What It Is

Did It Send is a reverse monitoring tool designed for IT operations and MSP use cases. Instead of actively polling servers or devices, it listens for the email notifications and check-ins that systems already send, such as Veeam backup success emails, firewall or UPS alerts, NAS notifications, scheduled reports, and script execution results. Its main focus is detecting “missing expected notifications” — in other words, silent failures.

Core Capabilities

Based on the page content, the product lets users create checks and define when a signal is expected: daily, weekly, on a cron schedule, or as event-driven notifications triggered by the device itself. Users point device or system alerts to a unique check address, and Did It Send determines whether the email arrived on time and whether its content indicates an issue. Its advantage is that it requires no agent installation, no SNMP, and no additional firewall rules, making it suitable for devices that traditional RMM tools may not cover well, such as switches, firewalls, NAS devices, and UPS units.

Pricing and Delivery

The site is currently in Beta / Early Access and offers Request Access, noting that no credit card and no commitment are required. The page does not disclose official pricing, plans, seat limits, check frequency limits, or alert channel quotas, so the commercial cost cannot yet be assessed. Information on whether it is open source or closed source, self-hosting options, and API/SDK availability is also not present in the main content.

Pros and Cons

Its strengths are a clear concept and a very short deployment path: create a check, configure the device to send email, and verify it on schedule. It can help cover common blind spots such as shared mailboxes no one checks, notification settings being changed by mistake, mail flow failures, and backup software silently stopping. The downside is that the currently public information is limited. There are no visible details on specific integrations, notification methods, permission management, auditing, data retention, security compliance, or SLA. It also depends on the original system being able to send email; if the entire email delivery path is unavailable, the product would need reliable external alerting of its own, but the page does not elaborate on this.

Who It’s For and Access from China

It is suitable for IT operations teams, MSPs, small teams, and organizations without a complete RMM/NMS setup that want a lightweight way to monitor backups, scripts, reports, and edge-device notifications. For teams that already have a monitoring stack, it is more of a blind-spot coverage tool. The main content does not provide information about access from mainland China, and payment methods are also unknown. If network access or payment is restricted, alternatives include Healthchecks.io, Cronitor, Uptime Kuma, Better Stack, or using email rules together with an existing alerting platform.
