The reason, written so anyone can act on it

On. The phone gets 2 texts.

With Delivery reports off, the phone gets 2 texts: Welco: [Cooler 2] Temp 46F, above 41F limit at 1:22 AM. Reply STOP to opt out. Status: failed With it on, it gets 2: Welco: [Cooler 2] Temp 46F, above 41F limit at 1:22 AM. Reply STOP to opt out. Not delivered: this phone replied STOP. Texting START turns alerts back on.

What you stop guessing about

  • Where the alert stopped

    See whether the email reached Welco, which rule it matched and what happened on each phone.

  • A reason you can act on

    A phone that's off, a typo in a number or a STOP reply each has its own label and its own fix.

  • A record for the audit

    Export the feed as a CSV file with each email, each text and the result for every phone.

  • Credits back on rejected texts

    A text rejected at the moment it's sent gets its message credit refunded, and our support team is alerted.

What each delivery result means

Each line in the feed covers one email and the texts it became. Reports cover every text sent by Welco's alerting features.

Delivered

What it means
The mobile network sent back a receipt confirming delivery to the phone.
What to do
Nothing. If the person still missed it, check their phone's quiet hours.

Phone off

What it means
The phone was powered off or out of coverage.
What to do
Ask them to keep the on-call phone charged and on.

Number not recognized

What it means
The number doesn't exist or was typed wrong.
What to do
Fix the digits, or ask for their current mobile number.

Landline

What it means
The number can't receive texts.
What to do
Use a mobile. See why a landline can't get alerts.

Replied STOP

What it means
The person opted out, and the network blocks texts until they send START.
What to do
Ask them to text START to your alert number.

Dropped or blocked

What it means
The email matched a drop rule or came from an unapproved sender, such as Blocked: sender not in allowlist.
What to do
Approve the sender or adjust the rule if the alert should have gone out.

A real example: the cooler alarm nobody saw

A walk-in cooler logger emailed at 1:22 AM. The night manager's phone stayed quiet. The report showed why.

Alert email from alarms@logger.example.com, subject “Alarm: Cooler 2 High Temperature”. Welco trims it to one text of 80 characters: “Welco: [Cooler 2] Temp 46F, above 41F limit at 1:22 AM. Reply STOP to opt out.”

Text received: Welco: [Cooler 2] Temp 46F, above 41F limit at 1:22 AM. Reply STOP to opt out.

Weeks earlier, the manager had replied STOP to clear a text by mistake. The report said so in one line. One START text later, alerts were back on that phone.

Trace a missing alert in 3 steps

Most questions about a quiet phone are answered in the feed, without a support ticket.

  1. Find the email in the feed

    Every email Welco receives is listed, including dropped and refused ones. If it isn't there, the problem is before Welco, usually a mail setting or an unapproved forwarding address.

  2. Read the result for each phone

    Check the label on the phone that stayed quiet. A new phone that has never had an alert, or someone who switched carriers, shows up here first.

  3. Fix it and send a test

    Correct the number, approve the sender or ask for a START text. Then send a test alarm and watch its result come in.

Do failed or blocked texts use credits?

  • Carrier filtering shows up too

    Mobile networks sometimes filter texts they think are spam. The report says when a text was blocked, and what gets alert texts blocked lists the usual causes.

  • Drops are free

    Emails dropped by a rule or refused as unknown use no credits at all.

  • Undelivered texts still count

    A text uses its credits once it is handed to the mobile network, even if the network then fails to deliver it. The delivery rates disclosure explains why.

  • Refused senders explained

    Most blocked emails trace back to approved senders. The feed names the address that was turned away.

  • Check before go-live

    Test mode shows what a new setup would send, and the report confirms each phone once it goes live.

Frequently asked questions

How do I know if an alert email reached Welco at all?

Look for it in the feed. Every email Welco receives is listed, including ones that were dropped or refused. If the email isn't there, the problem is before Welco. It's usually the system's mail settings or an unapproved forwarding address.

Why does a text show as delivered when the person says they never saw it?

Delivered means the network handed the text to the phone. A muted phone, a blocked contact or a busy lock screen can still hide it. Ask them to save your alert number as a contact and allow texts from it at night.

Do I get a credit back when a text isn't delivered?

No. Once Welco hands a text to the mobile network, its credits are used, even if the phone never receives it. Texts that Welco rejects or holds before sending use none. Welco doesn't promise or publish a delivery rate, because carriers, phones and coverage decide the last step.

Can I export delivery reports for an audit?

Yes. The feed exports as a CSV file. It lists each email, each text and the result for every phone.

What should I do when a report says the number isn't recognized?

Check the number for a typo or a missing digit, then fix it in the rule. If the number looks right, the person may have changed carriers or lost the line. Ask for their current mobile number and have them confirm it with YES.

Does a delivery report show that someone acted on the alarm?

No. Reports stop at the phone and say nothing about who read or handled the alarm. When the on-call person replies, the reply is emailed to the alert's sender, which is the closest thing to a record of who took it.
