SMS Program

CropStack Weather Freeze Alerts

Time-sensitive freeze and frost warnings by text message.

What the program is

CropStack Weather is a freeze-alert and forecast service for commercial farms in the United States. Growers who opt in receive time-sensitive SMS warnings when freezing temperatures are forecast to threaten their registered crop blocks, so they can act (for example, start irrigation for freeze protection) before damage occurs. This is the same weather-watch judgment growers previously relied on over the phone, delivered automatically to the people responsible for the crop.

Messages come from our dedicated number +1 (689) 407-8425. This is a transactional alert program, not marketing — we never send promotional texts.

How to opt in

Consent is collected in the grower's own account. SMS is off by default — a grower must affirmatively check the SMS box and provide a valid mobile number. The steps:

  1. Sign in at weather.cropstack.ai using magic-link email sign-in.
  2. Add your farm and at least one crop block.
  3. Open the farm's Contacts section and add a contact, entering a valid mobile phone number.
  4. Check the "SMS" box under "Receive alerts via" to consent to text messages. It is unchecked by default. The form will not save an SMS opt-in without a valid mobile number.
  5. Choose when to be texted (e.g. only at warning or critical risk levels) on the notification-preferences form on the same page.
CropStack Weather Contacts form. The SMS opt-in checkbox under 'Receive alerts via' is unchecked by default, with a message-and-data-rates disclosure beside it.
The Contacts form. The SMS opt-in checkbox is unchecked by default; the grower must check it and supply a mobile number to consent.
Notification preferences: a grower chooses the minimum risk level that triggers an SMS, plus optional quiet hours and timezone.
Notification preferences let a grower control which risk levels trigger an SMS.

Message frequency

Frequency depends entirely on the weather. On most nights you receive no messages. During an active freeze event you may receive multiple messages in a single night as conditions change. Over a typical Florida winter this is a handful of nights per season.
