Lists and segments

  • List-level organization, scoped per client folder
  • Filterable saved segments: equals, contains, contains-any, exists, in-list

Validation

  • Spam-trap checking on import, invalid addresses auto-suppressed

Find Contacts

  • Prospect search by title, company and industry via Apollo.io

  • Reconstructed even across re-imports and deletions

Outreach and campaigns

Campaigns

  • Sequence-based cold email campaigns
  • Configurable daily and hourly limits per campaign

ICP Campaigns

  • One-click setup: audience, sequence depth and generation schedule pre-wired per client
  • Auto-approves only complete, evidence-backed drafts
  • Created as a draft, sending stays a separate decision

Content Hub

  • AI-drafted sequences: 1 intro plus up to 7 distinct follow-ups
  • Each step has its own purpose, not a repeated reminder
  • Auto-stops the moment a contact replies

ICP audience-fit scoring

  • Scores whether a list contains the right buyers
  • Missing data treated as unknown, never counted against the list

A/B testing

  • Subject line, body, sender name, preview text
  • Proper statistical hold-out group

Replies and suppressions

  • Unified reply inbox across campaigns
  • Permanent and temporary suppression, plus domain-level suppression

Providers

  • Manage sending identities
  • Per-provider Microsoft/Google send-rate limits

Warm-up

  • Daily automated sends to seed inboxes
  • Manual placement logging: inbox, spam, moved from spam

Deliverability engine

Per-company send pacing

  • Prevents bursts to the same company
  • Remaining contacts queue automatically

Provider rate limiting

  • Combined Outlook- and Gmail-bound volume capped per sending identity
  • Applies across every campaign sharing that identity

Timing awareness

  • Optional recipient local-hours sending, country-level resolution
  • Weekend-aware business-hours scheduling
  • National holiday awareness across 100+ countries, warning only, never a silent skip

Sender health

  • Bounce-rate monitoring per sending identity

Domain reputation

  • Daily blocklist checks per sending domain
  • Visible history and trend, not just a cached status

AI content and protection

Grounded AI drafting

  • Live web search plus the prospect's own website, no invented facts
  • Framework-based copywriting: hook, messaging strategy, pain point, objection handling, multiple variants
  • Per-client brand guardrails: enforceable rules that can block a draft, advisory guidance for voice

Spam scoring

  • Ham / Borderline / Spam classification with visible reasons and suggested fixes
  • Bulk spam sweep across an entire sequence

Draft quality checks

  • Leaked-language, placeholder, merge-tag and missing-subject checks
  • Enforced at generation, at bulk approval, and again in a daily audit of approved-but-unsent drafts

Launch safety

  • Immediate alerts if a campaign launch is refused
  • Projects whether today's held-back backlog will clear by local midnight

Insights and reporting

Analytics

  • Campaign-level opens, clicks, replies, bounces

Intent Signals

  • Hot / Warm / Cool scoring from bot-filtered opens, verified clicks, genuine replies and recency decay
  • Heuristic and transparent, not a black box

Signal watchlist

  • News and earnings monitoring on target companies via live web search
  • Surfaced as buying-signal alerts

Client Reports

  • Shareable, code-gated public report page per client
  • Scoped to exactly that client's own campaigns

Compliance

Suppression and unsubscribe

  • Auto-suppression from bounces, unsubscribes, complaints and replies
  • Signed per-recipient unsubscribe links, no expiry

Data requests

  • Recipient erasure and opt-out requests
  • Admin-only, since acting on one is permanent

GDPR-aware tracking

  • Shows how many recipients sit under a GDPR-style regime before launch
  • Tracking can be toggled per campaign with that number in view

Billing and plans

Credit-based billing

  • Six metered services, each with its own balance and ledger: content drafting, prospect finding, list import, list validation, spam-trap checking, sending

Plans

  • Starter, Growth and Enterprise (custom)
  • Each with its own seats, send-credit allotment, Content Hub follow-up depth and prospect discovery availability

Agency and team management

Clients and workspace

  • One place for clients, team members, sending-identity assignments, settings and credits

Granular permissions

  • Access granted feature-by-feature per team member
  • Not an all-or-nothing account model

Infrastructure

  • Runs on your own infrastructure, deployed under your control
