Two ways to get a number: let Linxi provide one, or connect your own carrier
Search & Buy a Number in Linxi gets you a managed number with the carrier and A2P registration handled for you. If you connect your own Twilio account instead, the Twilio steps here follow Twilio's redesigned console at 1console.twilio.com as it was when they were written; Twilio may move things since.

Sending Your First Message with Linxi

Once your number, webhooks, and contacts are all in place, sending is the easy part. Here's the three ways to do it and how to read what happens after you hit send.

1

Three ways to send

  • Individual — open a contact's thread from the Linxis tab and send a one-off message
  • Reply — respond directly to an inbound message in the same thread
  • Campaign — send the same message (with personalization) to many contacts at once
2

Sending an individual message

Open Linxis, pick (or search for) a contact, and type in the thread the same way you would in any messaging app. For a US 10DLC number, this needs an approved A2P Campaign first: US carriers block texts from unregistered numbers (Twilio reports this as error 30034), even to a single number you've messaged before. Linxi warns you when your workspace isn't registered yet, but it doesn't stop you pressing send — the carrier does.

Creating your first campaign

  1. Go to Compose & Send
  2. Choose your channels with the checkboxes — 🔗 Linxi Network (ticked by default), 📱 SMS, 📧 Email, and 💬 WhatsApp where it's set up. Tick as many as you like; for a text message, make sure SMS is ticked.
  3. Select recipients — everyone, a specific group, a list, or a tag
  4. Write your message
  5. Preview it, then send

Understanding delivery status

A message moves through Queued → Sent → Delivered. "Queued" means your carrier (Twilio or Telnyx) has accepted it but hasn't reported delivery yet; "Sent" means it left the carrier; "Delivered" is the carrier's own confirmation, which arrives via the status webhook (see Webhook Configuration) sometimes several seconds to a couple minutes later. Undelivered means the carrier rejected it — check the Flow tab for the specific error code the carrier recorded.

💡 "Queued" doesn't mean something is wrong — it just means the carrier hasn't confirmed delivery yet. For an approved A2P campaign this usually resolves to "Delivered" within seconds to minutes.

Why nothing delivers before your Campaign is approved

US carriers block texts from 10DLC numbers that aren't registered to an approved A2P Campaign — not just Verizon, and not only some of the time. Until your Campaign is approved, sends fail rather than wait. See Troubleshooting and SMS Error Codes for error 30034, the code this shows up as.
