• Tone slider (formal / consultative / casual)
• A/B variant generator + multi-language auto-detect
• Workflow-action surface for sequence integration

Replaces Lavender, Smartwriter.ai

Multi-step cadences with conditional branching on open / click / reply / no-action. A pure state machine on a durable job queue makes it deterministic, replayable, and crash-safe — writing to native HubSpot engagements.

• N-step cadences with per-step delay + time-zone awareness
• Conditional branching on open, click, reply, no-action
• Send-time optimization per recipient (AI picks best hour)
• Persona-based branching + per-step variant testing

Replaces Outreach, Salesloft, Lemlist

SMTP-level pre-send validation of every address before it leaves the sequence engine, via your connected verification provider. A 30-day cache prevents repeat verifications burning credits.

• BYOK NeverBounce, Kickbox, or ZeroBounce
• MX validation, role-account detection, greylisting handling
• Verify-on-add for every new HubSpot contact
• Per-provider success-rate dashboard

Replaces NeverBounce, ZeroBounce

Generates subject variants with AI and runs them against real recipients. A two-proportion z-test auto-promotes the winner once it clears significance — no manual analysis or spreadsheet math.

• AI-generated subject variants (3–10 per call)
• Two-proportion z-test winner detection
• Multivariate testing (subject + preview + send time)
• Holm-Bonferroni adjustment for multi-variant tests

Replaces Mixmax A/B, Litmus

Classifies every reply into 12 sentiment + intent categories and routes the sequence accordingly. Replies never need to be read for the engine to make a sensible next-step decision.

• 12-category sentiment + intent classification
• Auto-suppress on unsubscribe-request and hostile labels
• Auto-stop on interested / not-interested
• Auto-forward to a coworker on wrong-person

Replaces Drift Reply, Outreach sentiment

Cross-sequence, cross-channel suppression. One unsubscribe stops every active enrollment and prevents future sends — even from sequences the contact was never in. Includes RFC 8058 one-click headers.

• One-click cross-sequence suppression
• RFC 8058 List-Unsubscribe header injection
• Syncs with HubSpot native suppression list
• Per-domain unsubscribe-rate alerts + full audit trail

Replaces SendGrid suppression, manual list scrubbing

Adds LinkedIn connect + message steps to any sequence. Each step files a HubSpot task with a deep-link and an AI-drafted message — the rep clicks send and the sequence advances automatically, within LinkedIn ToS.

• Connect-request + message steps with personalized notes
• Files a HubSpot task with a deep-link to the right page
• Per-step delay randomization so cadences look human
• Cross-channel attribution back to the sequence

Replaces Outreach + Sales Navigator, Octopus CRM, Dripify

Rotates outbound sends across multiple inboxes with per-inbox daily limits and lowest-volume-first selection. Includes a warmup ramp and per-domain spread to protect sender reputation.

• Warmup ramp schedule for new inboxes
• Per-recipient-domain spread enforcement
• Deliverability-aware throttle that slows on rising bounce rates

Replaces Lemwarm, Smartlead

• 20+ real-time blocklist (RBL) crosschecks
