Each of the six alerts sends a different email. Here's what each one actually says and points you toward.
Subject: "VerifyFiltering Alert: [device] is offline." The email states the device's last-seen timestamp and names the two most common causes — the agent has stopped, or the device is powered off — then links to your dashboard. For the full troubleshooting sequence, see why a device shows Offline, and what to check first.
Subject: "VerifyFiltering: New device registered — [device]." The email names the device and its OS, and its instruction is different from most of the others: if you didn't set this device up yourself, it tells you to review your account immediately, since someone else may have your license key. Along with the plan changed email below, this is one of the two alerts where the right response is a security check, not a troubleshooting step.
Subject: "VerifyFiltering: Device could not reconnect — [device]." This links to your device list
instead of your dashboard. The email already contains the full fix in its own text: the device was
previously removed, removal is permanent, and running the agent with --reset then
reinstalling will bring it back as a new device. See
re-registering a device after you remove it for the
full explanation of why that's necessary.
Subject: "VerifyFiltering: Your plan changed to [plan]." Names both your old plan and your new one when there was a prior plan to name, or just states your current plan if this is a brand-new subscription. This links to your Plan & Billing page, not your dashboard. Like the new device email, it carries a security instruction rather than a troubleshooting one: if you didn't make the change yourself, review your account immediately.
Subject: "VerifyFiltering Alert: Low score on [device]." The email states both numbers — the device's current score and the threshold you set — so you don't have to look either one up separately, and points you to your dashboard specifically to review which categories are failing on that device.
Subject: "VerifyFiltering: Weekly device summary." Unlike the other five, this one isn't triggered by a problem — it's a routine Sunday summary listing every monitored device with its score. That score is explicitly an average across all of a device's categories, which is a different number than what triggers a score-threshold alert (that one looks at a device's single worst-scoring category, not its average) — worth knowing so the two percentages aren't compared as if they measure the same thing.
All six come from the same sender and close with the same sign-off — there's nothing in the "from" address itself that distinguishes one alert type from another; the subject line and body are what tell you which one you're looking at.
