Built on the official Cloud API

No middleman. No shared numbers. No markup.

Your business connects directly to the official WhatsApp Business Cloud API. We don't resell numbers, we don't pool messaging volume, and we don't mark up conversation charges. You see what Meta charges, billed at cost.

Your own verified number

The phone number you use is registered to your business and verified directly with Meta. Not pooled, not shared, not rented.

Your own templates

Templates are submitted and approved under your business account. Edit, version, and version‑control them inside BulkMessageSender.

Direct, transparent billing

Conversation charges flow from Meta to you, at cost. BulkMessageSender earns from the platform fee only — never the message volume.

Use cases

Built for every industry that talks to customers.

From a one‑woman jewellery brand in Jaipur to a 30‑clinic dental chain across the country — the playbooks are different, the platform isn't.

D2C & e‑commerce

Order updates, cart recovery, COD confirmation, post‑purchase reviews — all on the channel customers already check.

Education

Admissions follow‑up, class reminders, fee receipts, parent broadcasts — without WhatsApp‑group chaos.

Learn more

Financial services

OTPs, statement alerts, KYC nudges, EMI reminders. Compliant templates, encrypted transit, audit log.

Learn more

Healthcare

Appointment confirmations, reports ready, prescription refills. HIPAA‑style consent built in.

Learn more

Logistics & travel

Booking confirmations, live tracking, gate changes, delay notices — in the customer's language.

Agencies

Manage 10+ client workspaces from one console. Roles, billing splits, white‑label reports.

Teams that switched to BulkMessageSender.

A few of the founders, marketing heads and ops leads running WhatsApp on BulkMessageSender.

"
The previous tool felt like a 2015 ticketing system bolted onto WhatsApp. BulkMessageSender felt designed by people who actually answer customer DMs. Switched the whole team in a weekend.

Set up was 11 minutes. Eleven. The Meta verification went through the same evening. By Monday we'd already recovered ₹1.4L of abandoned carts.

The pass‑through pricing alone saved us ₹40k a month versus our previous BSP. The shared inbox is the cherry — agents finally stopped DM‑ing each other "who's replying to this?".

FAQ

Questions, answered.

Can't find what you're looking for? Mail us at hello@serves.in — we reply in hours, not days.

No — we'll walk you through creating one during onboarding. If you already have one, even better, we can migrate your existing number and templates over.
Meta charges per conversation, by category and destination. We bill you the exact rate Meta charges us — every invoice line shows Meta's rate and our zero markup.
Yes. If the number is currently on regular WhatsApp or another BSP, we can migrate it. Migration is free and takes 15–30 minutes once Meta clears the request.
BulkMessageSender is an authorised WhatsApp Business Solution Provider, but it's an independent product. We're not owned by, endorsed by, or sponsored by Meta. WhatsApp is a trademark of Meta Platforms, Inc.
Every invoice is in INR and downloadable as PDF. We're a registered MSME (Udyam) and don't currently add GST on the platform fee. We accept UPI, Net Banking, cards, and NEFT/RTGS for enterprise.
Yes — every BulkMessageSender workspace exposes a REST API with idempotency keys, signed webhooks, and rate‑limit headers. Code samples live in our API docs.
Data is stored encrypted at rest in our Mumbai region. SOC 2 Type II report and ISO 27001 are available on request. On the Scale plan we offer dedicated tenancy and signed DPAs.
Cancel anytime — no minimum contracts on Basic or Pro. Your number, templates and contacts all belong to your Meta account, not ours. We export everything on the way out.
