Product Roadmap

What we've shipped and what's next. Updated as we build.

April 2026

Google & Outlook Mailboxes

Planned

Native OAuth-based connection to Google Workspace and Microsoft 365 mailboxes. No third-party relay needed.

SMTP/IMAP Support

Planned

Connect any mailbox via raw SMTP/IMAP credentials. Useful for custom domains and self-hosted mail servers.

Lemlist Integration

Planned

Webhook-based integration with Lemlist. Replies flow into Underfive automatically on new lead response.

Woodpecker Integration

Planned

Native Woodpecker connector. Auto-configures webhooks on API key entry — same flow as SmartLead/Instantly.

Apollo, Snov.io, Hunter

Planned

Expanding outbound tool coverage. Same API-key-in, webhook-out pattern. Drop-in setup.

January 2026

Multi-Calendar per Agent

Completed

Bind multiple Google Calendar or Outlook calendars to a single inbox agent. Checks availability across all before proposing a slot.

December 2025

Leads Table

Completed

Sortable, filterable table of all leads across workspaces. Shows classification, reply count, and meeting status at a glance.

MasterInbox

Completed

Unified thread view across all connected tools and senders. One place to read every conversation your agents are handling.

November 2025

Inbox Agent Creation Revamp

Completed

Rebuilt the agent setup flow from scratch. Fewer steps, better defaults, knowledge base upload baked in.

Super Inbox Agent

Completed

One agent handles your entire workspace — no trigger keywords required. Classifies intent, replies, and books across all senders.

REST API for agents, leads, threads, and analytics. Authenticate with workspace-scoped API keys. Full docs at /docs.

Automated Follow-ups

Completed

If a lead goes quiet, the agent sends a follow-up after a configurable delay. Keeps threads alive without manual intervention.

September 2025

Heyreach Integration

Completed

LinkedIn outreach via Heyreach. Webhook fires on new reply, agent processes and responds through the platform.

August 2025

Email Bison Integration

First cold email platform integration. API key + auto-webhook setup. Replies ingested and classified in real time.

Slack Notifications

Real-time Slack alerts when agents reply, book meetings, or flag leads that need human review.
