Unified inbox for SMS, WhatsApp and email replies

Send a campaign and the answers come back on three channels, into three different apps, and at least one of those apps gets checked too late. The unified inbox puts every conversation on one screen. When you reply, the message goes back out on whichever channel the customer used.

How the inbox works

Threaded by contact

The whole history with each customer sits in one thread: what you sent, what they answered, across every channel and campaign.

Reply in place

Type in the dashboard and the answer goes out as SMS through your device, as WhatsApp, or as email, on the same channel the customer used.

AI auto-replies

Auto-reply rules answer routine questions (hours, prices, directions) right away, and incoming WhatsApp messages can get AI replies. Every automated reply stays visible in the thread.

Your real number

Pair your Android device and customers text the number they already know. The message lands in the inbox, not on a spare phone.

Campaign replies included

Send a campaign and the replies land on the same screen, whether that is a "YES", a "STOP" or a question about stock. Each one is logged and ready to answer.

Open to your systems

Incoming messages are available over the REST API and pushed by webhooks, so you can feed them into your CRM.

Common questions

How do SMS replies get into a web dashboard?

Your paired Android phone forwards every SMS it receives in real time. When you reply from the dashboard, the message goes back out through the same SIM, so the customer sees a normal text from your number.

Does auto-reply take over my conversations?

No. Rules only answer what you set them up to answer, and every automated reply is visible in the thread. You can step into any conversation at any point.

Can my team use it together?

Yes. The inbox is part of the dashboard, so anyone with access to the account works from the same conversation history and can see what has already been answered.
