SMS Notifications

Receive a text message the moment someone submits your form.

Basin can send an SMS to your phone whenever a new submission comes in. This is useful when you need to respond quickly and aren't always watching your email inbox.

How It Works

When a new submission is received on a form with SMS notifications enabled, Basin sends an outbound text message to the phone number you configure. The message includes the form name and, optionally, key details from the submission.

SMS notifications are sent only for legitimate submissions — spam submissions are always skipped.

Setup

  1. Navigate to Forms → Your Form → Notifications → SMS.
  2. Toggle Enable SMS notifications on.
  3. Enter the phone number to send alerts to in the Send SMS to field.
  4. Optionally enable Include full submission data in SMS to receive all field values in the message (truncated to 612 characters / 4 SMS segments).
  5. Click Save Changes.
  6. Basin sends a text with a 6-digit verification code to confirm you own the number. Enter the code to complete setup.

Tip

Only one phone number can be configured per form. The number must be in a valid international format (e.g. +1 555 234 5678).

Moving a form to another account

SMS phone numbers don't move with a form. When a form moves to a different account, through a project transfer or the API, SMS notifications are turned off and the phone number is removed. The new owner can set them up again with their own number.

International Delivery

SMS delivery isn't guaranteed to every country. If you enter a phone number in a country we don't yet support, the verification text may not arrive.

If you don't receive your verification code within a few minutes:

  • Double-check the number was entered correctly, including the country code.
  • Try the Resend option on the SMS settings page.
  • Contact Support if the code still doesn't arrive - we can look into enabling SMS delivery for your country.

Message Format

By default, each SMS includes:

  • The form name (e.g. New submission on "Contact Form")
  • The submitter's email address, if present
  • The submitter's phone number, if present
  • A link to the submission in your Basin dashboard (turn off with Hide the link back to the dashboard?)

When Include full submission data is enabled, all text fields from the submission are included instead of the email address and phone number, formatted as field: value pairs, along with links to any attachments. Messages longer than 612 characters are automatically truncated.

Credits

SMS notifications use form credits from the same monthly pool as phone and email validation (see Validation Credits). Each SMS segment costs form credits depending on the destination country, and the SMS settings page shows the cost for your number. A message can use up to 4 segments.

If you don't have enough credits, the SMS is skipped and noted in the submission's log. You can top up credits from your billing settings at any time.

Limiting Texts Per Hour

If a form gets a burst of submissions, you may not want a text for each one. Use Maximum SMS per hour on the SMS settings page to cap how many texts Basin sends for the form: 5, 20 or 60 per hour, or No limit (the default).

Once the form reaches its limit, further texts that hour are skipped and noted in each submission's log. The count starts again at the top of every hour (UTC). Skipped texts don't use credits, and email notifications and other integrations aren't affected.

Tip

You can also change this setting through an AI assistant connected over MCP.

By entering a phone number and enabling SMS notifications, the account holder (you) consents to receive text message alerts from Basin when new form submissions are received.

  • Sender: Basin (usebasin.com)
  • Message type: Account notifications — automated alerts triggered by form submission events
  • Recipient: The Basin account holder who configures the phone number
  • Opt-out: Disable SMS notifications at any time by toggling the feature off on the SMS settings page, or by clearing the phone number field and saving. In the US, Canada and New Zealand you can also reply STOP to any message, which removes the number from your forms. To use that number again later, reply START first, then add it again on the SMS settings page. In other countries, email support@usebasin.com and we'll remove the number.

Message and data rates may apply.

Info

Basin SMS notifications are strictly account notifications sent to the form owner. Basin does not send marketing messages or messages to form submitters.
