Alerts & email reports
Weekly and monthly email summaries, spike and drop alerts, notable backlink alerts, and webhook delivery to Slack or Discord.
Everything here lives on your site's Alerts screen and is configured per site. Reports and alerts are email-first, with an optional webhook for Slack, Discord or your own endpoint.
Email reports
- Weekly report: a summary of the past week's traffic, sent every Monday.
- Monthly report: the same for the past month, sent on the 1st.
Traffic alerts
Numative checks your daily visitors and emails you when they move sharply:
| Alert | Fires when | Threshold |
|---|---|---|
| Spike alert | Daily visitors rise by at least the threshold. | 5% to 1000%, default 50% |
| Drop alert | Daily visitors fall by at least the threshold. | 5% to 100%, default 50% |
| Page moves | A page, or the site total, sits outside its own usual range for the day: measured against that page's prior four weeks, with the site's overall move taken out. One digest a day, each page with the cause Numative detected. | None to set; the spike and drop thresholds scale its sensitivity. On by default. |
| Site health | The site is confirmed down, degraded, or silent (traffic no longer reaching Numative). One email when the incident is confirmed, one when it ends. See Site health. | None to set. On by default. |
Alerts point at the pages and sources behind the move. For the full picture of every page that moved, see the Anomalies view.
A site with both Google Analytics and Numative tracking also gets a Measure against choice. The two sources count differently, so a threshold has to be checked against one of them; checking both would fire on the union of their noise and email you about a spike the dashboard does not show.
Backlink alerts
With backlink tracking enabled, Notable backlinks emails you when a high-authority link (Domain Rating 60+) to your site is gained or lost.
Core Web Vitals alerts
Vitals regression emails you when LCP, INP or CLS drops a grade in Chrome field data. Improvements are not alerted on: a metric getting better is not something anyone needs to be interrupted for. See Speed.
Delivery
- Recipient emails: comma-separated. Empty means the organization owner receives everything.
- Webhook URL: optional. Alerts also POST a JSON payload to this URL, which works with Slack and Discord incoming webhooks or any endpoint you run.
