Last updated June 15, 2026
SK Form Builder can send SMS or WhatsApp messages when a form is submitted to you (admin notification) and/or the customer who submitted the form. This is powered by Twilio.
Available on Pro+ plans.
Prerequisites
- Create a Twilio account and get an active phone number.
- For SMS: a standard Twilio phone number
- For WhatsApp: a WhatsApp-enabled Twilio number (requires Twilio WhatsApp approval)
- Have your Twilio Account SID and Auth Token ready.
Global setup
Enter your Twilio credentials once in Global Settings they apply to all forms.
Global Settings → Twilio:
| Setting | Description |
|---|---|
| Account SID | Your Twilio Account SID (found in the Twilio console) |
| Auth Token | Your Twilio Auth Token |
| From Number (SMS) | Your Twilio phone number for SMS (e.g. +15551234567) |
| WhatsApp Account SID | Twilio Account SID for WhatsApp (may be the same as SMS) |
| WhatsApp From Number | Your WhatsApp-enabled Twilio number |
Per-form SMS settings
After global credentials are set, enable SMS per form:
Form Settings → SMS Notifications:
| Setting | Description |
|---|---|
| Enable SMS Notification | Toggle on to activate SMS for this form |
| Admin Phone Number | The phone number that receives the alert on each submission |
| SMS Template | The message body supports merge tags for field values |
Example SMS template:
New form submission from [customer_name].
Email: [Email]
Message: [Message]Merge tags follow the same format as email merge tags see Merge Tags.
Per-form WhatsApp settings
Form Settings → WhatsApp Notifications:
| Setting | Description |
|---|---|
| Enable WhatsApp | Toggle on to activate WhatsApp for this form |
WhatsApp messages use the same Twilio credentials configured in Global Settings and are sent from the configured WhatsApp From Number.
WhatsApp message templates
Twilio WhatsApp requires pre-approved message templates for business-initiated messages. Ensure your message template is approved in the Twilio console before enabling this feature.
Tips
- Test your Twilio phone number with a small test form before rolling it out to production.
- Use the Admin Phone Number setting to route notifications to different team members per form.
- SMS is best for brief alerts; use Slack notifications or email for richer notification content.
