Connecting SMS via Twilio

Connecting SMS via Twilio

SMS in wrrk runs on Twilio. You'll bring your own Twilio account.

Connect Twilio

1. Sign up at twilio.com (free trial includes $15 credit)
2. From the Twilio console, copy your Account SID and Auth Token
3. Buy a phone number in the Twilio console (any country with SMS-capable inventory)
4. In wrrk, go to SMS in the sidebar
5. Enter the SID, token, and phone number
6. Click Connect

Sending an SMS

After connection, the SMS page becomes a contacts-style inbox:

• Left — list of contacts you've SMS'd, sorted by last message
• Right — thread for the selected contact

Type your message, watch the character counter (SMS splits at 160 chars per segment — each segment counts as a separate Twilio charge), click Send. Delivery status updates in real time (sent → delivered, or failed with an error code).

Importing contacts

To kick off an SMS to a new contact:

1. Add them to the CRM first with a phone number
2. From the contact detail page, click Message > SMS

Or paste any phone number into the New Conversation field at the top of the SMS page.

Costs

Twilio charges per segment, per region. Typical: ~$0.01/segment in the US, more for international. wrrk doesn't mark this up — your Twilio balance is consumed directly.

Compliance

In the US, A2P 10DLC registration is required for business SMS. In Twilio's console, register your brand and campaign before sending high volume; otherwise messages will be filtered by carriers.

Troubleshooting

• Status: failed, error 21610 — the recipient replied STOP; they're opted out
• Status: failed, error 30007 — carrier filter; check A2P registration
• "Number not capable of SMS" — your Twilio number is voice-only. Buy a different one with SMS capability
