Find failures, leaks and risks before they cost sales. Monitor orders, fulfilment, delivery and settlement. Improve discovery, conversion, campaigns and repeat purchase. ### From connection to verified outcome The controlled sequence every capability follows. Nothing changes a connected system without the approval step. Authorise the source. Scopes are shown before access is granted. Watch the signals against your own baselines, not universal defaults. Run checks and gather evidence specific to your store. Explain what happened, why it matters and the proposed action. You review scope, risk and reversibility before anything changes. Apply through governed connector operations. Confirm the intended result and keep the receipt. No changes are made without the configured approval policy. Read-only operations do not modify the connected system; schedules, access scopes, API usage and data handling remain governed by Vortex IQ controls. ### Monitor performance 18 performance signals. Open an outcome to see its signals and how each one alerts. Read-only operations do not modify the connected system. | Signal | Alert behaviour | What it tracks | | ----------------------------- | ----------------- | ----------------------------------------------------------------------------------- | | **Campaign Status Breakdown** | Watch only | Newsletters and broadcasts grouped by status (sent, draft, scheduled). | | **Click-to-Open Rate** | Alert band 10 / 3 | Clicks as a share of opens - engagement quality independent of open-rate inflation. | | **Conversion Rate** | Alert band 3 / 1 | Converted / sent - ties send volume to the campaign goal. | | **Email Click Rate** | Alert band 3 / 1 | Clicked / delivered - the clearest engagement signal. | | **Flow Count Summary** | Watch only | How many campaigns exist on the workspace. | | **Flow Status Breakdown** | Merchant rule | Campaigns split by state (running, draft, stopped). | | **Flows List** | Watch only | Every campaign (triggered journey) and its current state. | | **Total Sends** | Watch only | Total emails sent across campaigns and newsletters in the window. | | Signal | Alert behaviour | What it tracks | | -------------------------------------- | -------------------- | --------------------------------------------------------------------------------------------------------- | | **Abandoned-Cart Recovery Value** | Watch only | \$/30D recovered by the abandoned-cart campaign. Goes to zero if the campaign is in draft (CIO-CAMP-001). | | **Bounce Rate** | Alert band 2 / 5 | Bounced / sent. Bounce >5% trips ISP throttling. Audit CIO02 fires here. | | **Delivery Rate** | Alert band 98 / 95 | Delivered / sent. Below 95% needs attention. | | **Email Share of Total Store Revenue** | Merchant rule | Healthy DTC ranges 20-30%. Below 15% = email under-leveraged; above 40% = paid-acq atrophy risk. | | **Engagement Funnel** | Watch only | Sent -> Delivered -> Opened -> Clicked. Drop-offs expose deliverability vs content weakness. | | **Spam Complaint Rate** | Alert band 0.1 / 0.3 | Spammed / delivered. Above 0.1% Gmail starts marking sender domain. CIO03 fires. | | **Unsubscribe Rate** | Alert band 0.5 / 2 | Unsubscribed / delivered. A spike signals list fatigue or off-target content. | | Signal | Alert behaviour | What it tracks | | ----------------------------- | ------------------ | -------------------------------------------------------------------------------------------------- | | **Active Subscribers (Est.)** | Watch only | Estimated subscribed, reachable customers (total minus unsubscribed). | | **Email Open Rate** | Alert band 25 / 15 | Opened / delivered. Apple Mail Privacy inflates this - pair with click-to-open for a truer signal. | | **Segments Overview** | Merchant rule | Saved segments and their member counts. Audit CIO04 fires below 3 segments. | ### Audit risks and opportunities A fix status appears only where the action, inputs, approval, verification and recovery controls are mapped. Candidate remediations are never executable. Open a check for the detail. **Severity** critical · **Outcome** Protect revenue · **Fix status** Report only Spam complaints are the fastest way to damage sender reputation with mailbox providers; a rate this high can get future campaigns throttled or routed to spam even for recipients who never complained, which drags down deliverability for the whole list, not just the segment that complained. Vortex IQ detects and explains this; resolution is manual, with evidence and recommended steps. Reference: `EM-DEL-002` **Severity** high · **Outcome** Protect revenue · **Fix status** Report only Abandoned-cart recovery is usually the single highest-ROI automation in email: high-intent shoppers who nearly bought are contacted at exactly the right moment. Without it they are never contacted at all. Vortex IQ detects and explains this; resolution is manual, with evidence and recommended steps. Reference: `EM-FLOW-001` **Severity** high · **Outcome** Protect revenue · **Fix status** Report only More than 1 in 20 emails is bouncing. Beyond the immediate lost reach, mailbox providers watch bounce rate as a sender-reputation signal, and a rate this high risks future emails, even to good addresses, landing in spam instead of the inbox. Vortex IQ detects and explains this; resolution is manual, with evidence and recommended steps. Reference: `EM-DEL-001` **Severity** high · **Outcome** Protect revenue · **Fix status** Report only More than 1 in 20 emails is not reaching an inbox at all, whether blocked, bounced, or filtered. Every campaign, promotion or transactional email built on this list is reaching a materially smaller audience than the send count suggests. Vortex IQ detects and explains this; resolution is manual, with evidence and recommended steps. Reference: `EM-DEL-003` **Severity** medium · **Outcome** Protect revenue · **Fix status** Candidate remediation Bounced emails never reach the customer, and past roughly 5% mailbox providers treat the sender as risky, dragging down delivery of every future campaign including the ones that make money. A likely corrective operation exists, but its mapping and recovery are not yet complete, so execution is not offered. Evidence and recommended manual steps are provided. Reference: `CIO02` **Severity** medium · **Outcome** Protect revenue · **Fix status** Report only A rising unsubscribe rate shrinks the reachable audience and usually signals frequency or relevance problems; every lost subscriber removes future campaign and flow revenue. Vortex IQ detects and explains this; resolution is manual, with evidence and recommended steps. Reference: `CIO05` **Severity** medium · **Outcome** Protect revenue · **Fix status** Candidate remediation Automations that are switched off or erroring stop producing revenue silently; abandoned-cart, welcome and win-back flows are typically the highest-earning sends a store has. A likely corrective operation exists, but its mapping and recovery are not yet complete, so execution is not offered. Evidence and recommended manual steps are provided. Reference: `CIO01` **Severity** medium · **Outcome** Protect revenue · **Fix status** Report only Spam complaints are the fastest way to destroy sender reputation. Above roughly 0.1 percent, providers start routing campaigns to junk for everyone, not just complainers, cutting email revenue silently. Vortex IQ detects and explains this; resolution is manual, with evidence and recommended steps. Reference: `CIO03` **Severity** medium · **Outcome** Grow revenue · **Fix status** Candidate remediation New subscribers are at their most engaged in their first days; without a live welcome flow that window closes unconverted. A likely corrective operation exists, but its mapping and recovery are not yet complete, so execution is not offered. Evidence and recommended manual steps are provided. Reference: `EM-FLOW-002` **Severity** low · **Outcome** Grow revenue · **Fix status** Report only Broadcasting to one undifferentiated list sends the same message to buyers, prospects and lapsed customers alike, which depresses engagement and accelerates unsubscribes. Vortex IQ detects and explains this; resolution is manual, with evidence and recommended steps. Reference: `CIO04` **Severity** low · **Outcome** Protect revenue · **Fix status** Report only With fewer than 3 segments, campaigns are almost certainly going to the entire list every time, new customers and loyal repeat buyers, engaged subscribers and people who have not opened an email in a year, all treated identically. That flattens response rates and raises the same unsubscribe and spam Vortex IQ detects and explains this; resolution is manual, with evidence and recommended steps. Reference: `EM-LIST-001` **Severity** low · **Outcome** Grow revenue · **Fix status** Candidate remediation More than 3 automation flows are built but never turned on. Each one represents planned revenue, welcome series, replenishment reminders, win-back campaigns, that is sitting unused; the work to build them already happened, so the only thing standing between the store and that revenue is publishing t A likely corrective operation exists, but its mapping and recovery are not yet complete, so execution is not offered. Evidence and recommended manual steps are provided.
