What you can do with SMS

Bring your own gateway

Credentials are encrypted. Custom HTTP gateways are supported with a template for the request.

Built for India's DLT

Store sender IDs, DLT template IDs and entity IDs, and send variables in the order your template expects.

Segment counter

See characters, GSM-7 or Unicode, and the number of SMS each message will cost before you send.

Delivery reports

Signed delivery callbacks update every recipient. Delivered and failed events can trigger automations.

Opt-out handling

Per-contact SMS opt-in and a suppression list keep you from texting people who said stop.

The last-mile fallback

SMS works on every phone, so it is the natural final channel for WhatsApp and Arattai fallback.

Works with your other channels

Every channel shares one contact list, one inbox where replies are possible, and the same automation builder.

Email

Send newsletters and campaigns through Amazon SES, Brevo, Zoho, Gmail or any SMTP, with DKIM signing, one-click unsubscribe and bounce handling.

Arattai

Connect your Arattai Business account, sync approved templates, send campaigns and answer replies in the same inbox as WhatsApp.

Smart fallback

If SMS cannot reach someone, the next channel in your order takes over.

How it works

Questions about SMS

Do I need DLT registration?

For commercial SMS to Indian numbers, yes: your business, sender ID (header) and templates must be registered on an operator DLT portal. Your gateway provider helps with this.

Which gateways are supported?

MSG91, Fast2SMS, Twilio, Vonage and any provider with an HTTP API.

How is cost tracked?

Set a cost per segment on the gateway and every campaign shows its total.

Start reaching people on all four channels this week.
