Monitor email revenue and deliverability for Customer.io (API), catch broken automations early, and keep lifecycle marketing accountable to store outcomes. 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.

Signals with an alert band can raise Nerve Centre alerts; every signal supports a merchant-configured watcher. | Signal | Outcome | Alert behaviour | What it tracks | | -------------------------------------- | --------------- | -------------------- | --------------------------------------------------------------------------------------------------------- | | **Abandoned-Cart Recovery Value** | Protect revenue | Watch only | \$/30D recovered by the abandoned-cart campaign. Goes to zero if the campaign is in draft (CIO-CAMP-001). | | **Email Share of Total Store Revenue** | Protect revenue | Merchant rule | Healthy DTC ranges 20-30%. Below 15% = email under-leveraged; above 40% = paid-acq atrophy risk. | | **Active Subscribers (Est.)** | Run operations | Watch only | Estimated subscribed, reachable customers (total minus unsubscribed). | | **Bounce Rate** | Protect revenue | Alert band 2 / 5 | Bounced / sent. Bounce >5% trips ISP throttling. Audit CIO02 fires here. | | **Campaign Status Breakdown** | Grow revenue | Watch only | Newsletters and broadcasts grouped by status (sent, draft, scheduled). | | **Click-to-Open Rate** | Grow revenue | Alert band 10 / 3 | Clicks as a share of opens - engagement quality independent of open-rate inflation. | | **Conversion Rate** | Grow revenue | Alert band 3 / 1 | Converted / sent - ties send volume to the campaign goal. | | **Delivery Rate** | Protect revenue | Alert band 98 / 95 | Delivered / sent. Below 95% needs attention. | | **Email Click Rate** | Grow revenue | Alert band 3 / 1 | Clicked / delivered - the clearest engagement signal. | | **Email Open Rate** | Run operations | Alert band 25 / 15 | Opened / delivered. Apple Mail Privacy inflates this - pair with click-to-open for a truer signal. | | **Engagement Funnel** | Protect revenue | Watch only | Sent -> Delivered -> Opened -> Clicked. Drop-offs expose deliverability vs content weakness. | | **Flow Count Summary** | Grow revenue | Watch only | How many campaigns exist on the workspace. | | **Flow Status Breakdown** | Grow revenue | Merchant rule | Campaigns split by state (running, draft, stopped). | | **Flows List** | Grow revenue | Watch only | Every campaign (triggered journey) and its current state. | | **Segments Overview** | Run operations | Merchant rule | Saved segments and their member counts. Audit CIO04 fires below 3 segments. | | **Spam Complaint Rate** | Protect revenue | Alert band 0.1 / 0.3 | Spammed / delivered. Above 0.1% Gmail starts marking sender domain. CIO03 fires. | | **Total Sends** | Grow revenue | Watch only | Total emails sent across campaigns and newsletters in the window. | | **Unsubscribe Rate** | Protect revenue | Alert band 0.5 / 2 | Unsubscribed / delivered. A spike signals list fatigue or off-target content. | ## 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. | Check | Severity | Outcome | Why it matters | Fix status | | -------------------------------------------------- | -------- | --------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------- | | **Spam complaint rate > 0.1%** | critical | Protect revenue | 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 co | Report only | | **Abandoned-cart flow not live** | high | Protect revenue | 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 con | Report only | | **Bounce rate > 5%** | high | Protect revenue | 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 go | Report only | | **Delivery rate \< 95%** | high | Protect revenue | 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 | Report only | | **Email Bounce Rate** | medium | Protect revenue | 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. | Candidate remediation | | **High Unsubscribe Rate** | medium | Protect revenue | A rising unsubscribe rate shrinks the reachable audience and usually signals frequency or relevance problems; every lost subscriber removes future campaign and flow revenue. | Report only | | **Inactive Campaigns** | medium | Protect revenue | 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. | Candidate remediation | | **Spam Complaint Rate** | medium | Protect revenue | 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 reven | Report only | | **Welcome flow not live** | medium | Grow revenue | New subscribers are at their most engaged in their first days; without a live welcome flow that window closes unconverted. | Candidate remediation | | **Limited Segmentation** | low | Grow revenue | Broadcasting to one undifferentiated list sends the same message to buyers, prospects and lapsed customers alike, which depresses engagement and accelerates unsubscribes. | Report only | | **Limited segmentation , fewer than 3 segments** | low | Protect revenue | 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 e | Report only | | **Too many draft flows (> 3) , launch tech debt** | low | Grow revenue | 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 | Candidate remediation | ### Build your own automated fixes 12 checks report findings on Customer.io (API) today.
