Every customer-facing SMS template — day-before reminders, on-my-way texts, review requests, overdue invoice reminders — needs two things to fire:
- The Messaging addon is active on your subscription.
- Your business has been A2P 10DLC registered and approved.
Until both are in place, SMS templates show as Locked or Pending on the Automations page and don't send anything.
Step 1 — turn on the Messaging addon
- Settings → Billing (owner-only).
- Under Addons, find Messaging.
- Click Enable and complete Stripe checkout.
Messaging is $39/mo. It also unlocks the Messages inbox and enables inbound SMS. This addon is separate from Voice and AI Receptionist.
Once Messaging is active, SMS templates flip from Locked to Pending A2P — you're not done yet.
Step 2 — register for A2P 10DLC
A2P 10DLC is what US mobile carriers (Verizon, T-Mobile, AT&T) require for any business texting from a local number. Unregistered messages get filtered or blocked.
- Go to Settings → Phone → Messaging setup (or click Complete setup on any Pending template).
- Fill in the A2P form:
- Legal business name
- Business type (LLC, Corporation, Sole Proprietorship, etc. — S-Corporation is a tax election, not an entity type; pick your registered form)
- Business address
- Website / online presence
- Sample messages you'll send
- Submit.
Review takes 1–5 business days on average. You'll see the status change from Pending → Approved on the page.
Once approved, every SMS template that shows Pending flips to Ready. Turn on the ones you want.
Step 3 — turn on the templates
Automations. Each SMS template shows a toggle:

- Ready (green) — flip it on.
- Pending — either checkout or A2P isn't complete yet. The CTA tells you which.
- Locked — Messaging addon isn't active.
Toggling a template flips the underlying automation from Draft to Published. It starts firing on the next matching event.
Special case — the review-request SMS
The Review request template needs one extra thing: a Google review URL in Settings → Business. Without it, the template stays locked (no point texting a link that goes nowhere).
What about outbound-only SMS from a page?
Sending an ad-hoc SMS from a customer's page also needs the Messaging addon + A2P. If you can send a manual SMS from /messages, you can turn on SMS automations too — the underlying requirement is the same.
