Engage by Swastik: every WhatsApp chat, answered on time.
Engage puts your business on Meta's official WhatsApp Business Platform in about two minutes. Then your whole team works from one place: template campaigns to opted-in customers, a shared inbox for every reply, chatbots for the easy questions and an API for your own systems.

# delivered → read → replied, via signed webhooksBuilt for teams who sell and support on WhatsApp
Campaigns, conversations, automations and integrations on one WhatsApp number, instead of a phone passed around the office.
Shared team inbox
Every chat from every number in one live inbox. Assign it, leave a private note, reply with a saved answer and see how long the 24-hour window has left.
Template campaigns
Send approved templates to a segment, now or on a schedule. Audience size and exclusions are shown before you launch.
Automations
Welcome messages, keyword replies and a visual bot builder. When a customer needs a person, the bot hands over with the full history.
Developer API
One endpoint for every message type, scoped API keys, idempotency keys, signed webhooks with retries and errors that say how to fix them.
Template builder
Write templates with a live WhatsApp preview. Engage checks them against Meta's rules before you submit, so fewer get rejected.
Contacts & segments
Upload a CSV, match the columns and add tags. People who opted out are skipped on every campaign, automatically.
Analytics
Sent, delivered, read and replied per campaign as it happens, and failures explained in plain language.
Roles & access
Seven built-in roles, custom roles, per-number access and scoped API keys, so each person sees only what they need.
Your first campaign, today
You don't need a developer, an agency or WhatsApp Manager. Four steps, all inside Engage.
Your number

A template
Write it with a live preview. Engage checks it against Meta's rules first; most are approved within minutes.
Your contacts
Upload a CSV of opted-in contacts, match the columns and add tags. Opt-outs are skipped every time.
And reply
Launch the campaign, then answer every reply from the shared inbox with the whole team.
The messages customers actually open
Utility and authentication templates for the moments that matter, marketing templates for opted-in customers, and free replies inside the 24-hour window.
Orders & delivery

From one phone to the whole team
The WhatsApp Business app is built for one person on one phone. Once orders, enquiries and reminders pile up, chats get missed. Engage moves the same number onto Meta's official API without losing the app.
| Business app | Engage | |
|---|---|---|
| Who replies | Whoever holds the phone | The whole team, with assignment, notes and saved replies |
| Bulk messages | Broadcast lists reach only people who saved your number | Approved templates to opted-in segments, scheduled and paced |
| Automation | Greeting and away messages | Keyword rules, chatbot flows and handoff to a person |
| Your systems | No integration | REST API, signed webhooks and an MCP server |
| Reporting | Basic message counts | Sent, delivered, read and replied per campaign |
| Access control | One shared login | Roles, per-number access, 2FA and an audit log |
