Audit HS03 fires when this collapses without a list-size reason. How to read it, why it matters, and how to act on it. **Metrics type:** [Key Metrics](/nerve-centre/overview#metrics-types-explained) • **Category:** [Email Marketing](/nerve-centre/connectors#connectors-by-type) > Marketing-Hub send volume. Audit HS03 fires when this collapses without a list-size reason. ## At a glance > Total Marketing-Hub email send volume in the period. The headline send-cadence number; collapses without a corresponding list-size reason fire audit HS03. Pulled from `EMAIL_EVENT.SENT` events via `/marketing/v3/emails`. | | | | ----------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **What it counts** | `COUNT(distinct EMAIL_EVENT where event_type = 'SENT')` across all Marketing-Hub email sends in the window. Includes campaign blasts, A/B test variants, and workflow-triggered emails (welcome series, nurture, lifecycle). | | **HubSpot Hub scope** | Marketing Hub. Sales Hub one-to-one Sequences and Service Hub emails are excluded; they are tracked separately. | | **Definition of "sent"** | A `SENT` event fires the moment HubSpot's mail server hands the message to the recipient's MTA. Excludes pre-flight rejects (invalid syntax) but includes messages that hard-bounce post-send. | | **A/B test handling** | Both variants count. A test sent to 10,000 split 50/50 contributes 10,000 sends, not 5,000 + 5,000. | | **Workflow-triggered emails** | Included. Welcome flows, lifecycle nurture, and abandonment automations all add to this count. To split, see Workflow Enrolment Volume. | | **Sequence sends (1-to-1)** | Excluded. Sales Hub Sequence sends are tracked through `hs_email_engagement`, not `EMAIL_EVENT`. | | **Bounces** | Counted as `SENT` (HubSpot fires SENT first, then BOUNCED). Use Delivery Rate to back out clean delivery. | | **Skipped recipients** | Excluded. Contacts skipped due to suppression-list, unsubscribe, or low-engagement filtering never get a `SENT` event. | | **Currency** | n/a (count). | | **Time window** | `30D vsP` (30 days vs prior 30 days). | | **Alert trigger** | `drop >15% MoM`, drives `sentiment_key: send_volume`. Audit HS03 cross-fires when the drop has no corresponding list-size cause. | | **Roles** | owner, marketing | ## Calculation Calculated automatically from your HubSpot data. See the At a glance summary above for what the metric tracks and the worked example below for a typical reading. ## Worked example A B2B SaaS portal with 84,200 contacts running Marketing Hub Pro. The 30-day window is 14 Mar 26 to 12 Apr 26. | Source | Sends | Notes | | ------------------------------------- | ----------- | ------------------------------- | | Monthly product newsletter (4 sends) | 162,400 | 40,600 recipients × 4 sends | | Spring webinar promotion (3 emails) | 28,200 | 9,400 invited segment | | Pricing-page revisit re-engagement | 12,800 | List-based segment, single send | | Welcome workflow (5-step nurture) | 8,400 | New signups in window x 5 | | Customer onboarding workflow (3-step) | 1,650 | New customer cohort x 3 | | MQL handoff workflow (2-step) | 4,200 | MQLs created in window x 2 | | Quarterly customer-care newsletter | 4,800 | Customer-stage segment | | **Total this card** | **222,450** | | Compared with the prior 30 days (12 Feb 26 to 13 Mar 26): | Period | Sends | Delta | | --------------------------------- | ------- | ---------- | | 14 Mar 26 to 12 Apr 26 | 222,450 | +16.8% | | 12 Feb 26 to 13 Mar 26 | 190,400 | (baseline) | | Year ago (14 Mar 25 to 12 Apr 25) | 142,800 | +55.8% YoY | Five things this picture reveals: 1. **73% of sends come from two sources, the monthly newsletter (162,400) and the webinar campaign (28,200).** Workflow sends are 14,250 (6.4%). For a Marketing-Hub-mature portal the workflow share should be 25-40%; this team is over-reliant on broadcast newsletters. 2. **The 16.8% MoM growth is healthy and consistent with list growth.** Audit HS03 only fires when sends drop >15% with no list-size reason. Here the trend is up and the list is growing, no audit fires. 3. **YoY growth of 55.8% reflects scaling, not list bloat.** Total Contacts grew 38% in the same period; sends grew faster, meaning send-frequency-per-contact rose. That increases unsubscribe risk; pair with the Unsubscribe Rate card. 4. **A 30%+ MoM collapse without list shrinkage is the canary scenario.** Common causes: a workflow turned off (someone disabled the welcome flow during a redesign), the Marketing Email tier hit its monthly send limit, send-from-address was unverified after a domain change, or a List-trigger workflow broke. Audit HS03 surfaces the cause. 5. **Sequence sends (1-to-1 from sales reps) do not appear here, even though they look identical to recipients.** A sales team sending 4,000 sequence emails per month adds zero to this card. To see total outbound, sum this card with Sales Hub Sequence sends from the dedicated card. ## Sibling cards merchants should reference together Send volume on its own is a vanity metric. Pair it with these: | Card | Why pair it with Marketing Emails Sent | | ------------------------------------------------------------------------------------------------------ | -------------------------------------------------------------------------------------------------------------------------------------------- | | [Email Open Rate](/nerve-centre/kpi-cards/hubspot/email-open-rate) | The engagement view. Rising sends with falling opens is over-mailing. | | [Email Click Rate](/nerve-centre/kpi-cards/hubspot/email-click-rate) | A truer engagement signal than opens (MPP-resistant). | | [Email Unsubscribe Rate](/nerve-centre/kpi-cards/hubspot/email-unsubscribe-rate) | The cost of cadence. Sending more without earning trust pushes unsubs up; above 0.5% is the warning band. | | [Email Send Volume Trend](/nerve-centre/kpi-cards/hubspot/email-send-volume) | Daily granularity of this card. Spots cadence patterns invisible at the 30-day rollup. | | [Top Emails by Clicks](/nerve-centre/kpi-cards/hubspot/top-emails-by-clicks) | Which sends earned attention. Tells you which content to repeat. | | [Workflow Enrolment Volume](/nerve-centre/kpi-cards/hubspot/workflow-enrolments) | The workflow-driven slice. Workflow sends should grow as a share of total over time. | | [Email-Attributed Commerce Revenue](/nerve-centre/kpi-cards/hubspot/email-attributed-commerce-revenue) | The revenue payoff. Cross-check with commerce platform; if sends rose and email-attributed revenue did not, the campaigns missed. | | [Klaviyo Total Sends](/nerve-centre/kpi-cards/klaviyo/total-sends) | If both ESPs are connected (rare overlap), Klaviyo handles commerce subscribers and HubSpot handles CRM nurture. The two should not overlap. | ## Reconciling against the vendor's own dashboard **Where to look in HubSpot:** Two native views give the closest comparison: > [HubSpot → Marketing → Email → Analyze](https://app.hubspot.com/email) (Performance tab, filter to last 30 days) > [HubSpot → Reports → Analytics tools → Email analytics](https://app.hubspot.com/reports-dashboard) The Performance tab's "Sends" column summed across all emails should match this card to within a few hundred. **Why our number may legitimately differ from HubSpot's:** | Reason | Direction | Why | | ---------------------------- | ------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Portal timezone vs UTC** | Boundary days off | HubSpot's analytics screens use the portal account timezone for window boundaries; Vortex IQ uses UTC by default. A US-Pacific portal will see a 7-9 hour boundary shift, which on cadence-heavy days can move the figure 1-3%. | | **Sync lag** | Ours lower for the most recent 5-15 minutes | Marketing emails just sent may not be in our index yet; HubSpot's UI updates near-instantly. | | **Workflow-triggered sends** | Either | HubSpot's Email Performance tab can be filtered to "Marketing emails" only, which excludes workflow sends; Vortex IQ includes both. Apply the All-emails filter for the closest match. | | **A/B variant counting** | Same | Both sides count both variants. | | **Sequence sends** | Same | Excluded on both sides. | **Cross-connector reconciliation:** When a merchant runs HubSpot Marketing Hub alongside a separate ESP (Klaviyo for commerce, Mailchimp legacy), each ESP's send-volume figure is independent and they should not overlap subscribers. If they do, two compliance issues to check: | Card | Expected relationship | What causes legitimate divergence | | ------------------------------------------------------------------------------ | -------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | [Klaviyo Total Sends](/nerve-centre/kpi-cards/klaviyo/total-sends) | Should target a different audience (commerce subscribers vs CRM contacts) | Subscriber-list overlap means contacts are receiving emails from both ESPs, raising unsubscribe risk and complaint rate. Surface via Top Customers Without HubSpot Contact (inverse, those in commerce but not CRM). | | [GA4 Email channel sessions](/nerve-centre/google_analytics/ga_email_sessions) | Sessions from `medium=email` UTMs should track HubSpot send volume directionally | UTM hygiene matters; un-tagged HubSpot links land in `direct` or `referral`, not `email`. | ***
Documentation cross-reference (for agencies running multiple ESPs) Send volume is a universal ESP concept. Same number on: * [`klaviyo.klv_total_sends`](/nerve-centre/kpi-cards/klaviyo/total-sends) * [`mailchimp.mc_total_sends`](/nerve-centre/kpi-cards/mailchimp/total-sends) (when added) * [`dotdigital.dd_total_sends`](/nerve-centre/kpi-cards/dotdigital/total-sends) (when added) Send-cadence-per-active-subscriber is the cross-platform health proxy.
## Known limitations / merchant FAQs **Why is my HubSpot send count different from my Marketing dashboard?** Three usual causes: (a) timezone, HubSpot's UI uses portal timezone, Vortex IQ uses UTC. (b) Filter scope, HubSpot's Performance tab can be filtered to Marketing-emails-only and exclude workflow sends; this card includes both by default. (c) Sync lag, the most recent 15 minutes of sends may not be in our index yet. **My send count dropped 30% MoM but my list size is the same, what happened?** Audit HS03 fires precisely on this scenario. Common causes: (a) a workflow turned off (someone disabled the welcome flow during a redesign), (b) the Marketing-Hub send-quota tier was hit, (c) send-from-address was unverified after a domain change, (d) a list-trigger broke (deleted property, missing list), (e) IP-warming pause (new dedicated IP). Audit HS03 surfaces the cause within 24 hours. **Does this include Sales Hub Sequence emails?** No. Sales Hub Sequence sends are 1-to-1 outreach (mostly looks-like-Gmail emails from rep accounts) and do not flow through Marketing Hub. They are tracked separately. To see total outbound add Sequence sends from the Sales Hub card. **Why are A/B test variants both counted?** Because each variant is a real send to a real recipient. A 10,000-recipient test split 50/50 sends 10,000 emails. Counting half would understate. The HubSpot Performance tab counts the same way. **List-membership refresh lag, does it affect this?** Active list memberships are evaluated on a 15-minute schedule. If a contact joins a list at 09:50 and the list-trigger workflow runs at 10:00, the email may not fire until the 10:15 cycle. The send count for that day is correct; just lagged by up to 15 minutes. **Multi-portal aggregation, what does this show?** One card per portal. Vortex IQ does not aggregate across HubSpot portals because send-quota tiers, suppression-list state, and IP reputation are per-portal. **Today-volatility, why is this number jumpy intra-day?** Marketing-email cadence is concentrated at certain hours (most teams send 09:00 and 14:00 portal-local time). The intra-day curve is bimodal, not smooth. The 30D rollup smooths this out. **Why is my deal pipeline number different from my dashboard playbook?** This is the email-sends card, not deals. They are independent metrics. Send volume rising while pipeline is flat means email is reaching new contacts but those contacts are not yet converting; check Lead-to-MQL and MQL-to-SQL rates next. **Sequence enrolment vs send timing, what is the difference?** Workflow enrolment is when a contact joins an automation; send timing is when the message actually fires (often 1-day or 3-day-delayed steps in the sequence). This card counts the send, not the enrolment. The Workflow Enrolment Volume card counts the enrolment. *** ### Tracked live in Vortex IQ Nerve Centre *Marketing Emails Sent* is one of hundreds of KPI pulses Vortex IQ tracks across HubSpot and 70+ other ecommerce connectors.
