDPR compliant?
Yes — GDPR compliance is built into the architecture, not added as a checklist. We control the entire stack, no third-party AI providers touch your data, and a DPA (Data Processing Agreement) is available for every customer.
When can I start using PrometheusMail?
PrometheusMail launches in August 2026. The first 100 companies on the waitlist get 50% off for life. Join the waitlist on prometheusmail.com to secure early access.
What does PrometheusMail cost?
PrometheusMail is priced per company (not per seat): Starter $49/month, Pro $129/month, Business $249/month. The first 100 companies on the waitlist get 50% off for life.
How is the AI different from a chatbot?
PrometheusMail is an AI agent, not a chatbot. It reads each email against your business knowledge, past conversations, and client history, then drafts replies in your company’s voice. You choose the autonomy level: manual review, semi-auto for high-confidence replies, or full autopilot.
Which email providers does it work with?
PrometheusMail connects to Gmail, Google Workspace, Outlook, Microsoft 365, Yahoo Mail, Yandex Mail, Zoho Mail, and any standard IMAP server.
Can I cancel anytime?
Yes. One-click cancel, no hidden fees, no contracts, no phone calls. No notice period.
