Transactional messaging
Order updates, alerts and account notifications — messages a customer is expecting because of something they did.
Channels
Six channels. One dashboard.
Reach customers wherever they actually pay attention — and keep every send compliant with TRAI and DLT rules without becoming an expert in either.
01 — Channel
Bulk SMS
SMS is still the only channel that reaches every handset in India without an app, a data connection or an opt-in prompt. We run it properly: registered entity, approved headers, approved templates, and the right DLT category for the kind of message you are sending.
Ask about Bulk SMSPromotional campaigns
Offers and announcements, sent under the consent and timing rules TRAI applies to advertising.
Sender ID & templates
We register your six-character header and every content template on the DLT platform, then keep variants approved as your copy changes.
Delivery reporting
Per-message delivery receipts, failure reasons and campaign-level summaries you can export.
Inside Bulk SMS
Two categories, two sets of rules.
Promotional and transactional traffic share your entity registration and your dashboard, but TRAI does not treat them the same. What you may say, and when it may go out, changes with the category the message is registered under.
Category 01
Promotional SMS
Promotional SMS is the marketing route: offers, discounts, launches and invites going out to a list rather than to one customer. TRAI classifies it as advertising, which is why it plays by stricter rules than anything else you send — recorded consent, and a delivery window that closes at 9pm. Inside those rules it is still the cheapest way to put an offer in front of a few lakh people at once.
- Sending window
- TRAI restricts promotional delivery to 9:00 AM – 9:00 PM.
- DLT category
- Promotional. Recorded subscriber consent is required before you send.
Where it is used
- Festive and seasonal offers
- Discount codes and flash sales
- New product or branch launches
- Event, webinar and open-house invites
- Win-back campaigns for lapsed customers
- Enquiry drives for real estate, education and healthcare
Consent on record
The promotional category is built around subscriber consent. We set that up with you at registration rather than leaving you to discover it at the operator.
Written for the stricter review
Offer copy is reviewed harder than service copy is. We draft your templates to read as an offer and still clear approval.
Campaign reporting
How a campaign did once it went out, summarised per campaign rather than left as a list of individual messages.
How you actually send one
- 1
Upload the list
Bring your contacts in as an Excel or CSV file, exported from wherever you already keep them.
- 2
Pick an approved template
Choose the registered promotional template you want this campaign to go out on.
- 3
Send or schedule it
Send it now, or set it for a date and time inside the hours TRAI permits.
Category 02
Transactional SMS
Transactional SMS carries messages a customer is expecting because of something they did — an order placed, a payment made, an appointment booked. Because it serves the customer rather than sells to them, TRAI does not hold it to the promotional sending window: it goes out at 3am if that is when the order shipped.
- Sending window
- No time restriction on genuinely transactional content.
- DLT category
- Service Implicit, or Service Explicit where the message carries any promotional element.
Where it is used
- Order confirmation, dispatch and delivery updates
- Payment receipts and failed-payment alerts
- Appointment and service reminders
- Banking, insurance and policy notifications
- Ticket, booking and reservation confirmations
- School and college notices to parents
Templates with variable fields
Order IDs, amounts, names and dates are registered as variables inside an approved template, so one template covers every order.
The right category for the content
Slipping a promotional line into a service message moves it into a different DLT category. We keep the two separated so neither gets held up.
Delivery reporting
Delivery status per message, against the order it belongs to.
How you actually send one
- 1
Register the template once
We draft the message with its variable fields marked and submit it on DLT, so every send against it is already approved.
- 2
Send from a sheet
Upload an Excel or CSV export for a batch — every order dispatched today, say — and its columns fill the template’s variable fields.
- 3
Check the report
Delivery status per message, matched back to the order it was sent against.
02 — Channel
OTP SMS
An OTP is only useful while the customer is still on the screen waiting for it, which makes it the one message type where timing is the whole point. It is registered on DLT under its own service sub-category, separately from your marketing and notification templates, and it is not held to the promotional sending window.
Ask about OTP SMSVerification across your funnel
Login, signup, password reset, payment confirmation, KYC and document e-sign — anywhere you need to prove the person is holding the number.
One template covers it
A single registered template with a numeric variable field serves every code you send, so a change to a signup flow does not send you back to the operator.
Registered as OTP content
Submitted on DLT under the OTP sub-category and kept separate from your promotional and notification templates.
Delivery visible per message
Each code carries its own delivery status, so a verification step that is not landing is something you can look at rather than guess about.
03 — Channel
Bulk Email
Email costs a fraction of SMS and carries far more detail, but only if it is authenticated properly. We set up your sending domain, warm it, and give you the same upload-compose-send flow you use for SMS.
Ask about Bulk EmailDomain authentication
SPF, DKIM and DMARC records configured and verified on your own domain so mailbox providers trust your sends.
Campaign & transactional
Newsletters and offers alongside receipts, confirmations and password resets — separated so one never damages the other.
List hygiene
Bounce and complaint handling with automatic suppression, keeping your sender reputation intact.
Opens, clicks & bounces
Per-campaign engagement reporting so you can see what actually got read.
04 — Channel
WhatsApp Business
WhatsApp is where your customers already reply. On the official Business API you get a verified business profile, rich templates with buttons and media, and a real conversation thread instead of a one-way blast.
Ask about WhatsApp BusinessVerified business profile
We handle Meta Business verification and the green-tick application, plus your display name and profile setup.
Rich message templates
Images, documents, quick-reply and call-to-action buttons submitted for Meta approval and kept in sync.
Two-way conversations
Customer replies land in a shared inbox, so a campaign can turn into an actual support or sales thread.
Chatbot & automation
Automated flows for FAQs, order status and lead qualification, with handover to a human when it matters.
05 — Channel
Voice & Call
Not every audience reads. Voice reaches customers in regional languages, in low-literacy segments, and in moments where a ringing phone beats a notification.
Ask about Voice & CallVoice broadcast
Pre-recorded campaigns dialled out to your uploaded list, with answered, unanswered and duration reporting.
Missed call service
A dedicated number for opt-ins, lead capture, verification and voting — the customer calls, disconnects, and you get the number.
IVR & toll-free
Multi-level menus that route callers to the right team, with a toll-free or virtual number as your public line.
Short & long codes
Keyword-based short and long code numbers for inbound SMS campaigns and subscriptions.
06 — Channel
RCS Messaging
RCS is what SMS becomes on a modern Android handset: your verified brand name and logo, rich cards and carousels, suggested replies, and genuine read receipts — all in the default messaging app, with automatic SMS fallback when a device does not support it.
Ask about RCS MessagingVerified brand sender
Your logo, brand name and verification badge shown in the native inbox instead of a six-character header.
Rich cards & carousels
Images, product carousels, suggested replies and action buttons that open a URL, dial a number or share a location.
Read receipts
Delivered and read status per message — visibility SMS has never been able to give you.
Automatic SMS fallback
Handsets without RCS support receive the SMS version instead, so nobody is missed.
What you get to do with it
Your contact list is already a campaign.
Bring the file you already keep your customers in, choose a template that has been approved, and send. There is no setup project in between.
Excel & CSV upload
Bring your contacts in as an .xlsx or .csv exported from wherever you already keep them — a CRM, a billing system, or a spreadsheet somebody maintains by hand.
Saved contact lists
Keep the audiences you send to repeatedly — customers, leads, a branch, a city — instead of hunting for the same file every month.
Approved template library
Your registered DLT templates in one place, so a campaign goes out on one that has already cleared approval.
Scheduling
Set a campaign for a date and time instead of having somebody sit and press send at the right moment.
Regional languages
Write in Hindi, Gujarati, Tamil or any of the other Indian languages your customers actually read.
Delivery reports
What was delivered and what was not, per message and summarised per campaign.
Included with every channel
DLT registration and template approval, handled.
Indian commercial messaging runs on TRAI's DLT framework: your business has to be registered as a Principal Entity, your sender ID registered against it, and every message registered as a content template before a single SMS goes out. Get any of it wrong and your messages are simply filtered.
We do all of it for you — entity registration, sender ID, template drafting and submission, and re-approval whenever your copy changes. You send us your PAN, GST or Shops & Establishment certificate and an authorisation letter; we handle the operator portals.
