Website monitoring with SMS alerts

Uptimia checks your sites, certificates and checkout flows from outside your network and texts the number you answer when one fails. There is no messaging vendor to sign up with and no second invoice — the texts go out on our account, starting with the next failed check.

Text alerts are built in

Add your phone number and Uptimia texts it when a check fails. Sending is part of your plan — there is nothing else to connect and no separate bill to pay.

The usual way to add texts

Texts through a separate SMS service

A check fails
you would like to know by text
sign up · register
A messaging vendor
API keys, sender IDs, monthly billing

Uptimia supports that route too, through the Twilio integration. But it is a procurement task before it is an alert, and afterwards the carrier invoices you directly for every message.

Texts in Uptimia

Texts straight from Uptimia

A check fails

Your phone
a text, sent by us

The number sits in your contact list beside the email addresses. Uptimia sends the message on its own account, out of the monthly text allowance your plan already includes.

You are not buying a messaging product. You are typing a number into a contact. Here is a Sunday evening, end to end:

Nine monitors down, one text

One database failure can take down every check that depends on it. Monitors that share an escalation policy fold into a single incident — one text when it starts, one when it is over.

Set up SMS alerts in three steps

There is nothing to connect and nothing to install. Add your phone number, point your monitors at it, and decide when it may ring.

Everything you monitor can text you

A homepage ping only proves the homepage. A certificate about to expire, a checkout failing halfway, a server filling its disk, a backup that never ran — every check you run can text the same phone.

SSL certificatesExpiry, with weeks of warning

A text only when it matters

A text interrupts, so Uptimia sends as few as possible: a failure is confirmed from several locations before anything goes out, related monitors share one incident, and the quiet hours you set stay quiet.

Confirmed, then sent
One unlucky probe never gets to wake you.
Up to three regions must agree before an uptime alert sends
Retried up to five times if sending fails
A recovery text follows when the check goes green
no single-probe false alarms
One text per incident
Monitors on one escalation ladder — Professional plan and above — alert together.
Monitors sharing a policy fold into one text
Monitors that join later update it
One recovery closes the whole incident
one incident, one text

Quiet hours per person; maintenance texts nobody.

Planned windows text nobody at all

What sits behind the text

The text tells you something failed. Behind it sit 171+ checkpoints, the full incident record, response-time charts and a status page your customers can read — for the moments you want more than a notification.

Where the evidence lives

The text names the monitor, its status and the minute the incident started. The dashboard keeps the rest: which locations confirmed the failure, what the response looked like, and an acknowledge button if you skipped the link.

A sender you recognise

Where carriers allow a name as the sender, the text arrives from Uptimia; elsewhere it comes from a fixed number you can save as a contact.

Included, not invoiced

Texts come out of a monthly allowance that resets on the 1st. No per-message fee, and nothing to top up mid-month.

Acknowledge from the text

The alert carries a link — one tap says you are on it and stops the escalation, no login needed.

When one text should become two

On an escalation policy — Professional plan and above — an ignored alert climbs: the next number after the delay you set, then another channel entirely. Planned maintenance sends nothing at all.

How website monitoring SMS alerts work

Uptimia checks your websites from 171+ external locations and texts your phone when a check fails. The message says which monitor failed, what went wrong and since when — and when the site recovers, a second text reports how long it was down.

“Email at night is good enough”

Mail waits. A text arrives

Checkout down 02:40
the email is sent immediately
unread until 07:00
The inbox
batched and silent overnight

The mail was delivered on time and read four hours late, because a phone treats mail as reading material. Email is the right channel for the evidence — it is the wrong one for the interruption.

Outside probes + a contact of type SMS

Outside probes, then a plain text

171+ locations
loading the real page
1 text · 1 credit
Any handset
no app, nothing to install

The check runs outside your infrastructure, so it sees what a customer sees; the text arrives on the one channel a phone still shows unasked. Neither end needs anything installed.

SMS alerts FAQ

01How is this different from the Twilio integration?+
This is the built-in channel: you type a phone number, Uptimia sends the message on its own account, and it counts against the SMS allowance in your plan. The Twilio integration is for teams who would rather own the pipe — your account, your sending number, your bill, and no allowance to run out of. Same alerts either way; the difference is who the carrier invoices.
02Do I need an account with a messaging provider?+
No. That is the whole point of this channel — there is nothing to sign up for, no API key to paste and no sender ID to register. SMS is a contact type in Uptimia, exactly like an email address: add the number, attach it to monitors, done.
03How many texts do I get, and what do they cost?+
Each plan carries a monthly SMS allowance that resets on the first of the month — 20 during the 30-day trial, then 50 on Basic, 150 on Professional and 500 on Enterprise. One message spends one credit, and the code that verifies a new number spends one too. Uptimia adds no per-message fee, and there is no top-up to buy: if you need volume beyond the allowance, the Twilio integration bills the carrier directly instead.
04What happens if the allowance runs out?+
Text alerts pause; every other channel you have configured keeps going, so you are not left unmonitored. Uptimia emails you once a month when the balance drops to 20% remaining, and again when it reaches zero, and the skipped messages are recorded in your SMS log — it is never a silent stop.
05Which countries can Uptimia text?+
North America and most of Europe, plus Japan, South Korea, Australia, New Zealand, Singapore, India, Brazil, Chile, Argentina, the Philippines, Türkiye, Taiwan, Hong Kong, the UAE, Oman, Bahrain and Uruguay. Numbers outside that list are declined when you add them rather than failing silently later. If your number is not covered, the Twilio integration or WhatsApp will usually reach it.
06Who does the message come from?+
The sender name Uptimia, so it is recognisable before you open it. A number of countries do not permit alphabetic sender names; there the text arrives from a fixed long code instead, which you can save as a contact once and recognise from then on.
07Can I tap something in the text?+
Monitors on an escalation policy (Professional plan and above) get a signed acknowledge link in every down text — it works without logging in, and one tap pauses the ladder. The link is dropped whole, never truncated, when the message would otherwise pass 160 characters. Monitors alerting all recipients at once send plain text with no link. Messages are in English on every account.
08What if the message fails to send?+
Uptimia retries with a growing delay, up to five attempts, before giving up on that notification. What it cannot promise is a delivery receipt: carriers do not reliably report one, so treat the escalation ladder — a second number, then another channel — as the real safety net rather than any single text.
09Can several people get the texts?+
Yes. Each number is its own contact, so add one per person and attach whichever monitors matter to them. Quiet hours belong to the person who owns the contact — set account-wide, not per monitor — which is how a rotation works in practice: your number sleeps, the on-call number does not.
10Which monitor types can text me?+
Every one of them — uptime, transactions, page speed, real-user monitoring, SSL, domains, malware, servers, heartbeats, blacklists, DNS and API checks. Each writes its own one-line message, and each sends its own recovery text when the check goes green.
