When it breaks, wake the right person.

Tocsin turns alerts from your monitoring tools, by webhook or plain email, into texts, emails and phone calls to whoever is on call. It escalates until someone answers, and they can take it with a one-word reply.

Works with the monitoring tools you already use. If it can send a webhook or an email, it can wake your team.

Product names belong to their owners. Tocsin is not affiliated with or endorsed by them; it receives their standard webhook and email notifications.

Features

Everything between “alert fired” and “someone’s on it”

Tocsin does the part monitoring tools leave out: getting a human’s attention reliably, and escalating when they don’t respond.

Texts, emails and phone calls

Reach people the way that works at 3am. Calls read the alert aloud in a clear British voice, twice.

Acknowledge from anywhere

Reply “ACK” to the text, press 1 on the call, or click a button in the dashboard. Escalation stops the moment anyone does.

On-call schedules

Daily, weekly or fortnightly rotations, with overrides for holidays and swaps. Tocsin always knows who is on call right now.

Escalation policies

Text first, call two minutes later, then the next person or a manager. You choose who, when and how, step by step.

Smart routing

Send database alerts to the platform team and billing alerts to finance, by source and severity.

Alerts by webhook or email

One webhook for your own scripts, and a private email address per tool. If it can send an email, it can raise an alert.

See what was sent

Every alert shows each text, email and call, and what happened to it. Bounced addresses are recorded and counted.

Never a silent miss

If an alert reached nobody, because of a missing rule or an empty rota, the dashboard says so instead of failing quietly.

Built for many teams

Each organisation’s data is kept separate, with its own people, API keys per tool, and roles for admins and responders.

Acknowledge in seconds

Take the alert without opening a laptop

At 3am, a one-word reply beats finding your laptop. Tocsin matches your reply to the right alert and stops the escalation.

  • Reply ACK to acknowledge, or RESOLVE to close it.
  • On a call, press 1 to acknowledge.
  • Several alerts open? Your reply goes to the latest, and tells you how many are left.
  • Everything is recorded, including who took it and when.

Out of hours, the right engineer is woken for a gas leak, a broken lift or a failed chiller, and the team can see who is on it.

Who it's for

Built for teams that can't ignore a 2am problem

If something breaks out of hours and a person has to deal with it, Tocsin gets the right person on the phone. See how it fits your work.

Property and block managers

A lift, boiler or fire alarm fault at 2am reaches the engineer covering that building, and escalates until someone answers.

How it works

From alert to answered in three steps

Connect your monitoring once, then let Tocsin handle who gets contacted and when.

  1. Send an alert

    Point your monitoring at your Tocsin webhook, or at its private email address. Duplicates are merged.

  2. We find who’s on call

    Routing rules pick the schedule, and the schedule says who is on call at that moment, including any overrides.

  3. We escalate until it’s handled

    Your policy runs step by step. Reply ACK, press 1, or click acknowledge, and it stops.

curl -X POST https://api.tocsin.co.uk/alerts \

  -d '{"source":"grafana","severity":"critical",
       "summary":"Production DB primary unreachable"}'

Questions

Good to know

How do my monitoring tools send alerts?
Two ways. Use the webhook with your API key from any script or tool that can make a web request, or give a tool its own private Tocsin email address and point its email notifications there. The subject becomes the alert title, and words like “critical” or “P1” set the severity.
Can I acknowledge without using the dashboard?
Yes. Reply ACK to the text, or press 1 during the phone call. The alert is acknowledged and escalation stops. Replies need a text sent from a real phone number, which Tocsin sets up for you.
What if nobody is on call, or a rule is missing?
The alert is still saved, and the dashboard shows a clear “No one was notified” warning with a hint about what to check, so it never fails silently.
Where is my data kept?
In Amazon Web Services in London. Each organisation’s data is kept separate, and API keys are stored in a form that can’t be read back.
How much do texts and calls cost?
Plans start at £10 a month for Starter and £25 a month for Team. Texts and calls use prepaid credits, one credit each. Credits start at 20p each and cost less in bigger bundles, down to 10p each, so you only pay for what you send. Emails are always free. All prices are shown + VAT: 20% UK VAT is added at checkout.
Who makes Tocsin?
Tocsin is built and run by Espresso Group, a UK IT company. Questions or support go to support@tocsin.co.uk and reach a real team.
How do I try it before I rely on it?
Create a free trial, add yourself and a schedule, then press “Send test alert”. The 14-day trial sends alerts by email so you can check your rota, routing and escalation. Texts and phone calls start when you pick a plan. If the trial ends first, we keep your data and nothing is lost.
