You can't improve what you can't see
Without per-step breakdowns you have no idea which email converts and which kills momentum. Every rewrite is a guess. Every A/B is blind.

The problem
Running outbound blind is how pipelines quietly die.
Without live metrics, you guess. You keep sending a sequence that's burning deliverability because you don't see the bounce rate climb. You keep follow-ups that nobody opens because you don't know which step kills momentum. The damage is always visible in hindsight — never in time.
02
Bounces climb before you notice
High bounce rates tank sender reputation with ISPs — fast. Without a live bounce counter and deliverability health score, you find out when opens collapse campaign-wide.
domain reputation tanks silently
03
Vanity metrics ≠ pipeline metrics
Total emails sent means nothing. What matters: reply rate per step, bounce trend, warmup score, deliverability health. Dashboards that hide these numbers hide the truth.
false confidence = worst outcome
What you get
Not dashboards. Decisions.
Three views, one source of truth. Account-wide KPIs, per-campaign drill-downs, and deliverability health — all updated live, all queryable by date range.

Total sends, replies, bounces, prospects, leads, campaign status, warmup score, deliverability health — every metric your outbound team needs on one screen. Filter by date range. Watch month-over-month deltas. Spot trouble before it becomes a quarter-long slump.
- Live KPI cards. Every stat updates as sends, replies, and bounces happen.
- Month-over-month deltas. Every card shows +% or −% vs last period.

How it works
Four steps. Live dashboard, zero setup.
Analytics activates the moment you connect an inbox and launch a campaign. No tracking pixel setup, no tag manager, no event schema. It just works.
STEP 01
Connect your inboxes
Every account you send from is tracked. AES-256 encryption. Live SMTP + IMAP validation. Zero config.
60 secondsSTEP 02
Launch campaigns
The moment a sequence goes live, every send, open, reply, and bounce logs to analytics — scoped to your account, bucketed by day.
Real-time captureSTEP 03
Watch signals land
Open-tracking pixel fires on email load. IMAP captures replies. Bounce detection flags failures. Warmup score updates daily.
Live updatesSTEP 04
Act on the data
Drill into any campaign. Spot drop-off steps. Clone winners. Pause losers. Iterate weekly with numbers that actually move pipeline.
Decisions, not dashboardsWhy Sendlio
Most outbound dashboards show vanity, not velocity.
Total sent. Total received. Two numbers that don't tell you which step converts, which account is dying, or whether your reply rate is holding. Sendlio Analytics was built for operators who ship sequences weekly and need to know — today — what's working.
| Capability | Basic dashboards | Sendlio Analytics |
|---|---|---|
| Per-step breakdown | Campaign totals only | Sends/opens/replies/bounces per step |
| Live updates | Daily refresh | Real-time capture |
| Time-series charts | Gapped, misleading | Zero-fill buckets, continuous |
| Deliverability health score | Not included | Rolling per-inbox metric |
| Warmup + campaign in one view | Separate dashboards | Unified panel |
| Month-over-month deltas | Manual calc | +% / −% on every card |
| Campaign status donut | Spreadsheet | Total / Active / Completed visual |
| Open-tracking toggle | Always on | Per-campaign opt-in |
Reliability + data quality
Metrics you can trust. Infrastructure that holds up.
Analytics only matters if the numbers are right. Every metric in Sendlio is captured at source, scoped to your account, and charted with zero-fill bucketing — so you never see a gap that isn't really there.
Source-captured metricsOpens fire at email load. Replies log at IMAP capture. Bounces flag at send failure. No aggregation lag.
Zero-fill time-seriesEvery day in a range is bucketed — days with no activity show zero, not gaps. Continuous, honest charts.
Scoped to your accountEvery query filtered by user_id at the first pipeline stage. Your metrics are yours — never cross-tenant visible.
Historical retentionDaily snapshots retained for the full account lifecycle. Pull any range, today or 18 months ago — the data is there.

FAQ
Answers operators ask. In plain English.
No dev jargon. No marketing fog. Real questions with real answers — the same ones we give on sales calls.
What metrics does Sendlio track?
Sends, opens (unique + total), replies, bounces, click estimates, campaign progress %, deliverability health, warmup score, and per-step breakdowns of all of the above. Plus prospect and lead counts, campaign status splits, and month-over-month trends.
How often does the dashboard update?
Live. Opens fire the moment an email loads. Replies log the moment they land in your inbox. Bounces flag the moment they fail. Every metric reflects reality within seconds — no batching, no stale data.
Can I filter by date range?
Yes. Built-in ranges for Today, This Week, This Month, and Last 30 Days — plus a custom range picker. Every chart and KPI respects the selected window. No forced reloads.
Account-wide or per-campaign?
Both. The main dashboard gives you account-wide KPIs across every campaign and every account. Click any campaign and you drop into per-campaign analytics with per-step breakdown — see exactly which sequence step converts and which kills momentum.
What about open-tracking privacy?
Open tracking is opt-in per campaign via a 1×1 tracking pixel. Turn it off per campaign if you run text-only sequences or want maximum inbox placement. We never track anything the user hasn't enabled.
Can I export analytics?
Metrics sync back to your data layer via API. Custom CSV exports on request. Roadmap includes native export to Google Sheets and CSV download by date range.
What is the Deliverability Health score?
A rolling per-inbox score (0–100) derived from bounce rate, reply rate, spam-rescue count, and warmup consistency. Visible on the main dashboard alongside your warmup score. Watch it drop and you catch a degrading account before open rates tank.
How do you avoid misleading gaps in charts?
Zero-fill bucketing. Every day in a date range is included in the chart — even days with zero activity. No hidden gaps, no misleading week-over-week jumps, no "Monday looks great because Sunday had no data".
