Twilio

Communication

Send SMS, make calls, and manage your communications infrastructure — Neotask puts OpenClaw intelligence behind every Twilio interaction.

What You Can Do

SMS & MMS Sending

Send text messages or picture messages to any phone number worldwide. Specify sender number, recipient, message content, and media — OpenClaw constructs and dispatches the API call instantly.

Bulk SMS Campaigns

Send personalized SMS to large contact lists with variable substitution. Describe the campaign parameters and recipient list — Neotask handles batching and rate limiting.

Voice Call Triggering

Initiate outbound voice calls, play pre-recorded messages, or connect two parties programmatically. Useful for alerts, reminders, and two-factor authentication flows.

Delivery Status Lookup

Check whether a message was delivered, failed, or is still in transit. Pull SID-level detail or summary reports across a messaging service for a given time window.

Phone Number Management

Look up available Twilio numbers by area code or region, purchase new numbers, or update the configuration of existing numbers in your account.

Try Asking

  • "Send an SMS from +1-555-0100 to +1-555-0199 saying 'Your appointment is confirmed for 3pm tomorrow'"
  • "Send an MMS with the product image to the customer at +44-7700-900123"
  • "Check the delivery status of message SID SM1234abcd5678efgh"
  • "Send a bulk SMS to all phone numbers in this list with their personalized confirmation codes"
  • "Trigger an outbound call to +1-555-0150 and play the 'account_verified' TwiML message"
  • "Look up available 415 area code numbers in San Francisco"
  • "How many messages did we send yesterday and what was the delivery rate?"
  • "Purchase a new Twilio number in the UK for our London support line"

    • Pro Tips

  • Always include the full E.164 phone number format (+country code) to avoid routing errors.
  • For bulk sends, specify the Twilio Messaging Service SID rather than a single sender number — it enables smart number pools and better deliverability.
  • Use "check status" before resending to avoid duplicate messages — OpenClaw will look up the original SID.
  • For voice calls, reference a TwiML URL or named script rather than trying to describe TwiML inline.
  • Delivery rate queries work best with a specific date range: "yesterday," "last 7 days," or an explicit date.
  • Ask for "opt-out list" to see numbers that have replied STOP before sending a new campaign.
