What's OK by text, what goes to email, and what isn't allowed
UserAlertX texts only you — your own verified phone, never anyone else. Even so, phone carriers have rules for every business text message, and we follow them. Here are real examples of what goes by text, what goes to your email instead, and what isn't allowed at all. We keep adding to this page.
Personal, event-driven alerts — something happened, and you want to know:
| Example alert | Kind |
|---|---|
| Claude Code: task finished - 14 files changed, all tests pass. | AI agent done |
| Your agent wants to deploy to production. Reply Y to approve, N to stop. | TeXt Approval |
| Backup done: 42 GB, no errors. | Script / cron job |
| Server web1: disk 92% full. | Server needs you |
| CPU hit 95% on build box for 10 minutes. | Monitoring |
| Front door opened at 2:14 am. | Home automation |
| Garage freezer is at 15 F - door may be open. | Sensor |
| Price drop: the Dell monitor you watch is now $189. | Page watcher |
| Printer is low on toner; paper back in stock at Costco. | "In stock" is fine — it's not about the stock market |
| New mail from your boss: Re: Q4 plan. | Agent inbox |
| Reminder: dentist at 3 pm tomorrow. | Reminder |
Carriers don't allow some topics in a text at all, even one you send to yourself: stocks and trading, crypto, loans and debt, cannabis, tobacco and alcohol, firearms, gambling, and adult content. Before every text, UserAlertX checks the alert. If it touches one of these, the whole alert is emailed to you and your phone gets a short "check your email" notice. Nothing is lost. The check is careful on purpose, so it also catches some everyday words:
| Example alert | Why it goes to email |
|---|---|
| AAPL crossed $250. | Stock price |
| TSLA is down 4% today. | Stock price |
| Earnings report posted for your company. | Stock market words |
| Bitcoin is above $70,000. | Crypto |
| Mortgage rates fell to 5.9%. | Loans |
| Your bets settled: +$40. | Gambling |
| Wine club shipment arriving tomorrow. | Alcohol |
| The beer fridge is at 50 F. | Alcohol — an everyday alert, but the word "beer" is enough |
| Poker night moved to Friday. | Gambling word |
| Gun safe opened. | Firearms word |
| Weed the garden today - rain coming. | "Weed" — the check can't tell gardening from cannabis |
Tip: reword an everyday alert to keep it a text — "Garage fridge is at 50 F" goes by text. Or send those alerts by email from the start (see What can't be sent by text).
method=email) is often best.These are the US carriers' rules for every business that sends text messages, through the text-message providers we use. Carriers can fine each message that breaks them and shut down the numbers that sent it — for everyone using those numbers. Keeping every account inside the rules keeps texting working for all of us.
