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

AI content and protection

Grounded AI drafting

Live web search plus the prospect's own website, no invented facts

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

Sales follow-up

Replied leads

Central list of contacts who replied, with first reply date and client on every lead
Promoted from Contacts by a person, never auto-created from a positive-looking reply

Reply attribution

Counts emails actually delivered before the first reply, bucketed as 1st, 2nd, 3rd, 4th, 5th or later
Attribution by delivery timing, not reply-thread parsing
Replies predating send logging are excluded and labeled, never estimated

Follow-up performance

Average emails to a reply, average days to a reply, longest sequence that still replied
Count and share of replies earned by follow-ups rather than the first email
Computed from the account's own delivery log, no benchmarks or targets

Lead reply journey

Emails sent and days elapsed before each reply
The door-opener: subject line of the last email delivered before the reply

Post-reply due diligence

The prospect's replies shown in plain text beside the capture form
Structured capture across requirement, pain point, current process, use case, volume, decision maker, stakeholders, decision process, timeline, budget fit and trigger event
Status computed from what is recorded, not settable by hand

Qualification

0-100 completeness score, weighted per field, computed on read and never stored
Measures captured information only, never buying intent, never sets a temperature
Unqualified / Qualifying / Qualified / Disqualified, always set by a person
Manual sales read kept separate from computed engagement temperature

Next actions and meetings

Concrete next action with quick date picks, flags for missing and overdue actions
Overdue counting stops once a lead is won, lost or disqualified
Meeting status and date per lead, with scheduled and completed counts
A named owner per lead's follow-up

Pipeline and dashboard

One stage list from Replied through Won, Lost and Disqualified, editable inline
Counts of replied, incomplete, overdue, unactioned, qualified, meetings and opportunities
Per-client filtering with counts recomputed, count cards act as filters, free-text search

Sales access

Sales preset in guided member setup: leads, lead follow-up and replies only
Every list, count and stat scoped server-side to granted clients, gates enforced at the API

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
