Texting

Text your customers like a real conversation

Give your business a number people can text — send and receive over the API, or reply in the Line app while the AI handles the rest. We handle delivery, reputation, and the telecom red tape.

Everything you need to text customers well

Built for the way small teams actually work — fast replies, no jargon, nothing to configure.

Two-way conversations

Real conversations, not blasts

Every text is a thread. Customers reply, you reply back — all in one tidy timeline that anyone on your team can pick up where the last person left off.

Is the blue one still in stock?
It is! Want me to set one aside for you?
Yes please 🙌
Reliable delivery

Your messages actually arrive

We handle the routing, retries, and sender reputation behind the scenes so your texts land in the right place. You just see a clean delivered status.

Picture messages

Send photos, not just words

Share product shots, quotes, before-and-afters, or a quick confirmation image. Pictures send and receive right inside the same conversation.

Here are the two finishes 👇
Love the matte one!
Templates & automations

Write once, send a thousand times

Save your go-to replies, personalize them with merge fields, and trigger reminders or follow-ups automatically — without copy-pasting the same thing all day.

Hi {{first_name}}, your appointment is confirmed for {{date}}.
Thanks for stopping by! Reply YES for 10% off your next visit.
Quick reminder: balance of {{amount}} is due {{date}}.
Every reply in one place

AI handles it, or you step in from Line

Your Operator replies automatically — and when you want to take over, the Line app has the full thread ready. One number, one conversation, no context lost.

Actually let me check — can we do 3 instead?

Verification, handled for you

Texting US numbers takes a one-time business check. We do all the paperwork and submissions behind the scenes — you just confirm a few details once. The payoff: Higher delivery rates and fewer messages marked as spam.

For developers

Send a text in three lines

Prefer to wire it into your own app? One clean API and SDKs for every stack. No telecom setup, no approval queues to babysit — your key works the moment you sign up.
