Setting Up Notifications

LMKwhen delivers alerts via three channels: SMS, email, and Slack. Configure your preferences in Delivery Channels.

SMS​

  1. Go to Delivery Channels
  2. Click Add channel and pick the SMS tab
  3. Enter a label and the phone number in E.164 format — for example, +15551234567
  4. Click Add Channel. We text a confirmation link to that number
  5. Whoever holds that phone opens the link and taps Confirm

Until step 5 is done the channel shows Not verified, and no alerts are sent to it. Once confirmed it shows Verified and starts receiving alerts. This applies even when you add your own number.

The confirmation link is good for 7 days. If it expires, or the text never arrived, click Resend on the channel to send a new one.

Adding a number that isn't yours​

You can add a team member's or a site contact's number, but you can't opt them in on their behalf — they have to tap Confirm on the link themselves. Until they do, the channel stays dark. The text they receive names you and your organization so they know who is asking.

If they tap Decline, the channel shows Declined by recipient and stays dark. Talk to them before sending another link.

Because the person adding a number often isn't the person carrying the phone, LMKwhen never enables a number on the account holder's say-so alone. The recipient confirms on a web page, and that agreement is recorded against the number.

Our full opt-in flow, message wording, and consent-record practices are published in the SMS Opt-In Compliance Documentation.

SMS opt-out and re-enable​

If you reply STOP to any LMKwhen SMS, your number is opted out and alerts stop immediately. To re-enable:

  1. Go to Delivery Channels
  2. Find the opted-out number — it shows an amber warning
  3. Click Re-enable SMS alerts and confirm

You can also re-enable by texting START to the same number.

SMS quota​

Your plan includes a monthly SMS limit. You can see your current usage in Delivery Channels. The quota resets on the first of each month. If you hit your limit before month end, upgrade in Settings → Billing.

Email​

Email notifications use your account email address automatically. No setup required. You can disable email notifications per alert rule if you prefer SMS or Slack only.

Slack​

  1. Go to Delivery Channels
  2. Click Connect Slack
  3. Authorize LMKwhen in your Slack workspace
  4. Choose which channel receives alert notifications
  5. Save

Each organization can connect one Slack workspace. Alert messages include the location name, alert type, and a link to view details.

Routing alerts to specific channels​

Once your channels are set up, you can control which alerts reach which channels:

  • Priority filter — channels can opt to receive only High-priority alerts
  • Tag subscription — channels can subscribe to specific tags (Standard plan or higher)
