The problem

The alert you miss is the outage you pay for.

An uptime monitor is only as good as the alert it sends. Most tools default to email — the channel where a downtime notice lands between a newsletter and a calendar invite, unread for 40 minutes. Slack is better, until the channel is muted on a Saturday. By the time someone notices, customers already have.

WhatsApp changes the math. It's a personal-priority channel with push notifications people don't ignore, read receipts, and group chats your on-call rotation already uses. WhatsApp messages are typically read within minutes — open rates run far higher than email's (commonly cited around 95% vs ~20% for email). A downtime alert there is read in seconds, not after the next inbox refresh.

  • Delivered in seconds, with a push your phone actually surfaces
  • Works on the device your team carries everywhere
  • Group chats for the whole on-call rotation
  • No new app to install, no dashboard to keep open

Three steps to your first WhatsApp alert

Setup takes about a minute. No phone-system integration, no developer required.

1

Add a monitor

Paste the URL, host, or port you want watched. Pick a check interval — down to 1 minute on paid plans, 30 seconds on Pro and Business.

2

Connect WhatsApp

Add your WhatsApp number (or a group) as an alert channel and confirm it once. Reuse it across every monitor in your account.

3

Get alerted

The moment a check fails, the alert hits WhatsApp — and a recovery message follows the instant it's back, with the total downtime.

Inside the alert

Enough detail to act before you open a laptop.

A good alert answers "what, where, and how bad" without a single click. Every UptimeClaw WhatsApp message is formatted, not a raw log line:

  • Monitor name & URL — know exactly which service failed
  • Status code & reason — 503, timeout, SSL error, keyword missing
  • Region — which checkpoint saw the failure, so you can spot regional issues
  • Response time — catch the slow-then-down pattern early
  • Recovery + duration — an automatic "all clear" with total downtime

Want it everywhere at once? Pair WhatsApp with email, webhooks, Slack, Discord, or PagerDuty and set escalation order — WhatsApp first, email as backup.

WhatsApp alerts FAQ

Which plans include WhatsApp alerts?

WhatsApp alerts are included on every plan — even the free one (5 monitors). Paid plans (Solo $9/mo and up) add more monitors, faster checks, and more regions.

How fast does a WhatsApp alert arrive?

As soon as a check fails. On paid plans with faster checks (60-second on Solo, 30-second on Pro and Business), downtime is detected and the WhatsApp message is sent immediately — typically within seconds of the failure.

Can I send alerts to a team group?

Yes. Point the WhatsApp channel at a group chat so your whole on-call rotation sees the same alert and recovery message at once — no fan-out, no missed handoffs.

What if I want more than WhatsApp?

Combine channels. UptimeClaw can fire WhatsApp, email, webhooks, Slack, Discord, PagerDuty, and Microsoft Teams together, or in an escalation order you define. WhatsApp first, email as a fallback is a popular setup. Slack vs WhatsApp →

Do I need to install anything?

No. There's no app to install and no phone-system setup. Add your number, confirm it once, and every monitor in your account can alert it.
