The client operating system built for marketing agencies.
Stop juggling Slack, Gmail, HubSpot, Notion, and Asana. PrometheusMail combines AI email, built-in CRM, and team chat into one platform — designed for teams that live in client inboxes.
Marketing agencies drown in client emails.
Tool chaos
Your team switches between 5 tools just to respond to one client. Gmail for emails, Slack for team chat, HubSpot for CRM, Asana for projects, Notion for notes. Context gets lost in every handoff.
Response time kills retention
Clients expect replies in hours, not days. But your team spends 3 hours daily on email triage — leaving no time for actual creative work. Slow responses = lost contracts.
Burning $1,200/month on tools
Front ($59/user), HubSpot ($50-800/mo), Slack ($7.25/user), Notion ($10/user), Asana ($10.99/user). For a 10-person agency, that’s $800–1,500 monthly — for tools that don’t talk to each other.
One platform. Three superpowers.
AI handles routine emails
Status updates, revision requests, invoice questions — PrometheusMail’s AI reads every email, understands context from past conversations, and drafts replies in your team’s voice.
Client-specific context
Every client has their own knowledge base. AI knows their brand voice, past campaigns, preferred response style. Treat clients like individuals, at scale.
Team chat tied to clients
Every channel ties to a client, project, or department. Discuss emails right next to the email thread. No more copying links from Gmail to Slack.
Replaces 5 tools
Email + AI + CRM + team chat + project context in one platform. $129/month replaces $800–1,500 in separate tools.
Here’s how marketing agencies use it.
Monday morning triage
Sarah runs a 12-person digital agency. Every Monday she used to spend 2 hours going through weekend emails — status updates, invoice questions, client feedback. With PrometheusMail, AI pre-categorizes all 47 weekend emails. 34 routine ones already have drafted responses, 13 important ones are flagged with context. Sarah’s Monday triage: 15 minutes instead of 2 hours.
New account manager onboarding
When a new AM joins your agency, they need weeks to understand client history. With PrometheusMail, they see every client’s complete history in one view — all past emails and decisions, active projects and status, client personality and preferences. AI can answer “how did we handle this last time?” in seconds.
Weekend client emergency
Client emails at 9pm Saturday with an urgent question. Your team is offline. With PrometheusMail autopilot, AI reads the email, understands it’s urgent, drafts a response with accurate info from your knowledge base. If confidence <90%, it escalates to on-call. Client gets a reply in 3 minutes, not Monday.
