SMS alert features that get alarms to the right phone
Welco's 12 SMS alert features get the alarm that matters to the person on call as one short text, and nobody else is woken. They decide which alert emails become texts, whose phone gets each one and what it says. Every feature acts on the emails your systems already send.

An alert email from alarms@wwtp.example.gov arrives. The Welco rule “Pump alarms after 6 PM go to the night phone” trims it, and Night operator, on call gets one text: “Welco: [Headworks] Influent Pump 2 overload trip at 2:37 AM. Reply STOP to opt out.”
Night operator, on call received: Welco: [Headworks] Influent Pump 2 overload trip at 2:37 AM. Reply STOP to opt out.
What Welco's SMS alert features do for your team
Every feature belongs to one of four jobs. Start with the job your alarms need most.
The right person hears it
Rules, time windows and several phones per alert put each alarm in front of the person who should act on it.
Texts stay short and calm
A long email becomes one line, a retried email buzzes once, and a storm of alarms stays a handful of texts.
You decide who can send
Only the systems you approve can text your team, and test mode lets you try a change before it goes live.
Proof by morning
Each text shows whether it was delivered, and replies from the phone land back in your mailbox.
One pump alarm, followed through every feature
Here is the overload trip from the top of this page. Watch which feature acts at each moment of a treatment plant's night.
The plant's HMI emails an overload trip
ALARM: Influent Pump 2 Overload Trip, Tag IP2_OL_TRIP, Priority 1Approved sender, matching rule
The email comes from the HMI's approved address, so it's accepted. The body says TRIP, so the pump alert rule matches.
The night window picks two phones
It's after 6 PM, so on-call routing picks the night operator. Headworks trips are critical, so the rule also copies the lead operator.
Trimmed to one line, sent once
The group, the tag and the time stay, and the footer goes. The mail server retried, but duplicate protection kept it to one text per phone.
The night operator's phone buzzes
Welco: [Headworks] Influent Pump 2 overload trip at 2:37 AM. Reply STOP to opt out.The operator answers from the truck
Heading in, there in 20The reply reaches the plant's alerts mailbox
The day crew reads it before their shift begins. The reply does not clear the alarm on the HMI.
Reply from the night operator: Heading in, there in 20The superintendent reviews the night
Delivery reports show both texts as delivered, in order. Nobody else's phone buzzed.
Times are an example. Text delivery depends on mobile networks.
How Welco handles an alert in 3 steps
Every feature on this page works somewhere along this path. The email-to-text walkthrough shows it end to end.
Your system emails your Welco address
Point the alert email you already have at your Welco address. Only approved senders get through, so nobody else can text your team.
Rules decide what happens
Rules pick the phones, trim the text and drop the noise. Time windows send night alarms to the night phone, and flood control keeps a burst in check.
The right phone gets one short text
Each confirmed phone gets one text that starts with
Welco:. Voicemail and PDFs arrive as tap-to-open links, and replies come back by email.

Reach the right person
Use these when the real question is who should see this alarm, and when.
Alert rules
Match on the sender, the subject or words like TRIP and DOWN, then pick whose phone gets the text.
On-call and after-hours routing
Days go to the whole crew. Nights and weekends go to the one person on standby.
Several phones per alert
Text a critical alarm to two or three people at once, so one flat battery can't hide it.
Tap-to-listen voicemail and file links
Voicemail audio, photos and PDFs arrive as a short private link the on-call person opens from the text.
Keep texts short and calm
Use these when the phone buzzes too often or the texts are hard to read at a glance.
One-text alerts
Cut a long alert email down to the site, the fault and the time. Our guide to alert text best practices shows what to keep.
Alarm flood control
Drop the all-clears and cap a burst, so the night a power blip trips every station stays readable. That night has a name, an alarm flood.
No duplicate texts
When a mail server delivers the same email twice, each phone still gets the alert one time.
Example alerts these features produce
Three texts from three kinds of systems. Each one was trimmed to a single line and sent to the phone on call.
- SCADA well alarm: Welco: [Pump Station 2] Well 3 level LOW LOW alarm at 1:58 PM. Reply STOP to opt out.
- IT host down: Welco: [Server] Host DOWN - db-01 (10.5.160.9) at 3:12 AM. Reply STOP to opt out.
- Urgent voicemail: Welco: New voicemail on Tech Urgency Line from (231) 555-0100, 0:36. Reply STOP to opt out.
Stay in control of who can text your team
Use these to decide which systems may send, and to try every change safely.
Approved senders only
Mail from an address you haven't approved never turns into a text, so a stranger can't reach your crew.
Test mode
Run a new rule or system against real alerts and see each text it would send, with no texts out and no credits used.
Dedicated alert number
Alerts come from a number only your company uses, available in the US and Canada.
Prove delivery after a long night
Use these when someone asks the next morning whether the alarm got through.
Delivery reports
See whether each text was delivered and, if one wasn't, the reason written in plain English.
Replies by email
A reply to an alert text is emailed to the alert's sender, so the day crew sees who answered and what they said.
