Customer marketing automation for growing Indian businesses — WhatsApp, SMS and Email campaigns that run without a marketing team

We already send WhatsApp broadcasts manually — what does setting up marketing automation actually add?

A manual WhatsApp broadcast list treats every customer identically, goes to everyone at once, has no opt-out mechanism (TRAI requires one for commercial messages), and gives you no data on who opened, clicked, or purchased after receiving the message. Marketing automation adds four things manual broadcast cannot: audience segmentation (send the Diwali offer only to customers who bought in the last 90 days; send the reorder reminder only to customers who typically repurchase every 45 days), TRAI-compliant consent and opt-out management (so you are not building DND liability), occasion automations that fire per customer without manual effort (birthday messages go out on each customer's birthday, not in a batch), and an ROI report that tracks whether a campaign actually drove revenue. The difference is between blasting a list and running a retention programme.

We run a retail store with 3,000 customers — can Varisya set up customer marketing automation for us without us needing a dedicated marketing team?

Yes — this is exactly the buyer profile the system is built for. Varisya configures the Campaigns module against your billing data (customer list, purchase history, product categories, visit frequency), sets up the audience segments, builds the initial message templates in the channels you use (WhatsApp Business API, SMS, or both), registers your DLT templates with TRAI/your telecom provider, configures the occasion automations (birthday, X-day-since-last-visit, approaching reorder threshold), and hands over a system your team triggers with one approval step — no marketing background required. Ongoing changes (new templates, new segments for a product launch, seasonal campaign setup) are handled by the Varisya engineer on your annual retainer without a new project quote each time.

Do we need to register our business with TRAI (DLT) to send SMS campaigns, and does Varisya handle that?

Yes, every business sending commercial SMS in India must register on the Distributed Ledger Technology (DLT) platform mandated by TRAI — this covers your business entity, your sender ID (the 6-character alphanumeric name that appears on the recipient's phone), and every message template you plan to send. Without DLT registration, messages are blocked before delivery. Varisya walks you through the DLT registration process and helps you frame templates so they are approved on the first submission (template rejections are common when the wording is unclear or contains prohibited terms). You hold the DLT account under your own business entity — Varisya cannot register it on your behalf, but can prepare all the documentation and template wording. The SMS gateway account (Fast2SMS, MSG91, or similar) and the WhatsApp Business API account are similarly held by you; Varisya connects and manages them from within the Campaigns module.

How do the audience segments work — do we have to manually upload a customer list every time we want to send a campaign?

No — the Campaigns module reads from the same billing and customer database that Varisya Books and the POS run on, so segments are built from live data, not from uploaded spreadsheets. Varisya configures the segment rules once: for example, "customers who purchased in the last 60 days and have not visited in the last 20 days" or "customers whose total spend in the last 12 months exceeds ₹10,000" or "customers who have bought from Category X but never bought from Category Y". When you run a campaign, the segment is resolved at send time — so if a customer was inactive last week but came in yesterday, they move out of the re-engagement segment automatically. You do not maintain lists manually. New customers added to the system by billing appear in segment queries the moment they are created.

What does the ROI report show, and how do we know if a campaign actually drove sales?

The ROI report connects campaign sends to the billing records created in the days following the send. For each campaign, the report shows: number of customers in the segment, number of messages delivered (channel-confirmed delivery for WhatsApp Business API and SMS gateway), number of customers from that segment who made a purchase within a defined attribution window (typically 7 or 14 days), revenue generated from those purchases, and estimated campaign ROI as revenue-to-send-cost ratio. Because the Campaigns module shares a database with the billing and POS system, the attribution is automatic — a customer on the campaign list who makes a purchase in the window is logged without any manual reconciliation. You see, per campaign, whether it moved the revenue needle — not just whether the message was opened.
